Tailwheel angle on a Super Rebel

[Mike Kimball]

My buddy Rob Merdes has his Super Rebel on it's gear and we are both shaking
our heads at the Murphy tailwheel. The pivot axis is angled significantly
rearward. It makes it very difficult to push the plane around on the
ground. The tailwheel keeps wanting to end up backwards. Surely something
is wrong???

On a lighter note: The prototype cabin top mounted flap assembly is nearly
complete. It looks like it is going to work great! Flap deflection and
aileron droop have been separated to give the pilot the option. Aileron
droop will be via a MAC servo. I keep promising pictures for the archives
and I still haven't gotten to it. I'll get it done eventually. There are a
couple of questions that maybe the list can help answer:

1. What is the maximum aileron deflection with the standard installation and
full flaps?
2. Are the ailerons reflexed up when the flaps are set in the reflex
position?
3. What is the full flap deflection with the standard installation?
4. How much does the mixer block move from reflex to full flaps?

P.S. Has there been any final conclusions on what made the gear fail on
Al's Super Rebel? Rob and I are contemplating steel webs on both sides of
the fitting that failed, bolted through the casting where the tooling hole
already exists and in one other spot closer to the bolt. The gear leg would
then rest on the casting and each web at the top. Any opinions on how far
away from the bolt the other holes should be? The other option would be to
make the parts out of chrome-moly instead of aluminum. We'd have to cut the
old ones out and make the new ones skinny enough to put back in then slide
in spacers where it bolts to the box structure.
