Most of the problems with the one I have are due to age. A lot of the
aluminum parts have surface oxidation that must be hand removed and
polished. I am planning on having all the aluminum parts hard
anodized so that they don't do that again.

The tail rotor slider mechanism was rusted and I had to work it pretty
hard to get it going again. I am planning on having the TR shaft hard
chrome plated so that it will wear better.

The steel frame is actually in remarkable shape. I'm not sure what
they used to paint it, but I hope to get something that good to
repaint it.

The only components that I am really worried about are the blades.
They only have about 25 hours on them, but also have age cracks in the
composite.

I haven't contacted BJ about the Scorpion One. I don't think he would
have time to talk to me since he is very busy with his helicycle
project. I have the blueprints for the Scorpion 2 and was considering
getting those for the One, but the One is almost identical to the 2 so
I'm not sure if I should bother.

The bent cable is for the collective. Its a nutty way of doing
things, but it does work. Its just not as good as a regular system.
The only real problem with the bent cable rotor head is that it does
not use elastomeric bearings. It uses unsealed thrust bearings
instead. However, because of the way the cable head works, they only
move when you actually move the collective. I'll probably have to
spend a bit of time every few hours of operation greasing them, but a
friend showed me a trick where I can grease them easily with a
hypodermic needle. Hopefully that will make operating it more
manageable.

I'm still not sure what to do about the license.

I had two Scorpion ones and sold them to a guy who had an A&P try to get
them going. They still have not been in the air. He had a lot of trouble
with slipping tail rotor belts. There are some problems with the old rotor
head. B.J Schramm, the designer should be contacted about those problems.
I believe I heard him tell one person not to fly the version with the looped
cable in the head. I used to fly a Benson gyro with a McCullough engine.
It was a quiet sewing machine compared to the sound of the Evinrude engine
in the Scorpion. Be very careful.

My scorpion is a single seater and is not completely restored yet. I
checked with Rotorway, but it does not seem that there is any way to
get instruction in a scorpion one. I wonder if a scorpion 2 is close
enough. The scopion 2 and scorpion one are basically the same
helicopter with the 2 being bigger and wider.

It is starting to look like I'm going to have to get my certificate by
soloing in the R22 and then just switch to the scorpion afterwards.
It seems like thats a waste of money though since I will have to
relearn everything in the scorpion.

I have all the parts to the scorpion one, but I am not sure what to do
with the rotor blades. It looks like there are fine cracks in the
composite. I wonder if simply recoating them with new resin will be
good enough or if I have to rewrap them. They only have about 25
hours on them.

I will also say that the scorpion 1 was definitely not designed for
people with normal length legs. Its a real pain getting in and out of
it.
