Biplane as first tail dragger ?
i have my first bipe being a first tail dragger too.
it is a Wayferer hobo ( svenson kit ) .
if you are well versed in flying your trainer then i would say go for it. i had been flying my trainer for about 1.5 years.
although the take offs are different from the trike planes you will get the hang of it after a couple of ground loops.
the landings are different as they need power all the time.
it was fun to learn...
