Here is an older series (1970's),  O.S. MAX-S 30 Control Line/Free Flight engine with #703muffler. I flew several of these and the .35s in CL stunt models many years ago. They were and are great engines of the period. . Recently acquired from an estate. The engine turns smooth, and has good strong compression. Engine was part of a display for several years. Never mounted in a model and never run. Only issue with this one is it may still have a bit of dust on it, and the NVA was never tightened up and turns in the venturi.

$7.00  shipping in U.S. Can be combined with other auctions to save on shipping costs                                                        

NOW THE FINE PRINT: I want everyone interested in my auctions to be aware I am the only guy here and I have a full time job which takes me away from home a lot. I do not always have online com available. I try to ship twice a week, usually on  Tuesdays and Fridays.  I will do my best to make sure you are happy with the deal, if not PLEASE let me know, we can work out any misunderstandings.
