Of the two Chameleon frames I've owned, this is the first one I bought, the most abused and the only one remaining. The second one met an untimely end in a creek on its maiden flight. Ol' faithful deserved an upgrade and I also wanted to put it on a diet to try to get closer to 600g of AUW. Thanks to some modern bits and pieces, achievement unlocked. She clocks in at a svelt 604g compared to the original 650g or so. This is largely thanks to the awesome new MB Primo motors and moving from individual ESCs to a 4in1.
