Tiny Trainer Pre-maiden thoughts

[FlyingInTheSkies(for now)]

Hello guys I was just wondering what the flight characteristics of the Tiny trainer were as im pretty nervous for the maiden since I am imaginging absolute madness in trim and thrust angles after launch. M y scratch build was not very sturdy or perfect, and that I have actually used a modded fuselage that was one piece with a high wing look. This was because in my previos atrociusly crap build of the normal Tiny Trainer it was a mess with the fuselage and the wires. This mod was by @Todd Merril and is an absolute beauty. However, back to the problems. In my previous build the speed of the plane was way too fast and the motor was only a 2208 2400kv with a 6 inch prop (3s) which shouldn't be that fast. additionally, the handling was really unstable and stalls happened although easy to save. It was also extremly responsible to wind, and was pretty drifty unlike the flight demos in the build video and all other videos. Do any of you have expriences with your TTs? (sorry for this being so long) And if yes what should I do about them?

oh and yes the mod file of the fuselage from Todd.

That is A pretty big motor compared to what I used on mine. I used an 1806 2000kv motor on mine with a 6 inch prop on 2S 450mah and sometimes 3S 450 or 800mah battery.

Heavy is fast. Light is slow. The bigger the battery, the faster I had to go.

I beat the living snot out of my 3 channel TT for 9 years. My Buddy's daughter built it at Flite Fest '16, and I retired it at Flite Fest this year. Time for a new one.

This was some of the most Fun I had, flying in super gusty conditions LOL :

That 2208 will give it some power! For example, a similar motor on 4s on my radjet, would push it to over 100mph. (The radjet is much harder to fly and more aerodynamic)

WOW thanks yeah mine is a bit over powerd. I discovered that (again) today AS I HAVE DONE ITS MAIDEN!! lets goo. it was pretty straight this time in flight, which is an improvment. The speed becomes a little over at 70 percent throttle and i keep it at 50. The main problem was the weird drift to the left / right i forgot again. Most likley becasue of the thrust angle since I messed up the power pod make. Thanks for the advice and i will try to get it fixed!

Yeah the speed is mad but I should try down grading my power!

Oh yeah guys I have maidened it and it is pretty well imporved but for one problem: the plane drifts on turns and is pretty shifty to flying straight horizontally. These two should be because of the motor angle and the wing. SO the wing i used i did not included the dihedral so i could shove a carbon rod through. My question is how can i make a wing that is still rigid but with a dihedral? how should i reinforce it at the joint?

Obviously, the FT MS P-51 is a much different design, but it has ply spars on a wing with dihedral.
The build video might provide at least some ideas to help you.
The wing build portion of the vid begins at approx. 2:48:00.

Thanks! I'll be looking into that once i crash!

YO guys I did another test flight, this time checking to see if the minor changes to the thrust angle worked, which it did as the drift was greatly improved. This flight also proved once again how versatile the Tiny trainer is, handling shifting wind with ease. Next up will be a new wing with a dihedral!

EDIT: and yes only the very poorly built TTS will succumb to wind and a bad pilot. The norm's take EVERYTHING you throw at them.

I Mostly used the 3CH Dihedral wing with mine. By the time I built the flat Sport wing, the rest of the chassis was rubbery and in such bad shape, it didn't fly too well.
