Nick... what motors / power / prop setup are you looking at?
Pete
Pete,
My estimated weight, with camera will be 4.4kg. This includes 2 lipo's, gimbal, camera and electrics, so AUW: 4.4kg. Given I am guessing on this, specs of all items calculated together, I can be over by 600g and still get 10 mins flight based on this configuration:
Motors: Tiger MT2814-10 (770kv)
ESC: Turnigy 30A plush (new chip) stock, not flashed.
FC: ZeroUAV YS-Y6 with GPS, and 16 point waypoint, 900mhz Datalink
Battery: 5000mah 4S (35c) x2 Total 10,000mah. I have 10 of these, for 5 10 min flights. I can balance 4 at a time from the car battery.
Gimbal: Photohigher AV130, with Skyline RSGS
Camera: Sony PJ710V (PAL) with Balanced Optical Steadyshot
Props: Have the following to test in hand: Graupner 11x50, Turnigy 13x4.5 Wood, Gemfan 13x4'5s Wood, Gemfan 12x4's Wood
I'd say the Gemfan 12x4's will be the best, safe for full throttle, but the Gemfan and Turnigy 13x4.5's show a little over limit at max throttle, but shouldn't be an issue. The 13's will give me hover at 47% throttle (lets just say half stick) and the 12's boost the throttle to hover to 63%. I think this may be a winner (12's) as I'm on 10mins flight, and chopping the air at higher rpm in my opinion makes the craft a little less suitable to fluctuations in air-pressure (steadier as its higher geared corkscrewing).
The YS-X6 is known to handle all prop sizes really well (favors larger), so I'll test with 13's first, and if its steady, I'll fly about 10 flights with no gimbal to see its stability. If its good, I'll load up the gimbal (so easy on the XM-6) and see how it goes.
The Tigers I have are excellent, and although I'd like the pricier AXIS motors, I simply cant afford to shell out the money for a different logo. I dont see a big enough difference in performance in them to justify the upgrade just yet.
