Spirit System

I have a OS 105hz that is Practical rpm: 2,000-16,500, it's on a Goblin black nitro 700 with gear ratio 8.23, so max HS is 16,500/8.23= 2005HS, I'm at 85% on linear Throttle on GOV mode and I'm getting a reading on my Jeti of 2500 that is imposible, I use a Back plate, I sir of tachit and it was ~1700 that's sound correct!!
What can it be or how do I fix this??

Hello,

if the reading is stable, then it could be just Gear Ratio settings or Sensor Divider.
For Backplate sensor it should be configured to 1.

If there is only small load, the RPM can go very high. Do you use optical RPM meter?

All setup is correct, reading were constant, but was on a hover no really load so maybe that's way.
Will check tomorrow on the field.

Of topic if I want to tame the heli so I use expo naw they are at 25% or were do I do that, since I'm letting a friend fly my heli.

Great.

You can set Expo in your transmitter as much as you want for any channel.

Yes, these numbers are absolutely fine and in good range.
