I bought one of these cheapo X-Dart quads from HobbyKing($19) and didn't realize it was a Mode 1 (throttle on the right). Since I have no intention of learning Mode 1, I decided to tear the transmitter apart. The Mode 2(throttle on the left) hack was actually fairly easy. This does require some...

Hello, Quick question. My RX on my quad lost the AILE channel. I tested it with a servo to make sure,and it has a bad connection on the board. I tried to re-solder the pin, but I think it is a crack or something on the board. Anyway, I ordered a new RX. When I hook up the new RX, can i just bind...

Hello, I have one of those el'cheapo gopro gimbals from goodluck buy, with a martinez board. I have spent numerous hours tuning, balancing etc. I have balanced props, and an extremely stable F550/DJI Naza setup. I am having a very annoying slight jitter problem when I fly. One thing to mention...

I have a minimOSD and Leah-6H. I want to create a system with a dedicated GPS antenna for my OSD. Any suggestions or tutorials on this? I basically just want GPS coordinates and voltage displayed.

I bought one of those cheapo HK osd's($24) It came with an old GPS antenna marked 7/27/2004... I got it to lock one time, and the coordinates were 10 miles away! Has anyone had any success using a better GPS on one of these? I tried a LEA-6H and I didn't have any success. Im wondering if the...

I am just about done my F550 build. I have all the Failsafe functions, and switches working properly(according to the assistant program) I have seen some posts about programming the throttle 10-15% when it goes into Failsafe. Is this necessary? Any input would be appreciated.

Has anyone successfully been able to have the Naza programmed into failsafe with a Spektrum DX-7? I have the 3 position switch calibrated for manual, attitude and GPS. I tried setting a trim to Failsafe, and then rebinding the receiver. If I turn the transmitter off when it is plugged into the...

Just a word of caution for those getting into this hobby. Most of the challenges I have faced are because of improperly placed wires in wiring harnesses. Most of these products were from E-bay or discount Chinese Hobby stores like Hobby King. My first issue was a Video Tx/Rx from Hobby King...

I got the dreaded "Bad Gyro Health" message with my Hobby Works HK v2.5. My first mistake was buying the HobbyKing board. These things are junk. Terrible solder joints, bad lamination....junk. I should have spent the extra couple of bucks and got the board from 3DR. I haven't even flown the...

I am upgrading my KK2.0 board to an APM(HK 2.5) board. I bought one of those inline 5v power modules, but the 6 pin connector is slightly different. Does anyone know where I can get the correct 6 pin cable with connector? I may have to splice, but that is ok.

After hours of tuning this week, I had my DJI F550 flying really great. Unfortunately, my old DX7 transmitter battery gave up in mid flight. I knew the battery was getting weak, and would leave it plugged in between flights. 100% my fault. I smashed the rig pretty hard, and broke one arm into 3...

I just built my first Hex, DJIf550 frame. I used cheap basic stuff, 930kv Mystery motors, 30A Plush ESC, 11.1 30c, 10X4.5 props, and kk2 board. I am using a DX7 and ar6100 micro reciever. I could not get this thing to fly until I turned the Pgain settings all the way down to 20 (Igain settings...
