This motor is okay for a brushed MCPX setup. Mine lasted over 400 flights before drawing more current that I decided to replace it. It was still working, but I replaced it for fear of a crash about to happen. These motors will outlive a lot of the parts as long as you do not fly more than 3 batteries back to back.When hooked up to Nanotech 45C-90C 1S batts, this little thing is quite powerful for a brushed motor as long as you keep the weight down on your MCPX.Same as stock replacement with plenty of bite, just like the original. My only quam is it's a brushed motor, naturally I knew this before buying the mCP x so I can't lower the rating.bad material , broken to easy , bad material , change helicopter for other model , a t rex or otherA good brand gives us the guarantee of spare parts eflite blade that's thanks for having the parts I needed thanksspins the blades that continue to smash into things.The main motor is something that rarely breaks but I've managed to find a couple of ways. One was letting it get wet (by crashing in wet grass and not air drying it before putting it away). Another failure was due to over-heating when bearings and the main shaft got fried due to a micro crack. While neither of these are the fault of the motor, it is a reason for you to consider keeping a spare handy.It's easy to change out the motor. Remove the landing skid, the main gear and the 2 screws you can see by the pinion gear are what hold it in. It'll slide up without the need to remove the servos if you are careful.To compare this motor to a brushless one, there are a few differences. The first is cost, a brushless requires you to get an additional ESC to drive the motor and then buy a brushless motor too. The pro of a brushless motor is that it's more powerful and uses its own ESC so you have less tendency for the tail to wash out since the tail get all available power from the 3 in 1 now. I still keep one of my mCPX helis stock and it flies nicely. This is a great motor for the size and they did a good job designing the system around it.A brief mention of why you should consider try this mCPX heli: I really wanted to find a way to get my skills up to the level of inverted flight and some fun flying. The problem is that the cost of learning on a larger Heli is really high. To avoid the damage that a single crash costing $50 or more does to my pocketbook, I tried this micro collective pitch heli. I have been VERY pleased and have been able to conquer inverted flight and some tricks.The pros of this Heli are simple. It's low cost (relatively speaking for a Heli) and very crash resistant. When you do break something the pieces are low cost and easily available. There are a few cons with this Heli. #1, it's very small, and easy to lose orientation with distance, it takes good focus to learn how it looks at anything past 25'. #2, the tail is a bit weak relative to the main motor and you can get tail washout with full energy rotor actions. There are mods for this and the Heli is still very flyable in spite of this. Depending on your eyesight and budget it could be easier for you to move to a larger CP Heli, I have friends who love the130 for this very reason.The typical method of learning heli flying is to start with a coaxial heli which has 2 sets of counter rotating blades (Blade mCX2 ). That will help you learn orientation and the basic stick movement. Next, I went to a fixed pitch Heli to learn more control and stick management (Blade mSR). I stayed on fixed pitch too long and should have moved to this Collective Pitch Heli sooner since it wasn't that hard of a jump for me to make the change. I'll be sticking with this Heli until I have inverted flight and additional tricks down without damage. Next. I"ll move up in size since by avoiding crashes I'll be able to afford to fly the larger Helis. The great part about flying with this collective Pitch Heli is that I have it all programmed up on a DX7 with the very same controls and switches I'll be using on larger Helis, which helps me as I step up. Everything I'm learning and doing now carries forward.4 stars, it's a good solid motor but brushes is lighter and more powerful.
