What do we mean by daunting ?
I have flown several types with either high approach speeds or with seeming acres of "bonnet" trying to hide the runway and they presented challenges unless properly current etc.
I suppose they would be daunting but then so would flying a 172 in a challengeing and gusty crosswind.
Flying a 172 can be just as much fun as a J3. Its all about what you do with them, where you go and how you go there.
Really daunting must surely be a small single seater with more power than is needed and with wings so small that the word glide has a vertical definition. Say a Cassutt.
