Since you are going to use a glow engine, why not use a micro reciever, some of those 2 gram linear servos, or get the board that has two on the RX already with a BEC

or since you are already orange RX use something like these

The Orange RX micro rx can be fed 1s lipo without a BEC

The micro servos are small enough that you can go "full house" with ailerons, but that will take 2 more servos.

I CAN tell you that these tiny free flight designs converted to RC require very light wing loading and balance very similar to when they were free fight.
