SOLO flight rules

The R22 is a fine helicopter. However, there are those that fly jet
rangers that would call the R22 a "Death Trap". You suggested that
the Scorpion is not safe. However, you did not specify 'why' you
don't consider it safe.

I don't mean to sound argumentative, but I need cold, hard facts and
not general rumors that the ship is dangerous. What is specifically
bad about the Scorpion? I realize that there are many unorthodox
things being done, but is that really bad?

Take the cable-in-shaft control head for example. The entire rotor
head tilts on a U-Joint rather than cyclicly changining the pitch as
does a traditional helicopter. You might look at that and wonder why
BJ Shramm did it that way.

Here is the answer. At the time, the patent on elastomeric bearings
was still in effect. BJ could not use them. He elected to use
traditional thrust roller bearings. The problem with using these
bearings is that if they are under a load and are used cyclicly
(rocking back and forth with every revolution), the grease rolls out
of the way after a few minutes of operation and the bearings have to
operate without lubrication. This results in a failure.

To avoid this problem, BJ tilted the entire rotor head rather than
changing the pitch cyclicly. In fact, the pitch on the blades only
changes when the collective is moved and not the cyclic. This results
in the grease being retained for a longer period of time. It still
needs frequent regreasing, but at least you don't need a new set of
bearings after each hour of flight.

But getting back to the main point...


Dude, your own statements here are full of "cold hard facts". Read
what you are posting. If you are being truthful, you're trying to
cheaply (forget about it!) find a way to get an obviously terribly
designed aircraft running AND flying yet you cannot fly yourself.
That's like telling a little leaguer that he's gonna start for the
Rams! He'd get killed. DO NOT believe everything you read posted here
from some of the other folks here.
Just go back and reread your own posts and ask yourself why anyone w/
a grain of average IQ would even consider trying to piece together a
chopper from a pile of inferior parts. This isn't "Flight of the
Phoenix". It could wind up very badly.
Save up some $$, finish your instruction in a Robbie or Schweitzer and
then either lease or buy outright.
If you are looking for an inexpensive way to fly helicopters, forget
it. Find another hobby. This one is not for poor folks. Go learn how
to make a higher income.
No disrespect intended, just telling it like it is.
Take care.
