Randy109,

Electric propulsion we cannot compare and I know what you mean.
It's funny but how about a sound generator in the plane so we not only smel the fuel put also hear the engine.
And of course the selectionswitch on the transmitter Webra - OS Max - OPS.
For a lot of the modelers the electrical propulsion is a good solution and has a lot of possibilities, fitting with your wallet.
