If you are in the market for a Tiny Whoop class brushed quad, check out the X1 from FPVModel, it's a pretty neat solution!

XRacer X1 Micro Drone Review -

Looks great! Im currently in the market for a new brushed micro setup. (Little bro is still learning and lost my moded H8 oh darn time for another micro )

nobody told me this hobby was a "collectors" hobby... I need one of these.

One of the biggest things that held me back from doing a tinywhoop when I got the bat was the rx and it was nearly impossible at the time to find an orangerx model for the taranis.

I think I'll hold off though... I've committed myself to building quad number 5... While this is kind of build it's really more "assemble" than build so I wont take the shortcut yet... but maybe after that I'll get myself one.

It looks like lots of fun!

That sounds like a fun little indoor quad!

One thing though... are you really, really sure that what you are saying about the motor placement is correct? The normal convention is that the motors with black and white wires should be run anti-clockwise and the ones with the red and blue wires run clockwise.

So for Betflight motor ordering there should be a red/blue wired motor at positions 1 & 4 and the white/black wired ones at 2 & 3.

They will still work if they are spun in the wrong direction, but they won't last very long as the commutator will be spinning against the metal brushes rather than with them.

Look really cool. Are the props the same as the tiny whoop? How strong does the frame feel?

Yes i am really really sure  this quad is a bit unconventional Maybe a mistake they make with the board, but it is what it is for now.

Propellers look identical
Frame feels strong enough for me, similar strength and rigidity to the E010 i would say... have been flying and crashing for 3 days and it still surviving.

So the motors don't spin in the usual directions for a quad running Betaflight?

Motors spin in the same direction as a normal betaflight Quad. My guess is they reversed the FET connectors for 2 motors. Not sure if that's on purpose or not.

If that's the case then you should just swap the pins in the connector housings.

The brushes on the motor are designed for a specific rotation direction. If you drive the motor in the wrong direction, it will last a very short time compared to driving it in the direction it is made to run. Here are the brushes from a CW and a CCW coreless brushed motor:





As you can see, the brushes point in different directions and it's the direction of the brushes that decide if the motor should be used for clockwise or counter-clockwise rotation. Of course, by swapping the polarity of the power, you can make it spin in either direction, but the brushes will be damaged if you run a motor in the wrong direction and the life span will be much shorter.

Usually comes with a power loss as well in my experience.
Idk if it has blackbox logging but I would be curious to see how the motors behave in flight. I had a random toy quad gifted to me once that had all the motor polarities reversed. After switching the hardware into an X5C shell (almost exact same weight, slightly heavier actually) and fixing the polarities I noticed a bit more punch (and the battery sag that goes with it ) but that was a toy and I dont have experience with a good brushed FC yet (soon though )

Interesting! I've never actually run my brushed motors the wrong way, knowing that it's not good for them, but it sounds logical that there wouldn't be as much power. If the commutator is spinning in the wrong direction, I reckon it'll make the tiny little brushes bounce more and waste power making sparks with each bounce.

Regarding the motors, I asked FPVModel and they said it's just the demo units that have this issue, production units will follow the traditional motor orders. I think it's best to follow their assembling instructions when it's live.

Here is their reply:

Quote:The first 20 fc had two of the motor plugs installed incorrectly.

This was making it so black white wires were up front and red black wires were in back.

On the other units the motor orientation follows the same motor direction as other quads
I had not noticed this until We sent out the demo units

I still want one... even if they goofed on the demo models!

but this is all the more reason to wait. Who knows what other small bugs might not be worked out in the first purchasable batch.

It's good to hear that it's just the demo units. They'd be saving up a mountain of hurt if there were thousands of production models out that would kill two of the motors in record short time.
