Got a spinner from GP that is a little differant from what I am used to. I have used many smaller nylon backed spinners. But I wanted a 3", and nylon that large I have heard is not as good as aluminum. So, I compromised (Due to my budget), and got a nylon/aluminum backed 3" spinner by Great Planes. Which of you have used them? And are they ok? Is there any inherant problems with this type?

I made the mistake of buying two of these pieces of junk. Unfortunately they were all that was available from the local poor excuse for a hobby shop. There is no knurling on the backplate. They give you a couple pieces of sandpaper to keep the prop from slipping. There is also no way to register the prop cutouts and screw holes in the spinner to the backplate. Other than that the shape was pretty good for a 1/12th scale Ki-61. I wasted my money; I hope you don't.

So, it seems you are unhappy with the design, which does not sound as high quality as tru-turn of course, but what kind of operational problems have you had with this spinner? I have heard some like them and some don't, but don't really know what kind of problems are inherant in this design.
Has anyone had any serious problems? Like melting due to heat from 4 stroke engines? Or being badly out of balance? If so, what is the best technique this particular type can be balanced without a center bolt hole to use on a prop balancer?

I've found that Dave Brown aluminum spinners seem to be pretty good value. Tower Hobbies offers a 3" Dave Brown aluminum spinner for $24.49. Dave Brown part #S230-8230. They also have the 3" Great Planes aluminum spinner for $24.99. I've found that alot of hobby shops will order the part for you, if they don't have it in stock, or don't normally stock it. This way you can save some shipping if all you need is a single part.

I know that the aluminum spinners are the way to go, but being on a budget, and wanting a white spinner to match my plane without having to paint it was one of the isuues, so I have already ordered one, and didn't realize whether or not his brand and type, ie aluminum backed w/nylon cone could have some problems.
Since the thing is already in the mail, I just wanted to know whether or not it was ok to really use this kind, ie safe & reliable, as it was only $7 vs an additional $20 for an aluminum one.
So far, R8893 is unhappy with its design, but no one really seems to have opinion as to whether these spinners are really safe and reliable to use or not.

All:

Du-Bro has very good plastic spinners, always well balanced, and sturdy enough for using an electric starter.

Other plastics range fron "Wouldn't have it on a toy" to acceptable, but I'll stay with the Du-Bro for my plastics.

In metal, I've not seen any that were not OK. I've used the SpinRite from Maxx porducts with good results, but they always are out of balance.

My favorite, of course, is TruTurn. Have several of them also.

But the aluminum backplate with the plastic cone I do not like, not because of weakness or any design fault, I just don't like the looks.

Try spinner nuts. I've phased out all my Dubro spinners with Dubro spinner nuts.

Large plastic spinners 3" or larger CB, Top Flite,] have been a waste of money in my experience, T-F are actually dangerous, spend the money and buy aluminum because: if the prop rotates on the back plate or the starter turns the cone and touches the prop the cone will crack and fly apart, pieces everywhere. Same if the engine backfires. Have learned this the hard way, trying to save a few bucks.
