RE: I'm making the Stinger again
Thanks Scott. The fun of the Q-40 planes is that they get more speed than the 424 planes and they look cool. They really capture the attention of the sport flyers. With the TT Pro 40 they are still not into the "scary fast" range though.
Here is a photo of my epoxy pump station. One resin. Four different hardeners with different purposes. You can batch the same hardener during your work, but you can't mix hardeners. One pump of resin to one pump of hardener and it cures every time.
A lot of people try to clean up epoxy with alcohol. Acetone works much better. Don't get it on foam though. It can even clean epoxy off of most plastic coverings without hurting them. Use gloves whenever possible. Acetone will clean your brushes right up. At $1 for a bristle brush it starts to add up. $0.10 of acetone will save that brush.
