I have one and LOVE IT! Its powered by an OS 46AX. Let me tell you that the 46AX is PLENTY of power for this plane using an 11x5 prop. I get great verticle, knife edge and am able to hover. I only hover it at higher altitude as I dont think this plane is able to recover as quickly as a 3D plane and as we all know...it isnt meant to be a 3d plane. I highly recommend it. Make sure you reinforce the landing gear area inside the fuselage with epoxy just to be safe. LOVE IT LOVE IT LOVE IT>

UPGRADES: The only things I changed right out of the box was installed real axles on the landing gear instead of the cheapo bolts it comes with. Also installed a sullivan tail gear assembly instead of using the OEM tail gear which is glued into the rudder(im not crazy about the idea of gluing tail wheel into the rudder because of the stress it causes. Just my opinion.)
