Hi folks. I’m converting a balsa model to electric.
Today I got the motor for it, an Overlander Thumper 3548 900kv.
The spec sheet doesn’t tell me much about the power draw. So I need help with a couple of things.
How do I measure the draw of the motor, with the expected prop fitted? I have a multimeter, but is there some wiring harness I could make to measure the current?
Once I know what the current draw is, how can I use that to work out what battery capacity I would need? I’m going to run it on 4s, but not sure if I would need 3000mah or 4000mah to achieve around a 10 minute flight time.
