Twin Zenith CH 750 Aircraft Get Their Airworthiness Certificates

Today N750HB AND N750MN got their certificates of airworthiness. It was just a little over a year to put them together, working part time.

It's been a while since we have heard from you guys. Hopefully that means you have been busy flying. I am getting close to engine decision time and would be very interested to hear what your experience with UL has been like. How long was the order lead time? How did the installation proceed? Performance has been good by the sounds of it, prop and engine combination Good? Were there any major bugs or issues? Sorry, these questions seem a little wide ranging, really I'm just trying to get a feel for how the process went for you two, as I am sure there are several builders out there who are curious.

Rpm so far has been 2900 to 3000. EGT has been running 1340 to 1425.

What is your RPM on takeoff and highest EGT after one minute at full power?

So far I am very well pleased. I only have 6 hours on it, bot it takes off like a rocket and temperature are good so far. After a few more hours I will be able to post some numbers. Yesterday I was flying at 2650 rpm and doing 95 mph. Oil temp was running about 200 degrees. I did put my baffeling on the inside of the baffles, so we will see how that works out. I have made 6 take offs so far and one I was off in less than 100 feet.

Hi Dick

Like several other builders, I'm extremely curious how you are making out with the ul 350 and the props you have chosen. You have had the planes for a couple weeks.  What are your first and second impressions?

This is unbelievable....both planes came out at 798 lbs.

Great stuff.
I am curious how much your planes came out weighing?

After you have 100 hours on the engine, drop us a post and let us all know anything you have learned from using them.
