I have done one upscale of these really nice kits from Semroc. Finally got the stuff to begin another. Don't let the supplies fool you at first glance. They all need to be cut down, trimmed and turned! I got double the amount of bass wood needed in case I mess up turning the cones.
See the Hydra in two different versions from Semroc at:
See the attached photo of my current Hydra on an H170 last summer in Champaign, IL with my local club (http://www.ciarocketry.org/), a great bunch of guys! Plan flying the new one on J800 up to K700 and this one will be dual deploy.
Planning on getting this done in time for flying at Thunderstruck 2012 (http://www.indianarocketry.com/thunderstruck/). I'll try to include different parts of the build I think might be most interesting since this is not your ordinary 3FNC rocktet! Cool. Hope you all like it!
