RE: a good taildragger trainer??
I suggest a 4*60 in kit or ARF version, and as previously mentioned I am tempted to say that an ARF will be cheaper to make airworthy than a kit.
for example here are some stuffs not included in most of the kits.
-weels
-covering
-glues (at least 3 diferent kind)
-a minimum of specific tools
- tank
Of course you will need the glues to complete your ARF, but you may buy it at minimum quantity and save the rest for the next airplane
