BFT flew today on an F50-4, I'd say about 800'-900'. Ejection timing is near-perfect. Sadly, all I have is a post-flight photo, but I like it nonetheless :=) Ari.
How big of a chute is that, it looks quite large? Is that because of the terrain this launch was at? Looks like an airfield ( lots of asphalt)? Did you go with a lower lug or use your thru the tube fin idea?
Now I've seen an M2200 (or M3000?) shred the fins off a 6" Kraken. This is significantly more thrust per much thinner fin. 6" BT is about as thick as 38mm, but with 4 times the circumference. Kraken has 4 fins, meaning each has a single connection point to fuselage--unlike the 6-pack arrangement where each fin supports the two next to it. Again, no predictions, just trying to convince myself I'm sane.Ari.
Iter I have a question about tap plastics isp weld on and hdpe . But your in box is full
That makes sense and goes along with what I thought...didn't think of the blind nut on the other side, tho.I use an 8-32x2.5" machine screw that goes all the way through the body tube and screws into a blind t-nut on the other side from the rail button (t-nut is on the outside of the rocket). To this screw I tie a loop of kevlar shock cord which in turn quick links to the parachute and NC. The rail button is far enough from top of rocket to make it difficult to use a normal nut inside the BT, and I want to keep it low enough to let the entire laundry to sit above it lest the laundry hangs up on the bolt.
Does this description make any sense? I'll try to photograph this arrangement when I get home.
Ari.
How high? How fast?
Also, wow. 6 motor classes...
So it most likely exceeded Mach?
