It's my pleasure. The YEP as I stated is supposed to be a great ESC. The Corona servos I have no time with so don't know anything about them, but do have them on order. so I will know for sure soon. But, I have used the EXI D213F servos and they are great. Digital and metal gear. The Solar D650's are pretty good and they are what I'm running on my HK450GT right now. I"m having an issue once in a while with the elevator servo, but I think the bolts that tighten it to the frame are too tight causing it to lock up. But, I have not had a failure iwth it yet, and I have flown them about 5 times so far. More once my parts come in on Thursday.
I would highly suggest that if you are flying CCPM already, move up to something that is a bit better. Obviously Align is what I'm going to suggest, but if you follow the video that I will be making in the next few weeks, you can get a clone, then just put Align parts on it. I will be doing a full series on building a clone the correct way.
