mCPX after market parts: EPIC FAIL!
Dont get me wrong, I love my mCPX. it gets more flying than any other heli during winter. But it has its short comings. These have all been beaten to death in these forums.

My beef is with the after market companies who sell "upgrades" that are "stronger" or "better" or "faster" or whatever. So often they are not. too often they are just cr@p. Im looking at you eXtreme and KDBB and others!

I have broken the xtreme carbon frame in the first minor crash. Just snapped that carbon! i just broke the KDBB landing gear in the first minor crash. Both totally terrible designs. And other things such as the xtreme main gear and xtreme swash are average at best.

Note, this rant does not including the brushless upgrades or tail mods. for the most part these *moving part* upgrades do well. but the basic plastic part upgrade tend to suck.

I have come to the conclusion that for the most part, dont waste you money. buy the original parts and accept their short comings or mod them to your liking. they tend to last longer and be less disappointing than the after market cr@p that is peddled to us.

I agree 100%. Only thing the V2 mcpx needs is the eflite optional longer/solid tail boom (or make your own) and better batteries (I like 250 hyperions).

Tried all after market blades and imho the stock performance blades still perform best. The stock v2 tail blades work best as well imho.

I do have a microheli metal swash that looks great and seems to work fine but to be honest it flew just as well with the stock swash, lol!

Cheers,

Micro Heli metal is soft
One of my first helis was the msr. I bought tons of micro heli upgrades and none of them worked well. Everything metal is heavier and does not give in a crash.
I have a 3D heli, I don't understand why it doesn't do 3D.

+1, the "upgrades" can be a real can of worms. It doesn't take long to make a 200 dollar heli a 500 dollar heli Upgrading is Fun but sometimes your better off leaving well enough alone. I left everything stock except made the boom an inch longer-- very worth while mod. So then I wanted a smidge more power so put in C05 motor-- Loved it, but then I put in a more powerful motor-O.K Great but now the tail blows out
Put the C05 back in and I'm leaving it be, its good enough for me

Hey
It sucks to break upgrades you just installed.
And I agree the stock Mcpx with extended boom is great. I think a couple of other upgrades should be considered. The stock swash will get a lot of slack in it. My Microheli swash is much better than swash and the balls won't break like the stock swash.

Now this next one you will want to argue about. If you ever hit something hard like a tree,wall house etc you probably have a bent spindle. KBDD blades help prevent this in most cases. What you say there is no way! If you fold back stock blades against the blade grips they hit the grips sooner than KBDD blades due to the may they are designed at the root.

Don't believe me go check your spindle. There is any easy way to check if you don't know I can show you.

Now when you go brushless the upgrades become more important.

Love my Mcpx

Stock all the way, except for
The question is; Upgrades..... are they fixing issues or are they just BLING. and how do you tell the difference.

UPGRADES:
To me the biggest upgrade on the MCPx is the extended tail boom, but that is just a piece of CF rod, a cutting tool, and some sand paper.

That with some KBDD tail blades, and your good.

The metal swash also worked for me, as the plastic balls were breaking on my oem part.

Bling
Other than that, it is up to you. A flashy metal tail boom, paper thin CF landing gear, a soft metal anti rotation bracket, and the list goes on.

All I'm saying is that on upgrades, you have to figure it out. Making the distinction between upgrade and bling, is difficult in some cases and easy in others. (i.e. I've seen those CF landing gears. I have to ask did you really think that they would even stand up to a normal landing?)

I hope you have better luck making the distinction in the future.

I had a KBDD landing gear set fail by just pushing in a 550 mah battery. That was on an early production unit. The new one I fly with has worked fine.
I tried the oneway from extreme, garbage as the oneway didn't stay locked to the gear for long.
Tried the head from extreme, garbage as it rocks on the main shaft since there is no material in the center to support it.
I tried their grips which are okay, the links will not pop off which is a plus but you can't easily change them out either...
The extreme swash I tried sucked as the bearing had more slop than the stock unit!
I tried micro heli swash which is ok, just don't like the metal center ball as that wears poorly against the carbon shaft.
The rkh swash has been my favorite as it has a plastic center ball and works.
I tried the titanium feathering spindle from micro heli, soft as sh!t.
I would have to bend it back every minor crash, wondered how long I could get away with that before it would throw a blade. It was probably 50 cycles
Tried extreme main gears, they are garbage as well. They lose grip with the main shaft and slip. Even when glued...
What else did I waste money on?
KBDD blades, almost every set came warped. Now that you can get stock ones in bright colors I prefer them (bullets).

My experience with the mcpx overall has been a good one. The upgrades that work and actually improved performance for me are as follows:

Rakon Swashplate. The balls on this swash are snug on the links unlike other offerings.
CF extended boom ,stock tail motor.
Upgrade the wiring to the tail,,do not wrap the mag wire that is on the tail motor around the solid carbon boom. The insulation can easily be rendered useless and one short and smoke will result from the board!! CF does conduct electricity too remember. I use 26 gauge insulated wire.
V2 Tailblade
MH bladegrips. It has a wider surface area controlling the main blades so less gripping force is needed.I think the benifits of the blade grips is more apparent with a brushless setup. Never uses them on a stock bird.
Get a balancer of good quality or make your own and balance the mainblades. The smoother it is the better your gyro's will work.
This is basically what I found for the stock setup.
Setup is everything, All my heli's can fly far better than I can pilot them

Everytime a new machine appears these companies make anything that will sell. They aren't necessarily better performance wise but they are different. People like to be different. When I first got into the hobby, I was upgrade crazy. Now I look a little closer before I bother with higher end parts.Wolves don't lose sleep over the opinions of sheep

You got that right. What I don't understand is why these manufacturers do not test their stuff before releasing it to the masses. I hate being a beta tester.
Why release a head that wobbles or make gears that slip?
Why not address the issues and fix them and have a good aftermarket product?

Well alot of these chinese companies know when first produced that these products will be perceived as solutions yes?? The early bird gets the worm does not apply here. And if they do not work out they have your money anyway and for the low relative price ,,,you won't demand your money back. Too much hassle. BUT some of the products do improve the quality of the bird in question. It is a crap shoot ,,just like buying a new mcpx. Although you can holler at Horizon if there are problems. But then again you you pay top dollar for this possibility.
Forums like this are why forums are so important.
