Ok,, you got the FI pumped version. Makes a big differance. Although,, I've heard even those can act just as Richard discribed.
It's not much fun deadsticking a warbird over and over.
Check with the RCU two-stroke crew and ask them if you'll need a check valve to keep from flooding. I used a Perry pump and all it did was make the flooding worse until I put a check valve between the carb and tank.
