Simple question about batteries and connectors
 

Hi there,

I'm making a simple little plane with my son, here's some questions we have:

1) Our motors are wired with no connector (2 wires), what connector do we need to put on the motor wire to be able to plug it into the receiver? I'm guessing it's some kind of JST plug? But what?
2) The motors we have are 3.7v. What's the best flat battery for these? Is Lipo the only flat battery option? Or is there something else?
3) And if we plug one in to one socket of the receiver, and one in another socket, will the motors be wired in parallel?

See attached pics to see the receiver we have, and the motor. Thank you!

Hello!

First thing , you can not plug the motor directly into the receiver. The motor needs to be connected to a brushed electronic speed control (esc) and the esc is then plugged into the receivers throttle port (#3).
.
As far as the battery ,if the motor can only accept 3.7 volts you will have a problem (as jester pointed out below) in that receiver needs at least 4.8volts to operate.
The ultra-micro receiver/esc boards(bricks) would be a better choice for that motor but for a few dollars more you can buy a complete micro plane ready to fly.
Either that or go with a larger motor, 5amp esc, and a 6 volt battery.

Good luck.

Can that receiver work on 3.7v? Most won't. I'm going to suggest that you build something from plans that a designer has worked out and experimented on to get the components right. Since you are doing this with a young one, it's important to be successful on the first try. I'll syggest a plane called the Blu Baby. It's bigger then what you were prepping for, but bigger is good for flying. The components won't cost much, and the flying characteristics are as gentle as they come.

Yes, as said above, you would need a low voltage receiver and a brushed esc. If you don't have those, than you really should look for a new plane that's a bit bigger.

As far as the battery goes, lipo isn't the only option, you can also use lifepo4. BUT, they are heavier, and herd to find in 1s, so you would have to un solder the cells. So, lipo is likely gong to be the only option for a plane of that size.

For a first project, build a Blu Baby 33 inch. It's cheap and flies pretty well.
