do i need the baffle?
I've been told, removing the baffle from inside the stock muffler of my 2 stroke will give me higher peak rpm. Is this correct, or will it mess up my back pressure?

The only way you will know is to fly it with the baffle and then without and then you will know!
Can't hurt anything.
If you really want peak rpm "TWEEK THE NEEDLE"[X(]

You may, or may not get a rpm increase by removing the baffle, depends on the engine and exhaust system. Drilling out the exit pipe also may give you some additional rpm, but at the expence of needed back pressure? If your bird runs lean in the turns, chances are you went to far. Fix it cause your hirting the engine in every turn. Want your engine to scoot just a little more? Learn to use a good tackometer and where your engine is most happy. Funny thing is each and every engine will be a little different. Its up to you to find where each one is happy. Usually you can peak it out and back off 5-600 rpm and be in the safe range. I have one that runs best just into the pipe from blubbering, still rich. Once in the air it cleans up, unwinds like crazy and gos like a striped butt bat. Peak it out and back off 6-800 and its a fishing weight at best. A Webra 55 pulling a 10 X 10. ENJOY

What engine? I remove the baffle from all of my engines. They are in there to reduce noise. It may effect your back pressure but I doubt the venturi opening is large enough to effect your engines ability to draw fuel. Generally removing this baffle increases rpm.
The downside is, once you open up the muffler it is difficult to get them to stay together. I am really not a fan of those 2 piece mufflers and the reason why they are is so the baffle can be installed in the 1st place! The best solution is to add one of the MACs one piece black mufflers. These will sometimes show an increas over a stock muffler and somtimes not but they do not have a baffle and they will not fall apart in flight. http://www2.towerhobbies.com/cgi-bin...&I=LXZ649&P=ML
