I decided to build a 500mm quad using the Turnigy HAL frame so I ordered everything and put it together. This is a NAZA M LITE systems with Skywalker 20A escs, 1100kv emax motors, 10 x 4.5 props,2200mah 3s 20c battery and a flysky 6ch transmitter.
It flew perfectly for a few minutes and then suddenly it was out of control and crashed into the ground. Luckily nothing was broken so I check it over looking closely at solder joints ( I did not use an plugs), checking connections. I recalibrated the escs ( all four at once), re calibrated the IMU, recalibrated the GPS, recalibrated the transmitter, I did it all. I also rechecked the esc settings and made sure the right props were on the right motor and that the motors were spinning correctly and I went for another trial run, this time in ATTI mode, no GPS and again it flew great for a few seconds and then suddenly was out of control before slamming hard into the ground. This time the crash warped the new frame and destroyed the landing gear.
Any ideas what could be wrong? I know that others have used the Skywalker esc's with the Naza Lite. That's why I chose them. They are not flashed or anything must stock Skywalker 20A escs. One thing that I noticed is at startup two of the motors would not spin until I gave it throttle. Then all would spin and the quad would lift off the ground and was very stable for at least a few seconds.
If you have any ideas or suggestions please let me know. I appreciate any help at all.
