I don't know about the simulator but I do know if you stick a super tiger 90 2 stroke on that tiger 60 you can practice 3-D all day long and have unlimited vertical.

well i do know that one 17 year old kid in our club practices IMAC all he can on the simulator and took 2nd place in some big meet in indiana.

But, on the other hand another guy thats been flying for 2 years has had 3 different simulators and didn't care for any of them.

Only real way to find out is to get one and find out for yourself. Me, I'm saving my simulator money for 2-3 cases of fuel to get me through the 1st month of flying this summer!
