Hello Guys,
i built a quad, based on the Tank Quad. Basically the HL Frame from flyduino.net with 25cm CF arms. I used kiss escs and T-Motor MN3110 700kv with T-Motor CF-Propellers (rudimentary balanced ).
The AQ6 stands on stiff nylon standoffs and the escs are placed in the prop wash.
The whole system is driven by 2 4s 3300 mah lipos which give a AUW of 1900g. (hovering at 50% throttle)
My radio is a FrsKy Taranis with a homebuilt S-Bus converter.
This combination flies very well in my opinion, without a connected gps antenna. As soon as i connect a gps antenna and it has a 3d fix, it completly goes crazy. All operations are done under the normal manual flight mode.
I did a tare and a onboard magnetic calibration. (I think the result is within the tolerance)
The attached log contains data of 3 flights. First flight was done with connected gps but prior 3d fix, the 2nd and 3rd were cancelled takeoff tries, because of an unflyable state.
If the Problem occurs, the motors sound different (higher frequency of speed changes) but uncontrolled and without system. The quad seems to flip the next secound. To prevent this i land immediately but its in a highly unstable state then.
If there is no gps fix i can fly very stable even in very windy conditions (manual height control). I have to admit that my garden is probably the worst testing ground, because there are high trees which are causing immense turbulences.^^
Perhaps u can have a look at my logfile and point me into the right direction.
Thanks in advance
Johannes
