Savox SC1257 Failure

[Dark Stranger]

I am running a £26 cheap 12kg savox on my throttle and brake and it is coping admirably. Only issue I had was setting the failsafe to max brake and then forgetting to turn the car off, doh. That killed the first one, but since centering the failsafe to neutral, the servo has been faultless. I use a 20kg on the steering that has been used through a wet winter series, so far so good.
I returned one 20kg servo because it lost strength when it got warm, replaced by CML no probs.
I had a hi tec that lasted 2 days and various others. Ive seen loads of aces fail too. There is no perfect servo, but CML service on savox is spot on, so I'd rather use something that I know will be backed up, that risking my cash elsewhere.

I can't help thinking that there is an issue with ya car though fella, seems very strange for you to kill 2 so easily.

I thought there might be an issue but I have eliminated every outside influence that could be responsible. End points, stiff throttle linkage, water ingress etc.

I would expect the steering to suffer before the throttle. The steering servo has been faultless but this will be my third throttle servo in 3 hours of use.

It is possible that the T/B servo is touching the chassis on hard landings. The Steering servo is laid flat but the throttle servo is upright. Try spacing the servo up slightly to make sure you have got a couple of mm gap to the chassis.

I have used the rubber grommets that come with the servo. There is several mm gap between the chassis and the base of the servo. It's never even been used in anger, just on flat grass.

I assume you aren't running Lipo.

I assume you aren't running Lipo.

Yes I am but it is regulated down to 6v.

Yes I am but it is regulated down to 6v.

That could be your problem????

I know that in theory it should all blow if the reg fails, but theory and practice are often different.

I wanted to go Lipo, but looked at the cost should the reg go and decided that I'll go to life if I move away from NiMh.

[Dark Stranger]

Reg is working fine fella. Nice constant 6V.

I had a savox go in feburary after only a single round which was replaced in march by BMM, this servo has also just gone after the NRS round up at CSOR this weekend so only done 5 races.
Presumably im still covered under the warrenty from the start date of the original servo?

are you really sure your servo is not under pressure at full throttle as if is then slightest chassis flex will strain servo badly leave couple of mm free play and try again

Throttle end point is set to just about fully open carb barrel (68%). Brakes are set so they engage fully but don't stress the servo too much (39%).

CML simply replied to my email stating 'send it back and we will send you another by return post.' I sent it back via Special Delivery today so will hopefully have another new one in a couple of days.
