Product Reviews

We're tying something new at, a Product Review site that will allow builders to share their actual experience with a specific instrument, system or new idea that has been implemented.

An example would be Dynon's EFIS-D6. A blog will be posted and using Dynon's descripton of the specific product. Those of you that have actually used the system can post your comments. Pros and cons, hours used, airplane that it is installed, price and would you…

Kitplanes magazine article on the safety of Zeniths: "Safety is no accident"

The November 2010 issue of Kitplanes magazine (and it's still September as I write this!) has a story on the safety of Zeniths, presented as part of a series of articles on homebuilt (kit) aircraft safety. As the article's clichéd title states, safety is no accident, so I'm reprinting it here (with the gracious permission of… Continue

N number now in the FAA database

I don't know why this should make me feel elated, since this is hardly critical at this point in time. Somehow, though, it seems like a rite of passage of some sort. Hopefully, N274AJ will be in test sometime next year!

Maybe it's encouraging, since the rest of the day has been full of bent or broken parts. :)

Started marking out

Finally bit the bullet and started. Drew up curvy bits such as wing, stabilizer and rudder ribs on CAD. Printed them out 1:1 scale and traced them on to the 6061-T6. Only done the 0.016" bits so far (oh and the 0.025" spar webs), but it was good to finally get some aluminium out and start work.

Question now is what the best tool is for long cuts. 300mm shears? Nibbler? I know for damn sure I won't be making 12 foot cuts with aviation snips!…

It's a bird it's a plane, another Zodiac 601XL leaving the ground

After many obstacles, 417SX departed U76 this afternoon, I should have

waited until tomorrow morning, it was warm today, 91. I decided to do a

high speed taxi to see if the Airspeed Indicator was alive, it was, and

figured that a short flight to test my FWF had come. Taxied back and I

was airborne quickly, remembered to keep the nose down in a cruise

climb, 500 fpm, Airspeed was indicating 120mph and the GPS was giving a

similar reading with the engine turning at… Continue

Fix Rudder or Rebuild....

My rudder is twisted, somewhere along the line it wasn't flat on the beams (in fact the beams themselves weren't flat - see my forum post) and so the final product won't lay flat.

Zentih think the twist is in the bottom ribs so I will start at the bottom and drill out upwards until it lies flat. Depending how far I get I will re-rivet. Or I will get another kit. Coming with no experience of any of the tools and techniques needed for this endeavour, I've learned so much and if this… Continue

Get Well Soon to CH750 Builder Clay Hollenback...

Clay Hollenback ( underwent surgery this week, and is not able to work on his CH750 for a up to eight weeks. I am sure that he could do with some get well messages - since he is probably feeling sorry himself, sitting there holding a handful of rivets, gazing out of the window, begging his family to purchase a flying magazine from the local store....

Clay is a great…

Test Pilot or Moron, there is a fine line.

Living on a lake has it advantages. I have cut a ramp on my front lawn down to the lake so that I can get my 701 amphib up and down since my hanger is up on the flats off my driveway. The grade of the ramp is about 7% and it is about 80 feet long. As you can see in the picture, to overcome this grade I have set up a winch in the back of my hangar and using a remote control I can activate the winch all the way down to the shoreline.…

Zenith's 19th annual Open Hangar Day - Follow Up Report

I've already had many of you ask how our Open Hangar Day activities went, so here's my "official summary report" along with some photos. Above is Ulis Temos with his STOL CH 701 which he flew in from Pennsylvannia, with Rotax expert Dean Vogal (squatting).

We started the activities on Friday afternoon following our monthly hands-on "rudder assembly workshop" class and a hotdog & soda lunch… Continue

band saw?

I am having trouble cutting brackets for my tail section using my horizontal band saw. Pieces are too short for saw and angles too great for rotating table. What have you used that gave precise angled cuts?

Being 'On Top' in a 701

Flying VFR is wonderful, we get to see the real world, and we get to enjoy sights that make us smile. When I get asked why I never pursued a career as an airline pilot I have a simple response 'why be a bus driver when you can be a racing car driver!'

I know that the speeds of our aircraft are often around 20% of that of the big birds, but our pleasure and grin factors are much greater thanks to the environment in which we fly - and we do fly - hands on, looking out the…

CH701 Cable tensions

I understand from Matronics list that the rudder and elevator cable tensions are: 305 and 205 respectively. Can anyone please tell me in what units these are measured?

Finished wings

I finished my other wing and am wondering if I am about on track in the building process. I have completed both wings, rudder, elev. & stab, I have about 250 hrs. const. time so far. Am I ahead, behind, or about average?

Showing the flag at Farmerville, LA Fly-in

This morning I found that my dad and I were internet stars in a video montage from this weekend's EAA fly-in at Farmerville, LA (Union Parish Airport / F87). Trying to evade as much of the heat as possible, we flew up there early and were the first arrival so the Papa Goose got video coverage at the fuel pump right at the beginning of the video.

We had to bug out before the P-51 arrived but we did get to see the low pass by the Air Tractor crop duster, complete with airshow…

Successful First Flight N8701W CH701

Yesterday morning weather was good so made the first flight with my 701. I had never flown a 701 before or a plane with a joystick. The angle of attack at take off surprised me a little so the take off was a little sloppy. Flew for 45 minutes remaining over the Rushville IL airport. All temps stayed in the green and everything was looking good. I had to make some adjustments on the flaperons, when I landed, because I had to hold the stick pretty hard to the right to maintain a level flight… Continue
