This is my first stab at doing a scratch build quad project from all the hype that I have heard from my friends and the internet. Bought this HJ450 Spider frame, KK 5.5 ver 2.9 control board, G-Force 2212 motors and power distribution board from Value Hobby. Could not wait for G-Force 30 amp esc to get back in stock so I ordered Mystery 30 Simon K from another source. Put everything together as how it was described on the internet from YouTube and KK board manual instruction. Did not touch the control board at all and this thing was more stable than I had expected from a 5 - 8 mph wind conditions. I was amazed and will start putting on video components when this gets totally dialed in. I am very satisfied with the results and relative ease setting this up for the first time. Put 3 packs in the first day of flying and did not put a lot of money into this project. Thanks Value Hobby for putting in bang for the buck in the hobby. Great value for the money!!!
