Elevator Trim Tab

Hello All, simple question, how did you guys debur and corr X the inside of the pre-molded elevator trim tab?? It's tight.
Secondly, should I prime the hinge barrel too?
Thanks Aaron

Building a CH750 and making modifications along the way !!!

July 20th,2016

Hi all,

I've constructed most of the elevator skeleton and made some changes. They are :

1) tip ribs are made of 0.025 (instead of 0.016) for added strength

2) Tip ribs will be constructed from 2 parts - rear rib and nose rib riveted together.

3) In the plans, the rear elevator skins are made of 1 part that wraps around the trailing edge. This is too complicated

    and time consuming. I will split that part in…

Zenith aircraft at Air Venture and Jon's Fly-In on Saturday before the show

First, if you missed Sebastien and Roger's news presentation, here it is again.  Very nice video.

My airplane will be at a display next to Zenith as always.  I made some personal changes with my friend Vern to the airplane.  Come have a look.  Right now it is being wired for some new fuel pumps.…

Six Years In

Today is the 6 year anniversary of opening up the rudder box in my living room and drilling the first hole. Even though I only get to work on weekends, and on weekends outside of the summer when it isn't 110+, I had kinda thought I'd be done by now. But if I've learned one thing on this project is to take all estimates and double them: and expect it to take longer than that.

While we are firmly in the 110s, I have managed to sneak some early mornings in this summer in an…

CH701sp Flight testing - 93 hours since September 28th,2012

Sunday July 17th, 2016 (93 hour TTSN)

Hi All,

It's been a long time since I posted something new in this flying log. So, here it is.

Since last year, I've flown another 8 hours. Weather and other obligations kept me grounded but no more.

The 701sp is still flying well; engine, prop and airframe are all doing good. I had to change a small brake line piece (between the dual caliper disk brake) and it was a half day job. It leaked again and I will…

Nose Gear Bottom Bearing Fabrication

I completed most of the fabrication of the nose gear bottom bearing. This was a fun little machining project.

It gave me a chance to make use of the boring head for machining the hole for the nose gear leg and the sine vise for accurately cutting the angles.

Almost finished result.…

The 2016 West Coast Zenith Fly In Report

The inaugural year of the West Coast Zenith Fly - In is now in the books, and it was a success.

This event was held in Arlington, WA during the annual (and great) Arlington Fly In.

Despite very threatening weather, we had seven zeniths show.

A 750, a 601, an 801, and four 701s. Two of the planes were from California!

We also had about a dozen active builders join us, which may be the most rewarding part of any fly in. Ideas and tips…

Current status

I decided to change the WW front starter, flywheel, John Deere alternator, and harmonic balance for rear mounted stuff to not have interference with my plenum ducting and to fit a new cowling.  So I will have the above stuff for sale. Also a SPA metal cowling with carb heat. New, never mounted and very nice.

Bubble Doors

I am replacing my first generation bubble doors with tube supports on my 701 with second generation bubble doors with fiberglass support for the acrylic .  Does anyone out there have any experience with this?  Will I have to alter the sill height?  Will the hardware transfer to the new door?

Thanks, Vann

Landing light installation

Does anybody know the best way to cut the hole in the slat (of a 750 stol) for the landing light.

Thanks in advance for any ideas?

Looking for some consultation

Say folks... wondering if there is anyone within reasonable distance in and around the Austin Texas area willing (and interested) in getting together to share ideas and builders support?  I am well into my Ch701.. but.. the more technical aspects are challenging, i.e., bending aluminum skins to form elevator.. wings, etc... I would like to get things right the first time around..

Starting to cleco firewall

After making lots of parts and remaking a few, I finally get to start drilling and clecoing the firewall together.

I mounted the firewall onto 80/20 stock with extra steel angle and magnets so I can work on it standing up.

The 80/20 is connected with hinges, so I can tilt the firewall back  to allow continued loose fit up

to the rest of the fuselage.

The fuselage can be seen behind and is similarly supported with 80/20,steel angle and magnets. .…

Drilled and cleco'd rear fuselage to cabin today. Center line and level and 74° angle side channels are great!  Wondering why the next step is the  instrument panel. A lot of work is still needed at bottom  connection of rear fuselage and cabin. I known not to do anything at strut location yet. Will follow photo guide but I noticed there is a lot of self interpretation  between photo guide and construction drawings.
