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

It's a 20 incher and weighs in at 140 grams RTF. Will maiden today if the skies clear from all the fires to the south of us.

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!!

Flies great. Need to adjust a CG issue. Will 'try' to do a vid.

Was this the first one?

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.

Where did you find this one?

Did a google and it showed up.

Been working on a smaller Bee racer as well.

A hungarian punkrock band with a german name at a festival in belgium!. That was europe in the 90`s!
