  1. Love it!

    Posted by Rick on 27th May 2017

    All the parts fit well and it went together with no problems. I used wood glue for the entire build.
    I flew it twice today, once on a G54W and once on a G79W, both 29mm. Both times it was straight as an arrow and quite fast for its size. I used a chute release set for 500' and got nice soft landings with minimal drift.

    Overall, a great addition to my fleet.

  2. Gotta love short and fat!

    Just finished my 4" Cowabunga, its easy to assemble and if done smartly can easily be kept under FAR 101 restrictions and flown on Mid Power motors. I built this rocket with Titebond II wood glue for most joinery, and Titebond No Run No Drip/Molding and Trim Glue for the fillets. The rocket without motor or recovery is weighing in at 1.8lbs and should stay under 3.3 Ibs
    Picture of rocket can be seen here : http://tricitiesrocketeers.freeforums.net/thread/351/madcow-cowabunga-build-thread
