A 2 amp bec should be good for you situation as long as your not "working" the servos to hard. I would say 3 amp, but as long as you are not doing flips, rolls, etc, you should be fine with 2 amp.
I have a similar servo to this from a plane that I have salvaged parts from. However, 2 of the servo arms were chopped in the factory to fit inside the hull. I can't find any replacements for this! Any chance someone can help me out here?
Thanks for help LasseK! I found the manufacturer specs here www.link and it seems as if it is 4.82mm in diameter and has 20 teeth/splines. It's a PZ-15178 but has hobbyking branding/sticker. Is this enough info? Your help is really appreciated. Thanks!
OK, thanks for the credit! I checked one of my HK15178 servos and its output spline shaft is 4.8mm, and it is a 20 spline shaft. So I would say it's very likely that the HK15178 arms fit your servos. If I were you, I would simply buy a few HK15178, because you will have a hard time finding servo arms much cheaper, and you can view it as getting the servos for free! :-) Also, and on a slightly more serious note, these servos are quite good in my opinion, they might serve you as spares for the ones you have (if the space allows it, as I understand it the HK15178 is a few mm taller than the ones you have, but you might be able to accommodate them). But you will get the servo arms anyway! HTH
Bought 5 pieces, despite this color as the glowing orange. to try. The price is excellent, although the color I disliked.

Just received my servos. I purchased 5 of them and the price including shipping was the same as purchasing 2 Hitec HS-55 feather servos. Comparing these with the HS-55 they weigh in about 2 grams more that the HS-55. The case feels tougher than the HS-55 and I think will be less likely to be crushed when screwed in. I like the orange color and will purchase more in the future. These are great servos for the flat foamies people are creating. I plan on building a flat foamy soon to give these servos a workout. These are also great for small park fliers. Expect more orders once I show these of to my friends at our RC Club.
HobbyKing did great in bringing us these great servos.
