Landing gear Frame: Its very hard to do this as it says in the book by drilling through from the outside. Luckily I got it more or less right. I would have drilled the holes in the landing gear frame first and then used a tight fit angle kit to drill through these holes from the inside out as it were.
Connecting the trim motor: I used a molex I would have felt better with a DSub on a solid bracket.
I made a cradle which supported as far back as the flaps. I should have made one to support right to the tail. my tail is lower by 1/2" on the LHS. It doesn't affect the flying but I can see it even if other can't.
