Hey guys I finished setting up my microbeast plus and I was sure to do the proper steps for my tail servo endpoints as well as the right pulse lengths and frequency for my torq 9188 tail. My question is on the bench I really don't have much for throw left or right and I know how to change HH and rate modes on the original MB by changing the colors but I can not find how to switch on the plus. I've tripled checked the frequency and pulse length and end points and I get ALOT of throw when it's in set up mode but as soon as I finish I get like a quarter of an inch total (if that).
So does anybody know how to switch between HH and rate mode on the plus??? Thanks guys

Not familiar with the MB in particular but on the gyros that I'm familiar with the gyro gain wire is connected to a channel operated by a switch such as channel 5 on a standard JR/Spektrum receiver (typically gear switch). Toggling the switch from one side to the other controls the HH vs non HH function.....

Been there, done that and old enough to know better.....

I do not have a Beast and I've never owned one.
However, I've had a lot of gyros - both tailrotor only and FBL.

Usually, (and, maybe it is different for the uBeast gyros) switching between Heading Hold and Rate is done using the transmitter's tailrotor gain channel.
I.E:
TR Gain in the TX is -100 to 0 and the gyro will be in Rate mode.
TR Gain in the TX is 0 to +100 and the gyro will be in Heading Hold mode.

Also, when the gyro is in HH, the amount of compensation is related to the TR gain, and not so much the position of the stick.

If you have a high TR gain value, rotate the nose of the heli left and right at least 90-degree and see if the blades on the TR travel to the extremes to compensate for the direction you are rotating the nose.
I.E: If you rotate the nose left, expect the tailrotor blades to compensate in the direction that will force the nose back to the right

In setup mode, you are basically setting the servo's positions for center, maximum left and maximum right travel.
But, I doubt you will be able to get maximum travel from the stick on the bench unless the gain is really high and you are moving the nose.

Believe 1/2 of what you see and none of what you hear.
Fake News will be the downfall of our Republic!

- Go to your TX and adjust the Tail Gain higher
- The higher the value, the more pitch slider will move

Just in case
Torq 9188 tail
- Tail Center Pulse is 760u - Red LED
- Tail Frequency is 333z - Flashing Blue LED

Yup that worked flawlessly guys. I appreciate the info.
I set up the gain on my VR knob so I can adjust in real time spooling it up in my basement. She's got the shakes pretty bad when I start it up so I'm attributing that to the -12 degrees that it sees before I hit mid stick. Next step is to figure out how to lower my pitch range in normal mode and save the -12 and +12 for my idle ups.
What do you guys typically run on normal mode like a -3 and positive 10 maybe . But obviously mid stick would still be 0 so when I go into idle up I won't have a huge jump in pitch range?

I run the same pitch in all modes just for simplicity. If I wanted less negative in normal like your self I would just increase the 0 point in my normal mode pitch curve, so instead of being 0-50-100 it would be maybe 25-50-100.

The other reason I don't do this is when landing in normal mode (which I rarely do admittedly, and just do a mini auto.), it makes anything below mid stick inconsistent with IU which is where im used to flying most of the time.

Spool up is no problem as you have plenty of time to get to around mid stick before the blades are upto speed and IMO you should always land using TH, or at least touch down and then hit TH.

60% of the time, it works every time!
