Estes 1376 NASA Pegasus

[Charles_McG]

I'm scratch building a Pegasus downscale, does anyone know where the Cg is supposed to be?

Umm... Ahead of the CP?

:grin:

Sorry, couldn't resist...

Pegasus was one of my old favorites and I had forgotten about it until your post!

While I can't answer that, I can curse the memory of yet another .ork file lost in the HD crash.

30 day Rocksim trial for the pods?

 

[Charles_McG]

I used the 30 day trial simming a Titan IIIe.

OR will do tube fins too, should be able to handle a Pegasus I would think. K'Tesh?

Yes, and no...

I simmed up the Pegasus up, but due to the lean of the fins (not perpendicular to the body tube), I was unable to get them to work properly (touch, but not go through the tube fins). I was hoping that a future release of OR would fix that, but lost the file when the HD crashed.

I had forgotten about the new-ish tube fin capability.

And Jim is right, you can get close, but can't make OR 'lean' a fin over so it isn't perpendicular to the body tube. Still, close is good enough for me, in this case.

Hmmm... it looks like I've only got about 1 caliper stability when loaded up. Guess I'll have to drill into the nosecone to get some weight further forward.

Very Nice!

Another great kit Estes should think about re-releasing!

Looks great. Did an upscale about 2 years ago as a Christmas gift for Dad. Always a favorite around here.

I've got a Mega Der Red Max and some Leviathan tubes waiting for upscale time.

By request, here's the ORK file that goes with the above pics.

NOTE: This file is for a BT20/BT5 based downscale- not the original, which I believe was BT55/BT50 based. (Tube reference double check... yep) It's less than ideal in several ways, and would make Jim/K'Tesh weep with sorrow. Your milage may vary.

would be a great rocket to bring back! Makes a great 3 motor cluster flyer.
