This is me Crayola Crayon bank converted t' a high power rocket. T' nearly invisible fins are made o' unbreakable Lexan. Ahoy! Motor is a 29mm Cesaroni H123 Skidmark. Aye aye! Motor mount is 38mm with a reducer down t' 29mm for this motor. Aye aye! This was t' maiden flight usin' a 9 second delay for chute deployment. I now use a shorter 7 second delay. Ahoy! Launched at t' monthly launch o' t' Champlain Region Model Rocket Club - CRMRC. Avast, me proud beauty! June 12, 2010 St. Albans Vermont.
