  1. Nice L2 kit

    Posted by MICHEL S. on 20th Oct 2020

    Great L2 kit, every components are realy strong, I replace some hardware (aluminium bulkplate), add aeropack minimum diameter retenair, shear pin, and a piston system ejection for the main parachute with kevlar chock cord. Lot of room in the ebay to store the elecronic.
    L2 pass with a Pro54 1016J360-15A-SK , apogee at 1800ft. Rocket is very stable with no speen, Can't wait to fly with a bigger J or K engine
    Many thanks to MAdCow team for the support.

  2. Perfect L2 cert kit

    Posted by Shawn O on 14th Apr 2016

    Fit and quality of parts is excellent. Minor sanding was required in slots to fit fins (preferable than a sloppy loose fit). Instructions are clear and concise. Construction was very simple a straight forward no special skills or techniques were required. L2 cert flight was a very comfortable 2500' on a big "J". This rocket is a rock solid stable flyer on big "K" motors over 7500'. I can't wait to send it up on a big "L". Would recommend this kit to anyone with a little building experience with fiberglass kits wanting to move up to the next level of flying.
