I have one... I use from 3S 2200 mah to 4S 4000 mah (carved a bit of foam)
Expect it to snap the "flying wires" or pull the mounts out.
Watch for the spar inserts to come unglued (wings bending a lot? That's it) Over appx 1.5 years I've had to re-glue the spars twice.
The cowl is VERY FRAGILE. Coat the inside with E-6000 craft glue appx 1/16 in thick in the lower front and tapering thinner as you go back and up. that will make it resist breaking on a gentle nose-over.
Pez people make great pilots for it... I have Mikey Mouse and Minnie Mouse in mine.
The Tiger Moth is actually one of the best trainers you can get.
