Hi guys,

I am going to build a Sig 1/4 scale clipped wing cub.
At this stage I am collecting all the stuff that's not included in the kit.
Question from all my learned friends in the cub den is, what muffler do you recomend to fit inverted Magnum 91.
I know people have had trouble starting inverted, but I had an OS. 70 4c upside down in a 1/5 size cub, and it was a real pleasure to start and fly.
It never missed a beat and never a problem to start.
So, what muffler to keep entirely in the cowl.

Cheers all,

Sidekick.
