Powering Archer Plus SR6 Mini

[CrashGuard]

I've been using Frsky X18s for around 4 years and was curious about the Archer Plus SR6 Mini that was added into the X18's update. I want to go small (indoor micro) or low power using the common brushed 8520 motor. So how should the power distribution be implemented? The two motor pads are large enough to carry 5 amps each as stated, but where does it get a total of 10+ amps from? The tiny pad next to channel 6? (Really) I tested a motor using a fully charged Lithium Ion @ 3.7 v and a standard toy prop and got 4.6 amps draw.

That tiny motor screams with only 3.7 volts and is only rated to 5 volts. I could go 2S Lipo but that would be too much. Perhaps, that is what min and max throttle is for. I don't know. Any ideas would help. I thought of using the 14 amp SBEC Neutron on 5 volts, but I'm not sure it will play nice with 2S because it suggest having 6 volts above the output voltage. Hum...

Also, it would be nice to know if the motor outputs are PWM or DC FET regulated.

Yes, you are going to be putting power in through the positive and negative pads next to the 6ch channel signal pad but you could use a micro brushed ESC, such as this guy (seriously these are TINY yet they still have a BEC) https://gravesrc.com/csep7p-castle-...ro-esc-prog-xx/?searchid=0&search_query=pixie Use the adapter cables the receiver comes with to convert the servo plug that comes installed.

Thanks Jarron for the link. That would add brushless ESC to the SR6 Mini, but I have the SR6 Mini-E which has two built-in ESCs. I was not clear. I think the Neutron 14 amp is what I need to power it but Aloft is sold out. I want some other things from there and ship it all together.

The ESC I linked you to is a brushed ESC. The Neuron 14A does not function as an ESC, it is a step down voltage regulator.

The 8520 motor comes in 3.6 volt and 7.4 volt versions. You might want to see if the motors actually produce any more power on the 2S before going down that path.

(Research shows the 7.4 will run hot and burn out.)

So running 1S with the 8520 would be the best bet, and your current receiver can power that just fine. No need for anything else. If that is not enough power, then you can switch over to a little brushless setup, or a larger brushed motor.

Oops, there I go again; I meant to say BRUSHED. The 8520 motors were advertised as 5 volt max. Okay, I'll try 1S.

Seems to be advertised at different voltage ratings, but probably save to say that they are all the same, and probably the lowest voltage is the reality.
