Yeah right - At the markups that modellers are generally willing to pay, the Chinese Penchant for "implementing" other peoples good ideas into their own products and the cost of legally protecting ones design against copying - The OP would be lucky to make much more than a basic wage for 6 months (which is about how long it would take for the low priced copies to appear).

It is a great concept and I do wish you well Umran. You could easily expand the concept to be a "Starter Generator" also and then you will have a greater potential market such as long flying time planes like UAV's.
