Thanks, It's "been a minute" as they say, so I just went and weighed it for an accurate number. 14lb-10oz. (surprisingly right in the middle of their range even with the heavier engine) (I'll update the description too for future reference)

I intend to get lower, and explore the maneuverability, not sure if any Timber is built for speed though.

No, just some pics and comments in the RC Groups thread I linked in the description

Yes, the differential thrust is on a switch, only activated for spins 😜. th-cam.com/video/T12aTHNEmjQ/w-d-xo.html"]th-cam.com/video/T12aTHNEmjQ/w-d-xo.html[

They are 9oz tanks. Should be plenty since it will throttled back most of the time. No damping, although certainly no electric motor, these engines run very smooth, especially for a single cylinder. The wing construction looks very "normal" for a balsa model, it's not super lightweight and I think will have plenty of strength. Time will tell I suppose.

Do you know if 1 of these engines would be good enough power to put where the electric motor is? Also how did you find the proper mounting angle for the motor?

@@Bruc3the628 I would say it would be doable, but not what most of us expect. (so could be a disappointment) I flew a GP Escapade 61 with one of these engines, and I think it was about a pound lighter than the Twin Timber. It flew fine for a sport plane, but nowhere near unlimited vertical. The problem was it also needed a lot of nose weight to balance. In the Twin Timber I mounted the engines at zero, no down thrust, no side thrust. That kept it easy to make perfect and symmetrical. These engines spin an APC 13x6 at 11,000 RPM, so compare that to most 6S electric setups, and it's definitely less power.

Thanks Adam. It's hard to tell who is a troll and who is just misinformed. I don't mind having a debate and a civil discussion even with differing viewpoints, but it rarely stays civil anymore :(. This hobby has changed drastically with the advent of BNF and RTF models, all it takes is money now with very little knowledge, combine that with an always on internet connection in your pocket, and a society that rather post off the cuff for the world to see instead of doing a little research first and things go downhill quick!

@@brianbrotherson5529 Regardless, when they put it like an A hole...they are an A hole. Lol. I send those morons to the "hide user from channel" file. No more issues out of them. Obviously, when someone is intelligent and respectful...fine, happy to agree to disagree. With a troll, it's their way or the highway.

I started with a RTF habu but I currently have 2 vintage balsa kits. I'm in the process of building. I have 2 60size 4stroke nitro warbirds that I'm finishing up as well. Im also currently getting a older QQ Yak 54 35cc gasser so I can put a smoke kit in it for my youngest son, it's all he wants to see is a smoke show. I love your setup only thing I'm not fully sold on is the nose I like them more on the pointy side but that's just me. Plus trying to cover a sharper point im sure is more difficult. I can't wait to see this in the air. Nice job.

@@jamesscheid7512 I wasn’t sure what to do with the nose. I thought about using the stock cowl and mounting a spinner with no prop. But with the scale exhausts, all the cooling holes and the stock spinner it would have been too original looking. It would have looked like it was just missing the motor, rather than a purpose built twin. Still waiting to fly it, but I will post a video of the maiden. Good luck with your projects and kudos for sharing the hobby with your son!

@brianbrotherson5529 that makes sense, though. But me and all three of my kids run rc planes and trucks. I got them hooked on trucks first, then I got into flying then they started going with me and now there wanting planes lol.

E-flite is a brand name. 🤷‍♂️

Its now much better. Twin gas would be a bit cleaner.

@@johna.s.3847 True, but also heavier. My opinion is that anything smaller than about 30cc it's not worth it. You have the same size and weight ignition module and batteries (times 2 in this case) regardless of the engine size.

I originally thought that too, however Tower Hobbies coupons worked for the Timber SWS, (and HH rewards) they never did for Hangar 9 stuff (this is E-flite branded) I had a 20% coupon, which made it "only" $50 more than the 30cc Ultra Stick. For that $50 you get something that arguably looks much better, has some style, clear windows, included lights, and pre-glued hinges. (no one wants to do do ANY building these days) That 20% would have saved even more on the BNF. I'm not a Spektrum guy, but everyone says the included electronics in the BNF are good and it's an additional savings. (The BNF also has installed pushrods, control horns, decals etc, lots of "fiddly" stuff for the instant gratification crowd :). Yes it is expensive, but anyone who has built an 80" plane and bought all the components can see the value. I spend nearly $100 just in wood to build the nacelles! Granted I have some leftovers for other projects, but I didn't realize how much balsa has gone up, it's no wonder everything is foam.

Yes it has differential thrust! (I don’t think it’s a first)

@brianbrotherson5529 probly not.. I'v never seen it but that's not saying much. Still cool tho. Did you know the sws timber was coming out or are you just really efficient at covering? Takes me forever to choose colors nevermind cover a whole plane..

@@jakeclauson9863 I didn’t know ahead of time. It was a very last minute decision. I saw the specs and figured it was about right for the engines I had. I had a few days off from work and put in some long days so it seems quick, but still took a lot of time.

@@brianbrotherson5529 nice, looks cool. Good luck!

Thanks, The cowl is PLA. I haven't had any issues yet. The radial runs pretty smooth, so that helps prevent cracking, and all the heat is in the cylinders which are out in the breeze. There isn't much heat in the crankcase, and it doesn't actually touch anywhere, so far so good!

Yes I have flown it only with the 17x8 since that first day and it performs well. I may try the 18x6 again just because the larger prop looks better. I might look for a different 18x6 to get the look, but with less load.

@@brianbrotherson5529 ok thanks for the feedback.

I can send you the file and you have it printed locally.

It's a great airplane. We also have the E-Flite Draco and Cessna 150, both of those arguably have better fit and finish, (paint, scale details, etc). But the Flex 170 is far more capable!

I never timed it, but it wouldn’t be very impressive with the severe lack of traction.

@@brianbrotherson5529 in those Case Always a rollin start. That one sec does Not Count. I think with 180 HP IT makes about 12 sec to 100 mph

@@brianbrotherson5529 but please your honest experience: how does it feels with those short wheelbase? How is breaking and fast cornering? Is those Car stable on the street? Is it as Dangerous as people say?

@@all_out_of_bubble_gum The short wheelbase never made it feel squirrelly, it's the limited slip diff that will get your attention. Cornering and heavy braking is fine, but a 2 lane road, with ruts in the pavement, and oncoming traffic will get your attention. Obviously just cruising is fine, but WOT in that situation and it would change lanes unprovoked, I think without an LSD it would just light up one tire and you'd still have some steering.

@@brianbrotherson5529 Many thanks 👍

LOL, I’m considering buying a new canopy, making it into just a windshield and having an open cockpit. It would suit the sound, speed, and style of the airplane better. It’s certainly no racer or big time aerobat.
