Your blades maybe desiged for 2000 max you're pushing it at 2000. Why on earth would you run a head speed like that anyway? For one thng your poor little engine will run HOT and you will wear out everything a lot faster, that's one reason why most people run between 17500 and 1800 for 3-D!

"Sorry but your information is false" It not a matter of being false, please note I said " you CAN run a higher headspeed but it's not safe. "
