Maiden Launch of Cosmodrome Black Brandt II pics
- Thread starter firemanup
- Start date
Maiden flight liftoff pic on a G64, wasn't quite ready to put her up on an H... 
now the aftermath, everything came back under chute ok, BUT
Apparently those sharp edged plywood fins are stronger than the balsa nosecone.. cone came back and hit a fin.. looks like someone took a hatchet to it now..
Will replace it with a plastic cone and hopefully not have this problem in the future..

The balsa nose cones is what turns me off about the Cosmodrome kits. They seem to look like really nice kits but I don't want a nose cone to look like a hungry dog took a bite out of it after one flight.
Resin would work but I'm sure it would be way too heavy and expensive so I'm sure a good quality plastic would be the way to go.
I kinda like the Vostok myself although the BB2 looks awesome too.

You should check out Red Arrow Hobby's 2.56" (PN - RAHNC256C) conical nosecone. It's made of fiberglass and filled with 2 part foam. Only $12.95.
VERY nice bird BTW! Perhaps someday I'll get around to building my scratch BB2.

Nice job Jason -- too bad about the nosecone. The balsa nosecones are one of the things I like about the Cosmodrome kits. I'm still trying to finish up the Nike Smoke and although I fear I could have similar problems I enjoyed the sanding/filling/sanding/sealing/painting.

NICE rocket!!! I've already flown mine on G35's...THREE times!
Oops, I meant the smaller one
Really, they're both quite sweet... too bad about the NC. What's a flown rocket wthout a war wound or two?

Who needs dogs ; I'll loan you my wood chewing macaw. We'll get that thing properly detailed before it flys.
Cosmodrone really does a nice job on the nose cones. I've got the Nike Smoke kit waiting to be done. One of these days.....

I saw they have a nose & tail cone set for about 19 bucks. Do you think it'd be worth it to replace the tail cone, too? I can't imagine it would see that much damage.
Did you sand the faceted airfoils on the fins, or just round them? I'd like to build this kit just for the challenge of doing all that by hand and getting it right. It's probably a real screamer on an H180.
Chilly,
I did the leading edge, and trailing edge to scale, marked out using their measurements and did them both and they came out pretty nice.
There's a third angle between the leading edge back about halfway down the fin, that angle i didn't attempt, i had the other two done nicely, and that one looked pretty difficult for me and i didn't want to mess up the other two... so... i left it with just the two.. still looks pretty nice..
I'll be getting ahold of RAH here this week sometime if i can find the money..heh... and order a new nose cone.. the tail cone is pretty well protected inbetween those fins i think it's going to be fine..
