I've been putting some time on my new Quad prior to converting it to L1. The PID's need to be tweaked a little but it fly's pretty good overall. The bottle weighs 510 grams and is hung on the landing gear which is at half the boom length. I was a little timid on putting on the weight the first time but it handles a 30 percent increase in weight half way out the boom
fairly well. When I picked the bottle up off the ground it took 3/4 throttle to get it up. It would hold position better if I was out in the open. I new the outcome may not be good at the end but just had to see.
