Hybrid Glow and Electric in same aircraft
 

I have a Model Cessna with two glow engines.... one push and one pull... I want to put an electric on the rear push firewall.... So a combined Glow on the front and an Electric on the rear (pushing) I believe the model Cessna is a 337 (?) with one glow engine in the front and one glow in the rear... in a pusher mode... My question is how do I connect the ESC with the receiver to have two throttle functions... The ESC is a 40 amp with BEC.... Should I try to use one battery for the electric motor and one battery for the servos... ? Thanks... Richard

You can get away with 1 battery but I would use a separate BEC, not the one in the ESC. Disconnect the power line on the throttle lead from the ESC, You can use a y-harness but I would recommend using an AUX channel with mixing instead. That way you can set different endpoints, idles and throttle curves for the two kinds of motors.

... because otherwise you'd have two (voltage) captains on one ship.

Don' t remove the red pin completely, you may need it again in another plane.
