The best deals I've ever gotten were on planes complete with engine & radio. I can't help but think if the guys had gone to the trouble of separating the components, the total sales would have amounted to more money. My suggestion is to do it that way, sell engines, planes & radios separately, to maximize your total sales dollars.

On the other hand, if time is of the essence, you could probably sell the complete, ready to fly plane faster.

Good luck,
