Operation transformation......32-year old Schluter restoration

It's been years since I got this Schluter MiniBoy in a trade.
I have no other projects at the moment, so I may as well get this show on the road.
I want to restore this to working order using period-correct electronics. I have most everything I need. Attached are the pics of what I have.

Step #1:
Re-Kit it.
I'm disassembling everything all the way down to the screw.
This is going to take a while. I started with the blades and tail.

I re-kitted the head, and took apart the motor and rebuilt it.
The motor cleaned up nicely and looks great.
BTW, I soak all the metal pieces in gas, dry and then dip in carb-cleaner.
That really does the trick in removing 30+ years of gunk.

Looks like an interesting project - it has been a long time since I have seen a heli with the heliball muffler (I still have one in my workshop). Noisy things they were.

This is a very different project indeed.
The last four helicopters I have built were pretty much turn-key nowadays, the latest being a hobby-king 450 of some sort.
I've easily spent 5x as many hours taking this one apart as I did putting a new one together!
When I'm done, I'll box everything up and sit on it for a few months before I assemble it and set it up.

All cleaned-up and rekitted!
I finished about 3 weeks ago, and pulled it out of storage for the pictures today.
Every part is accounted for and in great shape.
The clean up involved a combination of:
Solvent soak (gasoline) for moving metal parts like bearings and the pre-assembled head.
Carb-dip w/brush for all metal components.
Rust disolving dip for those few parts that had some surface rust.
Hand polish for most aluminum parts.
Water soak (with a little baking soda), followed by water-only soak.
Compressed-air spray-dry for all parts, and air-dry for a few days after that.
Packed away.

All components are sorted per the reverse-order "assembly instructions" by major-component.
All moving parts have been lightly coated with machine oil before they got stored.

Here are some various pictures of the "used" kit.
My next project is to actually build the heli back to 1982 original condition w/1982 electronics.
I have no timeline as to when I'll start that.
Based on the way things cleaned up, I expect it has potential of being one of the best "original" schluter's out there when it gets put back together!

And now, the electronics!
The gyro needed to be cleaned up. After 30 years of sitting the bushings needed a light dab of clock-oil.
Interesting device.
It has two inputs: An enable input, and a rudder.
One output: Rudder servo.
One optional power (for independent power for gyro only)
Five user adjustments:
Gyro On/Off. This spins the motor. This spins the motor up.
Two gyro sensitivity adjustments
Tail servo center.
Tail servo reverse.

I flew with one of those not even that long ago...
They were actually pretty good,and very suitable for the old fashioned wire-driven tailrotors with their large torsional flex....

I was tempted to do an electric conversion, but decided this is going to be a display model (100% stock RTF). I expect it will be a winter project.
Between the as-new gold anodized Futaba (first generation FM) radio, and super-clean finish/fit, this is going to be impressive.

PS: The engine fan clear plastic housing is pretty rough. Does anyone have a like-new condition one?
