Flew a couple flights today with a APC CF 7.2x8, and it flew alright but couldn't quite get it to unload in the air, could have been a little rich I guess, engine was only warm to the touch when I landed, so it wasn't overheating or anything.
Anyhow may have to lean it a little more or trim more off the header, I know FF has used the 7.2x8.25 on his DD, but its a OS VXDF, the newer OS DF version, a little more high performance than the VRDF I have, so thats why I'm trying a prop with a little less pitch, 7.2x8.
All in all my first experience flying a F5d Pylon Racer went well.
