Playing with the wind: The big circle

It is said that when making a round trip any wind is a disadvantage.  While you may have a tail wind in one direction, you will have a headwind in the other.  You will spend more time in the headwind then in the tailwind so overall, the wind will increase your trip time and increase your fuel burn.  I have found sometimes this is true, other times it is not.


Today’s pilot has powerful weather tools to help fly safely and sometimes more efficiently.  Now if your only going up…

What's wrong with this picture.

If you look at the first picture of the side skin layout you will see what I missed. On one of the skins the rivet line for the front HT bracket is off by 16mm Not sure how it happened, of course I didn't discover this until after I drilled the line. 6 hrs work down the tubes! Ah the joys of scratch building. At least I can use the material for smaller pieces. Got the right side skin clamped up, and will remake a 2nd skin next weekend. Press on from there to the next screw…

CH701 standard door windows

The photo assembly guides depict the door window plastic being installed sitting on the work table.  Absolutely put the door frame back into the jig before pilot drilling the window to the frame!  Finding this out the hard way:  door was twisted and would no longer fit in the cabin opening.  I was able to reposition the assembly in the jig and re-drill the pilot holes in the bottom edge and forward and aft door frame tubes and salvage the Lexan plastic.  The upper hinge and the door side…

Leaking CH701 / CH750 / CH801 tires

I think most builders have at least one slow leak tire on their aircraft. On mine its the nose gear tire, it leaks down over a couple weeks while the mains have never leaked. I was thinking about putting tubes in the tires, but that adds extra cost and weight (I assume that is why tubes are not included in the kit?). A fellow builder Bob Stuart (CH701 plans only) suggested removing the valve stem and injecting (syringe) 5 - 10 cc of anti-freeze then installing the stem and inflating the…

Floating Aircraft Dock

Ok, so here is your challenge - a floating airport.


We are seriously considering taking on a disused hospital ship and converting it into a 'Health Education Vessel with Advanced First Responder Capabilities'.  If successful, which is more than 50%, we would want to keep the vessel at large the majority of the time, anchored at a number of points along the thousands of kilometers of lake-coast on the largest man made lake in the world.  Moving crews and supplies on and off…

An Australian Adventure

Recently my wife (Mary) and I journeyed to Australia in celebration of her 50th birthday.  Being long-time EAA members and homebuilders, part of our vacation planning included establishing contact with Australian homebuilders who lived in the regions we were going to visit.


We've always enjoyed meeting fellow aviation enthusiasts.  Some of our most enjoyable times have been in the company of aviators who we've met at various places.  From small fly-ins at places like Brodhead…

1st Flight after cooler swap

Had the opportunity on Friday to get into the air for a test of the new oil cooler. 

 Lots of traffic  and had to spend a lot of time holding short for takeoff, oil temps remained well within limits, Left bank CHT's got a little warmer than I would like but remained within limits. managed to get about .8 hr of flight and landed to check for potential oil leaks. Found one connection that needed tightening and will check it again on the next flight. Minimum loss of oil.

Arm Rest Interference


Is anyone having issues with the back of the armrest sides being approx 10mm higher the the tunnel top panel when installed.


This problem has been dogging me since joining the rear and front fuselage. All other parts and pieces seem to line up just fine.



Any help or comments would be greatly appreciated.

Progress report

CH-701 C-GBQX became an airplane on November 1st, 2010.  I now have about 36 hours on it.  Phase one ended at 25hrs and I have been enjoying giving ride to my friends. 


I'm building streamlined strut covers.  With my 80 hp Rotax the plane cruises about 78-80mph at 5200 rpm when solo.  I'd like to get just a bit more performance out of it.  That and maybe a bit better climb on hot days (if they ever get here).  I'm hoping to fly it to Oshkosh this year so I need to get these…

Right Airframe, Right Engine...

As part of our approvals process in Ghana we are required to undertake regular training and to keep our 'engineering certificates' up to date. consequently, Patricia and I, went to Europe for training. Since the training was the week after AERO Friedrickshafen (Europe's Oshkosh), we went a few days early, and met with other engineers and homebuilders from around the globe at this event.

Doing what we do, it is important to remain abreast of the latest developments and to assess if we… Continue

Funny how life works

Well, as I was cleaning up my basement all winter, trying to make room for my workbench, I found a bunch of severe, floor-to-ceiling cracks in my old sandstone foundation. Unfortunately, addressing the structural issues has taken front seat to getting started on my plane. However, looks like I'll be finally starting nicely on the tail surfaces within a few weeks...

Bleeding the coolant system...

I changed out some hoses on the ship (912 UL) and now I've got it back together... but I can't find any secrets to bleeding the coolant system other than just running it hard, then cooling it for it to suck up the  recovery tank and then do it all over again...


any secrets to bleeding the coolant on a 912 UL??
