Hey Larry;
I have a memory of you looking for Tornado 5-3 three blade props for a 1/2A stunter. Might have been a while ago, and you had just broken your last one?? I just acquired some Master Airscrew 5X3 three blades of the latest generation and they look pretty nice!! You might want to give these a look. They are available in left and right hand rotation also. I got a few but have yet to try one, may put on on a Cox Viper with hopped up engine to try it out. Let me know what you think.
Type at you later,
Dan McEntee
