Been towed by Bird Dog, SuperCub, Wilga, Citabria 200Hp. and Pawnee (235 and 260). Behind a Pawnee is like being in a slingshot and yes, it goes up and down quick
We seem to have a considerable number of people who fail to lock spoilers before takeoff and it once took me a while to realise the spoilers had popped after a bounce on takeoff
No problem behind a Pawnee
