Status: offline 		I have recently purchased a "Park Power 10 Brushless Outrunner" for my newly aquired "Gemini" by; Multiplex.
I am currently using a "Parkzone PKZ1030 11.1v 2200mAh 3-cell li-po. with a continuous discharge of 12c at 27 amps. I would like to know if I am using the best battery for the Motor stated.
As is, the plane flies ok, it just doesn't have the vertical performance I was looking for.
The AC in question will be used for Aerobatics and stunts.

Status: offline 		Well you left out two really important items to get an answer. Prop specs, and esc size.

Without these can't tell you what kind of amps your set up is drawing, and if it will work safely, nor if another prop selection might give you better performance.


Nice plane!

Status: offline 		I found an ULTRAFLY C-13/32 brushless motor on sale, at what seemed to be a good price. After reading the specs provided with the motor, I realized that I might be in over my head.The info provided with the motor says it is a sensorless motor and should only be used with an ESC designed for a sensorless motor. WHAT DOES THIS MEAN ? Needless to say, I'm new at this. Any help, many thanks.

In the future, rather than hijacking someone elses thread with your question, please start a new thread.

What does "sensorless" mean? It means that it is compatible with 99.9999999999999999999999% of brushless ESCs on the market. Really, sensorless is an obsolete term. Early brushless motor systems had actual sensors on them that determined which way the motor turned, and when to send the next electrical pulse to the motor to keep it turning.

Sensored motors had 5 extra wires in addition to the 3 power wires for the sensors. A sensorless ESC will work with a sensored motor, but not vice versa.

You will likely NEVER encounter a sensored brushless motor or ESC in your travels. They were never in wide use because of how expensive they were, and they've been obsolete for at least 5 years now.

Status: offline 		I found out what my problem was.
As I am new to (electric flight) I am the village idiot ......but I am learning.
The problem was not having the power I thought I should have had using the combo I stated.
However.....It wasn't the paring. It was the size of wires I was using.
I was putting a smaller wire (18 gage) onto a larger wire (8 gage). As an electrician friend pointed out.
So.....I was loosing most of the power available from the battery.
I fixed the problem.
Now.........I have a bi-plane ROCKET.
Pictures to come.
Thanks
