RE: can the Kellett loop?
Chris,
Having built a few of them and flying a few more I would say that it might loop.. I would not want to loop or roll one.. The full flying stab is not very stong for Aerobactics..
The only person I know that is doing any aerobactics is Joel in MT. but he has a highly modifyed PT - 25 and an enlarged Whistler..
The Kellet only has rudder and flying stab.
Good luck,
Jim
