I don't know the answer to your question (it should - says "any servo"), but I do think it's a heavy servo for such a small plane. I don't know what you need for your retracts, but the usual servo sizes in projects this size weigh a few grams, not 3/4 oz. I can't say it enough - this is a REALLY small plane for all the things you want to do with it. Every gram counts. Also, if you're on a small budget, you'd be blowing an awful lot of it on this servo. Jim
