Walter, The new Zagi 2000 airfoil is very similar to the Boomerang, so yours should penetrate as well as the 'rang. Perhaps your CG is too far back? I fly mine a bit sensitive at 7.5" Most people fly it between 7-1/4 to 7-3/8" back from the nose. I'm not sure what the Zagi folks recommend in their instructions, but perhaps this is the cause. As for ballast, if there's enough lift to for you to climb, you can add ballast. However, I have had the Boomerang ( and it was a very light one) in 30+mph winds with no ballast with no problem. Ballast just makes you retain energy better and improve your speed a bit. For combat, the added speed is unwanted. It makes targeting your opponent much harder, because you have to PRECISELY calculate your closing vectors. If your wing is approximately the same speed, flying a tight pattern is easier and you will get your kill that much quicker. Another issue about penetration, are your throws too much? I use a lot of aileron, but I have TONS of exponential to soften it up. Flying with just enough deflection to induce the turn is very important in preventing the elevons from stalling the wing. I fly elevator with very little throw, but almost no expo. Frank Cavazos recently showed me how to mix Rudder coupling into my Futaba 8U, and that's a really fun setup. I get twice the aileron throw using the rudder stick. I like diving in on my opponent in a reverse immelman with several snap rolls on the vertical leg. Why? 'cause it's fun!
