They provided a pitot and static port unit which I believe is standard on the 601. I'm not sure how accurate the static port position is since I'm not flying yet. This isn't a great photo. If you need others, let me know and I'll snap a few more next time I'm at the hangar.

Nice night last night so took N701ND off the ground for the first time. Flew pretty well flawlessly, although like an engine running "automatic rough" over water I kept thinking I would hear various strange noises from all parts of the fusealge and engine!

I pretty well followed JG's and the EAA's advice for test flying on the first flight from his website and private e-mails (thanks JG!) went up to about 4000 AGL and tried various airspeeds to "tickle the stall" and see how it handled at landing speeds and simulated approaches. Yawn - pretty docile.... Set up a nice long stabilized final and as JG had instructed me via e-mail, crossed the fence at about 50mph and 3000 rpm, then cut back the power almost on the grass. The only thing I did wrong was when I cut the power a foot or so above the grass I flared a bit too much and ballooned a bit so added a hair of power to "not get on the backside of the power curve" then touched down smoothly! Wow that elevator/pitch is sensitive! More than I'm used to than in my VG'd Kitfox. All in all a pretty non eventful flight except for overrevving a bit on clibout before I noticed it! I plan to get used to it with slats, then try VG's and slats removed later on.

From: "n85ae" My guess is due to slight differences in vents, and lacking a line to balance pressure between tanks this is the real culprit. In Kitfoxes this is very common, the reason for it is the header vent line returns to only one tank. This causes a a pressure differential inside the two tanks. The only real solution is to put a balance line between the two tanks to balance the internal pressure. All it takes is a slight pressure difference between tanks to cause this to happen. The plus is that at some point when one tanks gets lower in fuel than the other the fuel flow will equalize. But with one tank having lower quantity that the other. It's a good reason to use a header as well. Because regardless how the fuel from the tanks is flowing to the header, the feed to the engine is constant.

From: "Roland Smith" Plumbing in my 701 ( N701AA reserved) is for one tank at a time. Never both on. This has worked well in my old Taylorcraft BC12D, albeit, with a header tank and also with my Cessna 140 that I fly to stay current while finishing the 701. This serves me best for fuel management. For example: Should my engine splutter when the fuel in my left tank runs dry I know there is fuel in the right tank. My preflight dipsticks are calibrated for each tank. I also marked the gages at one hour remaining. If anyone sees a problem with this setup for the 701, please comment. -------- 701 kit, Rotax 912 ULS, SensorNetics EFIS, working on Skyshop FWF.

Jeff, If the problem is due to slight differences in vents then why would some be able to duplicate this with ground tests? I'll try to attach a page from a 1981 C152 POH. Note that there is a vent line between the two tanks. This might be hard to do in a CH701 as the fuselage dips between the wings and I don't think you would want that vent line to have a dip and fill with fuel. Also note that the exterior vent line is on the left tank and the left tank has a sealed cap. The right tank has no exterior vent line but has a vented cap. It also looks like there is an ON/OFF valve (no LEFT/RIGHT/BOTH/OFF). I've never flown a C152. Does anyone know if the C152 has this problem?

First I put it inside in the wing above the pitot tube. At high angles of attack, the airspeed read way low, probably because air was being forced into the root of the wing in this attitude. It was uncomfortable landing with an indicated airspeed near zero, so I just disconnected the static air line under the panel, but it still read a little low at high attack angles. Then I put the static air intake on both sides under the doors. This was a little better, but still about 5-mph low at slow speeds. Finally I moved about a foot behind the doors and am getting good readings. Guess I should have asked the guys on this list beforehand as you are doing Tracy.
