These ex-Jepe models are all offerings to the god of speed:

Pyranha impact at high Voltage station, only fuselage was allowed to go-in ! Leftovers 'high Voltage' Pyranha. Soldering of inline cells was squeezed -out. Mega 16/15/3 still OK! Tree hit by Spitfire or Spitfire hit by tree? This how it came of of the tree... F-16 impact, until today the NiCd battery is still deep in ground...

if you burn your controller it should be done properly so no further repair is needed!
