    Subject: Engine and Fuel Flow Monitor for 912 S
    --> Zenith-List message posted by: "Phil & Michele Miller" <millerpg@ps.gen.nz> Hi, Sunny, Have a look at Skydat instruments http://users.iafrica.com/a/am/amptro/. Thay are a South African company with a good product (forget the GX1 and, go for the GX2). I emailed them once and they didn't reply but they have an excellent agent in Australia who is very switched on (he even replied to my email query on Christmas Day!!!) and sells almost anywhere in the world. His name is Michael Coates and his web site is http://www.mcp.com.au/xair/skydat/skydat.html. The GX1 and GX2 have a digital display but with analogue representation for the major functions. Regards, Phil Miller New Zealand 701 912S (with Skydat GX1) >I'm getting a 601 DX (German Version of XL) with a 912S Engine. I'm interested in getting a good (light and accurate)Monitor to watch the following functions: EGTs Maybe CHTs using a ring sensor Coolant temp Oil temp pressure OAT RPM Manifold Pressure Fuel Flow (with GPS connection) I looked at the EDM 800 from JPInstruments, it does all that(and much more ofcourse) but if I want to use it as a primary instrument for RPM + MAP, would rather have them as analoge display. Anybody with any suggestions? Sunny _

    --> Zenith-List message posted by: "Pradeep Datta" <p.datta@tastomat.de> Hi Phil, thanks for the tip. Unfortunately Instruments seem to be having only 2 X EGTs ...or am I missing something? 2 X CHTs is fine but EGTs really should all be there, no? I forgot to mention in my previous post, a data logging system should be in it too, somthing which collects data every afew seconds or whatever, and then the last 20 hrs of flight data can be downloaded to a PC or Palm or whatever.

The Skydat seems to be having only 2 X EGT and the Rocky Mountain stuff doesn't have Analoge RPM and MAN :-( Oh boy, tough situation.... but any more ideas? rgds, Sunny On Wed, 29 Jan 2003 17:17:24 -0500, David Tellet wrote: >--> Zenith-List message posted by: "David Tellet" <telletdl@erols.com> > >Try here for an assortment of monitors and electronic flight data: > >http://www.sportflyingshop.com/ > > >And here for monitors and encoders > >http://www.rkymtn.com/

    Subject: Rotax 912 interference with new starter
    --> Zenith-List message posted by: "duba" <duba@gate.net> Just a quick note about anyone purchasing 912UL/ULS. There is some question about a new starter which Rotax is offering and interference with the motor mount on CH701s. No definitive answer but be cautious prior to buying power plant. In our experience there is no need for heavier starter even in cold weather operation.

    Subject: Re: Engine and Fuel Flow Monitor for 912 S
    --> Zenith-List message posted by: "Pradeep Datta" <p.datta@tastomat.de> I had a look at it, they don't seem to be having analoge display for RPM and MAN. The problem ist that here in Germany, the 601 DX (german version of XL) is classified as UltraLight with MTOW of 450 Kg (isn't that 990 Lbs?). So, I have to really cut down on having too much stuff on board. Good to have RPM and MAN as analoge display due to trend and tendency etc. So that's a must.

I'm in the Frankfurt area; the plane (Ch 601 HDS) is still in Luebeck - looking for a new home for her in the Frankfurt area. Anyway, I'm using the Grand Rapid EIS system. No big bucks, but reliable and good. Additionally, I have an analoge tacho installed. However, I fnd myself looking only at the EIS... ----- Original Message ----- From: "Pradeep Datta" <p.datta@tastomat.de> Subject: Re: Zenith-List: Engine and Fuel Flow Monitor for 912 S > --> Zenith-List message posted by: "Pradeep Datta" <p.datta@tastomat.de> > > I had a look at it, they don't seem to be having analoge display for RPM and MAN. > The problem ist that here in Germany, the 601 DX (german version of XL) is classified as UltraLight with MTOW of 450 Kg (isn't > that 990 Lbs?). > So, I have to really cut down on having too much stuff on board.

    Subject: RE: 601XL fuel system
    --> Zenith-List message posted by: "nhulin" <nhulin@hotmail.com> I'm going to go against the flow on this one (pun intended). I had our local Chapter Tech Councilors over last week and while discussing my 601XL main/aux tank setup I asked "What about a Piper Cherokee? It obviously doesn't have a downhill run from the tanks to the gascolator due to the position of the fuel selector." Their answer was that it relies on the fuel to push the contaminants (water) through to the gascolator. This lead me to start thinking in more detail about how I'd been taught (and always practiced) the preflight on the Cherokee. Hmmm, so I dug my old Piper Cadet manual out of the bookcase and went to the chapter on the fuel system. Sure enough you are advised in Chapter 8, paragraph 21, section (d) as follows: "Each of the fuel tank sumps should be drained first. Then the fuel strainer should be drained twice, once with the fuel selector on each tank. Each time fuel is drained, sufficient fuel should be allowed to flow to ensure the removal of contaminants." So, do you really need to have a downhill run all the way from the tank to the gascolator? Ideally, yes. In practice, perhaps not. As long as you can reliably get the contaminants out of the line, or leave such a small amount that the gascolator can prevent any residual contaminants from getting downstream, then you have a serviceable fuel system. How lucky do you feel? I'll install mine with a downhill run all the way from the tanks to the gascolator. I'm still planning on teeing together the I/B pair and the O/B pair and then using a four port selector from a Van's RV with one port blocked off (off, I/B, O/B, unused). I spoke to Nick Heintz earlier this week about the four tank system. He said that there would be an updated drawing, 6-W-13A, available some time next month (Feb) and that they'd be on the web site. Maybe you should wait until you see the revised system details. Which ever way you do it you probably need to add the correct procedure to your preflight to ensure each line from each tank is cleared correctly in the same manner as the Piper. ...neil Neil Hulin 601XL - doing wings and fuel system
