Listen to what rcken said and go by it!!!!! I would also suggest that you go to a field where they fly nitro and just WATCH & LISTEN, then see if someone there will assist you, even if only for advice but better yet on a buddy box at least for a couple flights.
Nitro IS different from elec. and there isn't any reason to screw up because of EGO or any other reason ( stupidity ). Remember " the only stupid question is the one YOU don't ask " ENJOY !!! RED
