here is the story. many radio controlled lite machines helicopter (1/2A heli) fans like myself have been trying hard to find a good replacement engine for the what seems to be the world's most durable rc helicopter.
however, the overheat of rc car engines in the helicopter is always somehting we cannot avoid. at the moment, i have a .12 rc car engine (Force .12) installed, it will run well to power the heli but will start to loose power after some time. it is undoubtedly due to the insufficient cooling of the engine body. so i am asking if anyone here could help me with a custome made oversized engine heat sink.
Could be a whole oversized heat sink or some extra fin body designed to 'clamp' on the exisiting one.
any input or advice will be much appreciated. I am based in UK. anyone nearby with the capability to produce such an unit?
