Thanks. It didn't have an engine when I bought it, and I had the 1.60 on hand. I got a pretty decent deal on it. It had all the servos (one digital)and a huge set of spring down retracts that I also can't identify. (even the tail wheel retracts) I gave the guy $200.00 for it. My friend recovered it and painted it for the cost of the materials. I'm currently trying to find a 3-blade prop for it....
