I am currently building a Model Airplane News plan designed by Paris White for a DC-3. The plan suggests using two .50 to .60 two strokes. I am thinking of taking this project a little further but I need some input from some of the more experienced engine guys out there. I would like to also build a matching scale Dakota or Horsa glider to tow behind (take off, releasing the glider in flight, with another piolt landing the glider). I do not know if something like this has ever been done or considered before, but if so, would I need to ramp-up the engines some, and if so, what would be a good starting point? I have no desire to break any speed records while in flight, so I am looking for something that will comfortably get the glider off the ground. This is a project that I will be taking my sweet-old time to complete, as my workload in my profession will not allow me to devote a huge amount of time at any given time to work on it.

Thanks for the suggestions-
Mark
