Actually, sheep driver, the Supermunk (stick a proper Lycoming into your Chippie) makes an excellent glider tow plane. Not at all a ugly hybrid mongrel, it still looks good, flies well, is relatively economical to maintain. Several big gliding clubs rely on the Supermunk.
Pawnees have power, but only one seat. How do you train your tuggie? buy another tow plane for training? Get real!
Big tailwheel Cessnas are scarce in the UK.
