Hi Paul,

Yes, the cowl was off. He had the radiator mounted below the belly to get the cg right. I'm trying to somehow convert the tape images of my video camera to digital format. As soon as I succeed, I'll post some pics. I took extensive footage of this aircraft.

I'm trying to find the builder via the net, but no luck. I'm keen to get more info as until now I though that what he did must be standard practice.

As soon as I find more detail, I'll post here.

Regards,

Hennie

Hi Hans,

Yes, it was a 13B installation on a Poliwagen. This builder definitely got rid of his
complete oil system including oil cooler. I've got the video on tape to verify this.
What amazed me more was that he was using regular engine oil and not two stroke oil
as would be expected and when I talked to him he already had many problem free flying
hours on this installation.

Regards,

Hennie

Wasn't the Poliwagen designed for 65 to 80 HP VW power?
If you don't run the engine hard it might be OK without
an oil cooler.  It must have been really nose
heavy. Was the 13B using a 12A water to oil heat exchanger
under the oil filter?

Did you see it with the cowl completey off Hennie?

Did the rad installation look something like this?
