Hi,

I am setting up a raptor 50 titan se.

Gy520 with BLS 254

Cyclic: BLS 451

Futaba 9254 on throttle.

Receiver: RD721 JR

Radio: DX 18QQ

I have few questions:

1.In which channels do the red and green leads go in THIS particular receiver?

2. It is a dual output regulator. Right? So, cyclics can run at 6 volts and rudder at 5 volts. How do i do that so the cyclics (BLS451) get 6 volts independent of rudder.

3. Can i connect a step down in between the rudder servo and its connection to the gyro.

At the moment fromeco is set at 5 volts. I have again connected a step down in between the receiver and Throttle s9254.

Futaba says 4.8 volts for BLS 254. Is 5.0 volts tolerable or i shall reduce it to 4.8 exact?

Doc

Hi,

I have seen this.

I am getting confused bcoz two leads from gy520 are coming out and getting plugged into the receiver gear or gain channel (red colour) and rudder channel (Black).

So, can i put the two leads from fromeco into battery bind port and Aux 2.

"The Arizona Regulator has 2three-pin connectors, for pluggingthe gyro leads intothe regulator.
One is labeled “GYRO GAIN”, andthe other is labeled “GYRO RDDR”. When viewingthe regulator
from thetop, and withthe wires pointingtoward you, ensurethat the gyro plugs are oriented sothatthe
wires are “NEGATIVE”, “POSITIVE”, and “SIGNAL”, as viewed f rom left to right"

Things are much clear now. Will go home and connect the two leads from gyro into the fromeco and fromeco leads into appropriate channels into receiver.

Yes! That's the image I was looking for, but couldn't find it last night.

The Arizona puts out two voltages. One is a fixed 5V for the gyro/tail servo so you don't need the step down on the tail rotor servo.

Step down for s9254 on throttle
Hi,

I have got the connection right on the Fromeco regulator.

Thanks for helping me out.

I have Futaba s9254 as throttle servo. If i increase the voltage on fromeco to 6 volts. The cyclics and throttle will get 6 volts.

Is a step down regulator between throttle servo n receiver ok? Is 5.2 volts ok for 9254?

5.2v should be fine for the 9254. Futaba does not recommend (from specs sheet) 6v for the 9254. I don't see why you couldn't use a step down for the throttle servo.

Simple diode step down will be fine for the 9254 on throttle. That would have it see about 5.7V which, when used on that servo for throttle, will not cook anything. Been there, done that.....

I have a very similar setup on my 600N I used the gyro lead (its fixed at 5V and I set the Regulator to 5.5 (I think you can jump it for 5 5.5 and 6 volts)

.5 is the nominal voltage on my 2 cell lithpoly in a fully charged state. Your servos wont weaken or choke on 5.5 (shouldn't) The 520 the same 5.5 wont hurt a thing. (I had the 520 on this setup initially) I decided that the difference between 5.5 and 6 was not enough to worry about performance loss. (I have 8717s on my cyclics and they are plenty fast at 5 volts
