The heli lost total and complete control. The pilot was standing 30 ft from the heli as it dove in. The heli uprighted itself once it hit the ground and continued spinning what was left of the main rotor blades. This went on for aprox 5 minutes until it gradually spun off the runway and into tall grass which bogged down the motor enough for us to cut everything off manually.

When we got the heli back to the pits we carefully checked part by part... everything worked except one thing.... the switch... there was NO POWER going to the RX. Battery was almost fully charged and all connections were tight. We direct wired the battery to the RX and magically everything came back on. All the servos worked and the RX worked without any glitches.

I understand that there is the possibility that something else could have come loose and then RE-TIGHTENED on impact but what are the odds. The switch showed no damage from the impact but yet we could not make it work no matter what we tried.

If it looks like a duck, walks like a duck and quacks like a duck... it must be a duck. That's the methodology we use.
