The Bird of Time is an awesome airplane. Designed by Dave Thornburg (the old buzzard himself). It is the easiest sailplane to fly I've ever flown. It almost flys itself when properly trimmed. Yes the ARF should have been covered with orange monokote on the bottom of the wings instead of white. I can't recommend this design enough. Spoilers - yep, you need spoilers; I lost my ARF trying to get out of a strong thermal; lost the right wingtip panel and couldn't control it well enough to save it. I built a kit version which is a better plane all things considered, but it takes time and money to build it. Putting a motor in the ARF is a great idea as you need the nose weight and it might as well be power rather than the chunk of lead that comes built into it. Very little overall weight penalty to add the motor. These things fly like homesick angels. You'll love it.
The Bird Of Time was designed by Dave Thornburg in the 70's as an FAI competition ship. At the time, a speed run was required but this was later abandoned because of too many wings folding. The larger outer wing panels are designed to help it turn tightly for spot landings. Not an easy scratch build, but a gorgeous bird in the air!
LMAO 3 MEETERS.haha. As european, I appreciate this David. Thanks. lol
YEET!!!
Has anyone successfully installed an FPV camera on this bird?
Yours is 41 ounces? I weight all the pieces of mine plus the battery, mine is 67.8 ounces! Even after adding the motor and battery I still had to add a ton of lead in the nose.
3 meters. Favorite FliteTest moment!
Deal with it :)

"I don't know where they're going... they don't know anything..."
LMAO :D
Great review, beautiful plane! Nice engine add
My favorite FliteTest video to date. LOVE the action shot when David puts on his sunglasses.
This is a great show guys. Flight Test is creative, interesting, and fun. FYI Dave Thornburg designed the Bird Of Time - he also wrote Old Buzzards Soaring Book - A fun read for anyone interested in sailplanes. It was very poetic to see it soar with the buzzards in this episode.
never got bored by this episode, though i've been watching this hundred times
6 years later I still love this beauty
I recently discovered this channel and I have to say what a beauty it is. My compliments to the whole crew of FT for such amazing footage, humor and informative video's. And u guy's actually encouraged me to buy my first RC airplane! So big thanks to you, and if all is well in the future I might even drop by your shop to support you guy's.
p.s. I usually get annoyed by all the commercials and stuff in some of the vids on YT, but you guy's do it in such a way that I don't mind it at all KUTGW!
Its 2016 and My first flight with my Bird of Time resulted in the wings breaking in half 3 minutes into the first flight. I was in a loop when it happened. Tower hobby Replaced the plane n/c and I fiberglassed the new birds center wing section!
I cant stop laughing 3:48
Bike rats lols!
It was awesome, followed by an epic burn to Americans (I am American, but I still shake my head at our insistence to keep a death-grip on the Imperial system)
Then he says 41 oz? WTF? KG? Grams?
Savage

wow, I LOOOOVE having david on the show. he just adds so much... awesomeness to the show. by the way, don't let him go home next year. lock him in a cupboard, do whatever you have to do. he's NOT allowed to leave.
hello, I live in France and I watch all your video test, you are genials!
thank you for everything.
thanks to you I was able to buy the "dynaflite bird of time" exceptional glider.
thank you pascal
Nice one guys. Loved the aerial footage. And the CSI sunglasses 'moment' was a HOOT!
Built one from plans with thin foil back in the 80's. I actually enjoyed hand cutting every rib in the wing. Hand carved the body. All white with dark blue wing tips and tail tips. Still my favorite.
High start-100' of rubber and 300' of 60 lb fish line.
3:50 lol @ David putting his shades on. YEEEEAH!!!!
A Josh Bixler action figure would be pretty cool i think, all the guys should get one :)
great episode keep up the good work :)
I set up a similar Bird of Time, with 5 degrees down thrust and 2 degrees right thrust, which quite nicely "power balances" the plane's aerodynamics. I also painted a good portion of the bottom of the wings BLACK! For me, that's necessary, for this plane easily goes very HIGH, and I needed the visibility. Mine is also four years old, and as good as new. It's a delightful flyer, but is quite heavy and you really need to anticipate making a turn, for it doesn't happen right away.
+Richard Ranney Oh yes! Really important! I put spoilers in the wings!
That IS a beautiful plane indeed!
The BOT is a classic, in any size, period!! I've had the 3M flavor with a fullhouse setup(spoilers, flaps, ailerons, rudder, elevator) and my 2M BOT 2ch R-E still was on par in all but the windiest of weather. It would be nice to see more sailplane reviews. But usually only the more advanced pilots are truly into that scene.
There's no way that the ARF weighs 41 ounces. Without motor they weigh between 60 to 70 ounces. The finished kit will weigh about 45 ounces. The cost may be the same between the finished kit and the ARF but the ARF will weigh much more.
What is Josh Scott's expertise..??
My step brother started the kit version of this back when we were kids in about 1974, he never finished the wings compleetly, so much forming and rib sanding for prep for monocoat, I asked if i could finish it because i was 2yrs older and had more builing exp, so instead of letting me finish it for him he forced all built and unbuilt wood parts wings, fuse ect in the trash compactor and turnd it on, I cringed with every pop and crunch. Jack was always an ass, and still is today. I was sad for the death of the kit. I got into slope soaring in the 90's and hung out at my fav flying spot of redondo beach for the decade. a friend once brought his bird of time and let me fly it, what a relaxing bird to fly, i loved it, just missed inverted flight and rolls but how it flew more than made up for it. I hope to get an ARF soon. really loved the way it flew. So to back up what you said, the ARF is better than the kit, the kit would cost more and always would have some imperfections from your build. It is a MASSIVE build, to the point of total fustration as proof with my brother Jack. BTW they no longer allow rc planes there, ONLY 10oz or less with no motor.

Plans - relive your youth.
Hey guys, are there guides for mounting the engine assembly onto the Bird of Time? Really interested in doing something similar here. Thanks.
I'm totally not into this type of craft but if I had money to burn I'd buy this in a heartbeat...for some reason this one has me excited...really neat bird
Great glider! Best ARF for the money on the market IMO with built in self leveling by design.... great machine for distance flying with incredible orientation visibility. And there's enough wood left on the tips to sand the tips to get the magic L/D like Dave Thornburg's. Not all BOTs fly the same. I've only seen one that was hand built really get "on the step" where the LD "really" flattens out and it was the builders 2nd or 3rd one and he said it was achieved from getting the tips just right. When you see that happen you see another level of performance. Wish Dynaflight offered it with the Monokote rolls but uncovered so you could glass the center section and add some balsa to the thick trailing edge and get it thinner for less drag and a tad more area that got sanded off and do the final sand yourself. A waste of time and materials to pull off the covering to do that. When I shipped mine from humid Hawaii to the mainland the wood shrunk so much I wasn't sure if it would re-shrink tight but it did using a heat gun NOT an iron. So expect a few wrinkles that is normal contraction of the wood from lower humidity level, not a defect. Factory did and amazing job on both of mine but again wish you get it uncovered so you could do the wing as you want it...spoilers, flaps, etc. But there's always the kit... and for the money you really can't complain.
Why would it be a waste of time and materials to take off the monocote and do it right.you would have one sweet sailplane.
edward hasiak Because once you take off the covering it cannot be used again and the BOT has a large wing that will require a lot of Monokote$$$. And it can take a lot of time, more than one evening to remove Monokote on a large sheeted wing depending on how well it was applied as it uses a high heat glue where the color (gray is the worst I've seen) often soaks into the wood and even solvent cannot remove it where it will show when using a transparent color that I prefer for visibility. Even areas of white left on damage the appearance of the wood you can see using a transparent covering. But yes removing the covering to re-glue the wing with CA, check for wood grain direction on the spar caps and correct if needed, and glass the center section for added strength and to protect the wing is the best way to do it.
Well, he would have got his turn, but David wrecked the motor...
3 Meters YEEEEEEEAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHH
Hey Guys, Can you make a tutorial on adding the motor?
Makes me want to go buy a Sail Plane - Radian anyone?
honestly, if i could put a .22 on it with fpv, that would be great,
A gun?!!!!!
AHHHHHHHHHHHHHHHH, DISARM THE MOTOR BEFORE PUTTING YOUR HAND IN THE PROP DISC AREA!!!!!!! Really would hate for anything to go wrong... a guy at the field I used to fly at got really chopped up one day while handling his electric park flyer
My BOT weights 82oz with all the RCairmods installed, with the upped and forward decks removed and HS85MG servos
Dear Flite Test. I've had this goal of wanting to fly a Dynaflite Bird of Time 35mi and back over a large body of water... How are such long distance flights possible with UAVs much less hobby gliders?
I would love this and a bixler 2! My first 2 planes I think! I don't know about putting a motor on it, I don't like modifying things - it's scary!
The wind is my friend. Use the wind. It helps you out.
Where I live you either fly in the wind or not at all. Use the wind to
your advantage. The wind will improve your takeoff performance (more
lift) and slow down your landings (more drag) when facing into the wind.
And if not flat, try to land uphill, wind permitting.
I'm building a second BOT and am installing an E-Flite 25 electric motor. I'm wondering what size and pitch folding propeller to put on it, and what brand. Anybody done this that can help? Thanks.
+Scott Gudmundsen I'd highly recommend running your setup through ecalc. My advice would be to select a prop that will put you right up at the current limit of your motor since you won't be using the motor a whole lot anyway. My personal preference in props is the Graupner CAM folders, however Hobbyking has started carrying molded carbon props for the same price range, and they're actually stronger than the Graupners. I definitely recommend selecting one of the HK aluminum spinners for it (Carbon blades and hubs are almost always sold separately).
+Scott In Colorado Look in RCgroups.com, where there are several electric BOT threads. I used a 13 inch prop, but don't remember the pitch. The battery was a 3s 3000 rating, needed for nose weight. Beautiful flyer!
'Actual authentic MonoKote' - I'm dying lol. I guess it makes me old (only 28) that I used to cover ALL my planes with MonoKote. Must be considered antique now.
very nice air to air shots. if david was flying, then who was doing them? what a beautiful plane!
Hi gents... Love the plane.. I've recently purchased one and would like to convert it electric. I would like to know all measurements and what size motor ect.. Please I need help... Thanks
I just got Bird of Time from Tower Hobbies. Unlike the review my mono-kote was dismal. It had tones of wrinkles anywhere the mono-kote was attached to planking. I have not checked for how true the wings are. I will see what happens as try to rework the mono-kote.
you guys almost smoked that bird on a flyby lol
so close they swapped paint on the flyby ...
Julian Begg well .. almost ... ;-)
Although this an old video anyone who wants to try build from scratch in Balsa there are plans out there from the original 1979 model

I flew my bird of time today, maiden flight! One tip. Make sure you tighten your propeller on good. My propeller fell off and then I had a dead stick landing, and it wanted to glide so much I had to try to make a turn. It lost altitude and crashed. :( But no damage! I searched for the propeller and found it! I will put it on youtube in the next couple days. Then later when it was calmer in the late afternoon I had a really long flight. It looked like a big air bus in the sky!
I am almost done. Had a couple more issues. After I glued up the wing connectors I found that the plywood pieces were not uniform and one connector was to thick. I started grinding down the alluminium but then I unglued the aluminum and cut down the wood, then re-glued it. Also my kit did not have the 36" pushrod so I can't finish it. Battery placement is a pain, I am making cross pieces so the battery will sit in the front above the rudder servo.
Most awesome people in the "World" listen to how Brotherhood should be ...Amen
Ooooooooohhhhh three meters wide :O Wish i had one right now. But with a smaller motor just to keep it in the air.
Josh I have a new bird of time arf fiberglass fuse. I'M having a hard time fitting a motor could you tell me your choices for motor, prop, esc thank you.
Also the instructions said to epoxy two little blocks for the elevator servo and then to remove the servo and use double sided tape to hold it. I found that method was impractical. I used CA to glue the blocks and CA to tack down the servo. Had to cut the clevis screw in part so I could shorten the elevator push rod more than it was meant to be shortened.
I Have snapped two of these mid air in a loop. Once in the center in the first 3 minutes, the second off to the side of the center support. I ran a pice of carbon fiber top and bottom on my third plane. Tower hobby replaced my first plane n/c.
hellooo,, i love this plane and want one so much, but please where can i get one??? i have searched online and cant find them anywhere.. can someone please help me find one or even find the motor assembly kit also?? thanks so much.. Craig
My scratch built BOT weighs 54 ounces and goes up like a rocket with an E-flite Power 15 and an aeronaut 11/7
3 meters! lol
The Bird of Time weighs in at about 80 oz., but this sailplane has no trouble soaring at that weight. Right from the write up on flite test.
flitetest.com/articles/dynaflite-bird-of-time
Boats. You should get into boats and other water vehicles. MAYBE some cars, but only if they are not your classic RC car.
What a great idea to throw a motor on this. You could fly forever on a warm sunny day. Thanks for sharing, maybe someday I will have one of these 3 meeeter birds in my hangar.
I have about 25 flights on mine now. This bird with a motor makes me nervous. It weighs a ton and it doesn't really have enough elevator throw to pull out of some stalls. When it picks up speed or stalls I am worried that something will break.
I ordered a rimfire .10 outrunner and and 35A esc for mine. I have no idea if it will be to little, or to much power. Also ordered a folding prop and hub. Have no idea if the hug is large enough, it is 45mm. Josh's hub looks larger. It will be a fun project.
Still not as good as "I landed it"
Hey Josh can you show us the inside how you got the battery to fit in the front? Did you move the rudder servo back or something? I am going to use thumb screws like you did to hold down the canopy.
You guys do some amazing aerial photography! You get some amazingly beautiful shots!
Youre right RCllama, alot of us feel the same, my last comment got lost in the deluge but I mentioned it would be interesting to have an episode about Dave's "origins" and how he learned and got so innovative with electronics. he's a tech geek but fun to watch and not boring or nerdy. and when he talks everyone listens and winds up learning something even if not understand it all lol.
I'm an old bloke in Australia would love to get one of those things is it possible to get one in Australia or sent to Australia and how much
Can you guys show us a video,On how you get your Aerial Videos,you know show us you are getting the footage, and how,and what plane or heli you are using to get your footage !!!
Please respond!!!
If youtube brings out the Payed subscripion fee to some channels are you going to make your flitetest channel so people have to pay a subscrition to whatch you flitetest videos? I hope not!
It really needs spoilerons to get it out of thermals. Mine is scratch built from plans and flies on a 3 cell 3548 979kv. My spoilerons run off the rudder and the rudder is on the aileron channel
josh bixler you never said what size motor you used, I want to get that glider I think it is beautiful. ron
Those stall at 5:25 is the lack on front weight, I made one and bought one ARF amd both have that terrible issue!
I always was just about to buy one but hated the hi start procedure. Can you give me the config and data on how you converted it to ep .I would love to have one like that.
Spoilers! You need spoilers on the BoT. Especially if you have tight landing space.
You are not going to warn us about how tender the center section is? What good is a review that doesn't mention the most important feature about a design?
LMAO! @ 3:47
Josh I bought this and it should be here this week. Do you recommend I cut the nose at a certain angle for the motor? Like down and to the right a tad?
Sailplanes forever. :) Got a chuckle about telling people not to build a balsa glider! My first build was a Goldberg Electra (basically a Gentle Lady).
I fly mine with a self-made power pod with an OS CVA15 & sub-micro servo for throttle. The thrust at idle cancels out the drag when gliding.
whoever is on the multi rotor camera almost gave me a heart attack like 10 times lol. also when is the David Spitfire going to be done?
love my bird of time . put an E-flight 15 on it 4.25 lbs flying weight.
what amaze me is that such a big glider doesn't have air brakes, but it seems that it slows quite well.
I saw this online for 160, but i want a 4 channel with rudder elevator and ailerons, as well as a tow release
come on guys he's Norwegian..... they were delivered as baby's by gliders
PLEASE do some FPV with the Bird.
yes I know that advertisement is needed, and I don't mind it. But some people do it better than others, like the guy's from flight-test. And KUTGW is internet slang, I would say make Google your friend!
p.s. Google is a very well known search engine on the internet, they will help you find almost everything on the internetss.
Can you buy this beautiful plane in Australia $170 That's impossible
I have one of them coming tower hobbies what kind of power do i need to get it in the air ? or is there a power kit i can get
Hey guys :). Would it be possible for you guys to use SI units in your videos, instead of the imperial unit system. Or at least show them as subtitles/annotations. No one in the rest of the world knows what the fuck 118 inches or 50 ounces are. Greetings from Germany ;)
Hey, even if you don't do action figures, what about pilot miniatures of each of you? I mean, for someone modeling the cockpit of a sailplane, what better pilot figure to stick in the seat than David? And put a miniature Bixler in my Bixler? You bet! Put a Josh Scott in my trainer? I'm in.
My first R/C build WAS a Gentle Lady! She made me look like a better pilot than I really was until that fateful day when I dorked the high-start launch and managed to destroy her...
I think I even still have the plans, but if I build another Lady, it'd be the T-tail Sophisticated Lady.
Josh Scott touched on a very important thing during the chat inside. He mentioned that because its balsa, its a higher maintenance plane. Which is very true in most cases because most balsa planes are still gas/nitro and they require a lot more work and set-up time...
i realized that all the ads on flite test happen at 7:00... wierd
do you remember about how much of the nose you had to cut off? what motor did you replace the one that burnt out?
3:47 has got to be the funniest thing on flitetest! I laughed soooo hard!
Awesome! I still fly my Bird Of Time that I built in the early 90s. Great fun. Dave Thornburg designed this Aircraft. You can find that plus some really cool reading about RC flying, aircraft design, philosophy, and funny ass crap in his book call: Old Buzzards Soaring Book, copyright 1990. After stumbling upon this book in Evetts Model Shop in Santa Monica: God rest good ol Cory's soul... I ordered the kit and got it in the air.
Find that book, it's almost like reading the -idiots book for how do you keep your Volkswagen alive.. Evetts Model Shop is still open for business, Cory's wife is still there, but there's some young bucks now working in the back doing stuff.. She is close to being gone to. Wow, going to Evans Model Shop for a little over 50 years. I fly my full-size sailplane, a LS3, regularly as well. All you RC soaring chumps need to get in a full-size ship with a soaring pilot and be amazed at how you will immediately lock in, take full control of the ship and freaking soar! Be careful, doing so can ruin your life, as you know it.
Don't forget... Get high and stay high. Capt.Nemo
Dave A. Thornburg designed the original Bird of Time in 1975 as a 3 meter sailplane and kitted it in 1979 before selling to Marks Models in 1980. The plans appeared in the January 1979 RC Modeler Magazine, and I fell in love with the design instantly. Dave also wrote "Old Buzzard's Soaring Book" in 1990.
Can you make a video of How to fly a Glider?? I have a HKing Fox but I don't fly it very well... I also have a several times crashed MPX Cularis :[. Don't know, maybe some flying techniques, advices, anything ...
hey my name is matti and im 13 years old i livein belgium and don't speak english very well.I have a question about installing the bomb drop with a switch on your transmitter.Can anybody tell me how to do this.
that's more complicated than you may think, mostly because it adds an enormous amount of weight with very little electrical return.
maybe in a few years when super thin, flexible solar cells come down in price
Hey guys you should totally try make a dollar tree foam board Glider Scratch Build video for all us sailplane enthusiasts. If there could be two versions a powered version and a none powered version that be really great!
Bixler bobble-head or better yet, one small enough to put into an airplane. My Bixler2 still has an empty seat.
When was this filmed by the way? Looks like it is still on the chilly side. Greets from Canada.
Bird of time is amazing to fly' every one at the flying field loves it, be sure to put 10mm wash out on the tip of both wings so it does not tip stall when you low to the ground... Especially if you learning to fly like me. Mine had wash in and stalled in a nasty way! I have a size 15 motor with 2 2200 3cell =4.4amp after 30min of flying I still have 50℅ battery life left- what a blast!!! Its very heavy at 2.2kg but takes for ever to land it. Some one claims they got 1.2kg on a kit' ARF starts at 1.7kg empty.
Check out my video on my channel Bird of time' landing in a cross wind
+Eddie Eloff Speaking of weight the boys reckoning of 42 ounces is the weight for the build it yourself kit version. No wonder David was impressed. Add about twenty ounces for the art. Must be all that Monocote and fibreglass. What do you think is best? For the best wing loading it has to be the kit. For build quality it has to be the kit. For adaptation to electric the same. I suppose its all that building that has people buying the ARF. For a glider that boasts that it can hold its own with a composite craft, it very reasonably priced.
+martin wilson I would say build the kit. If you have time. I think stock its bout 1.1kg but the ready to fly 1.8kg stock if you extend the nose by 10cm then you should drop 1 battery and the led weight. Making it easy for better thermal in. If you on a tight budget this is sure the best glider to buy at 3m long. Every one here loves it. A few complaints bout the weight but it still flies great. Few guys out there flying the same sort of setup on the internet.
