Re: "I was thinking of taking a LT-25, removing the dihedral, making it a tail dragger, and upping the engine to like a .40 FX or even a .46 AX. Any thought of how this would work? Or anything else you could think of to make it a rocket."< First off the LT25 is a tail dragger. On the dihedral: when I built my sons I put the wings together with only 1 1/2" dihedral and the plane handles the wind really well. On the larger engines, don't do it. The plane is quite a floater on landing. I have an OS 32SX on my sonds and even with that engine its hard to get the plane to come down. Even at a slow idle, the 10" prop just keeps pulling the plane along well barely losing any altitude. I know other flyers with a 40Fx on their LT25 and they have an aweful time getting it to land. Half the time they give up and just kill the engine and dead stick it in when they have to land. Since this is to be a 2nd type plane and you are looking at good 46 engines I would agree with Manny and look at the Tiger 2. The kit comes set up so you can use trike gear or tail dragger gear. [8D]
