After 6 years of flying with a EA 81 Subaru engine I am tired of expermiting with trying to correct a cooling problem.

I am giving up on the subie and am in the process of buying a used lycoming 0235 C2C 108 hp engine. After I get the lyc inspecteed and ready to install i am going to remove the subie complete with motor mount, prop, radiators, oil coolers and all other items attached to engine and weight it to give a camparasion with the lyc. I feel I can install the Lyc at the same or less weight as the subie.

Any body have pictures of the Lyc installition and exhaust on a Zodiac please let me know or forward to me.

Thanks

Dave

I had considered the 0200 but decided on the Lyc. Seemed like there were more available and better prices. I think I can get the weight to the same or less than the subie. I have had to add many mods to keep it cool. The mods have added a lot of weight and require a lot of maintance. Thats why i decided against the corvair, it is a highly modifyed engine and you cant just go anywhere for help. The Lyc is known by everybody and you can get support at the local airport.

I'd choose a brand new 0200 lightweight cont if I had the cash. Most likely source a used 0200 for my install, although probly say the lyc is a better engine, dont know if its that much better to justify the extra weight depends on what you plan on carrying I guess. Be very mindful of rusty camshafts on used lyc can be a bit of trap a few years down the track

Dave,
you should really talk to Larry MacFarland of Macs Machine.com
He has a subi running well in his 601hd and the radiator is in a scoop under the fuselage like a p51 and it looks sharp!
But the Corvair will save you about 100 pounds......(I've heard)
The Corvair is well proven too.
Just my highly biased opinion...... :)
Weigh your front wheel and let me know what it is and I'll weigh mine....

David - I believe your making the right decision to go to the aircraft engine. Very few auto conversions are as reliable as aircraft engines. Off course there are exceptions but they are just that exceptions not the rule. Flying doesn't lend itself to to much experimenting. My best friend was stuck on the V-6 STOL (Ford engine) until the engine developed one problem after another. The plane is yet to leave the ground. He finally decided to junk the engine. Good luck and happy flying.

I also went flying today, was able to get the subie running a little cooler. Still am going ahead with the Luc. I live in Scottsbluff Nebraska where there is a lot of wide open area. lots of open fields for landing. I would not even think of flying over hostile terrain. My subie install has never let me down but i spend about 1 hour checking everying for every 1 hour i fly. with my budget it will take me untill the end of the year before the lyc will be ready so will keep up the intence maintaince to keep flying.

Aircraft with auto conversions have much lower resale value. In these depressed economic times the resale value is not there for auto conversion aircraft at all. I flew 2 hrs today in the CH601HD Rotax 812 80 hp C-IDUS AULA. No problems and a safe flight over hostile terrain.

thanks for your thoughts, my hanger neighbor has put his kitfox down 3 times from engine problems with his NSI Subaru. He has been lucky.
Another thing a friend pointed out to me is that the plane will have value with the Lycoming engine.

I personally know two CH601 fliers that no longer use the EA 81 engines, after putting down several times with "motor issues" the 3rd time killed the pilot. The other fellow was hurt badly and totalled the CH601HDS aircraft. I also have a friend with a 6 cylinder Subaru in a Murphy Moose...has almost as much money in it as a IO-540 and it still wont run right. No one will test fly it anymore. Any used aircraft engine is better life insurance and a car motor. Your life, your invested money & effort in an aircraft is better protected by an aircraft engine. The engine is the last place to try to save money on an aircraft.

I got a very good deal and I have looked at the corvair. Even went so far to get two core engines but looked at all the mods that needed to be done to make the corvair airworthy i decided against it. The subie has wore me down. It also required a lot of mod of witch i done my self. Willian is now selling complete engines but i think i can get the lyc installed for less money. As far as support I can build the mount and the cowl and have support with the lyc through the local Avaition collage and it is a very proven engine. thanks.

If you are not totally committed to the Lycoming yet, I suggest you give the Corvair (William Wynne conversion) a look. The package was developed for the 601XL but bolts right up to the older 601 airplanes, as well. It is a strong, smooth engine with a completely proven installation package. The Corvair will weigh a little bit less than the Lycoming and has a well integrated installation package available. A friend of mine put a Lyoming in his 601XL and learned, to his surprise, that Zenith's support of that engine consists of a motor mount and a fibreglass cowling. After that, you are on your own. And, icing on the cake, the Corvair will cost you a fraction of the Lycoming (unless you got one heck of a deal).
