David,
thats only the case in the "flaps down" position. When the servo pulls the flap up, its more of a 90 deg between the arm and rod, and the servo is holding the flap up on power. ... either way, on the down or up position, you have a servo "holding" under power ... non digitals work best here. There is no need for a digital, as speed and precision are of no consequence over that of a good analog servo ..
I believe DG and JohnMac are correct.
Also, If I were to be in your shoes in the above "quote", I'd definitely be going digital as digital has the "Holding" power you need with deployment. The Analog servo will not have the holding power as good as digital and you will get blowback.
just my .02c
