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…

He was air lifted to Green Bay in critical condition.… Continue

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??

701 Crash and 5 Bladed Props

While discussing aviation accidents with some co-workers I went to the NTSB website and was surprised (and saddened) to see that a 701 got damaged two weeks ago out where I live: accident report


But I was also excited because I thought that would mean there was a Zenith builder around but from the registration details it looks like the owner is a snowbird from Oregon,…

Oil cooler failure and off field landing: Epilogue

A week ago my Zodiac had an oil cooler failure which caused me to do an off-field landing. I wrote about the event in this blog post.  That mishap turned out well enough with a bit of skill, luck and significant help from friends.


It has taken a week but I now know what went wrong and feel compelled to share the information.  The short story is “builder error”.  The longer story…

Rotax 912 Honeywell Oil Pressure Sender

My CH750 is powered by the Rotax 912S engine. To date I have 90 trouble free hours on the engine with no adjustments required other than tightening a radiator hose clamp. While flying the other day the engine oil pressure started to fluctuate and go full scale both directions on the D180. This really gets your attention! I selected a field for a forced landing, but after flying the approach with Rotax humming along happily (all oil temps & cylinder temps normal) I reasoned I was risking…
