Affordable electronics for bully 2 moa

[sekk_sekk]

Hi everyone, my first post, my first crawler, my firs rc car!!

I'm looking for affordable (but not so bad) electronics for bully 2 moa. I was thinking about:

- Radio Flysky GT3C hacked with GR3F receiver (it seems it can go up to 8,4V)
- 2 Hobbywings QuicRun 1080 (working with 2s and 3s lipo, BEC voltage switchable in 7,4V and 6V)
- Servo Power HD WP-23KG (working at 6V, waterproof with titanium and steel gear)
- 2 Snow phanter 35t motor

Question: Does a 2s lipo 850 mah 70C give enough W or i need to mount a 3s lipo? (durate time is not a problem)

I asked to Hobbywings costumer service most "confortable" configuration (BATTERY/ Voltage BEC) and here's the answer:
Because it's switch mode BEC,so very less difference of effiency between 2s or 3s,6V or7.4V.If you so care about this,6V with 2S will be most effiency.

I asked for dual esc wiring too and here's the answer:
With same voltage of BEC output ,I think it's acceptable.But just in case, take out one of the ESC's red cable of throttle wire will be more safe.Because different voltage between BEC may damage the BEC.

Thnks for helping and great forum!

NEVER HOOK UP TWO BECS TO ONE RECEIVER! They never play nice together. I would run 3s and gear the motors down. Your gonna pick up torque, low speed control, and still have faster wheel speed when you need it. It may even run cooler depending how you drive and what gearing you choose.
The bec should not have a problem with 2 or 3s. If you burn one up its probably not able to supply enough amps for the servo.

Isn't correct this configuration (type2)?

Do you see the note they put about some manufacturers say to take one of the middle conductor out. That means one BEC. Its a safer bet and your not gonna have a problem if you take one off.

i'm not sure you can mix motor power. It's not a dual channel esc.

About dual channel esc:
Do you really want a dual channel ESC?

With Gt3c haked transmitter i hope i can do a complete mix of 2 channels so i prefer a solution with two normal esc
