Guys, I need to find out what voltage the GV1 sensor can handle. I just added a LiFe rx pack at 6.6v and have a western robotics tail regulator which will drop the voltage by .8v for the sensor.
FBL unit is Skookum 540. Manual suggests that most sensors will be damaged by voltage greater than 5.5.
Anyone here used a GV1 sensor above 5.5v?
What do you suggest?

The GV1 is rated for 3.8-6V. I would think that the sensor would be rated the same. But, to be sure check the output voltage on the sensor port.

Ive been using Life packs unregulated with the GV1 on my Turbulence and an Evo 90 for a few seasons with no problems.

The red and black wires should be on the same bus as everything else in the govenor, just like a receiver, so the sensor should be able to handle whatever voltage the govenor is using. I used to run unregulated 5 cell nicad packs back in the day with the GV1 with no issues. A fully charged pack would be almost 7 volts.

Thanks for the feedback. I checked the sensor port on the gv1 and it outputs around 5v or just below. Interestingly enough the servo port was at a different voltage than the sensor port. It was either higher or lower depending on what voltage input I gave it. It seems the gv1 is regulating the sensor voltage to be around 5v.
BTW, I did use a step down to the gv1 from my 6.6v source for testing.
Since I'm using the skookum for the governor, I added a diode to my wr regulator. The voltage with no load is now around 5.27v.
I will test fly and see if it works...

The Skookum has a pull down menu for checking the sensor operation - both the voltage & the trigger.

Yes I see the trigger. Looks like it's working.

Test flew okay except for the hole in the piston. Lol. It's been a while since I tuned a nitro. I guess ill be rebuilding the hyper....
