Plenty and most particularly in the training environment and since this is the beginners forum its an appropriate place. Virtually every new trainer we see show up on a daily basis will have a plastic spinner and probably for two reasons: they are pretty when new and they are cheap.

There are three reasons not to use them:
1. They can be dangerous when improperly installed which is usually the case almost every time. I and many others have been hit by flying plastic shrapnel countless times from other peoples aircraft many times at huge distances. This is the usual result of hurried installation.

2. Spinners are a prime reason for lost flight training time. Improperly installed spinners or just a nicked prop that needs replacing (This is flight training after all) takes up a considerable time and the usual result is you will end missing out on flight time in a busy environment . I will always go on to the next student if time is consumed fooling with spinners.

3. This one is easy with out fail they always turn 'Butt Ugly' with that ring in a short time and you can buy all the different compounds or be as carefull as you can, no never mind - Butt Ugly!


The smart flyer and student will use Spinner Nuts (and thats is the proper terminology Spaceclam) every time and you know they look 'Dame Good'.
