I am sorry have I missed something, how is this aircraft cheaper than the R22 !!!
And unfortunately ask yourself one question, why is the R22 the training aircraft......... Because it is far more cost effective, that is how training schools are able to make some small amount of money, the r22 was not meant to be a basic trainer, but due to fact of financial constraints it has been the most popular trainer for the last 20years.....
