Ok, someone else hare has to be having problems with these also !

it is not my 3rd HS-5245 that has failed. It stops centering corectly, and jitters allover the place, and finally it dies ..


anyone else here with problems with this servo ?

I know its an old thread, but it's still an issue. Ive had 3 fail... this time im sending it in.

Be curious to see how this pans out as I just installed one of the 5245's on a UP-6 brake valve after having a HS-225 analog servo burn out.

ive had 2 225mgs fail too, and 3 others that are still in service too.......... goodluck

For a second, I thought Voy was back...

I have used HS-225 on several applications and have had a number of them fail. I have stopped using them and am reluctant to try the HS-5245 because I understand that it's the digital version of the HS-225. By the way a friend recently told me that he had read that the HS-225's don't like 6 volt packs and will eventually burn out on them. Perhaps that was my problem since I use 6 volt packs on all my planes.

Same here raf. just buy JR Joe C!!

The HS225 and 5425 is an abomination of a servo and one of the very few lemons that Hitec has made.

In trying to cram the torque and speed of a standard servo into a mini package they've sacrificed the strength of the gearset and the longevity of the motor and feedback pot.

If you search RCU's archives you'll find many, many instances of HS225 failures, ranging from broken gears (even in the MG version), burned out amps, lousy centering due to worn pots and a number of other issues.

The 5425 is just a digital version that shares the same gears, pots and motor as the 225 so the same problems plague it.

I wish Hitec would stop marketing it as "the mighty mini-servo" and effectively convincing people it's a suitable lightweight/small-sized replacement for a standard servo in most applications it's not.

The only people who seem to have had any real success with these servos are those who use them on very fast models that have tiny control surfaces with minimal throws. Due to the mechanical advantage such a setup allows, the servos are barely stressed in such a setup so tend to work modestly well. Try to use the quoted torque figures however, and you take a *big* risk of breaking gears, burning out amps and wearing out feedback pots.

Hitec make some really good servos this is not one of them.

Wow, I guess I should take them (HS225MG) out of my Roo's and HotSpot's Rudders. I have over a thousand flights on the these jets and never had a problem. I didn't know I was doing anything wrong! [X(].

we never had problem with HITEC SERVOS, ( mini and sport size ), we use a long time ago in JETS.
I like the TITANIUM GEAR HS-5955, I use in our ELAN, and perfect.
We had problem with some JR mini in 2005, and HOBBICO mini too.
