    Yesterday, Klaus Truemper wrote " . . . . since cabin pressure is always less than outside pressure." In my 601HD, there is a 1/4" gap between the lower edge of the canopy and the upper longeron. In flight, why is my shirt sleeve always sucked out through the gap (left or right side)? John Goodings, C-FGPJ, CH601HD with R912S, Toronto/Ottawa/Carp.

    Subject: Re: False airspeed indication on 701
    Hi John, The pressure differential you mention at the canopy/longeron gap is due to the fact that there is VERY low pressure above the wing. So indeed, pressure over the wing is lower than cockpit pressure. One time, that gap tried to "eat" my sectional! What I meant is atmospheric pressure, which the static port(s) attempt to capture. That pressure is higher than cockpit pressure.

    Subject: Re: Rotax 912 fuel pump
    Hi John,* *1. Any decent metal automotive fuel filter will do. 2. According to the Rotax manual, max pressure of the backup pump should not exceed 5.8 psi. A good choice is the Facet pump #4015. Aircraft Spruce offers this pump. There is also another Facet pump that goes up to 6 psi. Do NOT install that pump since it exceeds the Rotax psi limit. 3. We mounted the Facet pump on the firewall downstream from and a bit higher than the gascolator. 4. Our gascolator is just an aluminum box with a quick drain. It was part of the kit and does not have a screen. 5. Our arrangement is as follows: gascolator -> filter -> Facet pump -> Rotax pump There are other arrangements possible. Some aspects were covered earlier (series versus parallel). 6. A backup pump can be a grief- or even life-saver.

    Subject: rivedrill
    Hello, all I have a question for rivedrill users: have you been using the tool for A4 rivets? If so, how? I ask because the smallest head they had at the time I bought it (five years ago or more) was too big for the A4 - I use it for A5s. Thanks in advance Carlos CH601-HD, plans Assembly of left wing to start soon

    Carlos. I pulled nearly all the rivets in my 601XL with a Rivedrill. When I was at that stage, I kept two of them, chucked into different drills, one for A4s and another for A5s. I had no problem with either size. I ground the dome shape in the nose pieces myself.

    Subject: CH601HD brake lines
    Can anyone give advise on routing brakes lines and what to use on my 601HD. I am at the point of closing the wing center section top skins. I am thinking about using 1/8" aluminum tubing and going through the daylight lower corners of the rear ribs just behind the main spar. I just don't see a good neat way to route between the gear and the pedals. Does anyone have any suggestions? Thanks, Michael French

    Hey Carlos, There is a CAF museum in Burnet which is about 50 miles from Austin. www.highlandlakessquadron.com/museum.html Austin is a great town. Have fun! Dave Clay Temple, TX Read this topic online here: http://forums.matronics.com/viewtopic.php?p=184610#184610
