Turnigy Talon Hexcopter (v1.0) What to buy

I never mention about modifying firmware of ESC (is it possible at home?), i only changed firmware of multirotor board.

And i talked with Ia, he said i can warrant fried motors. But will send those all back, i dont trust those :(

Please guys, what are you using for your Talon? I have v3 brain with sexycopter fimware and NTM Prop Drive 28-26 1000KV / 315W motors with Turnigy TY-P1 25Amp HEXFET®* Brushless Speed Controller ESC My problem is: i fried 3 motors already (in process of throttle range setting). When i changed motor and ESC, after one week one of the motors wont spin and was beeping like it was not set (no confirmation melody), i tried to set throttle range again (with zero yaw setting) and that motor fried again. So what is wrong? Motor, esc or brain?

i poster this twoce in talon discussion and it was deleted twice.

I wanted to warrant esc and motors i bought and got this silly repy from Ian Supprot member:

I am sorry but you have modified the ESC firmware and as a result we cannot grantee the ESC will function properly. This can burn and ESC's if done incorrectly.

Sorry but we cannot offer your warranty in this instance.

Do you know how to escalate this support issua to someone more clever?

Thanks

Rather than use a power distribution board, make a harness with 6 deans or XT60's (or connectors of choice) This way you can still unplug a single boom at a time. I use this technique on mine and it works really well. All the power goes to the underside and all the signal to the upper side where the controller is. one less level of stack on the top. This is assuming you are pulling a reasonable amount of current. Make a cover plate for the underside that hides the loom and doubles as a Lipo mounting plate stood off with some hex standoffs.

Another advantage is you can unplug a boom and hook it up to a RX and Lipo to run independantly for ballancing etc.

By the way if it's a large multirotor having overpowered ESC's is ok. My quad runs 14x4.7 SF props on 800W 3548's on 4S via 60A plush.

If you read the details on that motor's webpage, they give amp readings for 3-cell and 4-cell batteies on various size props. Here's the bit that will interest you:
10x5 - 11.1v - 200W - 18A
10x5 - 14.8v - 385W - 26A

It's not a bad idea to allow some headroom so your ESCs aren't getting overworked, but I think 30A units will be heaps enough - especially if you mount them on the frame where they will be cooled by constant prop-wash. I'd suggest the 30A BlueSeries unit would be an excellent choice - these are re-branded Mystery items and in my experience they perform very well. They're also much cheaper than your previous choice, they are rated for 40A burst, they have lots of programming options and they only weigh 28 grams each. http://www.hobbyking.com/hobbyking/store/__13429__HobbyKing_30A_BlueSeries_Brushless_Speed_Controller.html

Thanks Klaw81,

With the ESC's, for good measure I took the max current for the motors and added 25%, which = 40A. The 45A trust ESC's are the lightest 40/45A ESC's hobby king carry, except for the 40A SuperBrain which get poor reviews. ECalc also agrees with you and suggests the max current per motor is 23A, so I might look at 30 ESC's.

With the weight, I quoted the wrong figure. Total weight for 2x batteries is 1452g. So the estimated times should still be correct.

I also have the control board and left out the other secondary bits and pieces from the list as I am looking for feedback on just the drive part of the setup.

Thanks again for the help!
