Troy, for precision and pattern flying on my 140 sport, using 30% heli fuel, what prop would you recommend ??? The plane is still the same 9.5 - 10.0 pounds 72” Aeroworks Yak 54 that till now had been using the APC 18x6w for general fun and some 3D. Now I need something that will make the plane track a little better without gaining to much speed.
