Futaba 3154 on 6 volts???
 

Hey Guys,
I am setting up my new Dragonus Elite and have acquired a Logictech 2100 gyro and Futaba 3154 servo in a trade, that I was going to use on the tail. I have read though that there are some problems with the 3154's on 6 volts in digital mode, so I am evaulating my options. This is my first "serious" setup of a heli, so I'm not SUPER literate on things, so any help would be appreciated. As I see it, I have several options. Should I..

1.) Just run it on 6 volts and hope it holds up

2.) Buy a step down regulator and run it at 4.8 volts? If so, what stepdown should I get? I've never read anything about them.

3.) Run it at 6 volts but in analog mode on the gyro

4.) Buy something like a Futaba 9650 or JR3400g.. any other suggestions?

I was hoping to get it flying this weekend for it's maiden, and would rather nto have to order something and wait for it to come in before I fly, but if it will keep me from wrecking as the result of a fried servo, I will. Could running at 6v volts but in analog mode be a "patch" for now until I either get a stepdown or other servo? As I said before... any input would be greatly appreciated!

Thanks Guys!,
Todd

from the little bit I found....

it is the gyro that is not rated for 6v...

the servo can handle 6v no problem

at least as far as i can see

RE: Futaba 3154 on 6 volts???
 

no.. actually the gyros are now rated for 6 volts.. the servos have a reputation for burning out very quickly on 6 volts.

RE: Futaba 3154 on 6 volts???
 

yes the 3154 WILL burn out on 6v. at least mine did. i dont like those servos at ALL. high priced junk. stick with hitec hs65hb's or mg's and you will be pleased.

RE: Futaba 3154 on 6 volts???
 

well since he's using it on the tail and not the swash 5v is fine and it's still faster than a 65hb. I think the issue is probably the fact that a tail servo is always working, adjusting to the conditions where a cyclic servo only moves with input. So running it at 6v when it's continously in use is probably what's killing them.

I think what I am goign to try and do is to HOPE my local hobby store had a stepdown regulator that I can use on the 3154 for now, and then order a 9650 or something along those lines. That way, if my local hobby store (that never has what I need) happens to have a stepdown, I can at least maiden my new Dragonus this weekend without having to worry about frying a tail servo.

i bought the 3154 brand new for 34 bucks. put it on the tail with the gy401. no regulators were used. used with the align 35a esc with the bec rating at 6v. not even 2 flights in the servo got hot then went completely dead. if you add the cost of the servo with a regulator its the same cost for a 9650 without the performance of it. but i guess if you had a small bird in the 300 size using this servo at 5v it would be ok. this servo is TINY!

The T-Rex 600 comes with a regulator for the tail servo that is light weight, inexpensive and works great for those digital servos that can't handle 6v.
