Hi, great blog you have, I have been pouring over it as I intend to build the same a/c with same ( o-235 ) engine so am particularly interested in your build. Not too happy that you were required to add so much ballast in the tail to compensate for the o-235. I have been thinking about what I could put in the tail to help this. I have seen reports about oil canning on the fuselage on the 750, what about adding some additional "L" angles to make what would be essentially and "X" on the fuselage sides/bottom?
Also I have been reading the checklist on the MD-RA website and it mentions that the doors need to be able to be opened from both the inside and outside, how do you think your forward door latch will go with the inspector?
Keep up the great posts, can't wait to see it flying and your report on how the 235 performs.
