Here is the manifold I made from fibreglass to fit the stock 87 throttle body.

I have not flown with it yet but on ground runs it seemed to work great.

This bolts to the stock lower maninfold that I hacked and ground on to

reduce weight.

Won't do that again, too much work.

Round trip runner length is about 25 inches.

Very nice.  Thanks for the pic.  

 

Cheers,

Rusty (prop problem solved- Thanks Tracy!)
