I put a 2n1 on my raptor and today I went out and flew it for the first time and the red light on the gyro wasn't flashing but like flickering and I never noticed this before but felt warm...I have the spektrum voltage reg inline so I'm sure it's not getting to much voltage..Everything worked properly though..btw it was 37 degrees outside

Is the volt reg and 2n1 wired correctly? I usually let heli temp stabilize 10-15 mins before flying when it's cold.

+1 on the 2in1. Also load test your battery.

I made a mistake once, but I was wrong?

Is it safe to have the 2in1 regulator and then another regulator inline with that?

Maybe it was so cold out the heat I felt was warmer then it really was....the heli been sitting in a unheated garage so the gyro didn't see a big difference in temp

If the red light on your GY401 is flickering then you haven't set your GY401 up correctly to begin with.

If the GY401 is in heading hold mode the red light should come on solid and stay on solid if you let the gyro initialize properly after applying power.

The red light will flash as you start moving the control stick or start moving the heli around (as long as the servo is moving). In general if it's just sitting still the red light should be on and NOT flashing.

The GY401 is quite happy up to 6.0 volts in, the output of the 2N1 is 5.8 volts.

If the servo you're using isn't happy with 5.8 volts, the you can put the step-down device between the 401 and the servo.

A couple of things to remember.

After the 401 completes its power up initialization in heading hold mode -- NEVER EVER USE RUDDER TRIM on your transmitter. The 401 learns where neutral is at power up. If you use your rudder trim after the 401 is initialized, you will confuse it, as it no longer knows where neutral should be.

Rudder trim in ALL transmitter flight modes must be identical. You cannot have different rudder neutral settings for different flight modes when running the 401 in HH mode

Always start the 401 in heading hold mode. The red light must be on, solid, after initialization. If it flashing, you didn't initialize in HH mode.

If I remember correctly the step down goes between the gyro and servo.

One of my Futaba gyros was flickering like that because the engine was running like doo doo. Any vibrations going on that you know about? How is the mounting tape?

Step down between gyro amd servo is correct, per my earlier response.

What servo do you use? You may not need the step down at all.

You will to step that voltage down for that servo

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

Has the gyro ever been in a crash that you know of?

The 9254 is good to 5.8v. The output of the 2N1 is 5.8v. Lose the step down, it is unnecessary.

It won't make your gyro behave any differently, but you will have one less component to worry about.

Is your tail rotor linkage and pitch arm free to move, or is it binding up due to dirt, oily goo, or some other cause.

Does the servo move freely and is it making any unusual noise?

If you switch over to normal mode, and move the control stick very slowly from end to end, does the servo move smoothly, or erratically?

How old is this entire setup?

I tried it today and everything performed good....light was solid....I thought the 9254 needed a step down...I'm using a 7.4 lipo going into the 2n1

It doesn't matter what goes into the 2N1 (well, it only wants to see a 2S LiPo on its input) as the 2N1 is a regulator whose output is 5.8 volts.

Since the 9254 is also good for up to 5.8 volts, you don't need that step down gadget.

I would prefer to use "the gadget" rather than running that servo at maximum allowed voltage.....the servo will most likely last longer at the lower voltages for which it was originally designed to run at.....that's my opinion and I'm sticking to it !!

Or you can simply replace that servo with a high voltage servo and not have to worry about it.....
