It is good to know , that clarifies many think in some design i have seen.

Wow, that really light. Wing load should be very good for a 3D. What ffoam and thickness did you use? Also what motor and prop?
Looking forward to see mainden.
Thanks for sharing!

It's built with 1/4" EPP, powered by a Racerstar BR1306/3100KV with a VGood 6A esc on 2S 450 lipos, 4 X 3.7 digi servos and a 6 ch Orange RX.

Got three flap modes dialed in to play with.

The skies are still yellow and foul smelling , supposed to blow away in a few hours. Hopin' !!!

The setup is ............. not measured, just eyeballed ..............

horz. stab at 0 degrees, the wing at 1 positive and the motor a few to the right and a few down.

My 24" Micro Blade 3D has the same gear and is 3.5 ounces RTF. Talk about big fun with a small model.

Although, building small and light is a big challenge and a lot of extra work. Worth it though!!

Not a CG issue, it's a decalage issue. Will adjust the horz stab and try again. Had the same problem with Trottel #1 that I built, as did my FB.

Also, going to change the motor to the 4000kv version and replace the motor mount. Printed ones don't work well, they're too soft to hold the tension against a tightened cap screw and constantly loosen. Back to aluminum or Lexan.

Wow!


I built a Trottel from Dollar Tree foam with the paper removed. I laminated all outer surfaces with clear laminating film.

Motor: 1806 - 2300kv
Prop: 5x3
ESC: 12a
Battery: 450mah 3S
Servos: 9g

Weight without battery: 178g
Weight with battery: 212g

I am new to RC having flown my first plane about 4 months ago. So, I dialed the rates for my Trottel back to 60% with 30% expo. I am absolutely blown away by how great this airplane flies. Yes, I crashed a little the first couple of flights. But, now I can fly it with ease and am having tons of fun. The graphics on my wing are to show my appreciation to Thomas for sharing such a wonderful design.
