There is an exception in the latest 3.7.0 firmware

[shi555]

I updated the spirit RS software to 3.7 and the firmware to 3.7 and found that the No. 3 servo was not working properly. It was unresponsive, jumping and stuck (the same was true in the BEC test). I swapped the servos and found that the No. 3 servo port was the problem. It was not normal, so I returned the 3.6.2 firmware and it worked smoothly and normally.
（The work of the No. 3 servo is similar to that of the three-position switch.）

Hello,

please update to 3.7.0-r2 from today. We are very sorry for the troubles. The bug appeared itself (made by compliler tool) but we made sure it can't happen again now. It could affect only some Spirit Pro, 2, RS units. Now it should be all OK.

If everything moves smoothly on the ground it is.safe to.fly?
Our should i downgrade to 3.6.2 again?

Regards
Philip

Yes, it is safe to fly.

I did several flights today on different helis and Spirit units. (RS, GTR and old normal spirit) with the 3.7rc2.
Everything worked fine!
Love the finetuning possibility of the rotation rates !
