Heres one for you guys...
I've had my Revolt out 3 times this year and have had steering issues each time, where the rudder will not return to center once I complete a turn. When I noticed it the first time, i brought the boat in and inspected the rudder linkage, and sure enough, the ball stud and link at the servo end of the linkage were 'sticky' and didn't move smoothly. Ah hah!!! I thought I found my issue, so I replaced the ball stud and ball cup with some parts from the RC car parts collection. Now it works smooth as silk with no free-play or slop. I thought I had the problem fixed and went back to the pond....but the problem persists!:doh:
At this point I figured the servo had given up. No big deal, a ball bearing Futaba servo would be a nice upgrade anyway. So I go to the LHS and buy a new servo, install it, and went to the pond. I figured my troubles were over...no sir! The boat still behaves EXACTLY like it did the first time out this season.:doh:
The part that sucks is that I CANNOT recreate the problem on the bench, even while firmly holding the rudder to put a load on the servo. So last night I picked up a new Tactic receiver, believing that the receiver is not supplying adequate voltage to the servo to do its job properly. Hopefully this fixes the issue (haven't had time to install it yet). I will let you all know if this is the issue or not. If the new Rx doesn't fix the problem, I want to convert my rock crawler from 27Mhz to 2.4 Ghz anyway.
If this fails to fix the problem, whats the next step? ESC? I hope not:doh:
