I built this guy out of PVC plumbing parts from Canadian tire and an old plastic food container:
30 deg V
10 x 4.5 propellers
D3530/14 1100kv Motors
30A HK ESCs (SimonK )
APM 2.5 brain with 915 Radio + GPS
(arducopter 2.9.1b modified to support my VTail mix)
4000mAh 40-80C nanotech battery (I like them for my Stampede 4x4)
all up weight is about 1500g (1760g with my 'trainer landing gear' shown above)
Hovers at 25A / 45% throttle and gets about 7 min flight time
I also added Mavlink support to my Turnigy 9x. Currently I forward mavlink data from my PC over bluetooth, but I hope to put a 3dr radio in place of the bluetooth to avoid the PC. The screen I added provides battery Amps / Volts / % Remaining (with warning beeps), flight mode, satellite fix / count / hdop and my favorite feature: distance from home and bearing offset to get home. 0° means fly forward to get home, 180° means fly backwards to get home - handy!
This was and continues to be a really fun project!
