One last thing, the .21 Zippkit launch. My .21 HAD a problem with the launch. To run the larger props that you need ( the launch ) has to be right. Joe Petro gave everyone a lesson in proper Zippkkit .21 launch. I wish I took a video. You need to get your boots on & launch Hard & parallel to the water. HARD did I mention SWIFT I think swift is a better term. Wing it like a Frisbee. don't be shy. We also found fuel coming out the case /head-button, a file & wet & dry sandpaper on a flat surface . There is a small lip. I sent a pm to Glenn I am doing the right way. Keep all fillings away from the inside. Here is my reworked head.I had a ear plug in the center. I washed out all metal.with auto carb cleaner.
