Bud, as far as engines go. The Laser 200V is appx 33cc and is probably more comparable to the G38. Proctor, from my conversations with them, does not recommend a 2 stroke gassers for their planes because of the vibrations associated with them. This is especially true when it comes to the fixed magneto ignition gas 2 strokers. Some of the newer types of battery powered ignition gas 2 strokers seem to run much smoother and they might work fine. Take a real hard look at those Laser engines before you decide to go gas.
