I have an SPE 26 I was actually considering putting in this plane but after running it on a test bench I think it may be more than the plane can handle. I wasn't looking to overpower it, I'm simply trying to go to mostly gasoline engines. Now that the 20EI has come out, I am seriously considering this engine instead. It looks like it will fit inside the cowling with little to no cutting and it should provide plenty of power.

The only issue I can think of (that I have taken care of already) is having the receiver that close to the engine. This is assuming you place it where the plans suggest. I have decided to put the receiver back behind the rear seat and have moved my rudder and elevator servos back to the rear of the plan. Hopefully this will help reduce any interference caused by the electronic ignition.

Later,
Russ
