RE: LT-40 is REALLY REALLY close!
I bought two props, an APC 11x6 and 11x7. I will probably start with the 11x6, and if I break it, or get ready for a tad more speed, I'll put on the 11x7.
Tonight, I am going to start dropping all of the electronics into the thing. I need to mount the servo tray and so on. Hopefully by the end of the weekend, it'll be "done".
