Estes Quinstar #7241 Build, Part 3, Balsa Prep

I usually sand off some of the burnt laser cut edges.
Don't take off too much, the fit of the parts might end up too loose.

When the center pieces are removed, there are many hold down "ticks" left along the sides.






It takes a while (there are a LOT of cut-outs) but they can be smoothed off.
Some 400 grit was wrapped around a dowel and the hold down ticks removed.






Here's an after shot showing some smoothed cut-outs.
