I own a RB S7 standard plug which I use a RB#6 plug in and im using the same plug that it was broke in on and I have been thru 1 1/2 gallons so far and can not complain at all and not changer a plug!! I have had people tell me that motor screams im also using a JP3 pipe. And im getting 8 1/2-9min on a tank and temps running 220 or so, and this is not a modded motor either!! But the one thing I will say that my LHS can not get parts for them or at least plugs, I know the RB#6 plug at amainhobbies.com have been on back order along with alot of other hobby shops and the only place i have found them was towerhobbies.com.

I don't think I will own a diffrent motor for a while, But i have been looking on Ebay for a turbo head for tunnning reasons I have heard they are a little eiser to tune...
