Wing spars

Commenced solid riveting on wing spars.  Almost completed one spar - found it difficult to set the rivets along the top of the spar doubler because of the bend at the top, so have ordered a 5.5" head which should be long enough to prevent the spring on the air gun from hitting the bent section when setting.

Happy with most of the rivets - had a couple that I had to drill out and re-set because of damage to the head caused by the gun slipping, but 99% worked fine.

Also cut the…

Looking for a William Wynne Corvair engine

Looking for one already built up so I could install it this winter.  Fuselage about all done except engine controls.

Zenith CH 650 vs. Sonex: "Competitive Comparison"

The following is an unusual post because I don't normally comment negatively about competitors.  Competition is good for any industry, forcing us to be innovative and efficient, and there is a place and market for many different airplane designs (and the companies that manufacture them): The current issue of Kitplanes magazine (December 2011) contains the annual Buyer's Guide with 316 different kit aircraft listed (from nearly as many manufacturers)!

The letter that…

Thanks So Much for the "More" Button!

I've been wishing for the last year and a half to be able to see recent posts.  I go on every day (almost), but they still get past me sometimes.

100 Hrs In

This weekend marked the 100th hour of build time and the official start of the wings. Thanks to a bunch of rookie mistakes and some plain old carelessness I think I am probably about 20-25 hours behind a "normal" build time (whatever that is) but I am quite pleased with what I've managed to do: the rudder, the slats, the flaperons, the horizontal stab, the elevator, and the nose ribs/slat support assemblies.

Adding fuel return fitting

I'm building the wings on my 650  and the fuel return fitting in on the outboard end of the tank, I talked with Zenith and they said something about that end is better to prevent condensation from getting into the tank from the return line???

Anyway, instead of running a long fuel return line outboard to the next lightening hole I'm considering welding a return fitting in the upper inboard end of my tanks.

Has anyone else done this or is there any reason I shouldn't do…

Fuel injected engines

In a previous blog about the ULPower engine in the 650 there was a discussion about fuel use.  Since these engines use fuel to cool the injectors and send the excess fuel by return line back to the tanks I was wondering how the GPH fuel use is determined. Seems that a fuel flow sensor in the line to the engine would not give a correct reading.  Just wondered how it was done.

Setbacks!

Well summer and fall came and went and I didn't do a darn thing on the plane...debating on whether to get my materials ordered so I can work on stuff over this coming winter. But will I have time? Home repairs and other life setbacks have really gotten in the way!

My new favourite tool

I'm probably the last person to catch on, but I recently bought this Olfa P800 knife for trimming skin edges and it is fantastic. No more snips and scotch brite for me.


Have to thank plane builders for sharing their tips online and unwittingly guiding me to the right blade.

Popeller pitch and size

What is the best propeller to put on ch701 with jabiru 2200 engine ??? What should the rev-counter read at full throttle when taking off and climbing ??? I can only get to 2600 rpm maximum throttle which I think is not enough. Any information will be appreciated.

Airborne At Last!

Six years after ordering my kit from CZAW, ZK-ZMX finally took to the skies with test pilot Jerry Chisholm at the controls.

 

Omaka airfield owned by the Marlborough Aero Club is a little too big for this aircraft .I'll get closer for better shots as soon as I can

Jabiru 3300A Oil Pressure sender failure

I have had another oil pressure sender failure. Thats 2 in 25 hours flying. Failure mode as follows;

works fine then you get the ocasional spiking high oil pressure indication of 70 - 100 PSI. This gradually becomes more regular until it stays on 100 PSI. For ground running tests I have connected a direct reading gauge to the oil galery to confirm a normal 40 PSI oil reessure.

Has anyone else experienced similar failures?

Working on spars

Got the root doublers, strut attachment doublers and tip spars bent up the other day.  Due to the happy combination of a Saturday morning to myself and the kids both sleeping for 3 hours in the afternoon, I pilot-drilled the doublers & L stiffeners to the spars and cut the extrusion to shape for the front strut attachments.

After some solid riveting practice, I'm now ready to attempt riveting the spars together... nervously... (jeez I'd hate to bugger it up on the last rivet!!)
