Last question before I purchase my parts and officially join the brushless squad (maybe unofficially till I build it )!
I’m building a brushless quadcopter with EMAX RS1106 4500KV motors and GF3025 props. My 4 in 1 ESC is rated at 15A.
My build will weigh approx. 75g without the battery, and can generate approx. 265g thrust per motor with a 3S battery @ 8A draw per motor.
Three quick questions about battery choice:
- Should I get a 45C battery or a 75C battery? Is 75C overkill? (450mAh45C = 20A) (450mAh75C = 34A)
- Should I get a 450mAh (43g) battery or 650mAh (59g) battery? Will this give me longer flight time because I think I’d have a good thrust/weight ratio either way?
- Should I get an expensive Tattu from genstattu.com or a cheaper Turnigy nano-tech from hobbyking.com, or is there a different brand you guys can recommend? I’m fine paying a lot if the batteries will last a long time, if I treat them well.
The 45C, 450mAh tattu is under restocking till mid-september…
