I would have liked to have the battery tucked in somewhere but I dont want to cut a big hole, it works perfectly where it is, and balances the weight of the servo board and pushrods pretty well. I usually fly this one and put it back on charge rather than swap the battery. Its a piece of masking tape so it is very easy anyway. It is hard to see when its flying past so I think it will stay like that. I am impressed by the way it can fly slow, where it climbs on first notch of throttle or fast without much tendency to nose up all the time. The wing is undercambered where it meets the fuselage but flattens out near the tips. And it has a safety feature, sort of. As the wing is made in 2 halves, taped together and held to the fuselage by the wing slot/cockpit and 2 rubber bands, it can actually fold if subjected to too many Gs, then ping back level again. Continuous loops are possible with this little plane but full throttle tight loops cause wing fold. It has amazing control for an undercambered rudder and elevator model, and a very respectable glide as well. I flew this little plane from my garden, standing beside my shed, confident I could get it in past the telephone wires and our washing lines. I took it up till it was higher than I have had one of these little planes, shut the motor off and glided down onto our lawn. It can turn pretty tight so I managed to avoid the neighbours fence and get down without damage. I did this until the battery ran out, about 15 to 20 minutes of flying, long glides helped extend flying time.
One of the best handling of my 'F949 board series' of planes. (and a skydiver)
