Im a rookie!
I crashed my friends Lama V4 and am taking responsibility to fix it.
Basically i dropped straight down from about 25-30 feet, dont ask??
It landed flat on the gear on the concrete, broke the gear, and broke one of the wires off the main rotor motor, I re soldered it back on and thought everything was good until the first actual test flight.
The heli now has a really bad shake/vibration, i messed around with the gyro/mixer but i cant figure out what it is.
Does anyone have any sugestions as too what needs to be done or replaced to get rid of the horrible shake??
