Optima " Mid "

Recommended Posts

I have been planning this for a long time. Now, the basic idea is done.

I got a 3d printer and a cutting machine to make parts or plates.

However, the biggest problem is I don't have a lathe to make shafts.

Nice project - belt cover will be an interesting design

Making a belt cover won't be a easy task. On-road only. :P

A small step.

I've got three parts for this project. Rear wing, belt tensioner, and 250XL belt.

neerly done. My front damper stay already bent, so it may take a while to fix this problem.

This thing is incredible? Have you made any more progress?

Not much.

test run didn't go very well. I guess I need a new front damper stay.

I can check my spares but if I have anything its probably bent. Pargu makes them new and sells a tall version. You might also get some more die-hard vintage kyosho guys looking at this if you post it on rc10talk or oople. What wheels and tires are you running?

Thanks for your advice. I had tried and couldn't get an acount for RC10talk.

As for the damper stay, I think I can handle this problem.

In fact, I'm working on it and later on I'll have 2nd test run.

Whaou really like your work done on this Optima, would you mind if I posted this picture on my website, and of course, give credit and link to this thread.

I got a second thought. By moving a plastic part, the battery can be moved forward or backward.

Body mounted, not a perfect one though.

Put this on and I'm suprised that the body of Optima Pro fits almost perfectly.

There will be a driver, not this one though.
