What I don't understand is why doesn't someone step up and make a simple spinner that doesn't need grinding out for the wider props. I know I've read a lot of posts here where people were wanting to know how they should, or if they could, cut the spinner so the prop would fit. All you hear on here and at my club is how great apc props are but you can't find a simple spinner to fit the d**n thing. You have to spend 45.00 at tru-turn or get one by great planes only to find there isn't an adapter for it (not for saito anyway). I KNOW people would buy one if they were made.
