Has anyone ever used these mufflers on a TT Pro 46 or an OS 46 FX? Just wondering if they give better, equal or less performance than stock?

TIA

Isn't that same as the Tower muffler?
There is no lack of info about the Tower muffler if you search.

They bolt on perfectly to a MDS 40/48, 40 & 46FX. TT PRO 46, etc.

You will need to readjust the needle valve.

These mufflers are bad about coming apart up in the air after you use them for a while. Early on, double nut the through rod. Eventually the through rod will pull out of the front piece. Then you will have to put a threaded rod all the way through it with double nuts front and rear.

Works better with smaller props that will let the engine turn up some rpm. (10-6, 11-6)

So there is no difference between Tower Hobbies muffler and the Hobbico muffler, the only difference is the Tower Hobbies muffler is $2.00 dollars more. If this is the case I will try the Hobbico muffler instead of the Tower Hobbies muffler unless someone can tell me another difference.

Thanks
