I just purchased a Viper Temp guage that you mount to the engine and if gives an LCD readout of Engine temp it will also show the max temp reached during the flight.
I have a Raptor 50, OS 50, Cool Power 30% Heli fuel, standard flying for now.
I mounted the unit per instructions, What Temp Range should I be looking for?? High, Low?
I'll use (F) Reading.
Thanks,

David
