Build Comparison, newbie

Hi guys,

I'm looking at building my own quad or hex copter to use for training falcons. Minimal payload but want flight times out to 35-40 minutes if possible. Return to home is very important for what I plan to do, seems that's in all the flight controllers. I have been reading here and other places a while, just looking for some feedback on the two options i've narrowed down to and anything I might be missing. I have 25 year background in R/C airplanes, sport flying and racing and the last 5 years or so doing heli's. Still a lot to digest to figure this out! Have spektrum dx8 and several 6 channel receivers floating around in addition to some 6s packs and a good charger.

Option 1: (my first pick)
Tarot Ironman 650 Frame
Turnigy Multistar 4822-390Kv
Tz40A - HobbyKing 40A BlueSeries Brushless ESC
Tarot ZYX-M Multi rotor flight control
14x5 carbon props (not sure that's the ideal size?)

Option 2:
HobbyKing S550 Hexcopter Combo (Frame, ESC's and Motors) (ARF)
1 x S550 Hexcopter frame
6 x 2-6s 30 Amp BL Heli ESC's
6 x EMAX MT2216-810KV brushless motors
1 x 10x4.5 CW/CCW propeller set
Tarot ZYX-M Multi Rotor flight control

In either case, i'd be going go for the biggest MAH battery I can before weight becomes a negative to flight time. I was considering running option 1 at 6s as I have some batteries from my 500 heli I could use. I like the hexacopter because it has redundancy in case of failure and more payload if i choose to do other things with it. Plus that HK combo is cheap to get started!

I've also researched the eagle tree flight controller as I have someone local who can help with setup of that unit, but it's hard to ignore the price of the Tarot unit. I also realize the commonality of the NAZA units.

So any input for me? If there's anything else to consider, i'm all ears. Hoping to keep it at $500 or less, but tell me if that's not realistic.


Thanks much in advance for the help.

Generally for longer flight times you want to run large props (18 to 24" or more) and large diameter slow turning motors on a quad. The trade off then becomes a more "floaty" machine.

30 mins is probably near the upper limit right now. But others know more about this than I do.

I would agree on that 30 minute time. Even that's tough if you want a camera/gimbal, FPV etc. I have Tarot 680 hex that weighs 3 kg AUW and I get around 10 min on a 5000 mah batt with 13" props. The 10" props on your option#2 is probably a no go.
