### High Performance Spinners Thread ###

Hi, dont know what you think, but I having a hard time finding spinners that are good for high performance, both for folding AND normal props.

I was thinking of making this a thread which all can say which spinners they like, and what sizes there are to buy, both outerdiameter of spinner and for which shaft they are availible.

You can also write down your thoughts of the spinners, maybee you have tested it, how many rpms and so on...

It is also ok to write down which spinners to avoid..

I will write down all my experiance as soon as I come home, be free to write down what you like..

For exemple Im having hard time finding a good folding spinner 30mm for 5mm shaft, that can take power and rpm good..

For fixed props I've been using the Tru-Turn 30mm spinners, I've had good luck with them for a few years now.

+1 to the spinners Rolf linked. They are seriously awesome. Very well balanced and secure on the shaft.

I like the mpjet 30mm spinners for small fixed props. (4-5")

Some guys here have had some bad luck with Tru-turn... I have one under my desk that is rusting away!

Rold, and sykotic, how does these spinners on picture take higher rpm ?

I have few of them, but was worried about the platstic top is not fixed at root, so maybee ut will start flex at higher rpm?

I have spun one at 50k rpm (without a prop) in my hand (lets not talk about safety right now..) and it didn't appear to have any vibration or problems.

The plastic is pretty thick, and it is only the last few MM that are not supported, at least on the ones I have (29, 34, 40mm).

I have used those spinners from aircraft world that you linked as well Sebbe, they are great.

ok, maybee those spinners are the one we are after then.. 50 k is damn good.. yes the plastic is pretty thick..

I have only one problem with mine, its the spinnerkappe is not really good fasten with those 2 screws, seems the plastic wears out quick when screw/unscrew, making the spinnerkappe able to move sideways, not good... I will order a few spinnerkappe more and try to get new slightly bigger screws....

ofcourse you should not screw/unscrew it to many times

But if you can move the top sideways, makes me wunder if the screws are tiny to small in diamater, hmmm ? Guess i have to measure them, to see if thats the problem..

Good finding thow..

I've just bought a HM spinner, very nice IMO, I really like the clamp fitting over the RFM's grub screws, but I like the cool nose of the RFM.

Rolf told me the HM's have no RPM limit, I thought RFM told me the same, but I've got a figure of 60000rpm in my head from somewhere, so maybe that was the limit? I've deleted the email now so you'd have to double check if you needed to.

MP Jet do an aluminium cool nose spinner which I found well balanced and uses a traditional collet fixing. The cone is only epoxied on to the centre piece though.

The 30 mm Hyper spinners from Vladimir are quote 'I think Hyper Spiner 30/x/3 will be ok to 500 W motor.' Maybe not typically high performance at 500w, but considering my Voodoo is currently only about 270w on 2s using DUP's 4.7 x 6.1 folder I think they'd be ok on a small high performance model. The reason I was interested in this spinner is they do a 3 degree twisted yoke on the 30mm, it would up the pitch of the folder to nearly 7", I'm pretty sure the motor will be ok but not sure if it'll ever really get going on the Voodoo due to doing smaller circuits. Or it would up the pitch on the GM folders a little too, on the 5" it would take it to 5.72", not sure about the 4.75 GM tho, might take to a touch over 5" I think.

Those are MPJet spinners

RFM make a 30mm 5mm spinner, you wont break the centre peice, it is possible to pop the cone off though if you knock em http://www.soaringusa.com/product.ph...&cat=58&page=1

So far the best for 30mm 5mm shaft foldings are RFM or HM spinners...both have grubscrews, I would like to find one with a collet
If anyone finds another one in this dimension, please YELL !!

I have some idea, but will post it later if I descide to try it, its a combination of yoke and spinner from different brands, need some dremel and balancing to make that heppened thow..
