“I plan on using an RMS motor in this rocket as well as BP motors and the design has a baffle in it. I was not sure if you can use a baffle with the RMS due to the red cap that blows off the ejection charge. I thought it may damage the baffle...”

You're right about the cap causing problems but that's the least of it. I strongly reccommend a beefy motor mount (made of 18 motor tube - not BT-20) and a VERY substantial stuffer tube (maybe foil lined) for this model. The heat from AP motors is intense and can cook your paint job in one flight.

I say this from experience. I built a BT-60 sized Centurion to use these motors. The heat damage sustained from the first flight necessitated cutting the whole bottom of the model off and starting over.

Also, make sure to attach the fins and tank tubes very securely as the sudden thrust of these motors can jerk parts loose or right off.

Good luck with this model. It's always been one of my favorites.
