Nice looking bird, Jim. I've always liked birds with a taper...think LOC Lil Diter, Expediter, etc.
Well, now I know what you were doing instead of attending the monthly SARG meeting yesterday. LOL!
BTW, next time you need to fit a washer over a recessed bolt, take a toothpick or dowel or length of copper wire and press one end of it to the top of the bolt. Then slip the washer over the toothpick (or whatever) and let it slide down onto the bolt. Pretty much works every time. It's an old shade tree mechanic trick.
I agree with your reasoning about going with the 29mm motor mount. 1) With our current launch field issues we may be flying only LPR and MPR for the next couple of months. 2) The G reloads are half as expensive as the HPR reload kits and you have a number of 38mm birds already. On my Tea-Bird 4.0 I went with a 38mm instead of the 54mm of the original. The designer never boosted on 54mm motors so why bother?
Speaking of low and slow, are you gonna fly the Minnie Magg next month at Snow? I've seen it fly on an H and think it's time for an I...
