I'm sure I've seen threads on this before but I can only find threads relating to initial pilot training on permit to fly aircraft.

Is it permissible to have remunerated training in a group owned permit aircraft in order to do differences training such as tailwheel training, retractable gear, CS prop etc?

Thanks,

I just did my tailwheel checkout on our group owned, Permit to Fly WAG Aero Cub...so, in short, yes
