I have had 2 Sagitta 600's (and now have a third). The stabilizer is always the issue with tails like these. On my first Sagitta the tail was very wobbly from drilling the hard block with a hand drill and not being very careful. The second one I drilled out the hard block with a drill press which came out much better. Still the brass tubing and piano wire arrangement left a lot to be desired. Even after roughening the surface of the brass tube and epoxying it into place which eventually worked loose. This time around, I am going to try a carbon fiber tube and rod arrangement, I am hoping the carbon fiber tube will hold better to the hard block. I built all of mine without spoilers mostly because I did not have a 4 channel at the time, but also once you got used to the speed range it was very easy to handle and land.
John my gut feeling is fix the stabiliser. It is such a beautiful plane that just wants to fly. It would be sad to crash or loose it for want of a little a TLC. Might make a good restoration video! All the best Allen
I would second the suggestion for a restoration video. I have a similar problem on one of my acquired gliders and would really like to see an experienced builder (John) solve this issue. Despite the wobble, I never noticed any issues when flying so I have left it alone. I am sure John’s solution would be simple yet very effective to stop the wobble. The two halves of the stabilizer can separate so I installed two very small elastics through the rudder to keep the stabilizer halves together.
The Sagitta 900 was a classic from the 1980's I think. However those all flying tails which were popular at that time caused more problems than they were worth. Definitely worth rebuilding the tail end.
Well, you're an excellent pilot. It's a pleasure to watch you soaring! When I start flying with a setup like your elevator, I for sure lose my plane...
John , I have a Sagitta 600 ,and a Sagitta 900 that grew to about 1200 by extending the wing to 3.1 metres span . I built these models about 25 years ago and flew them regularly for a number of years . Both were a delight to fly and placed well in thermal comps . Now however , they live in my shed and are not likely to fly again under my control . I'll probably give them to someone who appreciates pre-carbon epoxy machine made projectiles , if I can find the like .
The Sagitta is a potent machine, to be sure. I think this one should be stripped bare and rebuilt so it can live up to its full potential. At least, that's what I would do.
With the back end all tightened up, this is a great thermal-duration flier, although I'd prefer to change to a 7037 or a 3021 - just a little thinner for better penetration without having to drop in a lb of lead ...... I've flown a couple in competition and the Sagitta gives a good account of itself ...... :-) warmed my heart to see one on your slope ....
Makes me miss my smaller Sagitta 600 I built and flew in the early 90s when in my early teens. I still have a scar on my hand from a moment of bad judgment while carving the nose piece. Plunged a #11 X-Acto blade handle-deep into the meat between my thumb and forefinger. That aside, she turned out to be very beautiful. For the conditions at my field I preferred the flight characteristics of my Spirit 2m although it wasn’t the sleek beauty my Sagitta was. Good times
Just flipping marvellous to watch you fly sir!!! Thankyou and to your good lady for filming it, stay safe and healthy with my best regards from Alan in south Yorkshire 🤗🤗👍👍
John The wobbly stab was common on the Sagittas in the mid-'80s, some guys would put a 1/4" strip of balsa down both sides of the vertical fin to move the stabs out to eliminate the wobble, some made the brass tube pivot extend out into the stab and just built the stabs with the brass tubes in the stab moved outboard some. During the late '80s when the guys really started launching hard you could get rudder flutter so some got rid of the rudder counterbalance and just had a straight rudder hinge line. I had one, but I thought it wasn't great. The wing was too flat, putting another 1 1/2" of poly in the tips really made it turn better. The fuse was so small it made installing servos in it very tight, and the rear fuse was weak. I flew thermal contest so I tested dead air times, (5am, no wind), I consistently got 3 minutes 30 second times, with my Windsong I consistently got 5 minutes 20 seconds. The spoilers as designed were to far inboard, blanking the stab, and to far forward making the plane pitch down when deployed. I really like your videos, it would be nice if you included your flight evaluation of the plane at the end of the videos. Rich
Hi there Rich, it’s interesting to hear your thoughts on this model. I’ve only ever heard people say good things about it , but it’s not really my favourite design.
Definitely worth some TLC - it is still a good flier! My first reaction would be to put struts in, which would stiffen it up nicely. After a while, a conventional tailplane, beefed up and with large elevators. Many thanks as always!
@@leifvejby8023 The Bird of Time I'm building uses this very same set-up. I'm very mindful of this problem, making sure everything fits with minimum tolerance and NO binding. So far, so good.
@@leifvejby8023 Thanks for that info! I understand that compared to conventional tailplanes, with hinges that spread the load right across the stabiliser, an all-moving one will have forces concentrated over a small area. I'm interested to know what fixes were tried. For example, was the fin too thin and later thickened up? Or just more grp/epoxy reinforcement? I would still be happier going over to a conventional tailplane and elevator - the forces on the servo and pushrod would otherwise be a worry IMHO.
@@travelbugse2829 A sailplane is an exercise in efficiency. A full-flying stabilizer is more efficient than a separate elevator. The problem is most commonly caused by a loose fit of the rod and tube. Coat that area of the rod with solder and file or sand it down to a better fitment. The Sagitta was designed as a multi-task, competition sailplane, speed, distance, and duration. But for sport flying, a conventional tail will work just fine.
The Sagitta 900 kit came with 2 differing airfoils: one a Selig undercambered: the other is a flat bottom (Clark Y like) I'm pretty sure that yours has the Clark Y like airfoil because it handled the wind pretty well either that or the monocote voided the bottom undercamber. BION the flat bottomed Clark Y is far superior to the Selig airfoil on this glider: If that's what you've got Definitely refurbish it and put some ailerons on her too! If the airfoil is the flat bottomed Clark Y (like) I'm very envious! Robert
Thanks for this ! I am building one from the Outerzone-hosted plan, and so will be redesigning it to use a more conventional TP, as an all moving one gives rise to trepidation ....
I’d hang on to that glider you have and repair it. Of course it’s a mater of when and not if it will go down, but with your skill II think it could be around for some time.
it seems so .. throw a brick of that cliff and it will climb :-D and your Sagitta is an pretty old but beautiful and absolutely timeless classic :-) Floats wonderfull
Absolutely gorgeous as always! Your videos have inspired me to buy a sailplane of my own as I live right on a seaside cliff also. I found a second hand Great Planes Spectra ; any comment on those?
Beautiful old Glider, reminds me of my Spirit 100 and my slope Glider, I need to get in touch with you to help me find someone who can help me repair the old slop , I'm binge watching your videos and you have a wonderful collection.
I always laugh whenever I see instructions say "make sure the tailplane is perfectly straight and level, you make sure by (super complicated method)" because if you can still fly like this the it really doesn't matter what you do really
Its an olt free flight trick but build your tail and rudder crooked or kicked to one side and you will get nice wide circles out of plain with no input on controls...
John, I love watching your videos from my home in Arizona. Have you ever considered selling any of your gliders? Especially this Sagitta. About 20 years ago I used to win a few club duration events with a Sagitta 600. Loved that little glider. Unfortunately a winch event sent it to glider heaven. Too damaged to repair. Vintage gliders like the Elan, or the Bird of Time are incredibly rare here in the US and a Hobie Hawk is truly impossible to find.
Is it possible to still find plans for gliders? If so where? There a place here in the US picked up by a gentleman when another passed away but has yet to put any out. The hobby has all but gone out. My opinion is everything got over priced so it started going down hill and the clubs and the main hobby association have jacked up their fees. Now the Feds are changing everything making it Restrictive on altitude, unless you belong to a club that may get special permission. Gliders are meant to fly high and clash with powered aircraft because of slower speeds again that’s just my opinion.
I get all my plans for free off the Outerzone website. They have thousands of old vintage plans. I’m lucky to have a large format printer to print them out.
Beautiful flying for a windy day. I have a 600 that i crashed and broke a wing. I'm going to start rebuilding it. Since im stripping it down i might as well look on fixing the elevator. One of the other comment's suggested going to carbon fiber. You have any thoughts. Thanks for sharing!
Sounds good. Any weight saved down at the tail is definitely a good thing. The only disadvantage of using carbon fibre, is that if it is over stressed it will shatter and break, a metal rod will simply bend a little. Good luck with the rebuild.
Need your help, sir. I began building and flying 2 channel rc gliders in the mid 1970's. I've been searching on the internet for a glider I remember from that time. It was fairly distinctive. It may have had a fiberglass fuselage. I remember it only being available factory pre-built. The glider came in a foam box that was cut-out in such a way as to protect the curvature of each wing half. It was advertised in RC Modeler Magazine, and probably elsewhere also. The reason for this was because it did not have a polyhedral wing. Instead, the wing had a very graceful upward curve starting at about 65% out from the wing root. For the life of me I cannot remember the name or manufacturer. I am hoping you can help me. It may have been a high wing held on by rubber bands. But I suspect it probably had 2 wing halves that slid onto 2 metal rods fixed to the fuselage. The EZ Flight Radian and others now have curves wing surfaces, but 45 years ago this was not terribly common. this glider was not 2 meter as I remember it. It was 100" or more in wing span. My email is: john.vandusen@verizon.net. I have watched and enjoyed a number of your TH-cam videos. You seem to have close access to a reliable slope soaring location. Are you near Torrey Pines in southern California, or someplace else? Thank you!
One of my best gliders. On a certain day at a certain place, mini tornadoes whipping across a runway. The powered guys quickly landing; me, quickly launching into a thermal elevator.
If it were mine, I'd definitely fix it. Have you ever flown a discus launch glider ,John? They are amazing floaters. I look forward to your videos all the time. Thank you for you beautiful videos!
Gotta be on the sticks to know for sure but, I would suspect there's a considerable amount of trim changes with the stab flopping around like that. It needs to be fixed.
I noticed a lot of flexing or twisting of the rudder in turns; I am wondering if you ever found that to be of any concern or fault in that design of the Sagitta 900?
I got this model second-hand and it already had lots of slop and play in the tail surfaces. All-moving surfaces can be difficult to make without any slop and I think this one has just worn out over time. I’m not really a fan of the Sagitta but even this old model seems to fly okay.
@@SlopeRCGliders I recently bought a Sitar Special 100, and found that the leading edges of wings are slightly warped. I believe they can be corrected. This seems to be an issue with some vintage or old built planes. I do like the design of the Sagitta 900, but I have no experience flying one. From the number of planes you've flown, I am certain you know best of the quality and characteristics of each sailplane. BTW - I am still waiting to see you fly a Wanderer and a Sitar Special. Did you ever get the canopy you mentioned for the Sitar?

I had one of these John, and cured the stab problem by epoxying a washer either side of the tail. Worked like a charm, no more wobbliness!
I have one I built back in the late 80s still hanging in my garage, loved flying it , no slope so high start an thermals, was an awesome flyer!
She flies pretty well considering that stabilizer, but I couldn’t stop noticing the misalignment in flight after you showed it.
Hi John, it's like an old ruin but full of charm and seems to fly very well ... It deserves a good restoration.
it looks like it flies well but that stabilizer just makes my brain itch. it seems like it could tear away at any time.

No struts, they are drag. Just fasten the bearing tube, and it will be fine again - it was a common fault back when floating stabilisers was the norm.

good morning, do you have any advice to give to those who wont to start practising this discipline? with what to start and from what budget?
I'm sure you have thought stabilizing the stabilizer with a guide wire or monofiliment line.

Probably only about 15 mph.
Yea, I still have my Sagitta 600 from 40 plus years ago, I built mine with ailerons and flaps.
Wow, that's really wobbly!
🏆 Watching your videos is inspiring!!
Hopefully, my gliders will fly as good as yours one day.
What do you say after flying it , is it worth a restoration of flying stab mechanics ? Or fly it as is and build a new one ?
I’ve already got rid of it. I didn’t think it was worth my time renovating it. I’d sooner build a whole new aircraft.
BRAVO....
The Aquila had the same full flying stab. Both are/were Airtronics kits and were top of the line performers in their day.
Glad to hear about the stabilator issue, is it the pivot/through tube bearing surface do you know? I WAS contemplating building a t tailed model up til now...
Yes, because the bearing is only the width of the fin, any slop is amplified by the width of the elevator.
@@SlopeRCGliders is the structure ok? Also, could you apply something as a release agent "like a droplet of baby oil" to the tube then apply some cyanoacrylic glue around the tube and kick it to form a plastic, tight bearing?
The tail really shows up in the video , didnt expect it to , but it flys nicely.
May be you should ask the FAA ... but otherwise it flies well and might deserve a bit of care ... to serve years ... I like it.
You always make my day.

I'm not sure what you concluded about refurbishing it but it looked like a handful to me. Put it aside and do another own-design is my advice.
