Smiles Posted November 30, 2009 Share Posted November 30, 2009 Hi Guys ,I need to order a spinner for my JP Cub trainer but i am unsure which one to buy.The JP plastic ones come with two front screws and look like they fix onto the prop are these any good or is it better to spend a bit more and get one with an alloy back plate?. Regards Smiles. Quote Link to comment Share on other sites More sharing options...
Colin Hostler Posted December 1, 2009 Share Posted December 1, 2009 Hi, the alloy backplate is more rigid and in my opinion a better buy but either will do the same job.What you must know is that you will need less clearence (between the cowl and front of engine hub) for the alloy backplate type because it sits directly on the propdriver whereas the cheaper all plastic type overlaps back over the propdriver.I`m sorry if that doesn`t make sense. If you can`t understand I`ll try and put it another way. Colin. Quote Link to comment Share on other sites More sharing options...
Garry Pollard Posted December 1, 2009 Share Posted December 1, 2009 I always use the spinner with the alloy backplate, as in my opinion they are much better balanced. Yes they are dearer, but you get what you pay for. Colin I think your explanation was easy to read and understand Garry Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted December 1, 2009 Share Posted December 1, 2009 Yes, the Irvine are great. I am always sorry that the GOldberg spinners are not made any more. No screws, just fit the backplate behind the prop and three or four pins on the cone pop into the backplate. I have stock of these and buy any that I can find.

Ernie Posted December 4, 2009 Share Posted December 4, 2009 Hi Smiles, I would use an all alloy spinner. You can get a huge range from just engines, including a lovely three bladed job they fix to a threaded extension to the front of the crankshaft.. You have to tell them which engine you have, so that the thread is correct. The alloy ones are generally of better quality, they are well balanced, and keep their good looks, also they don't get damaged by an electric starter ernie Quote Link to comment Share on other sites More sharing options...
