I recently picked up a syringe of Chipquik SMD291 tack flux to play around with, I'm just getting into doing smd stuff... and I find myself using it for just about everything because it's so easy to use, works a treat, and is fairly easy to clean up. What flux do you like to use? Do you have different ones for different uses, or do you tend to just use one for everything?
The planes have extra radar reflecting thingies bolted on that make them show up real good on radar so the true radar signature is obscured (also a good idea for air traffic safety reasons), but they can be quickly removed for combat.
