According to Rocksim, B6-0/A8-3 works well.
383 ft 5.0 sec to apogee 16.7 ft/sec Vd 3.41 sec optimal delay Maxi-Micron-Booster-18

Unfortunately Estes A8-3s tend to run a little short of 3 seconds.....the NAR cert data says 2.25s. But so do Quest A6-4s - at 3.52s (for the Chinese motors). So the A6-4 sounds right (though it's thrust curve will yield a lower altitude flight).

He should build an Aero-Dart family like I did. Ooops! I still need to build the Semroc Mini Aero-Dart I picked up at NARAM-52.

The little nozzle-shaped booster pod is very clever. I was thinking "maybe I should punch vent holes in it" when I realized that the motor mount design did that already.
I may do something like that on my Lil' Beth X-2 upscale. The tolerances on the wooden slats will have to be pretty tight, but it would look better than punching holes in the booster. * * * Can anyone suggest a width for the black band on the top of the Maxi-Micron body tube? That is: The nose cone is black, but it looks like the top of the body tube is as well.

The model in the photo has a 3.25" black band at the top of the tube.

Perfect, thanks! I am going to need to build a spray booth; my new back yard is tiny, and I don't want to overspray my neighbors' fences and patio furniture.

I have one of those with one coat of balsa fillercoat on it..... Not sure I'll be trying to do an Aero Dart family beyond that, but I did also just finish a mount for the 29mm Estes BP Es and Fs so I can fly the one in the picture on those motors at NSL, hopefully..... Its first two flights on an Estes D12 and E12 were sure nice. Oh - and back on topic - got the second order from Carl and Sheryl and company with the Maxi Micron and Booster-18 in it. With a little luck I'll bring those to NSL as well. I now have Centurion F number 00008 and 00026. I'll build the second one I think.

New SEMROC Kits
My Maxi Micron was delivered yesterday, looks to be similar in size to the SLS Explorer.
When I build the MM, I will go to my box of old parts and use some Flight Systems centering rings, modify them to fit a 24mm tube. and fly this kit on C11's and D12'S. I think I will leave the 18mm tube out of the Booster as well. I don't know what 24mm motors will do to the CP -CG, I will compensate with washers as needed. The Maxi Micron / Booster 18 flying on a C11-0/ C11-7 -D12-0 / D12-7will be exciting. SEMROC has some of the most interesting kits on the market today.
