Hi everyone,
Has anyone switched to a pneumatic tailwheel?
If so which one did you go with?
Does anyone know what Murphy recommends?
I am looking at the options in Spruce.
The maule tailwheels are less expensive than the
Scott tailwheels, so I am wondering if the quality is
that much less with the maules, or am I ok going
with a Maule tailwheel? They are on page 217 in
the Spruce catalog, if anyone is interested in looking
at them.
Thanks for the advice,
Shira Ellsworth

100 degree worked fine for me as well. However, I flush riveted the

entire

aircraft so I likely used my tool more frequently than most. However, the
wing stringers I bucked with AN rivets and wherever it was easy access I

put

in AN rivets with a squeezer. I also did some testing of pull away

strength.

This is the force required to lift the skin off a surface along the axis

of

the rivet shaft. The AN rivets were slightly stronger and the failure

mode

was the skin would rip before the rivet failed. I was not able to test

them

in a shear mode (90 degrees to the axis of the rivet), my scale wouldn't

go

high enough for such testing.

I just used the 100 degree, they seemed to pull
in just fine. I thought this
had been discussed before but couldn't find
anything either. Anybody else
just use the 100?

Hi everyone!

Searched the archives, but couldn't find the
answer. I've got 100 degree
countersinks and dimple tools. I've been told
the Avex CS rivets are 120
degree. Can I use the tools I've got, or do I
need new stuff? If I need 120
stuff, where can I buy it?

Thanks,

Hi Shira !

If your Rebel will be heavier ( using an O-320, or even an
O-235 ...), you will find going pneumatic will give a much better
ride and be easier on the airframe.

Go with the Scott 3200 (or a 2200, if you find one cheap !),
the Maules are cheaper for a reason !! I've flown both on different
aircraft - the Maule only has one side arm, and they tend to shimmy
badly when they get a bit worn.

The Scott 3200 is a popular choice with O-320's, because it
adds about 8 lb. right on the tail, which really helps the C of G !! :-)

Just my 2 cents .....

Shira,

I know the price of the Maule tail wheel is tempting but I would never own a Maule tail wheel again. I am not alone in this recommendation as many pilots with more time and experience will attest to the same.

Maule tail wheels are a ground loop hazard waiting to happen. IMHO.

Thanks Bob and Bruce for the advice,
looks like I'll go with the Scott 3200 since
I have an 0-320.
