MA-020VE Steering Never Returns to Same Centre Position
I suspect a faulty servo saver, or poorly assembled servo saver. When steering left and returning to centre the centre position is more to the left. When steering right and returning to centre the steering position is more the right. It's been like this since new, never crashed (yet).
Any ideas?
Overall I'm pretty disappointed with the quality of assembly of my MA-020VE Pro SP. Bad solder joints, over tightened screws, screws threaded in off axis, wires crushed due to improper assembly, etc. The list keeps going.
Is this common with Mini-Zs nowadays? I bought mine out of HK from RC Mart, hope I didn't get a "hacked together" off the assembly line "counterfeit".
I have purchased (all new) 2 MR-01s, an MR-03, and an MA-020S and none have ever had such poor build quality, if fact, they have all been perfect. The MA-020VE Pro SP is the only one I purchased out of Hong Kong. The others from North America and Japan.
My servo issues on the mini-z pro's I own (2 x MR03 and 1 x MA02) had to do with either a stripped gear within the servo (get ready for some interesting surgery) or with a piece of tire rubber debris getting lodged within the servo gears (still have to take it apart).
I can definitely recommend the metal 4th gear upgrade for the servo. I have installed the metal one made by Kyosho and the aluminum one made by PN in my MR03's. I don't notice any difference between the two.
I've always had good luck with rc mart; same with tiny rc (associated with this site).
I've had this issue both with 010 and 020 and it directly related to an excess of material on the servo cover. The servo arm ever so slightly rubs so my suggestion is to dremel the inside of the cover a bit to give the servo a bit more room.
You might also check the tie rod throw for binding.... I've had that as well.

Another thing that has worked for me is not to totally tighten the four countersunk screws that hold the lower suspension arm/diff cover. Also adding a little bit of ruby lube to the tie rod helped too. The servo is a crazy tight fit in the AWD chassis and it can rub if things are even the tiniest bit out of alignment.
