If I hade put a 4-stroke in mine it would be inverted and the70 is plenty of engine. 4-stroke don't mind being inverted, in fact I have four 4-strokes inverted in my A/C. 2-Strolkes are a different story. I did that once in a Venus 40. A nightmare. With the inverted 70 there will be very little cowl cutting. It will look and fly great.

The "N" version has the aileron servos burried in the wing and the belly-pan is not attached to the wing. Other than that, no difference.

I thaught I was getting the "N" when I ordered it but received the "A". I was going exchange it till I checked my model. The wings and fuselage were in such perfect condition I kept it.
