I have a new OS Max 25 FX with a tuned pipe system in mind something with more detail with an enclosed bubble canopy and big pam steering the thing.
APC makes a 7.4 x 7.5C black carbon Q40 prop I was thinking on reshaping down to 6 x 7.5 if at 21k unloaded on the pipe 150mph.
- engines recommended rpm range / rated for continuous duty up to 19k and at 18k it makes .9 hp. If set up to unload at 19k 135 mph.
