RE: APC props
APC props came out the year I finally bought my first radio (1989). So, I've been using them since I've been flying r/c. At my club, it was amazing how quickly most folks started using them. Most of the seasoned pilots at my field talked about them like they were the greatest thing since working carburetors.
The next time a Tower coupon coincides with a purchase I'm going to buy four or five of the ones Graham listed. I've got my Sure Shark dialed in good and I'm getting very consistent engine runs with the reedy. At exactly 10.25ozs it's the best test bed I have for trying out these exotic APC's. It will be fun to spend a couple of hours running them back to back to find which one "feels" the best. FWIW, I hate the APC 6x2, on my airframes, anyway.
