Since I have been asked, here are some photos from a launch last week of prototype # 3 which is very promising. I had 2 1/2 flights
The first was very nice (the one in the photos) , F12-5 cut down delay to F12-3, with a bit of a CG problem due to an oversight of using the parts of the aerotech case (24mm) and the nozzle, liner, cap and thinking that was ok. It appears that I needed an actual used motor as their is fair amount of residue after burnout. This caused a bit of porpoising at first, but was brought under control with a bit of down elevator and flew with a smooth glide which I promptly landed into my friend's leg just before touchdown. The wing sheared cleanly and was repaired shortly after. This is why I now have TWO prototypes of my model.
The second flight (first of the second prototype) first had a bit of trouble igniting, then promptly blew out the nozzle and end of the case (Aerotech F12). On to case # 2 (sigh). Since the first seemed a bit early on ejection, I went for the "full" 5 second delay - did I mention this was an Aerotech motor? - I was treated to a "bonus" delay that went after about 8 seconds (the model was already sticking in the ground by this time). It is very repairable and both models have taught me likely failure points and where to improve on the future kit.
I will have the two models at NSL and will fly (weather permitting). Suggestions are always welcome.
BTW: These photos are taken by Jim DePape who also got some stunning shots of my Gamma and Delta Stars during NSL 2012 this past weekend!
