The new kit is available at the following link: http://www.bridiairplanes.com/hangar/aircruiser60.html. The specs for the plane are also in one of my earlier posts in this thread. I think that a .60 size engine is overkill but I don't have any idea about the older .60 engine since I have only been in the hobby for about two years. I know that my .46AX works great for my LT-40 which is at least 5 1/2 lbs. I have no experience with the Magnum .40.
