Savox 1251 issues - no or little right turn

[simonrhart]

Anyone else seen issues with the Savox 1251 - the low profile servo? I have only had mine for a few months and now I'm finding sometimes that the servo doesn't respond to a right turn. After looking at the servo when trying to turn right, it appears that something is blocking it, when in fact there is nothing blocking it.

Another thing I noticed is, when it does respond to a right turn, if I hold the wheels there is almost no torque in the servo, in other words just lightly holding the servo will stop it from turning right. However the left turn is fine. Weird.

Could be knackered gears I guess.

I have bought another servo for my Kyosho Lazer also a slim line and will be trying the Futaba BLS551 to see if that servo is any better.

I had the same problem.
If you open it up and expect it, you will find the big gear has damaged teeth.

What I did was dremmel the stop notch off and turn the gear around.
Of course you can just buy a new gear set.

Thanks for the insight.

I will open her up tonight.

I'm running this in a Losi 22 on mostly a bumpy track without a servo saver, so I suspect damage has been caused due to this.

Sounds familiar, I'v gone through three savox low profile servos in three meetings.

A mixture of broken gears and where one gear is inserted into another they seem to spin on there own, I think Connor also had this problem.

Ironically the first one I bought lasted me over a year and since then they've managed only a couple of five minute races. Quality control must have changed for the worse!!!

I've opened it up and the gears look fine so do not know what's up with it. This and listening to others has put me off Savox. Will now switch to Futaba as they seem to be a better quality servo.

if the gears look fine they my still be the culprit, as JCB has said in his post,I had to rebuild our savox 1251 in the losi, connor was experiencing much the same problem as you have, when I dismantled the servo the gear all looked like new, I was puzzled and also though bugger, new servo time but then I had a realy good look at the gears noticing how the smaller part of the gear is pressed into the larger gear, so grabed some pliers and carefully but firmly tested each gear...bingo one of the gears would turn inside the other! it looked no different to the new one I replaced it with, there is realy no visual sign of the problem.it will also will appear to work normally when not under load aslo will not make nasty noises like a servo normally does when the gears have gone as there is no gear with teeth missing.

If its not this then it could be somthing deeper like the servo loosing centre pionts etc
