We call it a critter. Its a foam wing that fiberglassed. with a gutter pipe for a fuse. Basicaly a fast flying wing. We used to make the allot about 10 years ago. decided to put one together again.. Its got about a 48" wing or so. fuse is only about 18"long.

I am thinking a 10x7 and if it is clean enough maybe a 9x9 or 9x10.

We race them in the World Models T-34 around here. The AX will not turn as high as the FX but seems to have a lidttle more torque. Your best prop on this type of aplications seems to be a 10 X 7, maby a woodie. The 10 X 6 was the prop of choice on the fX, some could pull a 10 X 7. I have been top dog in this club class for the past 4 years, but my engine of choice has been the TT Pro with a 10 X 6 apc. Our speeds with the TT and OS are very close, I pull out a lead in the first few laps, the OS guys close toward the end of the race, don't know why, maby just geet lazy. Your best advantage you can get will be practice practice practice, turn close to the pylons as possible and get that heading to the next pylon correct. ANY corrections in flight will cost you some time and distance. Set up your radio to make good tight turns at full up so all the turns are almost the same. Keep enough expo in the ailerons to make the bank slow enough to set up the turn right on, no down or up movenent in the turn. May tale a little time to get used to the setup, but well worth it in results. EnJOY

With the stock muffler or the light weight MAC muffler you have shown there - 10x6 or 10x7.

You might also consider a 9x8. A 9x7 is ok, and it turns it well, but the AX engine needs just a littttttle more prop than the older 46FX did.

The engine runs well and has pretty good torque, but does not have the carb size or porting for huge rpm. So prop it to run around 15,000 - 15,500 peak ground rpm. Up to 16K rpm is ok too (engine is not going to break). Back off about 500 rpm for flight. Engine will use the torque it produces to unload right into the sweet-spot while in flight.

Hi!
Try the new British RAM props...better than APC (at least over here in Q-500 where we race stock .40 engines and 10x6 or 10x7 propellers ).
