LV2 Flight on a Pro54 J380-SS. flew to 1,136 feet. a 4 foot drough was deployed at 1,100 feet, which pulled out my 5 foot main chute as well. All and all every thing worked. :) special thanks to the Dracut Fire Dept. for suppling a extra peice of fire hose, that was use for its kevlar covering to help protect the shock cord. Also a BIG thanks to Robert and Gloria Dehate from AMWPRO.com, and Scott from the MMSC rocket club in berwick maine, and of course to my folks who let me do all of the testing and building in there cellar and back yard! i couldn't not have done it with out ya!
