Cool, I have been running the WS7 crank in my Hobby 9 for about a month now. The crank was fairly new, I bought it for my modded S7 I have.

what kind of runtime you getting with that killer 9, it looks like it has plenty of power but im curious what the runtime is on it.
Hello gofast,
I am getting 10-11 mins with 25% Byrons Pro fuel, 7mm restrictor, and exhaust cooler. Engine is so smooth and the power is there when you need it.
I'm planning on getting another one very soon and sending it out to
ABmods for stage 2 modification.
