They have CW and CCW for a reason. It depends on how the finger brushes lay on the armature. Run the wrong way and they will not last long.

I'm not sure how long the motors brushes would last if spinning the opposite direction intended. I haven't taken any time to experiment with that, but I remember a few folks unhappy with the longevity of some Horizon/Blade mQX motors and trying the opposite brushed version. As I recall some had reasonable success, but as flimsy as these pager motor brushes are I would not expect the same results when spinning towards and pushing the wiper/brushes into their mounts.

I also would not want to experiment with trying to stuff a 7mm X 16.5mm motor into the flimsy frame of the Proto when the mounting holes for 6mm X 12mm are already making that area the weakest point on the whole quad. But enjoy to hear how and if that works out. You are also talking about a 2.9 gram motor X 4 vs 1.3 gram motor X 4 weight difference. Oh Well.
I anxiously await your results.


But ENJOY every experiment as if it may be your last.

You clearly haven't seen how many of my previous experiments have turned out... ::cough::lawn darts::cough:: But I learned something about every crash!

I don't think I'd call the motor mounts the weakest part of the Proto-X, and I certainly wouldn't call it flimsy. I got caught in an updraft outdoors, lost control and it fell about 30ft onto asphalt; no damage. I was able to buffer it a little with some last minute thrust right before impact, but it felt the majority of the fall directly. Pretty tough little bird. If anything, I'd peg the motors themselves as the weakest link in the whole system, besides having a loose mount.

Also, I wouldn't stuff the bigger motor through the original little hole, I'd probably figure out how to just mount them on top of the frame (hotglue to the rescue)

Another challenge would be fitting the props onto the 1mm shaft; I don't think I have a 1mm drill bit...

Maybe I'll get some play-money for Christmas and try it out. Heck, if it works, and produces more thrust, we may have a candidate for Tiniest Quad-Cam! (hey, I can daydream)

FYI

Even THiS much adjustment helps!!! I may glue them there. Just carefully pull them up.

The use of the large-er batteries was more of an experiment than anything just to see if they would work. Since having found the Hobbytown Ares 100mah battery (with wire & connector configured RTF) I tend to only use them now.

Having said that, when using the BIG batteries that hang over the front... I needed to compensate by clicking the rear trim to balance it out in a hover. FYI when using the largerest 200mah, it took as much as 18 clicks to the rear to trim it out

BTW I realise I could have turned the battery sideways and mounted it that way (with making a longer wire) for better COG but it wasn't worth the effort at the time... just buy the Ares batteries and you'll simply have plug & play.

Hey pilots, anyone know where to buy replacement propellers for this little quad yet? Too many back pages to read through! Thanks everyone!

I could not trim/stabilize my Proto X quad. Hobby shop folk checked mine out and attempted to fly it and finally determined that the stabilization system was not working, gave me a replacement Proto X quad that is more stable and controllable.

Something I didn't know being new to quads: The black props on the rear and gray props on the front have to have opposite pitch. Look at a new quad as it comes out of the box. When replacing a broken or missing prop, be sure that replacement has pitch opposite to the other one. Black props to the rear and grays to the front. Props are marked A or B (hard to see) and should be installed per the drawing in the instruction sheet.

BTW, I'm still stuggling with my replacement Proto X , have not been able to trim it for steady hover so far, getting lots of exercise moving furniture to retrieve it. The Hubsan X-4 or other compatible transmitter would probably make it easier to control.

COOL TOY !

Got mine on Sunday ; can't charge it Fast enough ; Best $29.99
i ever spent and I'll be doing that battery Mod soon !!!

I figure that if i take some 12K carbon tow with saturated epoxy
i can wrap this thing just like the circuit board does around
the motors. That board is Heavy, the 12K ain't. I could add 25%
to the diameter, and still loose 0.25g over-all ; i'd twist the carbon
to get rid of epoxy, and tighten the fibers together.

http://www.acpsales.com/OnlineStore.php?cat=4958

Another option is to braid three tows of 3K together ; the braid
would be stronger than the 12K twisted, so Ya need Less of it ---
it's a Better fiber arrangement

Did Ya know that carbon is a conductor ; or place your wire inside
the braid and isolate it from the circuit board . Speaking of braided carbon sleeves ; this place has a 1/4" sleeve of carbon, that will pull down to 0.09" diameter when stretched.

I fly mostly medium sized .homemade. .stuff, and the Proto-X blows my mind! Add to that, it flies pretty decent.

However, I would really like to try a hubsan controller, as my mini doesn't engage the yaw until the stick is thrown past ~50% of TDC on the left and around 40% on the right.
