I've had these in an AXN for sometime now, no problems! One of the better servos I've had in its class.

Read about some servos drawing high current and causing brownouts... I plan to use these in my bix 3... 4 total (no flaps) Would a 2 amp bec be good? Or what would you suggest?
 NickS 19 points
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. Nick

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?

Can you measure the diameter of the servo arm shaft on the servo (the diameter of the spline shaft) and also count the number of splines?
 Andrew 13 points
Thanks for help LasseK! I found the manufacturer specs here 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!
 LasseK 1706 points
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

12 days from order to receipt and I paid the cheapest/slowest shipping, air mail non registered which was $2.99 shipping.

Received 4 of these and tested them all out.

You know what?
darn nice servos that come out to $2.64 each with shipping!

Each one was spot on 10g just as advertised.

The bag with the horns and screws weighed in at a wopping 2g and half of that was the bag.

Hooked them up to a little park futaba fasst receiver and ran these from a 5cell Nimh pack, so 6.6v for testing.

Ran the servo movement test and then the neutral test.

smooth, fast and centered perfectly well.
All four operate as smooth and quick.
Oh and each one responded to single clicks of trim.

The wire with the plug is 7 1/2 inches long and the wire seems to be very soft/flexible silicon.

If you are looking for inexpensive servo's for your foamy or small park flyer, I'd use these.

Next, I'll take one apart and have a look under the hood

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.
