It appears most of them are out of stock, including the recommended JR's. I am using MPI servos for this bird, and have used Hobby People servos in other planes and never had a problem. the only thing the JR's have over all the others is the high torque rating, which is probably why they are $60 each where the others are $28 each. The other downside is the retracts are designed specifically for the JR servo, anything else I would have to open up the area the servo fits in a little, by about .03". I looked at TH, but they are all on back order, but do see the JR's in stock at a few online shops, so I may just bite the bullet and pay the extra $60something for the Jr's to get it done.
