This brush-less speed controller and motor works well. It comes form fitted to the model it is listed for. (F45/645) It has the brackets to allow the motor to fit in the small space-with minimal clearance. The speed controller fits into the space below the receiver board with holes formed for the mounts to slide through. If you have an older battery, you should get a voltage alarm. I would STRONGLY suggest this. Without one, the bird can just shut down at the end of the battery cycle. (happened to me) I would recommend this for others with the condition they address the concerns I listed.

Got my kit earlier than promised. No instruction included but I was able to find a Chinese seller's site which has step by step instructions (in Chinese though) and got the motor swapped within an hour. Took the heli out for a spin. Wow! What a difference. It actually flying in a 5 to 7 miles wind at my command. I was flying it in my cue-de-sac so I was powering it no more than 60%.
I'm glad I spent the time and money to do this great upgrade.

Update 08-27-2013:
Took it to the park and flown continuously for 10 minutes with the stock battery (1500mAH). The new brushless motor was barely warm while the stock tail motor was hot to the touch. Time to get a tail motor heat sink.

I installed the brushless motor upgrade kit to my MJX F645 and it works great. It is quieter and has more power than the original motor. If you are looking to upgrade your helicopter this is the way to go. It is a little work to install the kit but well worth the time.

its a great kit everything you need is included. quick shipment as well considering. only down side is: no instructions and the included screwdriver is bobo.. just a quick file to the tip and its good to go.. with this upgrade the mjx gets super fast and agile.. I must recommend the bigger battery as well
