My Tiny Whoop only flies for 10 seconds - HELP?!?!

[TrixFPV]

I bought a Blade Inductrix and upgraded the motors to Tiny Whoop 19,000Kv, the batteries to Nanotech 200mah 35c - 75c 1s and added an FPV cam. It flew ok with no mods but now it will only fly for 10 seconds before it plummets to the ground. When I check the batteries the voltage is 4.00v so I can't understand why it won't fly. Can anyone help?!?!

Those motors draw 2A each! You need motors more in the 14,000Kv range.

Trix, what's your all up weight?

Did you break in the new motors (low throttle for 3-4 batteries) before going all out wide-open throttle?

Where'd you pickup your 19,000 kv motors? (What brand)

Do your batteries use the stock inductrix power lead (super tiny micro plug)? You'll likely want batteries that have a JST-PH-2.0 plug to deliver the amps needed for those motors.
