401 Gyro at 6V bad idea? or ok.

[JayB]

I just got an align 35A speed controller and was about to throw it into my mini titan. Checked all the servos to be sure they're compatable with 6Volts and they are. But I went on towers site to check if the gyro would be ok with 6V and their site says this. "
GY401 Gyro-
Length: 27mm
Width: 27mm
Height: 20mm
Weight: 27g
Voltage- use only with a 4.8V battery. (if you use it with a
higher voltage battery it needs to be regulated to 6.0V)

Does this mean it's ok to use at 6.0V or should I stick with the 4.8?.... Hummm....

[whiteknuckleairlines]

I had always been under the impression that the 401 could take the higher voltage, but it was the tail servo that needed to be on a lower voltage because the fast futaba servos will roast on anything more than 4.8...

Where is Nitro? he will know..

The Futaba gyros do not like 6 V, that is why Fromco came up with the Arizona regulator. That provides 6V for your flight servos and 4.8V for your gyro and t/r servo.
That is the only drawback of the 401, otherwise it is a great sport gyro. I have one on my Jetcopter and it works super.

According to the servo specs my tail servo can handle the voltage (Futaba S9650). But I dont really want to mess with the gyro.

So I got an idea. Can I just throw a regular fromeco regulator on it. I really only want the speec controller for the soft start function.

[whiteknuckleairlines]

So how would you handle that in the case of a phoenix 35 dst? Does it output at 4.8 or 6 volts? I just revisited my manual and didnt see anything about its output voltage..

[JayB]

I have an electrifly 40A esc right now. Just checked the voltage at 0Amps is 5.1Volts. then checked the align. 6.0Volts on the dot.

Hmm.. im going to have to check my phoneix when I get home...

[RappyMan]

It sounds like 6V actual is fine. You just don't want to use a 5 cell RX pack as input power - it can be mid 7V or better on a fresh pack. On my Raptor 50 I have a 5 cell pack, but have it regulated to 5.6V (all I could get... or I would have went 6V)

[JayB]

I'm gona fully charge my lipo and then plug her in and if it's at a solid 6.0V, no more. then I think I might give it a spin.

It is right there in the specs you posted.

The 6.0V out of the align or any other ESC or BEC is regulated.
As was mentioned above the only place there is a problem is with running a 5 cell pack direct. It is the 9253/4 servos that do not like 6.0V, regulated or not.

I have been running a 401 on regulated 6v for 2 years and hundreds of flights with no problems.

[JayB]

Just sat in my chair and hovered in front of the computer for about 6 minutes with the new align esc on 6V. No problems. Thanks for the help.

I flew with the 401 and 9650 at 6v for over a year...no problem

Holy crap Curtis!!! That's one he!! of a battery pack you have!!!

[exeter_acres]

Yep... LOTS of mAh!!!

Took a while to charge...and it was heavy, so I just left it on the ground and used an extension cord to the heli... had to be careful on flips, but it worked out OK..







(it took me a minute to figure out what you were talking about, but it is pre-coffee!...
Oh and Boulder... new snow up here!)

LOL!!

Oh, by the way, really sorry to hear about the snow

Let's see, today it will be in the low 80's with a light southwest breeze
