I've built up a completely stock (besides bearings) m05 as a basher/toy. However I have a problem with the steering returning to centre after a corner. It will pull slightly left if I have just cornered left and pull slightly right if I have cornered right. I have swapped the servo out for a good one from my race mini and still have the same problem.
Is this a common issue for standard m05's?
What could be causing the problem?
Yes, this is common for all M05's. The stock shocks and steering are garbage!
Here is what I did to get the steering dialed in:
1) Cut down your end point turning (left and right) to 85% (it may be slightly different for you)
2) replace the stock front axles w/ something like this:

3) use this servo saver:

4) replace the stock steering linkage w/ one of the aluminum setups, -I went w/ the Tamiya brand to keep w/ TCS rules ...yet the 3Racing versions are much cheaper and work just as well (i am told).

For me that did the trick.
Doing those things you've basically replaced the entire steering from servo to wheel. I felt the same frustration when I first got my M05, it would not stay straight and I felt like I was struggling w/ the car. That was my first upgrade. If you don't want to spend that much, you can start w/ the servo saver I suggested. I suspect most of the problem is w/ the stock servo saver as there is a ton of slop w/ the stock setup in this area. The other thing I found was that the stock wheel axles were locking up a bit when I turned the car hard. Switching to a "swing axle" and reducing my end point a bit removed this completely.
