I have so many questions.. but if you are marketing it... the answers.. well will defeat your ultimate purpose... I think the advantages you have listed are great... and there will be a market for them...

As for willing to buy one.. no offence.. I would not.... but thats why I like Heng Long... it is DO IT YOURSELF.. unlike Tamiya which I feel is follow the book and you are done (minus modeling of course)
