 Posted: Fri Jan 18, 2008 5:51 pm Post subject: N701ZZ 1st flight (Jab 3300 w/retractable slats) |
 |
|
N701ZZ flew for 1 hour today. Weather was 59F, winds were light &
variable, and not a cloud in the sky. Configuration: Empty weight
of 698 lbs, 285 lbs of pilot & fuel for a total of 983 lbs. This
plane has extruded struts, and strut fairings. A 701 with Pegastol
wings has a max gross weight of 1200 lbs. You may see pictures of
"Buzz" if you wish by clicking on the link below:
http://www.flickr.com/photos/22918119(at)N08/
I believe this is the only Ch 701 with a 6 cylinder, 120hp, Jabiru
3300 engine and retractable slats (PegaStol wings). I previously
owned a 701 with an 80 hp, Jabiru 2200 engine, built by Charles
Mulloy. I had flow it approx 100 hours so have some knowledge of
the differences in flight characteristics.
Overall, it flew beautifully; temps in range, fairly in rig, quite
and smooth engine. However, I will need to change the prop to more
of a climb prop. Max RPM on the 3300 is 3300 RPM. My max takeoff
and full power is a max of 2750 rpm so am not developing max Hp but
rather approx 105 hp or so if I read the charts correctly. One thing
that was noticeably different; this plane is VERY FAST! I climbed
at 90-mph TAS at 750'. I leveled off at 2700' elevation, slats
retracted, 2500 rpm with a TAS of 106-mph, fuel flow of 5.1 gal/
hr. When I momentarily advanced full throttle to check max rpm,
it quickly jumped to 122-mph TAS.
I reduced the cruise rpm to 2300 to slow it down to 90-mph TAS at
2500' elevation. The fuel flow showed 3.69 gal/hr. The nose was
slightly high. I cross checked the speeds with my GPS, both
directions to double check my readings. Think they are pretty accurate.
On decent, with 1200 rpm, indicating 65-mph, the rate of decent was
approximately 700 ft/mim. Slats came out gently and in small
increments as I started slowing. That was really a pretty sight.
The descent was definitely more gentle than Zenith wings, however,
the touchdown was a bit faster (not particularly a plus) but am not
familiar with the plane yet. I'l have a much better comparison after
the first 10 hours.
The max CHT for climb out for the 3300 is 392F (My max climb CHT was
343F)
The max CHT for continuous is 356F (My hottest cylinder, #5 stayed
around 320-330F depending on throttle setting)
The max 3300 oil temp is 244F (mine stayed around 180-190F)
I have a few issues to fix; plane turns left when flaps go beyond 20
degrees or so. Tach became intermittent on way back to field then
stabilized. Will probably change to other lead. #5 cylinder is
hottest so will adjust deflectors on top side of air shroud. etc.
etc. Just more fun.
These are preliminary findings (or impressions) so will update to
those wanting that information if they would email me personally,
off list.
This is the prototype 701 with a Jabiru 3300 from Jabiru USA. I want
to thank them, especially Pete & Dana for all their help.

Beautiful plane Jim!
Please do keep us posted, while I can't afford the Jab I still like to find out more about it.
I also like to idea of the Pegastol wings, but I don't know if they are worth (in my case) the extra time, weight and cost. But they sure are cool!

That has to be the sharpest looking 701 I've seen. The cowl really perks it
up and I like the way you subdued the angular bottom lines with paint.
Very, very nice.

I would be very happy to be able to see the 701, but sadly the link that is shown, does not work, and leads to an error message.

Hey Jim: Very nice. Too bad you didn't like yellow/black. I really like your performance numbers

Start the year off right. Easy ways to stay in shape in the new year.

Thank you and thanks to all who have commented on "Buzz".
I called Pete at Jabiru USA today to see if I could change my prop to a climb prop. My current prop os a 64/45. It's easy to blow right past VNe if I'm not careful. Within 5 minutes Pete had contacted Sensenich and has another prop, a 68/36 on it's way. My gear has been extended 4" so should have plenty of clearance. Am eager to see how this works out. Anyway, thanks again. Jim

By changing props, how much time is being added to the testing by the DAR?

If a prop change was a "major change" and my original 40 hours were flown off, then I would have to fly an additional 5 hours in my test area then if the test is satisfactory, I would sign it back into service. A prop change is not major and does not require additional hours to my understanding.

I know it varies from DAR to DAR. our guy up here has been know to require an additional 20 hours for a prop change.
