What about epoxying in a piece of all thread, 5/16″, and stacking washers on this. Then you can tailor your nose weight to what you need, and be able to have a way to do tracking in the future. You…   Read more»

Both stick really well if the surface is clean. I would wash the surface with warm soap and water, then afterwards you lacquer thinner or alcohol, allow to dry and then use your foam. I use ethyl alcohol most of…   Read more»

I have both types of foam, but is there an issue with adhesion to the cone wall?

Another reason for applying it in layers. A little at a time. If you allow it to expand in thin layers, you keep it from getting dense or too dense. I used it to seal a dog house and in…   Read more»

I would caution against the “Great Stuff” spray can foam.Most (but not all) of the spray can varieties rely on exposure to air to cure, unlike the epoxy-based 2part foams that (justifiably) cost a bit more. The problem comes when…   Read more»

Greater weight, less volume. Therefore, as you establish your center of gravity, you can get more weight further forward, moving your center of gravity further forward, making it so you do not need as much ballast. In some events, this…   Read more»

thanks for the practical info Bear. But what’s the reasoning behind the sinker vs. the BBs?

Dave, may I suggest that instead of using BB’s, you go to Wal-mart and buy fishing sinkers in sporting goods for your ballast.While you are at Wal-mart, in the home repair area, you can get an aerosol can of foam…   Read more»

Since I did not fly last year, I have to make up for lost flying time. So, I will be happy to help with LCO/RSO duties after I get my first 30 or 40 flights in.

Weather looking really nice – waiver has been called in – Saturday should be awesome! Figuring we’ll need four low power and probably four high power and adjust accordingly from there. I’m bringing the PA – thinking we might need…   Read more»

Just found out I do not have to work till noon Saturday.See ya all there.

What Mr. Ed said. If the weather cooperates, we’ll plan on flying from about 9 AM till about 4PM or thereabouts, depending on interest, motors and the weather, and that should allow enough time to put stuff away before the…   Read more»
