I mean you hear it go WAWAWAWAWAWA! as it rolls, the rate is so fast. You really want to cover it with VERY contrasting top and bottom colors on the wings. Flew it today (just had to after posting about it last night) and had a real blast with it. I swapped out the 10/5 APC for a 10/4 APC I had and got closer to hovering it. Really needs more rudder.
I would have to open up the hatch and check but I am pretty sure I used a standard sized (600mAh?) rx battery. I have no idea what it weighs as I dont have a scale. Also dont remember where I stuck that battery.
If I were to build another one (I surely will if I destroy it beyond repair) I would mount the engine on a slant or sideways so that the muffler was under the fuse. Top of the wing and tail group gets REAL slimey. Picture here. The underside of the wing and stab is black Ultracote. Pretty easy to tell top from bottom during those insane rolls.
