my watt meter shows 1090 watts @ 90 amp
i needed to find out if with changing prop i can keep the amp with about 1200 watts.
Your results are interesting. But I think something might be wrong with your setup. Do you have the batteries in series or in parallel?
You are getting a 90A load with an input of 1090 Watts. Do you happen to know the RPM?
The Aeronaut diagram for the 15 x 10 folder shows that prop using 650W at 6,500 RPM. And the Hyperion test data for your motor
on 3S and with a similar sized, but slightly smaller and non-folding prop, as:
I can't understand why you are getting current readings that high, but you are already well over the 65A Max Current rating for that motor and I would think it would be overheating now.
I have used a few folding props, none that large through, and have generally found them to draw similar amounts of current to what would be drawn by a similar sized fixed prop.
