Servo saver?

[Cooper]

I think I have to put an end to this thread. I don't think I stated my question to be understood well. My servos are not binding, breaking, being stressed, cheep, expensive, big , small, ect,,, from normal use. Just from high speed wrecks!!! No mistery there folks, things break. Speed is expensive and I'm not complaining about that or from anything. I simply wanted to know if anyone uses servo savers. The "load" is from high speed kart wheels ,flips, wrecks. Not from normal turning. Again no binding in the linkage! Come on guys read the post and question pertaining to the thread. End

Cooper,

One thing I notice was that you have you linkage on the servo at the most outer point on the servo arm... I assume (especially for SAW) you do not use nearly any of that travel. I wonder why you need it at that outer most location. That creates tons more stress/torque on the gears. I would move the linkage all the way in to the inner most position and maybe open up the steering travel adjustment on the radio as again I assume you have it limited way down from 100%. I may be off here, but this might help out the situation a bit.

ps- you have any pics of the back end? Rudder connection?

Cooper,

I'm hangin' with you on this - three reasons : I still would like to see a solution to your sitch; might learn something myself to apply to my tunnels; I've kaboshed some high dollar (they mostly seem to be in that range) low profile servos in my first SAW tunnel 'till I re-engineered for standard sized ones (hint), and I appreciate your engineering creativity which may help me in my future quests to find unique solutions to builds.

There's somewhere in this forum (beeen looking, haven't found yet) a thread I started on servo savers some time ago in which some suggestion for a "strain relieving" cure that's been used by the gas/nitro community has been shown. Involves two shaft collars and some silicone tubing. I'll find it hopefully today. Worth checking out.

Hey chopper thanks, seems like you r getting my questions lol!! I like the tubeing idea, when I run out of low profile servos I will redo the mount and go with horizontal mount, be able to use full size servos.

That is strange... What are you using it in? Pics of linkage setup? Something isn't correct on that hardware I would assume.... weird for sure.

This is one of the few videos I have of a crash, and this was a slow run, have a 8s set up that really make her rip, so this s what causes servo to break. And this crash was fairly simple usually she goes airborne about 10-15 feet..

The problem with the silicon tubing idea is it allows the rudder to oscillate around the neutral position - NOT what you want for SAW runs. That crash is nothing to talk about compared to what myself and others have experienced - slow and gentle by comparison. Tony has the idea, go with a man-sized servo, leave the boyz home.

Just get a better servo. I use low profile servos and don't have any problems, but I only use metal gear servos. I have put a lot of load on my servos wtihout failure, this one is a titanium gear servo. The crash in the vid bent the rudder, but the servo is fine:
