Looking to do everything in Micro Rocketry was are doing with standard size model rockets my first attempts at staging were with two all time favorites the Warp-II and Hercules 2 stage. Warp II material redacted Micro Hercules on the other hand had a Straight T2+ body/payload configuration using a slightly larger then T2+ clear Polyethylene payload tube. I did use Basswood on the fins for both models and this has proven over time to be a good choice helping to keep the Hurcules fins from warping as it's full size brothers have over time. Both models were tape together motor configs which proved over test flights to NOT be the most reliable method. through experiments with several configruations with and without ejection it was determined leaving the motors untaped increased the upper stage ignition reliablilty considerably. When these two models are replaced they will be slightly Upscaled to either T2++ or T3 main body tubing to allow Gap Stage Venting back thru the centering rings and perhaps a slight side vent holds at the stage joint. Both are really fun flying models single or two staged. Post copied with permission .
