I recently read a post by US F3A champion Andrew Jesky where he stated that he has flown glow (YS) powered models extensively and glow has a significant edge in power over e-power, yet he chooses to compete with e-power. In my opinion, YS does not need to increase power (and do they really need to run on 30% nitro?), rather, simplify the engine as much as possible to improve ease of operation, especially for novice glow pilots while retaining all their outstanding features (power, throttle response, low end torque, etc.). I’m a diehard glow guy and we’ll never achieve the plug and fly simplicity of electrics (though battery maintenance is their burden), but I hope there continues to be solid support for glow engines in pattern.
