Bruce – Adelaide Sth Australia:- Hi everyone thought I would share my experiences in the hope it migh help someone else:-
First time I flew my hex I lost control and it ended up in trees, broke an arm and prop.
I did not know why at the time, it was set on GPS Altitude hold, but it just did it own thing.
I know now it was suffering from extreme TBE.
I know to you experienced guys this is nothing new, been there done that, but for someone new its perplexing.
I read so much about how stable Naza was even in wind and how GPS/atidude hold mode was so good.
All my settings were as per manual with GPS sensor facing forward 0 degrees.
I did more reading in the forums and it seems even now there is still divided opinion about how to cure TBE.
I had to start somewhere, I knew all my configurations Radio and Naza assistant were correct.
I offset the GPS sensor by the Adelaide declination of 8 degreesEast, rotating sensor CLOCKWISE – this really had NO Effect at all.
Then 16 degrees, this was better, it would not initiate the TBE but when purposleyput into one it took 3/4 to 1 minute to sort itself out and stop (still doingquite a few rotations). Well at least I was on the right track and it isimproving.
Finally I set the GPS sensor to 30 degrees clockwise from the forward axis ofthe hex and all is cured, even if trying to manually initiate the TBE as soonas controls are released the hex stops. SUCCESS.
I question the logic 8 degrees East of actual magneticdeclination and the sensor having to be set to 30 degrees to totally neutralisethe effect, this does not make sense to me.
Anyway I'm glad its sorted and the hex is behaving as it should.
Thank for reading this and I hope it helps some who might have the same problem.
Regards - bruce
