I just searched Seagull, but not sure. Paint scheme changed but also horizontal stabs appear to be flat; mine are sym-airfoil.

Funny how some of these model companies have no websites.

Oh well, but it was actually a useful task to do the weighing... useful to know that it looks like it will come in a little lighter than average; will have better idea of what to expect when I fly it... and just have a feeling like I know the plane better to start with... every little helps.

Think I might need to reinforce the fuse sides at the wings though, because it looks on the thin side, so that will add some weight. Perhaps could be that your club mate did some modding to the plane?

But turns out that I've thought I should go with the 2 cycle 46 at first afterall until I get confident with it. Then maybe later a four stroke roar will suit the Mustang nicely

Thanks for your help
