Maybe he wanted a smaller diameter prop, higher rpm, and to pass sound???

RE: Japanese F3A Championship in Kurobe
The prop on his plane does not look like a 21 or 22" prop. You are safer to spin a smaller diameter prop at higher rpm, than a longer prop with higher tip speed, in regards to passing sound.

RE: Japanese F3A Championship in Kurobe
Kobago, do you know the function of the metal rings on the back? Is it for additional cooling?
I really love this belt solution!

Mr. Akiba said the following thing to me.
These rings are a fillet for cooling.
These fillets are necessary for the hot time of summer.
This is lighter than HACKER Q80-11S F3A.

It's not a belt drive for the prop.
It's none of the above. It's subterfuge only.

It's really a YS sound and smoke generator.

Really nice piece of design and machining.

The belt system clearly reduces rpm. with so he can spin larger props.

Looks like he may have replaced the gearbox with a belt drive. Would be as quiet as an outie.
