I'm finally having a ball with this one! Crashed it twice with a Magnum 52 that was not set up properly! Pilot error I'm sure wrong prop probalbly! That's history now! So Mores law applys!! If the engine your trying doesn't seem to have enough add more! I had a Magnum 46 on the bench looking for a Home! It found a very happy one! I added a Pitts style muffler! I Had to add a little weight to the tail not much. You could probably hand launch this one straight up! Flys awsome, Lands nice a little hot but I think I can slow it down now that I'm getting use to it! I replaced the Landing gear with the gear with something stronger! The only thing I'd like to Improve is the roll rate! I've got all the deflection I can get out of the ailerons and it slow roll's! Snap rolls are a different story! Knife edge no Problem! All and All a Great flying Bird! I have the blue one and the colors stand out fine!
