As webmaster for NW HobbyTechnologies, I would recommend one of our GeeBee Z's or R-2's, and I'll post the link below for each. But it seems you may be looking for a smaller model than that, in which case I have an Adrian Page Z that I may have opened and looked inside the box, but that's all I ever did with it. I'll be happy to give somebody a great deal on it. You pay the shipping charges. I think I paid about $120.00 for it new, so you can use that as your reference for your offers.
