Hi GB,
Great video and nice indoor flying shop...what exactly kind of shop is that?
One thing on the mcpx...the flybarless unit does not compensate for piro's, so you have to make the corrections yourself when transitioning from tail to side to nose to other side.
Congrats on taking apart the servo's and cleaning them. Really makes a big difference. Many use DeOxit but any cleaner/lubricant will do the job. I usually use a shammy towel to do any work on it as the screws don't fall to far when they fall on the shammy, keeps everything in one place.
Keep up the progress!
Mark
