That's a great question! It's one I've been waiting for. Pardon the long reply, because I have a bunch of points teed up. It's not Utility Class. It's also not Normal, Restricted, Aerobatic or any other class. The Piper J-3C is certified under CAR 4 before those classes were a thing. The TCDS if I recall is A691. If someone has a PA-12 or PA-18 then these would be a no-no. That said there are maneuvers I won't do in the J-3. Negative G and snap-maneuvers, for example. Negative G are tough on the motor. Snaps are hard on the empennage. I also increase the maintenance interval on attach hardware, etc. The Cub makes primary aerobatics accessible on a tight budget, and I think that does a lot to improve our collective airmanship when access even to Citabrias let alone Pitts may be prohibitively costly. That said people CAN get the wrong ideas from these videos and start looping their 172s and Cherokees. I'm NOT about to support that nonsense. On the balance of things I think we, collectively, suffer more from atrophy in our airmanship than we do from pushing too hard. That said we can't talk about exploring an airplane's envelope without discussing practical and legal limitations around us. Great question! Keep 'em coming!
Thanks. Was up yesterday in a cub doing some laps around the patch. Good stuff.
I love the illustrations!
Thank you! It's an excuse to doodle on my phone.
Very nice! Miss flying the J3.
Thanks! 👍
Van Halen plane rocks!
Any concern that you’re doing aerobatics in a Utility Class Airplane?

Very nicely done…… Please wear a parachute
