with their CFI who nearly killed me due to running out of fuel
Let me tell you running out of fuel in an Enstrom is a "non event". I suspect you were more scared due to ignorance of how well they glide. The fact you are talking about it proves that.
If ever I could choose which type to run out of fuel in, it would be an Enstrom.
