Pretty much all the parts on the V929 are usable on the MQX, as someone has stated it's only the centre hub that's really any different.

I've bought a full set of V929 landing gear for mine as it was the same price to buy 4 of them that 1 MQX replacement.

I also think you can buy the booms with the wire pre-installed....I hope so anyway as I am one of the worst people in the world when it comes to soldering and those wires are tiny!

Next time anything breaks on my MQX i'm just gonna buy a BNF V929 and stick the centre hub and board back on ebay, all told it'll probably cost me about 16 or so for a full set of spare parts.

Nice!
And I had the same idea of grabbing a BNF 929 for $32ish for parts for mine as well.

Odd unexpected item of the day:
Here's a fun shot (high in fiber & good for you).
This is a slice of about 1/4 of a peeled away piece from an mQX carbon arm.
I ran current through a small section of it (around 30amps) getting it yellow-hot and burning away all of the resin or binder that is used (I'm curious how they bind that stuff).
As you can see they pack a LOT of fiber in there!! this would have been 4 times bigger if it had been a whole piece of arm and on a 1/4 section sliver. :-)

Looking good, like the easy to track canopy shape.
I was considering a paper snap-on tail for better visibility further away..
Would probably limit me in fast backward flight but I'm not going to do that way far away as much.
Right now sorta sticking with my beat-up stock canopy because I have a few holes drilled in it and Bright LEDs and wiring all mounted to it.
Looks like I could have a LOT of fun with a color printer and paper canopies.
My next design may involve rigidly mounted LEDs on long solid wires that 'stick out' the top or forward the canopy. or go out on tiny carbon shafts just for LED mounting.
I do a lot of night flying.

And I completely 'ran out' of brass pinion this evening :-(
That blows.
The other 3 are soon to follow.
I'm not sure if there's a way to just change that gear.

It is possible to change the pinion, it is finding the right tools to do the job that makes it difficult.

You would need to find a replacement pinion first off.

Then a tool similar to this one would be a great help:

The shaft on this one is 3mm so will be too big so you would have to find a supplier that has a smaller one

However if you could support the underside of the pinion you could use a small diameter pin and hammer to knock the motor shaft out.

Very fiddly, but do-able

Wow, how many flights do you have on that motor? None of mine have ANY visible wear. And was that running with a plastic gear on an mQX or something else?

Anyone who was wondering about replacement carbon booms that have the wire pre-installed, the following item, though lacking any decent description, the seller has said is as pictured, so includes wire.

Thanks! looks like different connector toward the controller board so might still need to do some soldering & shrink if used on an mQX.

And re: above.. I've been flying a whole lot since I got it two months ago.
Pretty much whenever I can.
I am limited to two batteries that it came with and I've not bought any more yet.
I expected them to last longer than this, outlive the batteries and the motors at least.

They didn't show any visible wear for awhile, then about a week ago it slowly started getting very noticeable I think it reaches a tipping point where they start wearing out much faster.
So a little tiny bit of wear over time then the teeth weaken and really start to go.

OK, I think I am getting bad motors now. I can't have more than 30 flights on this thing. And the front left motor is weak, the quad slowly leans in that directions, and it fails to keep up when I punch it. I does not make sense to replace just one motor, do you guys change them all at once? I am thinking about getting V929 motors to replace it with. If the Blade ones are that poor than they don't deserve to sell me the spares. Also under some punches the quad drops as if it experiences a brownout. Do the bad motors cause this? Should I email Horizon Hobby and see if they will send me some motors.

Make sure your battery connector (both halves) is clean and OK. Some DeOxIt would help. That JST connector has been troublesome under 2A loads for more than a decade. We used to replace them on the Piccolo because they actually got hot at 2A. Heat = wasted power = lost voltage.

Thanks, will check that. Need to add DeOxit to my shopping list. Where can it be found?

The MQX motors are too expensive, I am going to order 2 A and 2 B motors for the 929 since they are supposed to be identical. I know they plug in under the covers and they probably won't match so I'll need to mod the MQX to take these new motors. What have you guys done?
