Hey all,

i am pondering if i should buy a pitts style muffler for my Goldberg Cub ? probly be riged with an os 61... not sure yet

Heres mine with a ST 40 and bisson pitts muffler

Its alot nicer dont you'se think ?... how much did u get urs for

If your going to use a 2 c , I would go with the in cowl muffler.

I would recommend a .70 4c on this plane . I did use a Magnum .52 , 4c for a while . Flew O.K , but a .70 size 4c would be a great fit.
By the time you buy a muffler , you`ll have the price of a Magnum .70 .

well im looking probably at a .61 for the first engine unless i find a good deal on a 70-.90 4s... i would rather that but preatty pricy for 1st engine lol... the pitts looks much better i find lol...
