Dubro makes a nice metal one in several colors for the TD and Norvel.
The best ones were made by ACE in 1.2 and 1.5 in white nylon. If you can find any in an older shop grab them as they were light and really worked nice.
another item is the old C*x rubber spinner that they used on some of their ARF's look around for then .
The market is really ready for some nice small spinners again.
Oh don't drill that hole in the TD that was for timed pressure, it will really make you needle valve incredabily sensitive and you will need a pressurized tank system to run the motor.
If you want to presurize the thing use a pressurized backplate.
