So, being my usual dumb self, I haven't built a single glider for NARAM yet. In a field of very challenging events, D-RG Free-Flight, might take the cake as far as complexity. So, naturally, I've whipped up a design in the past week and will be laser cutting it next week. (Smoke it if you've got it, right?)
This design is a massive scissor-flop glider. I decided to go that route because it puts lower stress on the wing during boost, thereby allowing me to have a larger wing made lighter. The specifications are as follows:
Wingspan: 42"
Wing Area: 336 sq. in.
Overall Length: ~44"
Engine Selection: Estes D12-3, E9-4; Aerotech D7, E7, and E6 w/ altimeter or R/C deploy, maybe AT E11-3 and F12-3.
Estimated Glide Weight: <150g (I hope)
I've attached two screencaps of the solid model, the first in boost configuration with a 4' long 1010 rail for size comparison. (Coincidentally, that is what I am using for a launch guide.) The second one shows the glider in glide mode.
