Why is the rubber disc cut?

Jan,I often get questions about why the rubber disc is cut, and I suspect other builders do as well. Most question why anyone would cut up a disc that was not designed to be cut up. Seems like a…Continue

Fuel Design: Risk of sucking air from one tank while in a steep turn
There are several solutions to prevent a fuel system from sucking air from a fuel tank while in a steep turn when the fuel level is low. This has been a hot debate on other forums.I am curious to hear from folks who are actually flying their planes on which design you use to address this risk. 1) Header tanks?2) Check valves?3) Limit fuel selector valve to only use R or L tank but not both?4) None, I use "both" on my selector valve and do not have a header tank and have not had any…See More

using leaded fuel with O2 sensor
While this is not necessarily unique to Viking engines I thought it would be as good a place as any of the forums to ask the following questions.Since most newer automotive engine systems use O2 sensors and knowing that leaded fuel fouls O2 sensors, (given that we will occasionally have to use leaded fuel) I would be curious to know:1) How long (hours) before the O2 sensor goes bad?2) What are the signs that the sensor is going bad?3) Is you experience based on the narrow band sensor or the…See More

I appreciate your comment, I attempt to document this unique experience as a novice builder and I continually learn from my mistakes and from others. I have only been at it since first Zenith class in 10/16. But it truly is educational, recreational and of course humbling. My EAA tech advisor told me that at least it keeps him out of the tavern.

Charlie, I accidentally clicked the ignore button on your message. I think I added you now though.
Anyways, I helped with the 750 STOL build but not the Cruzer so I dont think I can weigh in on that part! Feel free to email me at kvoltz@eaa.org

It wasn't bad, I filled out the appropriate paperwork and submitted it and it went pretty smooth from there. They look at the coordinates and verify that it wont be a navigation hazard to other airports and such. The only issue I did have was with the lady who made the initial contact via phone, she obviously didn't want to deal with it. I used the garmin in the plane for the lat long coordinates and she was pretty rude about that, wasn't acceptable to her and pretty much called me a dumbass. She changed the numbers to what she said they should be, rounded them off, and now the field shows up across the river a few hundred yards away but its no big deal. I still have the forms and paperwork so when you get ready I'll dig them out so you'll know what you need.

- Thanks Charlie, it was a great trip through the mountains to the west coast. I am planning a longer trip for this spring...from Ottawa, across to Calgary then up to the Yukon. ( about 8000 miles). The ch 750 is a great aircraft for its mission but certainly 'takes its time' for longer adventures. Conrad

- Charlie, re warp drive prop.
It has been up to expectation. I am using it with a Rotax 912. I had it tested for balance and found it to be too exact to warrant adjusting. The nickle leading edge is good. It is ground adjustable.
I have never had any problems with it.

Hello Charlie; i put a deposit down last year during Sun n Fun prior to the engines being ready, since then my work has been crazy busy so i have been pushing the delivery date back. I hope to have the airframe ready for engine mount by mid summer.
as for availability, Samantha at Viking has kept me updated on the progress, i think the only thing missing is a propeller to handle the 200 hp, and Jan is testing a different brand as we speak!
