Every one of us that own the mcpx have wanted to do this upgrade. I mean lets face it, brushless is the way it should have come from the factory. But that is not how it comes because they want to save money. So it's up to us to do it ourselves.
Unfortunately, the company that I purchased this kit from ripped me off. It came from Wow Hobbies in California. DO NOT PURCHASE THIS KIT FROM THEM! Even though they say they have one thing on the site, they will sell you something else if it's cheaper for them. They could care less about the customer, they only care about their bottom line.
With that said, all of the items are from other companies other than where I purchased the "kit". This is a true plug and play kit. If you want to purchase a kit like this, come over to the forum and I will point you in the right direction.
Have a watch at the video and let me know what you think. Maiden flight video soon!
