Hello all, I finally got my QR-1 after about a 6 week wait. I'm not new to helis, as I have over 20, 4 & 6CH helis up to 400 class size. As some of you were when this one was released, I was a little disappointed in its size, but got one anyway, I like it! I've gotten about 10 packs through it, including some non-Traxxas batteries. I have some Hyperion 240 mAh 25c batteries I wanted to try, and some 350mAh 25C "other" brands. I wanted to see if I could get some extra flight time with them, also, I attached a key ring camera with Velcro on the bottom. The cam only added about 16 grams to it, but shortened the flight time considerably. With the cam on, I get around 3 minutes, off 8-10 minutes depending on battery. I haven't gone to expert mode yet, but that's next, can't wait to flip it! Just a word to the wise, these are brushed motors, be sure to allow them to cool down between packs. It will lengthen the life of the motors! Good luck all!
