I'm putting one together with an MDS68.

It appears to be about 8.5" ground clearance to the prop shaft so even a 13 inch prop should be ok.

Overall it looks pretty good for an inexpensive ARF.

Getting a wider engine entailed making clearance in the motor mount so it could go against the the upper nose gear block with clearance to get at the collar holding it in place. The engine is a tight fit and I'll probably have to cut up the cowl quite a bit.

I expect to have assembly done in a couple more days.
