Having been inspired by a number of Goony threads on this forum, I add a new creation to the list. This is my Goony Phoenix, probably to be permanantly christened the Goonix. I'm still working on priming it and then will finish the paint and look into some decals. It has a 24mm mount.

I have a few others in the queue: a goony upscale of the Quark (named Duark?) and a goony upscale of the 220 Swift (.44 Mag-Goon). I'm also going to start work on a goony Estes Alien Invader.

Marico,

Have you worked this up on RockSim yet?

I haven't. I've never used RockSim before.

I'm presuming you used a BT-60 and a Bertha nose cone, like most of the other Goonies. Send me a free-hand sketch of the fins, with dimensions, and the actual length of that body tube. You already said you were using a 24mm mount, so putting together a RockSim file shouldn't be difficult.

Just attach them to a reply on this thread...

Thanks for the RockSim help. The BT is 7.5" and the fin dimesions are attached.

Thanks for the drawing, and for working up your prototype. Attached is the RockSim file showing the results. Hope you don't mind my adding it to the BARCLONE website...

Length: 10.00"
Diameter: 1.637"
Fin Span: 5.64"
Weight: 2.3 oz

This model requires 3/4 oz of weight in the tip of the nose to fly correctly on the 24mm motors listed. It is totally unstable without this ballast.

C11-5.......600'......Dv 4 FPS.......36" x 1/8" launch rod
D12-5......1160'......Dv 25 FPS......36" x 1/8" launch rod

The model will fly nicely, as long as you add the ballast.

Enjoy!

Are you kidding? I'm thrilled to make the cut.

I'll post some pictures when I get it in the air.

And thanks again.
