RE: PRIMUS Build
Raineday,
My HVLP gun is different. On line its about $36 and is purple with the paint cup on top. I haven't tried precision painting in a long time and it shows. I made every mistake in the book and a couple that weren't even worth mentioning. I will learn the SPA most basic pattern so I can fly in the Atlanta contest later this year.
KlassKote is expensive. It costs $160 for the paint to finish this plane. It works ok but when they tell you not to spray on top of a coat for 48 hours they really mean it. I rushed the painting by putting a color on every 24 hours and it does not seem to have bonded well to the prior coat. My fault, I was in a hurry. Also I need to get some good lamps for the garage so that as I am spraying I can see what I am putting on, this is especially true with the clear coat.
After using it I can recommend it, but I believe dope is just as good if not better if you want a hard durable finish. The magical agreement with either Klass Kote or dope is "patience" and lots of it. You just have to make up your mind to take your time and wait for each coat to cure. I believe that Brodak's dope is made for them by Aircraft Spruce. I like it and plan to use it again on my next SPA plane. Having just finished the PRIMUS I am anxious to choose and start on my next subject. Are there any SPA legal planes that have elliptical wings and stabs?
Incidentally my next wing will probably be foam. I have a Feather Cut and have done a lot of wings in foam (when flying RC Combat you have to have lots of wings). A foam wing covered with glass cloth and fuse covered with glass cloth may be the fastest way to get a good finish with minimum steps.
