I was able to start on prepping the RSR body Dave sent me (I had the first one for scaling the decals) and took out my xacto #11 with 60w soldering iron. Heated up the tip of the xacto blade and cut out the window details. With the resin 'window tape' gone, the only thing I've noticed is the fragility of the resin in the A pillar and small quarter window pillar. This is in now way any of Dave's fault, just the nature of resin compared to plastic. This is my first resin build and of course, like a knucklehead, I cracked the quarter window pillar and B pillar right at the top next to the roof on the drivers side :shhh: :doh: .
A quick dab of CA glue and kicker fixed it. But, looking at improving the toughness, what to do? I realize the lexan window will add to the strength, but how much?
I recommend a couple things…
- Using CA glue and adding wire, possibly a paper clip and or similar to the inside of the A pillar, B pillar and 1/4 window pillars.
Or (best idea)
- Rough up the resin finish on the inside and spray glue some 300 thread count cloth down, soak with CA glue, let it dry then cut out the windows again. In my experience with RC sailplanes and needing to toughen up a surface without adding too much weight, this method works really well.
Thoughts?
Working with the RSR body, it truly is a peice of art, Dave knocked it out of the park on this one. So far I've carved out a second exhaust hole and filled the little thin bubble holes with Tamiya white putty. Still need to get after the wheel wells and remove excess resin from the mold process, getting ready to start sanding the body soon.
