I read somewhere that the Bordak 40 is a drop in for the OS 35-S.
I used to run the OS 35-S in a lot of planes and still have the planes, but all my 35-S engines are over the hill. If this isn't the case could someone let me know what engines would do that job for me.

Thanks to all for the help.

Take care and keep the wind to your back.

Knash,
Yes, the Brodak is a drop in. The only differants is the cylinder head is a little taller and the needle is of just a small amount. The big differance you`ll find, is that it has more power than the OS35S.It is a very good engine. It will haul about 600 in.plane just fine. Hope this helps.

Hey Ken, how ya been?

Yes the B-40 will drop right in, the only thing I had to do was open the needle valve hole a little as the needles are in a diferent place. Almost forgot I also went to a 4 ounce tank, the 3 1/2 just wasn't quite enough.

Great engine, more power and less vibration than the 35S. Hate to admit that as I have 3 GMA reworked 35's that I have allot more in than I could ever get back.

Thanks to everyone for the comments. I have fussed with this for a long time. Now all I have to do is get a B-40.

Bob it was nice to hear from you. It has been a while. See you in Tulsa in a couple months.

I still have some in stock and Brodak just got some in. I think the big rush is over, so I don't think supply will be a problem now.

However, one never knows.

That's good news, now I won't have any reservations when recommending the engine. Before it was "if you can find one".
