Hey all, I'm new here and have a question of course. I just got a used muggy and some brand new steering servos (jr z590m) got it all together and it doesn't turn as far left as it does right. I visually looked at suspension components and they look good. i unhook the servos and freely the wheels turn about the same. any tips or tricks i need to know about? could it be the radio? thanks for any help

Radio end points and trim is probably off.

What's your radio? If it was used, the previous owner probably has the trims set to something other than 0 and more than likely doesn't have the left/right EPA's set the same. That is, if it's a radio that has those settings.

Well, that radio has trims and EPA. EPA's are nice as they let you set how far left and how far right really goes. Use them to make the linkage almost go to full lock in both directions, then use the trim to adjust your center if needed.

If you have your trims set at 0 and then adjust your linkage so everything is eyeballed to center, then you can adjust your trims when running it to get center to track correctly, but usually you can adjust EPA's when it's on your bench. Just make sure to not set the EPA to having the servo pushing the linkage so far in either direction that it his reaching it's mechanical lock, or you will be putting excess stress on the servo(s) and draining your receiver pack faster than necessary. With digital servos, they will actually fry themselves if you have the EPA's setup to go too far.

Found it in your manual, page 11. Well, really page 18 of the PDF:

I had the older JR XR2 many years ago when I got my first RC. Losi seems to have a tendency to include decent electronics in their RTR's.

Anytime you get a new radio, you have to adjust the EPA's and trims to suit the vehicle. If need be, reset yours, then align everything the best you can with the radio at 0, then tweak the settings once you eyeball the linkage.
