It appears that you may have several issues with the plane as well as - perhaps a general lack of flying experience. A simulator is really the best and least expensive trainng aide you can buy. Well worth the investment. You also need to ascertain if there are problems with the aircraft itself. In that vein I did a very quick search on the user groups here and found a link that will give you some ideas on what to check for. There are several addtional links in the post so check each of them out and take what you can from the information shared. There should be enough information to at least get you headed in the right direction. I must say starting out with a twin is not what I would have started with! Way too many variables for a newbie, but it seems you are determined so take a look and see if anything from the link below will help you out. If all the sugestion check out then at least you can take a look for your problems elsewhere.
