Deal of the Day, 1/24/19, pt. #2

SORRY, THIS has SOLD!  Stay tuned for more bargains…


This is round four,  I will have more stuff later. Stay tuned.


I am working my way through a once a decade total hangar clean up, and I have come across a great number of slightly used items that I’m going to sell here. I have enough items that I can put up one or two a night for two weeks.


Because  everything, including warfare, has ‘rules’, here we go:


A) If you want to buy something, you have to have a Conversion manual of mine. If you don’t have one yet, I suggest you go to my products page and order one. (Just paying for one is good enough, you don’t have to have it in your hands to claim one of these items.) To get one:

Shop – Products |

( Or call SPA at 904-626-7777 during regular business hours. )


B) If you see it and you want it, all you have to do is be the first builder to say “I’ll buy that” in the comments section. Please put your first and last name in there and the city you are from. After that you can text me your cell number at 904-806-8143 or Email it to me at  If you are the second builder in the comments, do the same in case the first guy forgets to contact me for more than 24 hours. 


C) I’ll cover the shipping on this stuff, as long as you are in the US.Outside of uncle Sam’s turf, my friends from abroad will have to cover shipping, tags, permits, VAT (whatever that is) and bribes to postal workers. I’ll deal with my broken government, you guys deal with your own taxmen and bureaucrats. Fair enough?


OK, with that all covered, on to the second of this evenings “Deal of the Day”



Above, a stainless exhaust system. It fits all models of Zenith 601/650 series, All Zenith 750 aircraft, and also fits Bearhawk LSA aircraft. This particular set has never been flown, but was run several hours in ground tests. The variation in color is just because I got started cleaning them to polish them 304 stainless can be turned into a chrome like finish with some effort, but these can just be cleaned a bit by hand. It has been drilled for 6 EGT probes, but I can weld these shut in minutes if the new owner desires. New sets go for $659 plus shipping. Deal of the Day on this slightly used set: $459, shipping included.







About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 30 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at and in more than 50 magazine articles.

  3. “I’ll Buy that”. Rules followed. William if you scratch up two sets extra, you have a buyer for the third set on hand.

    • Vern, over the weekend, follow the stories I put up, I have developed several new universal exhaust systems I will put up stories about. They are for applications like yours. A zenith exhaust system would likely not fit a mount for a cappella, but the stuff I have made recently would.

      • I liked the mount you built for your Buttercup project. Because of the gear location and the ability of the Wittman gear to align I expect the aircraft to have less aggressive ground looping tendency. Would the newer exhaust designs clear the Buttercup mount?

      • Yes, I’ll mention it in the posts. One of them was built for a buttercup builder

  4. John Edwards says:

    I will buy that….the stainless exhaust set up if it can be made to fit my CH 701 3Ltr with a Roys Garage motor mount 253-302-1018

    • John, A 601/650/750 exhaust like the one pictured will not fit a 701. I know your mount design, The fixture it was made in was my old one I gave to Roy many years ago. Keep an eye on the new exhaust stories, there are systems,ms suited to the 701.
