...and don't forget the cost of electronics and equipment time for assembling plus you still have to test the turbine once its assembled. Cheap is not the correct word here..even for the least costed turbine with simplest features. Just go with what you think suit you best...saving on lowest cost radio gears as well? Cost justification wouldn't hurt and see how much you really end up spending on one ready to fly jet...we are usually surprised and many times things that we try to cut on caused us dearly.
