if you find you cant get two .250 lines, as in the dynon AOA, through the vans supplied snap bushings, its becaus they are .625-7s

i cant get the ones under my landing gear mounts out, butttttt, if i had it to do again, i would replace them all with sb .625-8s it was a tiny bit of difference but enough to get me past the hump that was kicking arse for an imbarrasing amount of time.

. for those of you building TD's you can. good luck
i only post this because i couldnt find ANY postings on the Dynon AOA lines. here or at VAF
