Hell, the motors are $9 each!!! You'd be better off just buying a BNF, no??

In agility mode I noticed one prop/motor was stuttering/surging, causing instability. I noticed it was also not tracking with itself, where all the other props had a nice flat profile in flight. To fix it I twisted more angle into the prop, instantly the stutter went away and now she flies like a dream. The stuttering was hardly noticeable in Safe mode, but totally obvious in agility mode.

So, added 2.7g, most of that is probably wires and hot glue lol
leds are Dialight
598-8220-107F Rd/Or w/ 100ohm resistor Port/left
598-8281-107f Green w/ 50 ohm resistor Stb/right
598-8291-107F Blue w/ 50 ohm resistor Front
And a 3mm Red / Blue Flash Flashing Water Clear LED (ebay) w/ 75 ohm on the rear

Side leds are just glued to the sides of the battery holder, front is semi hidden by the cano, rear is glued on the rear of the frame. Power I tapped off the main board (so using the flight lipo) W/ the glacier 160's I'm getting about 5:30mins to LVC


Very cool, thanks for the info! Are you tapping directly from the battery connection to the board or somewhere else?

I'll get video tonight.
Interesting, so is it throwing the nano in one direction, cutting throttle and basically letting the momentum carry it over? Looking forward to the vid.

Yeah $34 for a complete set, about half the price of a BNF. Pick up another one and just sell whatever you don't want/need.

How about Syma S107 main motors?
6x16mm - ~ 5USD a pair.

Well if it can flip in stability mode (only after changing limits to 150%) in your house, then it should flip even easier in agility mode, correct?

Some of us with regular controllers (dx4e) can't change the limits (devo 7E programmable is coming).

I was able to get flips fairly tight, but I was still 30 feet up doing it (agility mode high rates). And I wasn't consistent enough yet.

I'd like to learn to flip in house in agility mode then flip it to stability mode for recovery. Now that I soldered back in the button, rather than toggle switch, I'll have to practice (outside first).

Next will be flips while moving fwd/back/sideways, I think with this, that is definitely possible.

Good job!
Actually, even my regular flips with a gyros only quad end up losing plenty of altitude (not that fast on the sticks, especially during recovery).

By the way, some other micro quads with accelerometers (equivalent of stability mode) can also be flipped in a similar manner. I remember people getting a Hobby King Qbot-micro to loop by doing something like this.

Early in this thread are about 2 posts on some alternative 6mm motors to try:
1 person mentioned some 6x17mm motors at ~US$3 each used in a DIY quad.
I mentioned some common but powerful 6x12mm motors (4.5 ohms as I recall) that are available from a few sources.
Have not heard of anybody actually testing these on the nQx.

I thought the S107 main motors were 7mm and the tail motor was 6mm?

Would have to mod the motor holders if one were to use different length motors.

Also, when measuring impedance on these motors...I found that it changes as you turn the shaft of the motor. Not many people are aware of this, so it's hard to trust the numbers.

The tail motor is 4x17 or 5x15 afaik, but it is loong ago I laid a hand on one.

BTW here 1.95 a pair:

I have been lurking around this thread for awhile. These things really intrigue me. The weather in my area has been blowing like crazy for about a month. My fixed wing planes are on vacation till this wind quits. So I have been looking for an indoor/outdoor flying sports aircraft. Looks like these Quad jobbers may be the ticket for me. Being a total noobe with these quadracopters, I looked on my Real G6.5 sim. to see if there were any to try out. Low and behold I found a little "HeliMax 1SQ" quadracopter to try out. Starting out I was drifting around, totally out of control in a simulated school gym. After a few hours of practice I can now drift around the gym crashing about once every 5 minutes. Well, this inspired me to order one of these Nano QX's. Seems these little guys are a good way to start out. I have one question for you established flying quad jockeys. Dose simmy practice help with flying these guys? I got where I can flip the little HeliMax 1SQ and regain control most of the time. I just hope the Nano QX is as much fun as the simulated HeliMax.

Just received mine last night. I have been flying it around my house and yard all day. This thread is now many pages long so forgive me if this has been asked already. Has anyone tried to set it up for night flying? I think it would not have enough power for LED's, I was thinking a few stripes of luminous paint?

There are some articles on this (by Gordon Johnson,as I recall, talking about coreless motors for micro airplanes). My memory is that the numbers change as you turn the shaft because sometimes the brushes will connect multiple coils on the motor, and that the number that you want is either the highest or lowest, I forget which.

I use a different sim and have different quads, but sim practice does help for me to practice the sequence of the hand motions involved: I lower a bit, but not all the way, the throttle while the quad is upside down during a flip.
However, how fast a quad flips and how much it falls during a flip can vary from a sim to a real quad, so best to start really high on your first flips until you get a sense of how much altitude you tend to lose.

Sim practice helps mainly with orientation. You should be able to jump to a quadcopter after a little bit of sim time.
