Tailwheel / prop clearance

[Ted Waltman]

Folks,

I have 18" clearnance at the prop's lowest point to the ground. I'd
like to purchase a larger tailwheel than the one that came with the
project. My concern is that every inch I raise the tail with a larger
tailwheel has to have at least a 2" or more drop in prop-ground
clearance.

In emailing back and forth to Tom at XPMODS.com, Tom (the owner and an
experienced bush pilot) says the following:
-----

"The comments that I get and with the testing we have done the prop
clearance is not an issue. First of all for the off airport operations
it would almost always be a rough soft or sandy to/landing area. The
small tail wheel would sink into the surface and create a significant
amount of power to un-stick it. This high power setting would be the
culprit in the prop picking up foreign objects. With the 14" (500x5) the
larger rolling radius simply allows the plane to be maneuvered with a
low power setting thus picking up a lot fewer nicks.

For the three point takeoff, angle of attack, the 14" out preformed the
10" or the 8" by allowing the tailgear spring to flex and the big tire
to roll on those soft fields too. The small tire would just dig in."

-----

What have other folks done or contemplated on the tailwheel?

Thanks!

Ted Waltman

18" is for a Moose, 92" Hartzell 3-blade prop, stopped on the ground
with the std MAM tailwheel. I'm just thinking of how the prop clearance
is reduced during takeoff (pushing the tail up a bit as one gets going)
and during any sort of a wheel landing. A hangar mate has a 185 with a
3-blade and his prop clearance was (I think) 24" (or more).

Thanks,

Ted

Ted,

Rebel or a Moose? 18" sounds like a lot even for a Moose. Did you
measure it
in a flight level attitude?

I have a Rebel 0320 with a Scott 3200 tailwheel and It handles very
well. I
never even unwrapped the MAM tailwheel form its plastic.

At least you don't have the 106-1/4" prop like me for the M462! Going to
require some BIG tires or gear leg extensions for wheel flying if I
complete going that route.

With the airplanes tail lifted into a level flight attitude, or slightly
nose down to cover wheel landings, you should have a minimum or 9" prop
tip clearance to be safe in a tail dragger.

To simulate a flat tire, park a main tire up on some boards that are the
matching thickness of the dimension from the ground to the bottom edge
of the wheel rim. Then lift the tail wheel up in the air in level flight
(or slightly nose down to simulate a wheel landing). This will then
simulate a flat tire if you measure from the prop tip in it's lowest
part of the arc and then subtract the full measurement of the boards.
MUST have a positive # to guarantee tip clearance.

Cheers,
Wayne

Hi Ted !

The factory had a 500 x 5 tailwheel on the factory demo
Moose - you might want to ask Robin, the chief pilot, about it -
they may well have them available for sale.

Certainly didn't seem to be a problem with prop clearance !

Also, I have emailed you offline, & re-sent twice now -
keeps getting rejected as "message delayed for too long - over
96 hours" !! Is there a problem with your ISP, or another
address I should use ??

Sounds like you've got the Moose, and are enjoying it already !

I would not recommend the XP on the Moose. I had one of Tom's original ones
on my 180 and 185 for 15 years. Those planes need the stab higher off the
ground (flying rocks) which the XP helps with about 4" more height above
ground. The stab on the Moose is plenty high even with the small tailwheel.
I flew the MAM demonstrator on both small and big tires (mains). Even with
the big tires and MAM's tailwheel I felt the need for longer gear to get off
the ground quicker. On the Cessna the 14" XP also inhibits rotation unless
also equipped with 29" tires. The XP is also hard on the airframe as it is a
larger twisting moment. Tom recommends glueing his wheel on the stinger with
JB Weld or the bolt holes elongate as mine did. I rarely swung the tail with
brakes but moved it by hand if possible after I broke my 7/8 stinger in
half. The stinger/tailspring attach point on the Moose is also a weak point
as MAM had cracks in the bulkhead. Oh, also the XP usually shimmies on
pavement unless you hold the tailwheel off as long as possible. It is great
for the 185 off airport however. Depends on what you will be doing with the
plane. Bushwheel has a new fat tailwheel setup also that I think would be
better for the Moose.
I do not think the long prop close to the ground is too big a deal as the
rpm is pretty low. The single Otter has the prop close to the dirt (also
geared radial engine) and never is an issue.

At least you don't have the 106-1/4" prop like me for the M462! Going to
require some BIG tires or gear leg extensions for wheel flying if I complete
going that route.

With the airplanes tail lifted into a level flight attitude, or slightly
nose down to cover wheel landings, you should have a minimum or 9" prop tip
clearance to be safe in a tail dragger.

To simulate a flat tire, park a main tire up on some boards that are the
matching thickness of the dimension from the ground to the bottom edge of
the wheel rim. Then lift the tail wheel up in the air in level flight (or
slightly nose down to simulate a wheel landing). This will then simulate a

Hi Ted !

92 " sounds like a lot for a 3 blade on the Moose -
is that the diameter that Hartzell recommends ?? I seem to recall
that the 2 blade paddle was 9 feet - 108". Would have thought that
a 3 blade would be a lot shorter ...

In any case, there wasn't a big problem with clearance with
the 9 ft. paddle - although I was a bit nervous about raising the tail
too far the first few times ! ;-) So you should be fine with a
larger tailwheel.

Hi Wayne !

Maybe you still have the old Super Rebel gear ??? The Moose
gear legs are a fair bit longer than the S-R legs - for good reason ! ;-)
We usually took off a bit tail-low, and I never wheel-landed (it 3-points
very nicely!! ) Going to larger diameter main tires can cause lots
of other problems - those huge 'tundra tires' added lots of loads, and
made landings "interesting" !

No, I do have the newer 3500 legs (and use the 2500 legs as forks on my
backhoe bucket for moving pallets around the yard!). I have no idea of what
I will have for prop clearance and not too concerned at this point ...as I
may not be using MAM's gear legs anyhow. You know me better than that and my
"liking" for spring gear (on ANY airplane)!

I may be wrong, but I was lead to believe that the two blade M14 prop (like
Bill brought to show us last week!) was only about 94 or 96" long. It's the
M462RF's 2 blade metal prop that I have.. that is 106-1/4" long and pretty
sure we discussed it before as being at least 10 inches longer than the 2
blade that MAM originally ran on the Prototype.

As long as Ted jacks the tail up and gets more than 9" he should be good to
go. Subtract from the 9" or more the distance from the ground to wheel rim
and as long as that is positive he should be safe for just about anything.

To simulate a flat tire, park a main tire up on some boards that are the
matching thickness of the dimension from the ground to the bottom edge

of

the wheel rim. Then lift the tail wheel up in the air in level flight

(or

slightly nose down to simulate a wheel landing). This will then simulate

a

flat tire if you measure from the prop tip in it's lowest part of the

arc

and then subtract the full measurement of the boards. MUST have a

positive #

to guarantee tip clearance.

Cheers,
Wayne

18" is for a Moose, 92" Hartzell 3-blade prop, stopped on the ground
with the std MAM tailwheel. I'm just thinking of how the prop

clearance

is reduced during takeoff (pushing the tail up a bit as one gets

going)

and during any sort of a wheel landing. A hangar mate has a 185 with

a

3-blade and his prop clearance was (I think) 24" (or more).

Thanks,

Ted

Ted,

Rebel or a Moose? 18" sounds like a lot even for a Moose. Did you
measure it
in a flight level attitude?

I have a Rebel 0320 with a Scott 3200 tailwheel and It handles very
well. I
never even unwrapped the MAM tailwheel form its plastic.
