Help! Syma X5 with Silverware E011 FC Misbehaving!


#1

Hello Everyone! This is my first post here but I’ve been lurking for some time but never found the need to create an account. Until now.
I have silverised a number of E011 FCs to use in 7mm whoops with great success (huge shoutout to NotFastEnuf, silverxxx and all others that helped develop this remarkable firmware), but when I tried to put another FC in a Syma X5 frame, it didn’t work out as well. I have begun PID tuning and messed about a bit with filters to eliminate the main oscillation, but quickly encountered an issue. Whenever I try to take off, the quad drifts uncontrollably to the right. I am in acro mode and this flight controller was taken from a working quad.
It can’t be a power issue, as enabling MOTORS_TO THROTTLE makes all the motors spin up synchronously, and I have ruled out COG and trim issues. I therefore deduce that it is most likely to be something in the firmware, though I don’t have the faintest idea what it could be. I would appreciate if someone could give me any pointers on where to look.
Here is the file I am using: LINK (nothing malicious, just shortened a Google Drive link with goo.gl. I have not changed anything from my usual E011 settings except filters and PIDs, iirc.
Thanks in advance,
Thomas

Drift is an accelerometer issue - you’re flying in acro so that can’t be it. Is it flipping out of control to one side or just slowly rotating? If slowly rotating - how hAve you eliminated the possibility of trim?

+1 for.NotFastEnuf, i was thinking that you created a new model in the transmitter with different servo centers.or subtrim or.trims…

Thanks for the quick reply. At centre stick it flips as soon as I throttle up. However, I can counter the rotation by applying a large amount of left roll. I have tried trim a bit but to no avail. I might explore that a bit more. @mcRich I will try creating a new model to see if that helps.

Can i ask which radio you use?

Flysky FS-i6 with an iRangeX IRX6 module for the whoops.

Hey @FelineFlyer,

have u tried setting up new model?

Sorry, been kind of busy over the weekend but finally got a chance to work on it. Created a new model and it now doesn’t drift to one side. Now for some serious tuning! Thanks everyone!
