Clearly, you're looking to go gas on this one, but you run the risk of ending up with an evil-handling overweight airframe (can you say snap 232? ).</p>

To get good 3D perf, you really have to overpower while minding the weight build up. IMHO the best bet for this plane would be a OS 1.60 2-stroke with a 18X6 prop.</p>
