E-1 Getting an Upgrade

We’re into the rainy season in the Pacific Northwest! The forecast said the fog would burn off by 10 a.m. this morning, but I took the picture below at 10:05:

Even if it does clear up here, because a valley separates my house and Harvey Field, where I keep my Decathlon and Arnold keeps the E-1 and his other airplanes, it’s not unusual for the weather to be clear over my house but still foggy at the airport.

Fortunately, the Harveys have this nifty weather cam you can use to check the weather (click here for the weather cam). One good thing about days like this is there is no temptation to go fly, so I should be able to get some work done. Unfortunately, I have yet to drive a single rivet on my RV-8 tailkit. But I have managed to do a few things towards setting up my workshop.

In other news, click here for a story of mine that ran in the October issue of Air&Space/Smithsonian. I don’t think Arnold had this same problem on his record-setting flight!

And yes, the E-1 is getting an upgrade to the engine! Arnold has found a modification kit that should make the engine run a bit cooler and take care of the problems that have grounded the E-1 since last summer.

It’s not unusual for experimental aircraft to have problems with the engine overheating. The vast majority of small piston-driven aircraft use air-cooled engines, and getting the cooling right is more art than science. You want the cowl that covers the engine to be as small as possible to reduce drag and weight, but a smaller cowl also means less room for the air to move around.

No word yet on an installation schedule for the modification, but I’ll let you know as soon as I have more details. In the meantime, the E-1 move to the Experimental Aircraft Association (EAA) Museum in Oshkosh has been rescheduled for next spring.
