ACC Needs constant calibration

[steve fh]

I noticed another comment re this issue i';m having

I can trim auto level via the sticks (Multiwii 2.1) on a flight and get a good functioning auto level. However next flight it';s forgotten the setting and needs trimming again.

Every time it';s the same. Flick on auto level and it wants to pitch back and right and needs a lot of trimming (IE disarm, full throttle and trim with pitch and roll inputs, light flash to show trim changes)

Has this been an issue for anyone else ?

If i hold the quad at about 20deg nose down and then do a ACC reset it';s just about level out of the box, but again forgets the setting next time out.

Just to clarify i have the machine well trimmed out on TX trims in acro and i';m not touching the TX trims when trying to sort level mode

Thoughts any one ??

Low temperatures can affect the acc and certainly affect the esc';s the rctimer esc';s are prone to this as they don';t have the external oscillator like some of the others do which can make them drift
