Hi Ralph, the build is going forward. but there is still a lot to be done. Fuselage still like you have seen it lately. Stabilizer, elevator and rudder finished. Wings are 90%, slats 50%. Flaperons still to be started. I attended an EAA workshop lately about the electrical stuff. Very interesting. I am drawing up schematics and I am also collecting the proper tools for installing the wiring. Still thinking about the engine. I still like the ULpower. I have been to Belgium, to the factory. Talked to the designer and found out I know the guy from my previous life in car racing.

How is your plane going? Flying to Ionia airport some day?

Hi Ralph,

We must have missed each other... were you at the dinner?

Will get footage into next DVD!

Hi Ralph, fuselage is on its wheels. Starts to look like a plane! I will do some stuff to the fuselage and start building the rudder then, elevator etc. I leave some parts open (top of fuselage still cleco'd; seats open, nose) for putting wiring in etc.

I see your fuselage is making good progress.

What are your thoughts on the engine?

Regards, Jan

Hi Ralph, I have vacation this week, because my children are over from the Netherlands. Thursday night my son and I will ride to Zenith, to pick up my kit.
I have time today-Thursday all day. Otherwise another day in the evening, or in the weekend. Please let me know what is convenient for you.
Regards, Jan

Hi Ralph, saw you on the DVD I got from HomebuiltHELP. I am living in Ionia Michigan (almost your neighbor). My wife and I were also at Sun-N-Fun this year and we could have met. This coming weekend I will collect my CH750 kit at the factory and start building soon. Could I have a look at your plane? I think it would be very interesting and helpful to me.
Best regards, Jan van 't Schip (just moved in from the Netherlands)

I bought a Shaviv deburring tool from Aircraft Spruce and it came today. Looks like it may be a good tool? I tried it on some scrap and it was pretty easy to use and did a nice job.

I used the half inch drill, but it didn't always do the trick. I find that sometimes one thing works and sometimes another?

I just saw your comment, thanks. Yes, I'm past that point in the tip rib attaching scheme and think I have an idea of what I'm going to do. I just finished deburring yesterday and really have to find a better tool than the drill bit idea. Tonight, I put on some corrosion proofing because I had scratched the inside skin with the file, so I wanted to protect myself. Tomorrow or Monday, I'll cleco it all back together and start riveting!

I'm at the same point you are in the process and am wondering when you deburred and riveted the spars and ribs? I'm at the point of putting on the Horizontal Stabilizer skin and saw no instructions in the manual for the above. It looks like, in the manual, that you put the skin on the top while the ribs and spars are still clecoed? Also, the instruction manual picture of the Tip Rib attachment to the L angle is different than my kit pieces? It is unclear how you align the Tip Ribs?
