I have flown many types of turbine trainer, but hands down Bruce Tharpe's Reaction is the best!!. Its is big, flies fast and lands very slowly. Excellent for grass runway or short runway. In past I have flown from rough grass strip but never once I had any issue with landing gears. Currently I am flying my reaction with P60 from 400 ft paved runway. This aircraft can land and take off in just 200ft. And above all it is hassle jet, and has access to everything once you open all the hatches incase you need to repair or regular maintainance
This is one aircraft I love to fly, and is truely an "everyday jet."
The only downside is that reaction is in kit form and if you dont mind building this is THE AIRCRAFT!!
