Then we let the epoxy cure. Do *not* glue the aft ring to the MMT yet! That comes much later. +To be continued... + ## Flights +All three prototypes were first flown at [NCR](http://ncrocketry.org) Mile +High Mayhem 2010, on the new Cesaroni 159G54 c-slot long burning red flame +"full G" motors. + +Bdale's broke a mile, but we somehow failed to pull the +[TeleMetrum](http://altusmetrum.org/TeleMetrum) data before re-using the board +in another airframe, so we can't prove that. However, the fin can separated +and has not been recovered. So much for painting a tiny fin can black! + +We learned the hard way with Robert's airframe that silver Krylon paint is +metallic enough to hamper GPS reception, but the UHF downlink was strong and +we found the rocket easily using RDF techniques. Robert's also separated at +apogee, but thanks to the flourescent pink paint +job, it was found between the rest of the airframe and the flight line. + +Keith's flew nominally. + +Robert flew his for the second time at Tripoli Colorado's Spring Fling 2010, +again on a 159G54. It dragged a bit on the rail, ended up in a non-vertical +trajectory, and again failed to break a mile AGL. Oh well. + +## Conclusions + +This is a fun little rocket, and is indeed capable of breaking a mile AGL +from Colorado launch sites using the 159G54 reload from Cesaroni. It was +Robert's first introduction to flying drogueless dual-deploy. Building +without the Giant Leap rail guides and tower launching would be a good +plan for future renditions to get more altitude, though as Robert points out, +that would make it harder to sport fly at random launches. The slide-in +ebay design worked out very well, and keeps the number of airframe junctions +down.
