Can anyone suggest there is a better trainer than a C152?
If anything puts you off in the early stages it will be a Citabria - twitchy, nasty unforgiving little things..
BTW what does a tail wheel actually teach you other than you must keep it straight, be well on top of it if looks like going at all sideways and how to land in a three point attitude? You can fly a C152 really neatly too - it just wont punish you as badly if you get it slightly wrong during your early stages, which you will.
