Doing aero's in any a/c is a joy. It's just that some are even better than others.
Personally I was lucky enough to start my aero training in CAP 10's. I still feel that they are the best machine available for beginners.. .Unfortunately those heady days have gone and I now teach (occasionally) on a 150 aerobat. To be honest I think they are terrible to learn on, take ages to climb after mistakes, viz is poor and doing aeros with a control column is definately not as fun as with a 'stick of joy.'
I'm lucky enough to get the chance of flying Extra 300's, Van's and Yak 52's on occasion, and I feel that something like 300 is a bit much when you first start chucking things about. Something like a Cap or firefly is really ideal to start with. They are a little bit exotic and are strong enough to allow the student to feel that little bit more comfortable and that always leads to better progress.
Wobbly prop or no wobbly prop. Hmmm, Learning to keep an eye on RPM's etc is a good thing to get in the habit of straight away. Having a wobbly prop does make life easier, but it can mask problems, and if you decide to try aero's without one..... We've all done it. Over-revving is not funny and really cuts down on the fun factor.
Give Gennady a try, he really is something special and the yak is alot of fun.. .If funds allow, try all the a/c mentioned by everyone if you can. Make up your own mind what you want out of aero's. Competition or just fun??
But, please don't try to run before you can walk. Start small and build up, in the long term you'll find the standard of your flying will be better than if you just jumped into the latest "hotship". .Most of all enjoy. It really is the most fun you can have. In Bed OR out!! <img src="wink.gif" border="0">
