Don't really think a twin will fit without cutting the cowl. I was thinking the same thing when I had mine. If you set up the rudder servo in the tail as I did mine, the extra weight is not an issue. The friend I sold mine to put a DLE 35 on it. It flew ok. Not spectacular but enough power for basic stuff. It is too bad that the RCG 50cc has been discontinued. Truly, that was my very first gas motor. I put it in a GP Edge 540. That plane was an animal and I put 55 perfect and trouble free flights on it. Motor would usually start first flip every time. The gent that has it now up Wenatchee way is still flying that motor and plane. Looks as new as the day I sold it. And that little motor is still chuggin' away like new. The RCG 50cc will turn the same size prop as a DLE 55. Mind you, that Edge came in at 16 pounds. See if you can locate one of those. That is a thought for you.
