8411?? that is waaaaaaaayyyy over kill (although it would work no problem). I've used the Cirrus CS-80 there with never a problem. It's a 130 ounce servo analog metal gear and absulutely bullet proof for that application. Cost??? $19.99 at my LHS and I'll be glad to send anyone who wants one for $25.00 by paypal.com to try out. I used them on the flaps of my isobar and they were great in that application as well.
