V-Tail Quad running hot

[Stone17]

Hi guy,

This is my second quad-copter I built.

The motor and ECS is running hot.
The motor is a Turnigy D2826/10 1400KV with 8x45 Props and ESC is a skywalker quattro.
Battery is a 3S lipo 5amp.

What should I do?
I use the setting David used in the Flite Test V-tail build.

What is your current draw?

most likely you are overpropped
specs from hk say 7x45 on 3s and 9x45 on 2s.
my sunnsky 1400s run pretty warm on 7x45 so i would guess thats your issue.

That 5000mAh 3S battery is pretty heavy. I'd be willing to guess if you went down to a 7x3.8" prop and a 2200mAh battery, you'd get a similar flight time with less heat.

Current is measured with an ammeter.
I was asking because I wanted to see if your props are to big or if weight was the problem but as 5oc said the specs call for smaller props and I agree with mustang, if you want to run big batteries you need smaller kV motors and bigger prop's
