Fixes: #11215

Thanks very much for this!

The incorrect use of centi-degrees was fixed in ArduPilot more than 18 months ago. Thanks!

@rmackay9: Can you confirm what version of ArduPilot this was fixed in?

@DonLakeFlyer: Are you happy with this fix as-is, or do you want to incorporate a version check so that it can use the legacy behaviour for old versions of ArduPilot?

[DonLakeFlyer]

Thanks for the change. It's going to need a version check for back-compat.

Hi @nexton-winjeel,

The ArduPilot fix was released with 4.3.0 which went out on 31-Oct-2022. Since then we've also release 4.4 and we're getting close to releasing 4.5. I still occasionally hear of users back on 4.2 and earlier but not often. Most users are on 4.4 while companies tend to lag a bit but even most of them are on 4.3 or 4.4.

That's pretty far back then. I think it's fine without a version check then.

Thanks so much!
