Changing from rotax to o-235

[gizmos]

I am tired of looking for a deal on a 100 hp rotax. I have my cowl and engine mount on for the 912. What is involved in changing over to the o-235.

What model plane?

[TahoeTim]

hang in there, I went through a bunch before finally finding mine

i even tried to get guys selling planes to part out the engine!

Have you considered an 80hp 912UL then adding a Zipper conversion?

I would wait, the 0-235 is a lot heavier which will reduce your range or payload considerably. Tom

I think to get a FWF set up with new cowls for the 0-235 would be in the $4000 range

I have a kf5 vixen with kf 7 cowl and elevator set up.

I have the engine mount with the ring adapter for rotax, what will I need on the mount?

I drove from va to key west Florida for a engine that had on 283 hrs. When I got there, I could have beat the guy up. He was an attorney that had inked the books. Seven years, not one annual, no inspection records, log book did not match engine log and prop was sent out for reprinting but he said there was no paper work. I was buying the plane for the engine. Well, after 15 minutes, I left with no engine. I sold my rv6a last year and started on my rv9a kit. My kf has everything done except engine , I have a panel done for a rotax with dynon set up.

Not on topic but relevant.

Within the last couple of weeks I saw a 912, I think UL, with 1000 hours for sale. If memory serves, it was on Barnstormers. The engine was purported to be a early government model. It may be bad information but I think Rotax engines have been used on UAVs. If that is correct, I would think there should be some available through the surplus auctions.

FWIW

Hey Lou. My 914 was a former uav engine. Rotech Research in Vernon BC sells these engines after they remove the Milspec turbo and put in the Rotax one.

I saw the one on barnstormer, it has some issues, but gov auctions I think might be a great ideal ! I have some great giant scale rc that I am going to sell to fund my projects.

Thanks for confirming the correctness of my thoughts.
Any guesses on how much Rotech Research fetches for them?

Hey Lou, I actually bought mine off of a guy who had an accident with his Pelican so I didn't pay Rotech prices. They factory zero them so when you get it, it is basically an overhauled engine with a brand new turbo. I have heard that you can get a Rotech 914 that was used in a UAV and zeroed for the same price you can get a 912ULS new. I also think they don't always have them available.

WarEagle also has one of these from Rotech in his plane.
