FNG, The funny thing is that there shouldn't be anything different between rolling a 172 onto the runway and rolling a Citabria on. Just that the 172 will be on the nosewheel once it slows down enough. The attitude at touchdown should be a full stall, right. In a perfect world anyone who can land a 172 perfectly should be able to do the same in the Citabria... Let me know if I'm missing something here.
On flying, the Citabria is quite light and significantly more powerful than a 172, so that helps the fun aspect. It is probably impractical for schools that don't have hangars as it is fabric covered, and I guess that requires a bunch more TLC than a metal skinned aircraft.
Hopefully, some aerobatics are lurking in the not too-distant future...
