I modified a 2157 for a 5 motor cluster, and added 2 18mm stuffer tubes to double up on the ejection charge. The other 2 18mm motor tubes are plugged, and I use epoxy plugged C6-0 motors. To get the balance to where Verna recommends, the total weight w/o engines is about 19oz. The nose weight is in 3 different locations in the upper section, so it comes down horizontal as designed.

Flies great on D12 + 4x C6 combo, I've flown it probably a half-dozen times this summer. It's getting pretty beat up from hard landings, the fairings are very fragile. Next time I'll extend the motor tubes so it can be flown with nozzles.
