No, mine is predominantly yellow and blue, but the cg marks are3 dots on each side of the fuse. They are located on the top of the fuse under the hatch. I dont know of any cg issues with the red one i assume it is an older model...but icould be wrong..

Have many people tried running an exhaust canister through the fuse under the fuel tank or is the norm just a basic pitts style of muffler straight out the bottom??
