Just a little beefier, I don't know about the standard 1232 lb design, never seen
one. But the upgraded ones have doublers. Just have to find out if they started
like the 1100lb CH or the 960lb CH.
What is a 3X gun?

Subject: | Re: 701 fuel system design |
Dave,
Answering your questions:
I don't think there are problems removing the wings with selectors inside
the cockpit at the wing root. Just disconnect the lines to the wings at that
point. Having said this I need to add that I have never disconnected them
and would not recommend this if you plan to remove the wings a lot unless
you put some type of quick disconnect as opposed to just pushing the lines
onto a nipple.
It would be difficult sending pics of my installation. I ran the lines
inside the cockpit from the two selectors down along the steel cage on
either side of the windshield, through the firewall and to a single
gascolator at the lowest point on the firewall. This is the lowest point in
the fuel system and the lines run downhill from the tanks so that water
could not collect anywhere else than the gascolator. From there I ran the
fuel lines up through a fuel flow meter and an aux electric pump (which I
have never had to use) to the engine. I was concerned that putting the
gascolator forward of the firewall could lead to vapor locks.. Not so; I
have 250 flight hours, some of it in 105+ air temps without any problems.

If I has only a single tank in each wing I would use the same setup with an
on-off selector switch on each wing root. Simple and safe.

I am installing Aux. tanks also and that is my idea also "selectors at
wing root Main/Aux/off" then to the normal gascolator and to a firewall
shutoff. My question for you is what selectors did u use and can u share
pics of your instlation?
Also is there any problem with the selectors at the wing root and removing
the wing?
Thanks Dave

Fellow 701 Builders:
I am currently searching for the best prices on the Garmin GTX 330
transponder and SL 40 radio. Aircraft Spruce lists the former at
$3,621 and the latter at $1650. I am wondering if there is anywhere
they can be purchased at a lower price?
I recognize that there are less expensive alternatives but the traffic
information the 330 provides to the GRT Sport EFIS seems a wise
choice given the difficulty in seeing a polished aircraft.
I live in the Denver area.

Well, a bug nut that butts against the end of the throttle cable housing
as a throttle stop is working well for me. That eliminates the only
problem I have found with this cable setup, other than the springs and
maybe I will learn to live with that. Initially, it was easy to pull the
throttle beyond the intended idle with just the stops at the carbs.
There hasn't been any sync creep with this setup so far, it's still nice
and smooth. Time will tell if it is the ultimate solution, so far it
looks promising...

Gary,
If you don=92t want to get nervous about your =93trusty=94 electric
needles to
determine fuel availability, consider a fuel flow measuring system. The
fuel
flow sensor added about $100 to the cost of my Dynon engine monitoring.
When I fill up now I rarely have to add over a quarter-gallon more or
less
than the Dynon tells me that I have used.
Also, we have discussed the uneven draw from the tanks in earlier
threads. I
always fly with both inner tanks or both outer tanks open so that I
can=92t
forget to switch tanks. My tanks may drain unevenly because my autopilot
uses the ailerons to steer the plane, which means the wings are not
always
level. Frankly I won=92t worry about this unless I=92m low on fuel
because if
one tank empties the plane should just draw from the other one. However,
I
have never been really low on fuel and the tanks have never had more
than a
4-gallon difference to see what would happen.

Hello Dan,
I installed the same (one valve in each side of the cabin). My 701 with
only the main valve (floor valve), will always use first the gasoline
from
the right wing. No problem in short flights (less than an hour), when
the
plane is parked both tanks will even in a few minutes.
In long XCountry flights (more than 2.5 hrs a leg) this has worked for
me:
Take off with both side valves open, for security, at cruise altitude I
close the right tank for one hour (in use the left tank), at one hour, I
open the right valve (keep both valves opened for the rest of the
flight)
and when landing I always land with both tanks (almost) even.
For "Simplicity and lightness" I should only add the right wing valve,
left
one never closed for balance fuel.
I always plan my flights for less than 3 hrs a leg... I get a little
nervous
when the "trusty" electric needles get close to 1/4... :-) :-)
Here there are only a few landing strips, less with gasoline available.
Saludos

I just installed valves at each wing root inside the cockpit. I can
easily reach each valve and use it to balance fuel use between tanks. I
added a note in my preflight checklist to make sure all fuel valves are
on for takeoff.

incidents as well as commerical aviation. I'm trying to reduce other
fuel

fuel
starvation. My thinking on the two fuel selectors at the wing roots is
it's
very visable (I.E.unlike John Denver's) and easy to get at.
