Is it possible to internally damage the KK2.1.5HC board without visible damage.
My thoughts are the FC board acts like it's damaged, but I have no expierence troubleshooting. I'm prepared to replace the FC board, motor and ESC, starting with the FC board.
Anyone care to share their thoughts on how to proceed with a timely repair?
I have ordered replacement FC and ESC, just waiting for them to arrive.
Thank for reading this rather long winded request for help.
Background info:
I have never flown R/C before, but the multi-rotors really look like fun to fly, so I'm trying to learn all things at once. I turn 60 this month, and want something to tinker with.
The learning curve is steep but doable.
I assembled this quadcopter early December 2015, and bought the HK Q-Bot micro quadcopter at the same time to allow indoor practice over the winter.
Thankfully the Q-Bot Micro is durable and not to hard to repair! I have tested it's crash worthiness, and improved my repair skills in the process.
My quad build is:
Hobby King F330 frame
Turnigy D2822/17 1100KV motors
Hobby King Blue series 20a ESCs
Hobby King KK2.1.5HC flight controller
Turnigy 9x TX and RX
The KK2.1.5HC board is mounted inside the the frame.
I removed the bullet connectors from the motors and soldered the connections.
I have only flown, and crashed the F330 twice, and learned from both experiences. The first crash was flying to close to small shrubs and I broke a propeller. The second was I lost orientation and ditched it before I damaged some property.
The last crash broke a frame arm and ripped one of the motor wires from the ESC.
I replaced the broken frame arm and re-soldered the motor wire. Everything seemed to work.
My last attempt to fly was frustrating.
When trying to lift off, the quad flipped over hard. It acted like the left rear motor wasn't spinning-up fully. I held the the quad and raise the throttle to see motor function. The left rear motor seem to speed up and slow down out of sequence. When I tipped the left rear arm down it didn't respond very well.
I plugged in the KK2.1.5HC board remote screen and saw a calibration error, so I re-calibrated the board.
I could take off in "auto level" mode but not without it. I could just get it off the ground and the quad had a low speed oscillation that it didn't have during the last flight.
Once in the air about a foot, if I applied more throttle it would flip violently. If I turned "auto level" off it would only flip over. The right front motor would go to full throttle and the left rear motor just barely throttle up.
Thanks again!
