Mitch,

I measured the MK plans digitally as I was a little puzzled by that gear location. I measured 5.35" at the root from the front of the LE to the gear axles which lines up just a little forward of the rear side of the gear servo.

I think your first photo with the pink angle ruler shows this measurement, just shy of 5.5". The CG is stated as 130-135 mm (min) = 5.12-5.31".

If the gear axles are located at 5.1" from the LE, they would actually be in front of the foremost CG position! The plane will rest on it's tail unless you make it quite nose heavy. The CG might end up being too far forward for good flight.

I'm sorry about this bad news.

David.

Edit: Ahhh! Never mind, I was measuring to the real LE of the wing, not that of the core. Apologies - all's good, whew!
