Hextronik HXT500

Application(s): Park flyers below 500g AUW

Comments: These are not bad servos for the price, but unlike the larger HXT900s, they do strip gears regularly. Over time all the HXT500s that I have installed in larger planes have stripped their gears...and all in exactly the same way. Interestingly, the gears do not fail from too large a force being applied to the control surface in flight or the control surface getting deflected in a crash, but rather when the whole airframe is 'jolted' in a hard landing and that sudden 'shock' (possibly transmitted through the control surface)seems to make short work of the gears.

Application(s): robotics

Comments: this small piece really surprised me. for its nifty price i thought it would have been a failed purchase, but it's been great working with it. :]

Application(s): small flying wing

Comments: Excellent on my mini swift!

Application(s): Aileron in Alula Evo

Comments: robust cheap and reliable servo.
Even runs on single cell lipo in my alula SAL.
(Centering is generally ok but maybe not perfect for this application.)

Application(s): Foamies tail feathers and aeleron

Comments: Great for park flyejrs and foamies...
On more expencive planes I use hitech 45hb

Application(s): small planes or delta

Comments: used this servos all the summer whitout problems;
last week i fly by low temperature around 0 ° celcius and servos worked , stopped , worked .... and i crashed !!
did some one have same bad experiences in winter ??

Application(s): Indoor scratch built foamies

Comments: Nice not to have to consider the servos as a major part of your investment. These are excellent servos and really cheap.Buy 'em by the handful!

Application(s): Park jet and indoor foamy

Comments: This is *the* standard servo for foamy park flyer scratch builders. Look anywhere on RCGroups, Wattflyer, RCUniverse, etc. You'll see this servo all over the world and in every conceivable aircraft.

I have used dozens of these servos, have installed them on lots of planes built for others, and have recommended them to everybody I know scratch building planes. The only ones that have failed have been driven into the ground under power or destroyed through other violent abuse. At three bucks fifty apiece you can afford to build a lot more planes.

I would also like to mention that the actual measured weight of the servo with its cable and connector is 6.4 grams, not the 4.8 listed by the OEM. (Confirmed on two different digital scales.)
