For the last time, there is not need for a 9XL. 4S on a 7XL will run great, and cool if geared right. A 9XL on 4S isn't that fast, at all.
Stick with the 7XL and simply take the spring out of the clutch setup. One thing you might want to do though is get a RC-M heatsink/clamp to keep it from popping.
