Shipping was very fast, took around 10 days and all was good to go. I was planning on changing my Cruis AIOP ver2.0, seeing as i have never been able to PID tune it properly. Mounting the FC was simple. The hardest bit about it was converting the mounting holes, the Crius is much wider 50mm x 50mm compared to 35x35mm for the CC3D. I saw a very cheap mounting plate at under 2 dollars, it fits the 50x50mm on the bottom plate, has vibration pads, the top plate is smaller and fits the 35x35mm of the CC3D, The Talon frame which i was mounting it on has only mounting holes for a 50x50mm mount, but seeing as i intitially thought that the CC3D was just for testing fun I refrained from purchasing more accessories. I ended up building a wooden mount and after that was done, the board was mounted and ready in under 10 minutes.
My flying skills have picked up some what after using the selflevel of the KK2, so thinking that i was in selflevel/Stabilize mode, I lifted off, what i did not know was that i actually had reveresed my channel five and was flying in rate/manual/acro mode and wow it was almost tuned in, Prior to this i had never flown in rate/manual/acro mode before, but with this board it was a breeze, very responsive and was just cool to fly. So if you have been stuck the KK2 for a while, this board could take you to the next level, the KK2 was fun to fly, but now it is soon time for real action. You can of coarse buy this board from some official sites, and i would suggest that you buy it from hobbyking or another certified retailer.
Open Pilot have stopped manufactering and selling the cc3d board, so you will mainly just find clones on the net, these clones are of varying quality. Mine died after a couple of days and greenshop333 was very quick to offer a refund, so would not hesitate to use him again for the same board and hopefully the next will be of better quality.
3dr telemetry to the board through the main port, so no need for an USB cable. The cable is supplied with the CC3D .
read the online manual to get the corret ports. The software will confirm if you got it all right and reversing of the channels is also done through the software. The software is very illustrative and easy to use.
