Once dried, I fitted the two tubes into the coupler. A couple strips of paper were required to get a tight fit that did not distort the coupler. I glued this assembly together using yellow glue. As this dried I stuffed paper towels, dipped in a 50/50 solution of yellow glue and water and then rung out into the cavity between the coupler and the motor tubes to block the ejection charge from blowing out the back.
I let this assembly dry over night and filled and sanded the body tube, nose cone and fins of the rocket. I used three coats of Elmer's Carpenter's wood filler on the fins thinned with water, and the same to fill the grooves on the tube. The nose cone required a few dabs of Squadron green putty to fill grooves.
I glued the modified motor mount with shock cord into the body with yellow glue. I placed the motor tubes flush with the back of the rocket.
The rest of the assembly followed the instructions from the Red Max kit.
I finished this Max yellow and applied the decals as usual. After everything had dried, I used a Sharpie to cross out the "Red" in Red Max and ink in a "2" above the "Max" to make the "Max Squared"
With the engines in place, I compared the balance point with the SpaceCad file I had created for this rocket, and felt the balance point was a bit too far aft, so i added plasticine clay to the nosecone (About a 1" by 1" by 1/2" piece) until the balance was about 1 caliber (body tube diameter) forward of of the CP.

I love the Red Max kit. It is an easy build and looks great. This is an easy mod if you want to double your pleasure and get the "Max" out of this kit. It is a quick way to try something different without going too far out on a limb. The best part is you can fly this off your regular estes launch equipment if you have fresh batteries. Anything more than two won't work, though (believe me, I've tried).
The B6-4 was the best flight. Nice and powerful, but stayed in sight. The C6-5's went almost out of sight, and I only caught sight of it when it ejected. Very spectacular.
I flew this rocket on a windy (10mph +) day, and there was no sign of weather-vaning. It flew very straight every time and only showed the affect of the wind when it deployed and that pirate chute opened up - then it was off to the races!
