Very cool designs Andrew!:cool:...However, looking at those DV numbers is kinda scary!:eek: That is WAAAAAY up in the 'shred the parachute/massive zipper' speed region...I downloaded the -D2 design and played a little with some different delays-mainly SHORTER delays and got the DV's down quite a bit...

Here is what I got:

C11-3 211 ft alt with a DV of 7 f/s
D12-5 613 ft alt with a DV of 8 f/s - Well, didn't have to change THIS one..:chuckle:
E9-6 1111 ft alt with a DV of 22 f/s

As you can see, the shorter delays are a bit better..But, maybe the long delays is all you can get 'down under'?

Thanks, pantherjon

and there more designs to come, lots more :)

RS9 is the best programs to come out form Apogee.

I'm having a MAD design frenzies at the moment :chuckle: :cool::cool:

Andrew, your TAU JA-7 is sweet looking!

The DV for the B and C are way too high even for a streamer. At that velocity the air frame will hit the nose cone putting dents in you balsa. :( try tweaking the design to bring the DV's down.

The DV for the A is good for a school yard sounder. ;)

Andrew,

I think you'll like this revision. It's minor, yet major in terms of performance. This design is just screaming for 13mm power! What I did was change the engine mount a bit to take a standard 13mm casing, then tried some runs with both the A3-4T and the A10-3T. The A10 is the better engine, but both give nearly the same altitude and Dv numbers. The A3 needs the whole launch rod, however...


A10-3T......317'......Dv 15 FPS
A3-4T.......324'......Dv 13 FPS


Don't be afraid to try 13mm power in designs like this one. The final numbers will surprise you.

Andrew,

You've probably noticed the changes we've made here on the BARCLONE forums. We tried to update the way we handle design posts and discussions, so that everyone can locate our latest plans easier.

As you develop your new designs, go ahead and start a new thread for each one in the "Designer's Studio" sub-forum area. I haven't locked this thread down yet, but it will at the end of the year if not sooner. We also have a weblog site, where I post a few RockSim 3D pictures of designs. And I am "committing myself, before this decade is out, to complete the BARCLONE website" that I've been promising for the last few years...

Andrew,

I'm going to post both versions to the Master List. This is a great-looking design!

Thanks!

I just got a box of parts from Semroc today so I will start building a 13mm version of the TAU JA-7 :D

I've been looking for a unique 13mm to build from scratch and this one caught my eye.

Look for a build thread in a few days here on YORF. ;)

What software was used to build these? Where can I get it.
