More form blocks

Got my form blocks done for the tail section today. Now just waiting for my fluting pliers & bulk pack of rivets...should have most of my rudder parts formed (and maybe assembled) within a couple of weeks. Can't believe it took this long to get going! Got my rolled aluminum sheet, Cortec primer and hardware from Zenith just before Thanksgiving...got about 8 solid hours of work in this weekend.

Wing parts fabrication

Cut out the 8 flaperon brackets and 8 slat supports from 0.090".  I don't have a bandsaw, but it's amazing what you can do with a table mounted circular saw, a belt sander and some patience...

Tried the new 5.5" solid rivet driver on the remaining spar rivets on the starboard spar.  Found it tends to kick around more than the short heads, so even more care has to be taken.

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…

UL350is performance in hotter climates

Phoenix hot i mean;)  Since i'm just putting wings together, I will need a fuel return line if I chose the UL engine.  So my decision may come sooner than i had planned.

 

Does anyone know of any cooling issues with this engine similar to others?   I'll be flying mainly in the Phoenix area.

 

Also, Are the 650 extended range tanks plumbed for a return line?

 

Thanks mucho!!

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.
