Hi, I've just put my freshly built M05 Pro V2 on the (carpet) track for the first time, and it's a blast !
I had 2 main problems :
- there was no way to keep the car straight on the straight. It would either go left or right but not straight ahead.
- the rear was breaking out a lot. I could make some nice corners, and suddenly it would spin out. I made a lot of nice 180's, a couple of 360's and a few nice 720's. Looked spectacular, but wasn't my intention.
The steering problem was two-fold; the servo saver somehow had some slack in it so it was possible to move the steering arm a little bit while the servo didn't move, and one of the plastic arms in the steering linkage didn't rotate freely around the screw but needed some force to be rotated.
I put on a 3racing servo saver that was available at the track which fixed the servosaver-slop, and I used a body reamer to *slightly* widen the hole in the plastic steering arm so it could rotate freely.
This made the car steer / center perfectly and suddenly going straight on the straight end wasn't a problem anymore. Yay !
But now for the rear breaking out. As mentioned, I'm running on carpet.
I'm using Sweep 33 tires all around.
5mm ride height.
Blue springs in front, 40wt shock oil.
Yellow springs in rear, 35wt shock oil.
Stock diff with anti-wear grease.
As this was my first time on the track, I didn't have / use any traction compound.
I don't know if the rear breaking out (excessively) would be solved just by traction compound (I don't think so though), or needs some more car-tuning.
Any advice (or pointers to advice / links / related pagenumbers in this thread) on getting my car to behave better would be much appreciated!
(Apologies if this has been answered tons of times before but I used both RCTech search function and all my Google-Fu to no avail - I'm not sure what keywords I should be using)
