Lickably good finish.

Thanks Colin! Interesting choice of verbage, but taken as a compliment of course.

I just received the vinyl decal I ordered for my Mongoose. I got it HERE.

Here's some pictures of my Mongoose now...

Oh so shiny.

So when will this fly?

 

[Johnnie]

Won't the heat from the friction of air racing across the airframe melt it off when you put a big motor in her...? Heh heh

Looks great Kevin!

There is no field (that I'm aware of) with a standing 30K+ waiver east of the Mississippi, so it looks like we'll be making a road trip to Kansas in '09 to visit the Kloudbusters.

Thanks, Johnnie.
Actually, I'm counting on it! That's why I ordered an extra one, just in case...

WOW! looking great!

tell me how it does, and tell me if the decals hold up to the speed, I'm really curious.

Kevin, real nice job. Are using an aeropack on this or forward retention?

and can you use an aeropack and if so which one?

thanks, bob

Thanks, Bob. I'm using forward retention only as described earlier in the thread and it will be more than enough for this rocket. In case you want to search for one that will work, the OD of the tube is 3.14". I'm not aware of an off-the-shelf retainer from Aeropack or anyone else for that matter that will work with a MD 3.00" rocket. I know it's been done on some of the smaller Mongeese. But even if there is one that would work for the 3.00" tube, it would have to be 'faired-in' to allow a smooth transition for the airflow over it. There's already going to be an ample supply of heat during boost, and that would increase drag in that region and also create much more heat. This factored into my decision to use forward retention only.

(Sorry, I forgot to add a picture) Here's the business end with the AMW case inserted. I'm going to have some turbulence due to the thrust ring being larger than the OD of the tube. At this point I don't plan on machining the ring , but in time I might change my mind and do just that.
