Following E-Bikes @ abandoned bobsled track

I took on the challenge to follow some e-bikes on an abandoned bobsled track... It involved some planing regarding rf propagation and all as there was no line of sigh but in the end everything turned out fine(except the crash) the Reverb was fine and flew right after a propchange, the GoPro suffered totalled back screen and front lens protection glass but still recorded afterwards. Gear used in this video: Rig: ImpulseRC Reverb 5“ ImpulseRC Wolf PDB(awesome) KissFC V2 KISS 32A T-motor F40PROII 2400 KV Uni
