It's always amusing to see the negative remarks from people who haven't even bothered TRYING the product....

Both are basically manufactured by ''Hextronics'' ( AKA Tower Pro ) which is the trade name for Hobby King's hardware.
The HK 15288A is a metal geared variant.
I've purchased over a dozen of the latter and have found no problems to speak of.... however bare in mind that low end metal geared servos do have higher wear rates.
Normally plastic ''gives'', producing less overall wear... and this is one reason many metal gear servos go to more exotic metals to reduce wear... but that brings up the price greatly. These servos do NOT use Titanium gears or the like.
So they may not last as long as the 5010's, but you are still talking about decently long lifetimes in all likelhood they will outlast your plane.
Otherwise they are little different than the other HX analog servos.
Sorry about that, it is not that I haven't bothered to try them, I just that I haven't tried those particular servos.
I have had some bad experience with hobbyking and HX servos before, so I'm a little biased and have never understood why one would get stuff from HK when there are so many better products out there.
I do promise that I will try to not say anything the next time that HX servos pop up here, and I'm sorry if I have offended any dedicated HK fans out there.
