If you have access to a local track and local racer's who will help you out....Buying BIGand buying ONCEis THEonly way to go,..,....i cant count how many new guys start out with RTRjunk to only have Pro gear within the next month or 2 as they saw what the REALrigs were capable of compared to the RTRstuff they Thought was the same....fortunaly you get what you pay for in this industry.
Buy Big and Buy once is my modow for N00bs....ESPECIALLYwhen it comes to servo's.
