If you want to accuse me of posting "rubbish"and "rot" that is up to you, however I have been operating them for over two years now, each aircraft averaging three hours a day; and perhaps, just maybe, I know a little bit about operating them and how cost effective they are as trainers. If you can only carry 20 minutes of fuel then your average bods must be enormous.
The Boomerangs certainly haven't been a waste of my time and money.
Quite happy if my competitors carry on buying the tupperware trainers or using the old hardware if that's all they can afford.
