Hello guys,

I'm trying to set up a DIY drone, and I'd like some expert advice if my config is good, or if you have some (cheap) optimizations to do!

I've already ordered the radio (classic FlySky FS-TH9X 2.4G 9CH)

Thanks a lot!

A little cheap, but no real complaints. Might suggest a 3S Multistar 5200mAh battery though. Also don't forget a charger

Thanks for your answer !
Like this one ? http://www.hobbyking.com/hobbyking/...apacity_3S_5200mAh_Multi_Rotor_Lipo_Pack.html
It's only 20C at peak... Isn't it too low?

Any other optimization?

The charger is also on its way

Yes, make sure you are getting the 3S1P version (which is the one you linked), as the 3S2P is a little shorter, but twice as thick.

OK... So with this battery I can discharge 52Amps. I don't have any precise specification for my motors but I know the recommended ESC are 18 Amps, so I need max 18*4 = 72 Amps.
Will that do the trick? Apparently my motors will never reach the maximum of the ESCs!
Thanks again for the clarifications.

You will likely not use the full power of your motors for very long, but you might be better with a 5Ah 20C

I looked again but couldn't find any maximum amp for those motors...
So should I take the 3S Multistar 5200mAh battery anyway or should I take another one with 20C?
Knowing that I may later need to plug in other devices such as a FPV camera...
Thanks for any other suggestion of good battery more adapted!

Well the prefered C rating will vary depending on the capacity, 20C for a 5000mAh battery would be great. You could likely use the 5200, but if you are flying it hard or heavy your battery will not last as long.

OK I ordered 2 batteries:
- Multistar High Capacity 3S 5200mAh 10C
- Turnigy 5000mAh 3S 20C Lipo Pack
So I'll know what works the best for my next batteries... because they don't last forever!
Thanks for the tips.
