Anybody have any experience with a Real World Solutions efi in an EA81. It acts like it is not getting fuel. I've checked everything and I'm just about to give up.

EAA One Week Wonder on Tour in Central Florida: March 2015

Here's a summary of my three days with the EAA One Week Wonder airplane in central Florida earlier this week. 

On Wednesday, we flew by the shortest paved runway (a nice R/C field, just a few hundred feet long) and later that night I had the chance to fly over the longest runway I'd ever seen (NASA's shuttle landing runway at Kennedy Space Center, three miles long!).…

Video of the Rock House Landing in California Desert

Kind of learning how to use a video editor, much harder than building a plane! Here's a link to the video.                                                       Chris Brown STOL 750 Rock House Landing

DIY avionics

The flight instruments (namely the artificial horizon) is now being driven by the MPU board (MPU9250 -> Arduino -> iMac).

Eventually all of this will be put together and run on a PCduino with its own screen.

More work to be done. Fun, but slow.

Here's a video:

Vancouver Island

I am spending February on Vancouver Island escaping the bitter cold in southern Ontario. Are there any builders on the Island? I would love to see your project and offer free advice ... or find out you know more than I do and learn from you. I have 600 hours on my 701 since first flying it in March of 2011. You can contact me at

Ugghhhh...Cutting my spar

I attempted to cut one of my wing spars with the olfa knife and may have messed it up. On my initial pass, the angle aluminum I was using as a guide moved about 1mm. I ended up having two areas where it goes from 209mm to 208. From the way I read the construction standards this is past tolerance. Is it worth a call to Caleb to see if this still usable? I Had a bad feeling about attempting this with the scoring knife when I started...should a listened to my gut!

My zenith aircraft

I have built two zenith kits in the past. My first one a ch701 was built in1991-1992. It originally was powered by a rotax 582 for about 300 hours. The 582 was replaced with a rotax 914 to give superb performance in the mountains where I live. I have put 1200 hours on the 914 now and I have nothing but good to say about the 701/914 combination. The airframe at 1500 hours is in excellent shape.

My second zenith is a ch801. It is completed and has been flying for about 125 hours…

Finally building

Started on the Horiz. Stabilizer and just finished cleco-ing the front spar assembly.  Logging everything and taking pictures for the final inspectors.  Also trying to keep a good track of time spent.

More Parts!

Don't have a shop with a bunch of equipment to make it easier but still plugging away. Everything so far with a ruler, jigsaw and a file. My local EAA has a big metal brake so I'll bend the pieces needing bends on Tuesday hopefully. Its kinda fun fabricating you own parts. I just hope they fit/work when assembly time comes.

Scratch building!

My first scratch built pieces! Not sure if I'm up to the task to do all the wings this way but I've got till march before the fuselage arrives so why not give it a shot. Starting with some small pieces out of some 0.032 and 0.063 T-6 I found at a local metal place. Also working on forms for ribs. Slow going but it's progress!

The geese are back

The geese are back,

A few weeks ago the snow geese started to arrive in full force and spread out all over the valley in which I live. This started about five years ago and it seems more and more are joining the fray.  Winter wheat   planted in fall stands about two inches high at this time of year is tops on the menu. Flocks like the ones shown can destroy a field in one day, it is to the point farmers are planting more corn in place of wheat. Along with some corn my land is planted…
