Alright last night i made the paper transition then smoothed it out and added a very thin layer of Elmers Fill n Finish to really smooth it out.
And after about 2 min of rubbing with 0000 final finish steel wool its as smooth as glass.
I also cut out the bottom set of fins and im currently in the process of adding beveled leading edges.

Alright finally got around to priming.
Theres still some light sanding to do on some rough spots near the bottom but other than that this bird is ready for first coat of color.
This first pic is just a full shot.

this pic shows the bottom portion.
But Im really trying to focus on the transition.
Im really impressed with how smooth everything came out the trans. is as smooth as glass. I dare say it might be smoother than plastic.



Any opinions on paint?

ya know that doesn't seem like a bad idea does it? I might have to try that after a few launches. I still need to figure out how much nose weight i need.

As for how much nose weight to add, you should program your design into one of the simulation programs such as RockSim to get an idea of how much nose weight to add.

If you post or send me the details (fin dimensions, nose cone length, body tube/transition length and diameters, etc.) I will create a RockSim file you can view and use with the demo version of that software.
