I have been noticing something continuously wrong with my XMOD. The turning radius to the left is smaller than the turning radius to the right. I have tried everything to fix this from remounting the servo horn (

http://www.tinyrc.com/forums/showthr...ring+mod+works). The increased steering mod does work wonders. One problem with AWD is that you must reduce the amount of steering using the ST. RANGE control dial on the controller to keep the universal joints from binding up when the wheels are turned too much. After all of this the left and right turning radi were still unequal. What the heck? I figured out the problem is independent of the servo or the servo controller. The only thing left is the steering signal coming from the handheld remote controller. Sure enough, there is a small flaw in the controller causing this. There are stops built into the steering hub (the thing that looks like a tire and rim). These stops allow the steering hub to be turned to the left the full amount, yet the stop when going to the right prematurely ends the travel. There is still more command travel left in the controller, yet the arched groove does not extend far enough to the right thus stopping it too early. The fix is to just use a Dremel or X-Acto to remove material on the right hand side of the tab on the backside of the steering hub. This will allow full available right turn command to be sent to the XMOD's receiver. Well I hope that this helps everyone. Have Fun.
