I wish we had more input on the other threads concerning the flip...very nice plane...but not much info coming through...anyone interested in this plane should check out the older threads...after putting some deep thought into it...i feel that the flying wires are not needed..but would like some input on the engine position...invert or 90 degrees.....i am going with the saito 72, but am considering the saito 100 after looking at the weight i will be adding...and if you mount either of these engines on 90, well there would be quite a bit of "stick out" i am just wondering why they suggest the 4-strokes on a 90 degree...
