Chainsaw Repair

They are for starting the chainsaw engines converted over to model airplane use.

The non reduction one (Megatron) though it will run on 24 volts, I use a 12 volt truck battery on it and it turns 2800 no load rpm @ 600 in-oz torque at the hub and draws 100 amp at that load.

The 4:1 reduction one (Dynatron), I have set up to use two emergency light batteries and it turns 2400 no load rpm @2700 in-oz torque at the hub and draws 20 amp at that load.

The reduction unit is a Miller 4:1 reduction unit. You can buy them to fit either starter.
