Due to the cold weather, I picked up a Blade mCX2 helicopter, and wow is it fun! I suck at flying just as much as I suck at driving - let's just say my cat and dog find somewhere to hide pretty quick when they hear/see it - but it's still quite fun.
I've only had this thing for about 2 weeks and I've already had to replace both spur gears; I landed hard and one of the motors slid down in its holder causing it to touch the other spur gear.

I got tired of taking off the rear canopy to adjust the motor (have since shoe-goo'd it in place), so I tried using a boom tail part (whatever it's called), but the heli wants to fly forward now no matter how I trim it. Not sure if it's a weight/balance issue, but I had to put the stock rear canopy back on. Oh well.
I modded the charger so that it charges at 120mA instead of the stock ~200mA to keep the charge at 1C. And since the charger seems to eat AA's, I made an adaptor out of an old Nintendo Gamebox supply (it only outputs 5.3v @ 200mA but it's close enough). I then made a series adaptor thingy so I can charge and balance up to 4 packs at once using my Xtrema charger if I'm in a hurry.
Man, these batteries are small! I feel like I'm going to break them. I had gotten two extra Turnigy batteries, but one was weak so the LHS replaced it with a EFlite one at no charge.
