The APC 10-5 is known to work very well on Fox .35 Stunts. Master Airscrew props are typically viewed with some scepticism, possibly because they are known to be
under the pitch rated. The APC's are sort of the opposite, but for a different reason. They are pretty close in pitch, but function as though they are higher pitch than labled, so stick with the 5". Zingers are pretty awful off the peg, but can be reworked to function ok if you have the time and patience. I hate the finish on them, as it gums up my sandpaper somethin' awful. Top Flite "Power Point" props are much better for "plug & play" use, but I can't say whether a 10-5 or 10-6 would work better. I'd try both. I would also highly recommend that you go through the Tower Hobby site and find the Thunder Tiger 10-5.5 Cyclone prop and give them a try...not many sizes, but very good props.
