Ask your FI what material you require so you can learn and fly a helicopter safely.
There is a dress code if one want's to be a pilot, your instructor should be wearing 3 or 4 stripe's on each shoulder and you should wear 1 stripe.
The reason that pilot's should wear these is so that ground handler's or who ever know's who the commander of the craft is and know's who the student or co-pilot is.
I would suggest learning on the HU269
There is a reason the american military dont teach primary helicopter flying skill's in any other machine
Can't beat PPRune for good, accurate and useful information!
Personally I would suggest 5 or 6 stripes on each shoulder when instructing US military pilots in the H269, just to be safe!
