In my humble opinion, the R22 is the biggest pile of horse manure ever produced and used in a training role. The only good thing about the R22 is the price and the running costs. Now for me the only decent trainer is the Bell 47 G4. I did my basic helicopter training in this machine back in 79. It is slow enough to enable a student to get ahead of the machine and is forgiving enough to allow a few mistakes. It is also a dream to do EOL's in. Just my opinion though!!!
