Gaui governor not working

[ihamsa]

I have finally finished my NX4 build, it works OK, except the governor.

I have the mini V-Bar and Spektrum satellites. The set-up of the V-Bar was modified to allow usage of satellites as per this article.

The governor sensor works, as the LED blinks when the blades rotate. The gain channel works, the light changes from red to green when I fiddle with the value. The throttle channel is calibrated according to the manual --- press the button, move stick up, wait 3 sec, the light changes to green. But the RPMs just won't stay put.

Any ideas?

I just changed out my mini Vbar to an Ikon2 because I was never happy with the way the Gaui gov did/didn't work with the mini V. Followed all the instructions and modified the register file. Did the throttle calibration got the green lite, put in the recommended v-curves, enabled the gov menu in my transmitter. Seemed like it worked but never really sure. What put me over the top was how the mini v didn't like vibes. As soon as I'd crank up the headspeed the heli would roll very slightly to the left. I used the metal plate and all the proper pads too. I love vbar's so it was hard to change but as others have said the mini v isn't really designed for nitro.

Figured I'd try an Ikon/Brain2 because the one on my Protos is working really well and it was alot cheaper than the vbar. Long story short, the Ikon works great on the nx4. If possible consider this change.

Thank you, I'm considering the Ikon2 but I want to try and make the current set up work first, I feel I haven't exhausted all the options.

How do you know it worked? Did you measure RPMs with a tachometer? Did the gov kick in at 1/3 of the stick?

Which Ikon model do you heve? Are you using the built in gov?

I measured my headspeeds with a handheld tach. I'd do the flying while a friend did the measuring. It seemed like the heli was flying with the v-curve and not the governor % value that I set in the gov menu in the transmitter. I could change the value but the headspeed would not vary. I could change the v-curve and the speed would change. If this was how the Gaui gov was supposed to work then I totally missed that. On all of my other governed helis I would change the gov % value in my tx and the headspeed would change correspondingly. The heli flew well with the vbar but like I said in my previous post, when I turned up the headspeed (think it was around 2700) the heli would start tipping to the left. Below that rpm there were no issues. What radio are you using?

I'm using the standard Ikon2. Would have liked to use the HD but its quite a bit taller than the regular unit and it looked like it wouldn't fit under the canopy. As it is I have a slight rub mark on one of the front corners of the Ikon after a few flights. The Gaui sensor will plug into the governor slot but you will have to get an adapter or cut off the small jst connector and reinstall a regular servo plug. Make sure to switch the red and black wires from the Gaui sensor when you do this. Red wire from the gaui sensor is on the outside when on the servo plug it is in the middle between the black and white wires. The Ikon gov is working well.

It looks like your gov didn't work for you either. Thank you. Maybe I will try an Align gov before giving up on mini v.

Yep, no sense in giving up on a great fbl until you try all the options.
