Not really happy with it; it was a gift so i shouldn't complain. I do not know the weight but at a guess, 12.5 grams (w/a penny weighing 2.5g) or more. It takes 3 quarters taped to front to glide. I will try hot glue next. One side of the foam is a matte finish, slightly porous but the other side is more glossy. I don't think it's a plastic covering but might be that they use heat to somehow flatten it out from rolls so maybe the side that the heat is on becomes glossy?
I will make a crude balance scale to get a better idea of weight. But I'll be putting a new 06' aa guts on it soon so we will soon see if it flies under power. I like that I can mount the props well protected within the structure so they probably won't be damaged in tests. But I don't like the overall drag profile of 3.5mm for every piece of it, that's alot of resistance when you add it all up. If it flies I might make one out of aluminum. drag profile would be way less.
I haven't given up on the extruded polystyrene foam yet though.
If it's that light with the coinage it should fly nicely.
One way to find out if it's coated is to sand an edge of a scrap piece. If it
balls up or leaves a fuzz on the edge then it's coated with something. See
if you can pry the coating off with an X-acto.
If you think there's too much drag, sand a rounded edge to the LE & TE of
the wings.
I just gutted my stock AA jet. The plastic board mount is smaller than the
AA bipe and the antenna wire is thicker. It's also mounted better. No hassles
cutting that plastic tail boom like on the bipe. The switch is better on the jet too.
The jet makes a better mod than the bipe.
Much easier.
I cut the slots in the F22. They're cut much like the original AA jet.
The outer edges are cut on an angle and then sanded. It's not a squared
slot.
