I agree.... Spare batteries are a must ! I also did the same for the weight loss in the rear... Also by making the boom shorter, not only do you lose the weight, but it also makes it a bit more rigid and stronger, as the longer that boom is the more flimsy it will be and the more likely of it breaking off from any crazy flying tactics that we may throw at the MCX... Glad your enjoying it... I have the funnest times with mine also ! I keep glancing outside for the last few days to see if the wind has calmed down so I can take mine outside again, since I've tweaked with it some more... I'am really gonna launch this sucker hard when I do...!...LMAO...


Take care feller,
