Dan , my SIM is showing about 7.75 pounds. I'm sure those who have them will be more exact.

Thanks Mark and Chris for the responses. I'm on the road but will respond more fully when I get a chance. In the meantime, yes I am considering options for recovery...I'm using a pre-existing alt sled for now which limits creativity a bit, but I'll see what I can do. Regarding cp, my calculated location is somewhere in the root of the forward fins, but is definitely forward of the root chord mid point. I'm sure my figures disagree with Rocksim but that's just the way I roll.:wink:
Eric, it all depends on whether you use Barrowman or Rocksim method. Either way, the Cp is really far forward- uncomfortably so.
I think it is nothing a foot or two of additional tube would not fix. Either that or a few depleted uranium slugs for the nosecone.
So spill it- how much nose weight did you actually use?
Letters c and d in my ballast post give a pretty good indication. Just finished prepping her for the maiden voyage tomorrow. I am without decent camera this weekend but hope someone can get photos and/or video of the flight whether "nominal" or not!

Okay, so more than 3.3#, and a loaded Magnum is at least 8-9#, no glass. An EZi is probably 6 loaded, so I am somewhere between 3.3 and 7 lbs.
So, steel 4-40 shear pins?

4lbs is significantly less than I anticipated. Does the sim get worse if you use the 76mm mount?
Hey Eric,
Did you attempt to keep the nose tip removable or did you just dump in the ballast? I'm going to have to add an extension onto the eyebolt on mine otherwise the eye will be buried in the ballast.

What's the motor of choice for your maiden?
No damage, happy endings, here she is resting after her flight.
Just add a couple feet of airframe- things will look much better.
Eric- what's the little black FG rocket above the Saab in the picture? The one with the tailcone.
Your thread is making me really want a large saab rocket for my collection
