Hello everybody, i make that 2 edge video, and just want to post here my setup:
peakmodel edge 26cc
26cc rear carburator engine (no brand on the engine, it was sent to me for testing, i do not know who is the manufacter)
apc 17x6 prop 8100 rpm
4 futaba s3305 servos
1 standart servo for acelerator
6v 1300mah nimh batery

Have not weighted the model, sorry.

Very good airplane, for 3d flight and precision, lots of wing area, top quality construction.

Hope that helps

Jose
