Ryan,

Its an easy question to answer. The rules were based on a 20+ year old concept. The entire industy has changed and its time for the rules to change as well.

I've long gotten the impression that IMAC powers-that-be would like mini-imac to go away. The fact is, it could foster more involvement by making the sport more accessible. A lot of clubs would love to host an IMAC contest, but their fields/environment will not permit it.

My club has over 250 members. Many of which fly scale aerobatic aircraft. None to my knowledge have less than a .91, while most have Saito 1.5 and 1.8. Collectively we'll have to agree on a set of rules that make sense.
