Wow! 1/10 of an ounce! That's great! Let us know how much that increases hover pull out. I'm certain you'll see a noticeable difference.

I wouldn't mention this to others. If you ever start to compete that will give you an advantage that just won't quit.

I use a prop reamer. It's either standard or metric I'm not sure. I use it for all my engines. Some are loose and some are not. Works for me.

Thanks

PS: If the prop is a bit loose on the shaft, wouldn't that save a bit of weight also? Maybe a 1/100th of an ounce. We have to get it where we can.
