I think the constructive criticism comes from looking at the current grumania models. They are extremely nice and" scale". The 262 is on my must have list, as it is the best looking one i have seen. So many are probably wondering why someone who spends such time and money on the previous models is suddenly ok with letting some issues on a new set of models slide by.
Granted, we all want those sport scale models to bash around the sky on occassion, but i think many others are just as interested in doin scale airliners for competition as well who are looking for a good starting point.
Either way, these will be a big hit, and i am interested in one, i just wish their was a dc10 in there
