I really like flying things, so when copters became more accessible it was just a matter of time to build one.
This copter is built from ready-made bricks. KK2.0 from HobbyKing is used as flight controller. It works really well form me. Setup was pretty easy - if I recall correctly I didn't perform any PID tuning at all. Motor controllers are 30A ESCs with SimonK software from RCTimer. They are a bit too big for used motors, but that's not a problem (except for slightly larger mass).
Three cell Lipo batteries are used to power this copter. I use a few different capacities: from 1800mAh up to 3600mAh. Flight time with bigger battery is around 10 minutes. Power distribution is done via frame base plate with dedicated power tracks- ESCs wires are soldered to solderpads. This type of power distribution really decreases amount of tangled wires in the copter.
Assan 2.4GHz RC system is utilised, I mounted 6 channels receiver (X8R6M) onboard. This RC link works realiably and I never had any problems with it.
Q450 frame from HK is used. I chose 2830/11 1000kV motors from RCTimer, they provide enough thrust for dynamic flying, although I may get this copter to fly faster by using 4S battery (both ESCs and motors can handle it). I'll probably try this idea out, just to see how fast it can fly ;)
8x4.5 propellers are used. I broke quite a few of them so far, but fortunately there was a discount on RCTimer so I bought a whole pack.
