Hello everyone,
I built a new Sig Wonder last weekend and flew it today. This is the third one I have built. This one has a O.S. 25 FX and it flew a little faster than the one that had on older .25 FP. I have a 9x6 prop on it because the local hobby shop had a limited selection of smaller props. I know it has a lot more speed in it if I had the right prop. What size would be best for a .25 FX on a Wonder with speed, of course, in mind?
