John,
I took the PT Profile to a hard surface field and did some ROG. Slight breeze, the rotor spun up good, when straight down the runway and just when up very smoooth.. I now see why the 1/32 shim is put on the hub, but had to question it. The OS 15 pulls it right along.. I tryed an APC 8x6 and it did not like it so I used a Master Airscrew 8x4 and that was better.
I did make a bad landing and the Hitec 125MG stripped (Looked like Aluminum) so I replaced it for now with a full sized MG.
May get in small flights later today depending on storms in the area.

Jim
