I shudder when I hear 'I'm a fast learner'
Having had three failures in a career of 6000 hours I would not like to be in an twin with you until you had a few hours twin under your belt
I did my initial twin on a Lockheed 12a which is a bloody nightmare radial twin
The guy who did the endorsement gave me one bit of advice 'this son of a bitch will bite of you lose an engine on take off' having heeded his words every take off I do now is standing at the end of the runway and telling myself an egone is going to fail between rotate and blue line. And guess what two failures were spot on
Don't listen to anyone who wants to give you a quick twin rating do the 7 hours. Get the instructor to take you to mangalore with a nice long runway and demonstrate failure at rotation. If you haven't changed underwear you will have learnt how to survive
I wish you well in your career
