Hi guys,
I am selling a Kontronik HeliJive 120A Version 12. This is off a Kasama Dune and has had about 60 flights. Never been crashed. ESC is in excellent condition. Includes 2 servo leads and heatsink.
The only part of the sticker missing is the version number but V12 is shown on the box it came in.
Price drop - now $350 posted.
SOLD thanks
Thanks.

Please share your knowledge/thoughts.
I want your opinions about two phenomenons I observe in 450 class with 325, 335, 360mm blades.
First:
In FFF (fast forward flight) 450 at some speed goes abruptly up. To avoid this higher RPM can be soulution.
My explanation: blade going back stalls. Heli does not fall on its side because there is 90 degrees displacement of reaction on rotor (gyroscopic precession).
Second:
With 325mm blades I can flipp very fast. Probably twice per second. With 360mm blades when I try to flip very fast heli reacts as if there was aileron mixer, falls...
