Suggest you hire the same type as you have done your PPL hrs build in
Your logic is sound, but that would be one long slow boring trip in a 172. I like the idea of getting some experience in something else. Of course i will have to spend a few extra dollars for training to get checked off to fly.
I've actually been reading up on some of the kit planes like the RV-7. Nice and fast, fuel efficient, could be a winner (if i can find any to hire in brisbane).
What do you guys think about a
RV-7 for the trip? Or something equivalent, suggestions?
