engine monitor
Posted: Sat Feb 18, 2012 9:16 am
It only monitor's one cylinder (I'll have to look to see which one). As I recall, it was something about Brent commenting about monitoring the one that typically is the hottest. I agree that a 9-cylinder model is preferred; I'm going to be looking for such at Oshkosh.
I didn't check the frothing issue at my one intermediate fuel stop, as I was trying to beat an after-dark arrival in Iowa. I got in just after the sun set as it was. Had to use my hiking headlamp to see the switches and such after shutdown.
Here are prelim power #'s (I'll do a lot more experimenting in the coming days and report more to the list):
Indicated
Altitude Speed (knots) fuel (gph) Manifold RPM
13,500 82 18.2 17.6 1790
13,500 80 15 16 1710
3,500 83 17.1 20.1 1770
3,600 78 15.3 18.9 1770
3,500 85 16.5 20.1 1800
3,500 92 17.9 22.4 1800
3,500 98 18.7 23.9 1810
There's no way I'm seeing any RPM anywhere even remotely close to 2,900. Highest I've seen so far is something like 2150; I'll have one my passengers look at the RPM gauge at takeoff power tomorrow and report on maximum RPM then.

Have a good trip. It will be interesting to see if there is any truth to
the oil frothing stuff. Also curious when you get a chance what you like or
don't like about you engine instrument set up? Does it have egt and cht on
all 9? You have to manually switch between them right?? Also did he install
a carb temp probe?
Later,
Scott

I agree re the MAM tail swivel being, well, "cheap." I know we are in
the Experimental world, but, I think it's a little early in my
"experimental" career to be swapping parts from here and there to cobble
together a tailwheel. Perhaps if I talked to (or exchanged emails) with
a successful "swapper" then I'd feel better about venturing off.
Messing around with the tailwheel isn't something that I want to
necessarily take a chance on, given that a TW plane is already sometimes
a handful. That being said, any and all info you provide is much
appreciated.

You may have seen this one already, I took these pictures at Arlington
in 2003 MAM demonstrator. I believe it is the nose wheel fork off of
the Murphy Elite. I think Al Paxhia bought one for his Moose but I
think Murphy wants $800 to $1000 for it, I'll have to ask Al. It looks
like it just bolts to the current arms. The MAM tail swivel looks a
little cheapo to me, although I have not heard of one having any
problems yet.

I'd like to find a less expensive alternative to the XPMODS one, but,
just looking for such could prove to be a long science project. I
definitely don't want to fab one. I think the largest tire a Scott TW
supports is 10", but I have to look into that a bit more too.
Thanks for the pic. It looks like a 14" one.
