I've done some testing with sub 250g planes and I'll be pumping out some serious stuff in this category for the near future. I'm going to start working with smaller motors and electronics, but I can already build a plane under 250g(possibly even under 200g) with an A pack 1806 radial and full park flyer performance and capability consistent with most mighty mini sized planes if I try(it's far from rocket science). With all the bright minds here I can tell you that if we get backed into this sub 250g category we will make the most out of it, with some great innovations
