I want you to meet my little friend


#1

Here we have a PFG frame with a Microscisky v1.2, Chaoli (fast) 6mm motors, Crazepony FX806TC Tiny Whoop Camera, Crazepony 205 and 220 mah lipos and battery foam from a Crazepony whoop project that never got off the ground (pun intended…)
Sitting at AUW 25grams, it’s 2 grams heavier than I’d like it to be. I could probably lose the weight by getting rid of the grommets and motor plugs/connectors, I just hate using only double-sided tape as motor mounts.

I think I did reach the limit as to how low of a profile I can go. I love the COG on roll axis - very neutral feeling without the pendulum effect I’d get if the COG was off by placing the battery underneath.

The FC is mounted on non-conductive foam pad and ty-wrapped to the frame. I use the head of the ty-wrap as a post for the rubber band that holds the battery in place.

At the bottom of the post, I posted my config dump in case it might be helpful to you.

#2

Love that low rider!
What’s the flight time @chime13?


#3

@Kamsleo69 - I cap all my flight times to 3 minutes for 2 reasons - battery life and shaking hands :slight_smile:
But, I think I could get another 30 seconds out of it. At sea-level, I’m sure I would add another minute . At 8700ft, It doesn’t recover at all from a throttle-less drop but overall, flies really sweet.


#4

7mm build? what size motors??? looks awesome!!! :smiley:

i built something that looked similar to this yesterday… (didnt realize 2 motor wires were obviously touching each other due to ripped wiring ) it flew like a DREAM for 1 battery - then a fet popped and bit the dust… lol


#5

At 7mm, that thing would be outta sight at the lowest possible throttle setting! Lol.

Fantastic build @chime13! Find some cg023 props - they bite better than nanoqx


#6

Just updated the post. The motors are 6mm.


#7

I am so wanting anything but these damn nQx props! I have to look for the cg023 props. Didn’t know they existed. I do like the thought of 7mm though…never had 7mm motors - what size are the motor prop shafts?


#8

:smiley: SWEETTTTT how loud is it compared to 8.5mm set ups or 7mm set ups?


#9

Seriously, whisper quiet especially with new props


#10

have you flown it outside at ur usual area? how does it hold up with the wind? is performance as good as the larger classed motors?..

dammit chime you are making it very difficult to not get into a lesser sized motor class!!! :smiley: Ive been looking for a QUIETER but still very fast option lol


#11

The cg023 prop is just a little bigger and has more pitch than the qx. The cg023 itself no longer exists but the props are still out there. There us a re brand of it too that I can’t remember the name of that is still available too. Maybe someone knows it… 7mm motors are the same shat as 8.5. I’d say stay with 6 myself! 7mm motors also suck down batteries more like 8.5 than 6. @Bobnova recommends the syma x5 motors for cheap high kv. I’ve tried the 12’s before in a nano qx and it was insane, but didn’t rev very high.


#12

I’ve been pretty impressed by the x5c motors. Be sure it’s x5c though as x5 variants came with 7mm and 8mm!

They definitely eat battery faster than 6mm, but not as fast as 8mm.

With my ducted 3d printed 7mm I get 6 minutes on a 600mah, same battery in my q100 8.5mm is 3-4 minutes.


#13

Your wish is my command

It is capable of flying much better than I am…
more to come - in a hurry


#14

that thing looks like it flies really well dude… it covers a lot of ground for its size, and quickly too! You got me considering looking into a smaller class motors now lol I love the flying location… So chill, I just noticed the river in the back for the first time today.


#15

Nice build! And nice flying as well, I’d get pretty paranoid flying next to a river like that lol. Also check out the HM830 ‘paper airplane’ props, they are cheap, quiet and absolutely indestructible.


#16

@chime13!
That little bugger can flat out get it!
And you are far too modest, Acro, flips and a good tune. Very nice. :+1:


#17

I truly love the 6mm class of micro. I only wish there were more interest (parts) for this class. Being so light, they’re virtually indestructible . If tuned, it will be controllable in some wind. Weight is the enemy though and you notice every additional decigram. BTW, I notice ZERO difference among the Crazepony 220, Crazepony 205, and Nanotech 180 lipos. (damn spellchecker doesn’t like lipo…rather do lips - hahaha) So bottom line for me, I’ll stick to the Nanotech 180mah batteries and save a gram without losing any flight time.

@JBFPV - I’m as paranoid as it gets…I did already lose a kingkong100 with MMW motors to this river “Tomebamba”. The locals call the river “Julian Matadero” loosely translates to “Julian the killer” for 2 reasons: 1 during heavy rains, people have drowned there. Also, long, long time ago it was the backdrop for firing squads…Btw - thanks for the props, but we all know who’s “THE PILOT” around here - hahaha


#18

These motors have been in use since mid- December, They’ve been to the beach, buried in mud, and inverted under 3 inches of water, I’ve broken leads off the bottoms (and soldered) and they’re still going ~strong?
Anyway, I still have an unopened box of Spintechs that I brought over from the States - almost can’t wait to use them. BTW, at this altitude, the stock nQx motors are useless.

Thanks for the props - but I still suck (a little less, maybe ) :slight_smile:


#19

That’s a nice 6mm build! I have something similar with a Floureon H101 FC and spinning Bayang X9 propellers but haven’t flown it much.


#20

@NotFastEnuf - could you take a look at the video I posted on this thread and tell me what the little fluttering at some turns (~45sec and 1:10) and also when dropping(1:27) could be

Could you tell me if this might a tuning issue or just plain ol’ me ? Thanks!
