Seems to be lots of you going to floats. Thought I would share a very simple
holder to secure the paddle handle. Came up with this after trying many
different "manufactured" clips that all hold the paddle up too high and
allow the air to catch and pull at the paddle.

I have uploaded 2 pictures to the site files. Ones shows the paddle secured,
the other with the holder open. Very simple to build, takes about 5 minutes
and it's installed. Simply take a piece of aluminum or stainless tube with
an inside diameter equal to the paddle handle. Cut a slice about 1 1/4" wide
and then cut it in half to form two "C" shaped pieces. Take about 4 inches
of "male" and "female Velcro and stick them together, back to back. Drill
the tube piece for 2 rivets and put matching holes through the Velcro. Rivet
the tube and Velcro to the float.

We have had a very similar Velcro holder on Howard's floats for 3 full
summers, with his aircraft outside on his "dry" dock (Howard lifts his
aircraft out of the water, on a platform with air tanks under it, so boat
traffic doesn't pound it against the dock) from June to October each year,
and his Velcro is still holding fine.

Mount your paddle blade with an aluminum holder that won't allow it to slip
through it and then have your handle head so it butts against a spreader bar
or a piece of angle as a stop. This way the paddle can't blow loose in
flight as it can't move forward or backwards as long as it's secured.

Hopefully you never need the paddle anyways!

Wayne, can you please tell me how to fix my sight guAGES? I have put a
restrictor in the bottom el of the tube and it's better, but when I get to
about 5 gals a side the gas dissappears from the guages and it looks like I
have no fuel. Is there A fix to keep the guages more accurate?
Thanks....Brian

Brian, Stop flying with less than 5 gallons of fuel in each tank! Then you
will not get as nervous!!!

Seriously, you must have the site gauge in MAM's newer (ridiculous) straight
up/down position on the front end of the fuel tank. I know this without
asking first, as 5 gallons US just wets the bottom of the tank at the filler
neck in the 3 point position, and even on amphibs the dip stick doesn't
change that much. You need the lower fitting, for the tube style sight
gauge, to be as far back on the tank as possible if you want it to be of any
use. I'm not interested in seeing max fuel, but I sure want to know when I'm
getting low!!! On any that I have been "refurbing", which includes removing
the sight gauge from the tee at the fuel outlet (as the original MAM
installation does draw air into the fuel line!!), I have been installing a
new tank fitting about 1 3/4" forward of the original outlet fitting. Only
drill a small hole at the lower edge of where the tank fitting will sit.
This gives you an automatic restricter hole to stop the sloshing around on
the sight tubes. Also this way you are only drilling about 6 #30 holes in
the finished tank so aluminum chips shouldn't be a problem in the tank. You
may be able to do this with the wings installed using an angle drill and a
hand riveter. The other possible cause, if you have the sight tube on a
slant like I have described, is I have seen installations where the tubing
from the tank through the fuselage root ran up hill. You need to make sure
that the tube is coming though level or downhill from the tank into the
cabin to show a fairly accurate amount at low fuel levels otherwise the tube
just drains back downhill into the tank when low on fuel.

Wayne, is there a way to redo the vent. Mine is cross vented and if I blow
into the hole the fuel gets blown out of the sight guages, so when I get low
it shows no fuel in the tanks. I have already put a restrictor in the BOTTOM
el of the sight guages and was wondering if there was something else I could
do to stop the pressure on the guage...Thanks....Brian

Brian, I feel this happens due to the restrictions at fittings going into
the tanks. Even though minute, this means that there is more ram air
pressure on the top of the sight gauges, than the pressure value that makes
it into the tank itself. This obviously means that the fuel level will go
down in the sight gauge as there is a higher pressure at the top, than the
port at the bottom from the tank.

On Bob's "XWI" the ram air tubes are on the fuel caps and I don't remember
the sight gauges being effected that much, as compared to the amphib I sold
that had the ram air in the cross vent. It seemed to work quite accurately
because now the opposite would apply. More pressure in the tank, than at the
top of the sight gauge tube that would help hold the fuel level in the
correct place. Please BOB correct me if you are observing something
different in the 125 hours or so (MUST BE NICE!) of flying since XWI left
here just over a year ago, but that is what I remember.

My personal Rebel's ram air is ala Cessna, from behind the right wing strut,
but I have float senders so can't tell you if this would help the sight
gauges (although I imagine it would, but isn't an after the wings done
option!)
