Sorry...dyslexia there. I meant 54x52. But I'm not sure there's a lot of difference there. I ordered the larger diameter because I'm not very worried about killing the prop (as long as I'm on a runway), and wanted to be able to cut it down if it wouldn't turn up high enough to develop power. I'll probably live long enough to eat those words, however. I had a 52x52 and it would turn up to something like 3700 rpm wide open, which is a little too much for my taste. If nothing else, this lends some credence to my theory that Ed's pitch numbers tend to be on the high side. I got three more hours on it last weekend, and probably 15 more landings. I tried to get Larry and Joe to meet me in West Virginia, but I got these lame excuses like "I'm sick as a dog and may die", and "Sorry, I'm on my way to California". Some people! Regarding the TruTrak ECO, It certainly is perfect for me. I refuse to waste another penny buying more MGL stuff (like $1500 for two servos to get two-axis autopilot out of the iEFIS), so this is a no-brainer, and light. I've requested dimensions, although it appears as though the servos should fit in a KR wing. Not so sure about the elevator though. See photo below (just to make sure I got it right this time). I was going to the hangar to re-torque the prop anyway, as well as adjust the valves again...
