Do what the others have suggested and put a small length of fuel tubing AND A WASHER between the collar and the hub. The washer is needed because the tubing, believe it or not, will cut into the hub and destroy the wheel.

This will not interfere with takeoff or landing and your plane will slow quickly on touch-down. It a;so helps avoid the 'unintentional take-off when you have too much gorundspeed on rollout.

Good Luck!!
