Hi, theguitar, I'm glad you're finding the RCU forums to be helpful!

I've flown Tower Pro 5010 servos before. I found that, while they did work ok, their operation was fairly crude and they didn't move in the smooth, small steps that I was used to with the brand name servos.

With the Hitec HS-311 standard sport servo available for $7.99 each before additional discounts at Tower Hobbies (quantity discount, dollars off for reaching various order totals, free shipping, etc.), I decided that there really wasn't any savings using an off-brand Hong Kong servo that might not perform as well in my trainers and sport planes.

You can sure try the Tower Pro 5010 servos if you'd like, but I'd wager they'll actually cost you more with shipping charges included than the cost of Hitec HS-311 servos. Why pay more for servos for which you'll also have a hard time finding spare parts? With the HS-311, you'll also be able to buy replacement gears, extra servo arms, and replacement servo cases if you need them. Finding those same parts for the Tower Pro 5010 could be much more difficult.

Good luck, and good shopping!
