Well I have some construction photos yet to scan in, but here's
sneak peek of my project for the last month or so. This pic is
from my $20 pencam, so the quality isn't the greatest...
I call it BARnone since it's my first scratch built since returning
to the hobby (computer folks like to start counting at zero )
The rocket is 51 inches, with a 24mm MMT. The BT is a
plastic drafting tube just a hair over 2" OD. Dry weight is
12-1/2 oz.
The fins are 1/8" balsa epoxied TTW. The leading, trailing and
tip edges are 5/8" caps for added strength.
The nosecone is 7 inches long and homemade on a drill.
It didn't turn out as good as I had hoped, but not bad for a
first attempt.
This uses a piston ejection of my own design (had to do
something to make this more than just 4FNC). The
BT & fin can separate 8" from the back. The piston
actually pushes the coupler out of the fin can.
I have a 24" Estes plastic chute inside now, but hope
to locate a suitable 30" nylon one soon.
I purposely designed it to be overstable (those fins
are 4" root x 3-1/2" span) so I can experiment with various
engines, chutes and even alternate bodies.
This might just get a flight on Saturday if the vendor
supporting the launch has any AT E15's or E30's.
Wish me luck!
