I am building a LT-40 with a few changes.I am putting the airlon sercvo's in the wing,should I lay them on their sides under a hatch or just cut a hole and put them in right side up like some of the arf's do,like the Tiger Moth?Does it really matter?Thanx for any help you can throw my way ctdave

I would put them in right side up (or actually, upside down) instead of doing the trap door thing. While the door is nice, it's a fair amount of work that may be worth it for an advanced model (I did it for the elevators of my 27% Extra 300 but not for the ailerons) but for a trainer, it would be way more work than necessary IMHO.
