RE: JEPE PYRANHA
I am on my third Jepe Pyrahna and love this bird.
I upgraded the servos on the tailerons/elevons and increased them by 1/2 ".
The result, with 35% expo for elevator and aileron, you get a marked improvement in response rate.
Also, if you are worried about weigth make a bigger wing, I added 4" to the wing and have the Het 2W20 Jeti 70 and Flight power 2*2S1P 3700 so weight is near the 950g mark but if you line her up from about 200 ft out and just let it sink in it lands at a reasonable pace.
