There were two parts to Project Optima. Part 1 was from December 1987 and Part 2 was from February 1988. Scans are attached.

I think the parts will be fine. Here is a paper on the tensile strength of nylon sutures after exposure to 3% hydrogen peroxide: http://www.utsouthwestern.edu/utsw/cda/dept28151/files/338868.html Per table 3, there was a slight reduction in the tensile strength, but it was not statistically signific...

In my opinion, I think you shouldd leave the metric 0.8 module (just about the same as US 32p) gear set on there. The various US 48p gear sets that were offered made pinion gear selection easier, but they didn't strengthen the drive train; the original gears are pretty strong. I've run 12 and 10 tur...

How about a Kyosho Cactus? It doesn't have the pinion + spur arrangement you described, but it does have the other features and a very odd gearbox . The grooved tires front and rear were stock.

That Mustang is a fantastic set. It's on my list too; hopefully by the end of the year.

Lego sets are like potato chips...and vintage RC...you just can't have a few!

Nice!

As of Wednesday, the Stranger Things set is on its way to my house:

This may help; no can colors, though:

I don't know exactly what the pros use, but here's my materials experience in vacuum forming... Thermo/vacuum forming requires a rigid, tough material with a low coefficient of thermal expansion, as well as the ability to withstand cyclical 400F+ temperatures. As polycarbonate cools and shrinks, it ...

Made some more progress today. Got the steering servo in, battery mounts installed and an additional chassis stiffener behind the spur gear. At this pace, I may actually get to test run it (sans body) this weekend!

It looks great!! You hid the Swiss cheese portions very well.

Thank you all for the compliments; I really appreciate it!

Yes, I will have videos of it running. Possibly this evening...

First video running in the backyard with the body, brushed Slot Machine stock motor and 2S Lipo battery. KVDNHFPf8HI And the first casualty from that flip: Casualty.jpg Time to redesign and re-print! The front and rear shock towers are bent a bit too; I will probably leave the aluminum in the rear, ...

I really like this build/restoration. Fantastic!! And, as someone else mentioned, such an informative write-up. My knowledge of Yokomos starts and ends with the 834B, so it's great to learn new things and see the evolution from the YZ-10. Thanks for all the detail!!

I'm excited about this car...and parts...and spare oem body. I think it will be a shelf queen, which is not something I usually do, but then I won't feel bad about occasionally running my other one.
