Yes an older thread, but wanted to ask the 501X guys.....(I asked similar question about the 511X....so probably the same racers).
If I were starting out with a box stock 501X WCE.....what are the robustness upgrades needed before I build her up?
What problems are signature with the 501X WCE and need to be addressed?
Thanks in advance for any information.
