Builders,
Zenith 601-HDS / 2,700cc Corvair builder/flyer Larry Nelson, of Yuma AZ is the first builder to send back confirmation of flying my new ‘STOL Bowl’ .

If you want to make sure you see all the videos we put up, please subscribe. I encourage this for the secondary reason that we will be able to put active hyperlinks to stories in the video descriptions as soon as we have 1,000 subscribers. It will do a lot to tie in previous stories I have written to each of the videos. I’m trying to get to this threshold asap.

Above, Larry with his bird. Even though it was intended for STOL planes, the new nose bowl really has no measurable drag penalty on faster aircraft, and it will provide significantly enhanced cooling on any Corvair powered plane. Larry’s home base is 10 miles from Mexico, in one of the hottest places in the US. He selected to replace his original standard bowl with a STOL bowl to improve his cooling in advance of really hot summer weather where the average daytime high is 105F. The exchange was direct and only took a few hours. the gray color shown is the smooth gel coat the part is shipped in. Painting is an option.

When watching the video, Larry speaks of oil temps now of 220F- keep in mind that with Corvairs flying on my Gold oil filter housing #2601, I’m intentionally measuring the temp. before the cooler. The oil we use will not have a problem at sustained temperatures near 300F, but I consider anything over 260F before the cooler excessive to the engine. Oil is only half the story, as Larry also saw a very significant reduction on CHT’s particularly in a hard climb.
.
If Larry’s name sounds familiar, it is because he is also our selected oil analysis expert. Check out this story: Corvair Oil Analysis. This program will shortly be the subject of another video. Larry is also remembered as the guy who paid for the parts in his engine with ammunition: Acceptable methods of payment for Corvair parts. Quite a character.
