Thank you Minime, but I have a confession to make I actually uesd to build and fly r/c aircraft, still fly now and then, and only got into this part of the hobby because of my ex. She always wanted a puffer built for her, thankfully not the one pictured here. By the way the lights on both the puffer and the drifter work and I have even sailed the puffer at night just for the experience. My standard of building is getting better so obviously the more you do the better the quality becomes.
