Poor horse-ee!

Yeah, the electric vs nitro discussion, poll question or simply discussing it, is pretty much beat to death not just in RCU, but even in other RC sites.

Hands down, LiPo & Brushless is very quickly passing piston and fuel very qickly. LiPo batts are already very light for their size and store tremendous amounts of evergy per cc of batt material (i.e. charge). Model engines will have to make radical changes to keep up or surpass electrics.

The easiest way I see model engines surpassing or at least keeping up with motors is to go multi-cylinder.

Another possibility is to find a new fuel. Nitro has very little BTUs per given mass, so going with a fuel that is somewhere between alchohol and gasolines in BTUs/mass might be a solution. Such a fuel will of course make a biger bang and create more torque than what nirto can for a given crank, con-rod length geometry. Of course, such an engine will need to be made of stronger materials to take th strsses of more BTUs being released.
