i was thinking glow too, but you wouldnt be able to do it with this fuz, that would have to be a redesign. all the cutting on that fuz takes alot of time and $$$, me thinks a glow version would need less cutting and therefore be cheaper to produce.
as for tank posistion, it looks like a President funfly to me and that also has a nose that looks long, but you use most of that with an engine, the tank is just infront of the wing and it dosnt seam to effect the CofG a whole lot even on the lightened Kazba versions.
