Hi,
My name is Steve, and i have been flying multirotors since Christmas after a hubsan x4 present.
I have now built a 450 class around a Naze32 with the baro and compass.
I recently got grounded when one of my hobbyking motors decided to eat a bearing, grounding me for a month while i bought a replacement set.
On testing for the first time in horizon mode, I had some strange throttle control issues. I would gain altitude and throttle back to level off and the quad would continue to gain altitude for about 1-2 seconds (felt longer), before responding to the cut in throttle. Fearing i was going to get a fly away, i decided to bring the quad closer and test at low altitude (6/8 feet).
While doing figure 8 turns, the quad did not respond to me setting pitch to the mid point (level flight), and responded almost as if I was flying in rate mode. After 1-2 sec control was regained.
As I had just flashed the FC to Cleanflight 1.9 from 1.8, I downgraded the firmware to 1.8 to try and go back to original setup.
I range tested to 200m (647ft) with no issues and full control, Walked the course with quad in hand (props off), so i'm happy this is not a radio issue as the problems are occurring in less than 1/2 this distance.
I have Failsafe on the FC and turning off radio TX the quad shuts down almost instantly.
Unfortunately i have the turnigy 9x with stock rom and 8ch receiver, so no failsafe on the TX.
recently I flew 2 batteries (4000mah 20c) and got 15-20min flight times (battery monitored to 3.3 per cell).
all was good up until almost the end of my second battery.
I was doing figure 8 turns and i was coming out of a turn and tuning in the opposite direction.
Needless to say the quad didn't come out of the bank and then snapped to the opposite lock matching my stick input.
the action was almost like the quad was stuck to something and suddenly broke free.
I was getting a bit of confidence up until this point.
Can anyone suggest any bench test I can do to diagnose where this issue is coming from.
I'd really hate to have a flayaway with something that weighs a kilo landing on their head!
TIA
Steve
