Definitely get with a competent instructor just like you did with full size aircraft. Every time you advanced in full size, instrument, commercial, multi you had an instructor. Working as a mechanic, you were required by FAA to receive OJT, DO NOT break the cycle now. You MIGHT get lucky, but odds are in favor of you ordering a new kit within the hour of your first flight. I speak as a full scale pilot. a/c mechanic, and R/c instructor. PLEASE listen. It won't slow you down that much and will in fact most likely hasten your learning curve. And being a club member will give you some new friends full of advice, good and bad. Some just full of it, if you know what I mean.
Enjoy your flying,
Bruce
