The newer kit with the fan further forward is great. The benifits are two fold, it allows for saddle tanks closer to the C.G. verses the tanks behind the cockpit. Secondly, the fan is more efficient when placed closer to the inlet opening. Whether it's the sport or scale wing, I'd install the split flaps. This minor modification is well worth the effort and you'll enjoy the results on landing (speed and stability). I have the old version A-4 with the O.S .91 Dynamax, JMP pipe package, split flaps, and spring air retracts and it's a blast to fly. When I moved back to Albuquerque New Mexico I once again pay close attention to warm days with density altitude approaching 8000 on warm days. Needles to say June through September I don't fly it much if at all because of the reduction of thrust. I imagine if I were to do it again I'd install the RAMTEC for the added thrust. Enjoy the kit and watch for the wing waggle in flight, it's talking to you saying you pull much more on the stick and it'll be snapping.

Take Care,
Norm
