My Optima with mid motor conversion

[lin6499]

Hello, I'm a new guy here and this is my first thread.

Why I did this was just for fun, didn't think I could build a better car than Kyosho Optima Mid.
You guys may be aware that there's no a gear cover.
Right, because it is kind of difficult to me to make one.

Those custom-made, white plastic parts were made by 3D printer.

As an Asian, excuse my poor English.

Box-art

The belt of LWB Optima Mid would be too long.

LWB: 254XL
Mine: 248XL
SWB: 240XL

Neat looking conversion. White parts are 3D printed or machined? I wonder if the axle on which the yellow pulley sits, won't give a little if the drive belt is stressed during hard accelleration or braking.

First, those white parts are 3D printed.

Second, I think two pulley-bearings are more vulnerable than the axle. It seems the bearings are fine.
However, the current motor is 540 silver can, I'm not sure what will happen when upgrading to a powerful motor.

Here's the one I (my Dad) did in the 80's. The Optima Mod

This is the only pic I have.

No under body shots I'm affraid but you can see the orange belt.

It didn't go very well, but maybe that was the Sanyo 1200sc batteries.

Pity. I wish we could see more detail about it.
