T500 tail drift

Thomas, no the belt is tight but not to tight, what if I put 2 sticky pads under the gyro, might that work?

Just to confirm, the delay on the gyro should be at zero with the 9257 right?

I have fixed the drift on my 401 and others simply by resetting the gyro. To do that switch the heli on in Heading hold mode (solid red light on gyro). Then put it in rate mode and flick the switch quickly between HH and rate 4 times to end in HH mode.

I can almost guarantee that will cure your problems.

Yes and the DS switch should be set to "on"

Sieze2,
That did the trick, but about a minute later I had a mega smash (my fault), blades, main gear, both shafts, tail and boom, and stripped the 9257 gears!!!! (can you get gears for the 9257). Anyway, thanks for sorting my drift problem.

I had the same slow drift the other day on my 500. I always flick the switch several times before flight anyway after I've carried out to the take off point. Un-plugging and re-booting the gyro didn't fix it . Next day the drift was gone!

Only other time I've had this was on my 450 on a cold winters day when it'd just come out of a warm car. Left it a while to acclimatize and all was well.

Got no idea why the 500 had this problem??

Bollocks, who told you that crap? I always flown JR and used 401s as have many others and never heard of a 'common drift' problem.

Actually it's NOT bollocks. Why would I make that up?

And it's not just a one-off situation.
Many people running 401's have encountered drift with JR radios.

After exhausting many other options, the slight sub-trim change was the fix.

The purpose of the subtrim is to move the centre reference point slightly. Maybe it's a voltage clash JR vs. Futaba. Who knows!

Do some more research pal before implying that I'm speaking rubbish.

Its one of the simplest fixes you can do on a RC heli ! It always works ! Sorry to hear about the crash - it happens
