Weird things happening with me too...
I put a brand new PCB in my mQX - now my ORX-module binds in DSMX-22ms mode

Newer protocol built in or what happened?

From what I've seen in 4 years of flying HH 1s brushed UMs - there is no statistical difference in lifespan between any of the 8.5mm motors - regardless of the number of cooling holes or the color of the end-bell. Some last for hundreds of flights, others die before the maiden, while the majority are typically good for 100 flights or so. It is simply the nature of the beast when pager motors that are designed for extremely low-load, very low duty-cycle apps are used in high-load 100% duty-cycle apps such as aircraft powerplants.

Regarding reverse-rotation - you've had better luck than I've had. I tried running one of the normal-rotation motors in reverse on the Mossie when the Mossie motors were on backorder. It started acting up after only 20 flights, so I swapped it for the proper motor. Given the large variability in longevity even when they're running in the designed direction, it is impossible to determine if the short life was simply due to the normal variability that we've seen over the years, or if it was due to reverse-rotation. One would need a rather large sample-size to determine this with any confidence.

Well it might not have been cooling holes, but was merely a way to identify. I don't know if people still have this issue, but many of had black and white wire motors dying all the time and the red and blue wire motors having a normal lifespan, so in place I just run the red and blue motors in reverse. I'm not saying this works for all pager motors, but something about those red blue wire motors make them last really long.

Thanks for the brief on LVC, puffy batteries, maintenance, etc. With a plane and 2 helos, I've been delusional about keeping things blissfully uncomplicated. I see now that's not an option. Time to learn some discipline with the new Nanos that will appear in my mailbox any day.

First, I have to pay better attention to my watch. Without a nice feature-laden radio, I'll need to find a little timer at Dollar Tree to keep me honest. It's soooo easy to just keep flying, but you guys already know that.

And a decent charger that measures "put-back" is now a priority.

Too bad the blue light doesn't flash 30 seconds before LVC!

The shorter your flights the longer your lipo lifespan as a general rule! And dont leave them fully charged for long periods either. My electric bicycle has a $350 lipo so I take good care of that!

The mSR has only 8 cogs, if my weak eyesight is true, the mQX has 11 cogs. The mQX brass pinion looks bigger around and would likely need to be used on the mSR motor to work. Then there is that unsure matter of motor brush orientation. The brushes are flipped in the mQX motors for clockwise or counterclockwise rotation, (some have claimed some success running them backwards to their design). It might be worth a try if you are desparate and can make the pinion swap.

PS I would probably find a LHS near you that has the right motor with the correct pinion. My pinion puller is kind of iffy on those tiny motors.


I went to my LHS and picked one up this morning....installed it and I am in the air again!! Yea!

CAUTION:
THIS POST INCLUDES GRAPHIC DISCUSSION OF CAT PUKE
READER DISCRETION IS ADVISED

I usually leave my mQX on my kitchen counter so that it is readily available. BTW, I donít use canopies.

One morning a couple weeks ago, I found that overnight one of my cats had puked right on the mQX control board; he couldnít have hit it any better and he completely covered it. It was still very moist, and chunky, when I found it, there was just a very small area dried around the outer edges. So I realized the best thing I could do was to rinse it off under the kitchen faucet. So I did, and I rinsed it well. I even used a paper towel as a wash rag to get the crusty bits around the edges.Then I let it sit and dry.

It flies great.

Damn, I love my mQX.

My cat, well, he is on the s### list.

Humm, I'm suspecting that the cat my be jealous of all the attention your giving the mQX, and it probably doesn't enjoy getting chased around the house by it either. To be safe I'd recommend keeping the canopy on at all times.

I keep all my models away from the cat. Last thing I want is to have cat scent rubbed on them! Chasing the cat around with the mqx could be fun.

So now, your MQX has 9 Lives?

My mQX vibrates to no end!

Don't listen to anyone who tells you that some hot air can unwarp your props.

I've seen those props in so many of the videos here on the forums and on YouTube. I wondered how you could make them. Thanks!
