Accucraft AC78-801 Shay - 13 Ton Open Cab

Just got back from the National Garden Railway Convention 2010. Picked up an Accucraft AC78-801 Shay - 13 Ton Open Cab,

I have a couple questions if anyone has one of these. 1. Mine did not come with a manual. I checked the Accucraft website but didn’t see one. Does anyone have a manual for one of these? 2. I am curious what the minimum radius curve one of these will run on. I see that the front truck when turning to the right turns quite far however, the turn to the left is much shorter before the front drive train falls out of the socket. 3. The back truck swings out quite a ways to the left but is impeeded from turning much past the center to the right. Not sure what is hanging it up. Cheers timmyd
