Well, it's tough to serve 2 masters (3d and pattern) with one plane. it can be done but it's tricky. If your plane is not responding well to inputs, it could very well be out of trim. There is an excellent trimming chart at http://www.nsrca.org/ and also a lot of good information about pure pattern flying, set up and teh manuevers. Also I would recommend visiting http://www.mini-iac.com/ and just spend a little time going through both pages, there is a wealth of knowledge there.

If you are looking for something that will show you very detailed descriptions of the manuevers themselves, I'm not sure if it exists.

Also you might want to consider getting a pure 2 meter pattern plane and doing some competing in that arena as well. IMAC is great, but pure pattern teaches you some important flying disciplines that IMAC does not. A person who excels at IMAC usually has a pure patern background, with a few notable exceptions. Plus it's cheaper, and you can effectively double the fun [8D] Just a thought.

A Sukhoi is a good play plane, but isn't the best for prescision. An Extra 330L is about the best there is in that respect. If you need more specific info about an IMAC type set up, I'd encourage you to check out the IMAC forum as I'm currently of little help in that specific arena. But I'm still more than willing to help however I can.
