Noticed on my last run that the steering servo seems to have become really weak. I changed batteries very recently so I don't think it's the batteries. Is the steering a known week point? What is recomended to fix this?
 
hitec 645 will fix you up.. the steering servos take a beating upgrade to a hi torque one.. i would advise getting a rechargable battery pack soon to.. they give you more voltage therefor stronger servos..
 
ye, definately, the hitec is a good affordable upgrade from stock servo, there are better ones out there if you still have problems. if it's been a sudden change in how it steers, check the pillow balls in your steering, disconnect the turnbuckle from the servo saver and see how easy it turns by hand, if it's stiff or turns and stays itself then there's binding on one of the balls
 
Could also be that you tightened the steering knuckles too tight...
 
I think this weak servo symptom was connected to a rough day with lots of mud....so it could very well be some crap stuck somewhere.

I took it off the servo and tried to turn it by hand. It's ok i guess...not sure how it's supposed to be. Cleaned up as much as I could. Drove it again and it still seems weak so I must have busted the servo somehow.

Thanks for the tips. I guess I'm going to the LHS to buy a Hitec 645 today. How much do they cost?
 
if your going to be doing a lot of mudding might i suggest plasty dipping your new servo so that this doesn't happen again.. there is a how to on here somewere.. but basicaly you dip your servo in plasty dip.. (available at most hardware stores) then trim the screw area so it will move again.. this will keep dirt and water from getting in.. I've also heard of people just "painting" the plasty dip around the seam of the servo.. it would make it last longer in wet or muddy conditions..
 
Heck, it is even good for dusty conditions... I heard on some other forum that plasti-dip can make your servos overheat because they can't breath... is this true or a bunch of :horsecrap:
 
could happen.. i think thats why some people just do the seam instead of the whole thing.. i dont think it would fry it but it may run hotter.. just keep the coating to a minimum..
 
If heat is a problem then get some old heat sinks for CPUs and thermal compound from Radio shack...leave the fins open to the air when you seal the servo.....simple fix to the heat problem....
