Its the same as the Ultimate 30 have had two of the 30's one with a 48 MDS twostroke and one with a Magnum 52 fourstroke. They flew great, I did find the twostroke seem to handle better on the ground that the fourstroke, less squirrely. Lost them both the same way got into a spin and did not know how to get out of until the aircraft hit the ground.
Have 40 on order and will have someone teach me how to get out of the spin. I really liked the little biplane fits in the back of my car assembled (Scion XA) and its well made.
