Tipsy Nipper it is.
If you can learn to do decent aeros in a Nipper you'll do them in anything !
A Nipper with inverted fuel and oil systems is a rarity, but they do exist.
Cheap to operate , safe but strong (sounds like something else !) and fun.
Barry Smith has the oldest Nipper in captivity, and you'd be impressed if you'd seen one of his displays.
