I am looking for Digital replacement servo's for my D03.

The opening for the Servo's are very small.

Does anyone have a part number of Digital Servo's that will fit the opening on the D03?

Thanks For your help,

Dennis

Break out the calipers to double check size

I have been reading threads from all over the Globe.

It appears Walkera built this bird so NO other electronics would work with it.

After reading about 10 threads, I have decided to ditch the project as if all these other people couldn't figure it out and get other servo's or ESC, etc., to work, well, I wasn't going to keep trying.

Next step will be a 500, 550, or a 600, strictly a bird to practice with, and trying new equipment.

I have my 700's and Scales, so I am happy.

Yes, but... did you measure the servo?

Go 550 as it uses a 6S and can stretch to 600 if desired.

Pistol Pete, Yes, I did measure the servo's.

I appears what I want to do is not going to happen on the Walkera. Many have tried, and I have not found one who succeeded.

So i am back to the drawing board.

If I found someone who could add a Gyro to the system with no issues, I would ship the Heli to them!

Thanks Again, and take care, Dennis

Pistol Pete,

That looks like the stock ESC and the Gyro?

Now if I could find a Gyro like a Skookum or 3SX that would work with the rest of the equipment, I would be in good shape.

I put a Skookum 720 on a Stock 450D03 and I burned up 3 servo's, all were stock.

I am just looking for a practice HEli, I wasn't going to leave the Skookum on the Walkera.

From your YouTube Video, it looks like all I should have to do is add the Skookum.

What's your thoughts?

Dennis

Troubleshooting...

Frying the servos is either from over voltage and or PWM settings.

No clue if original servos in your D03 are digital or analog.

Very few FBL have a setting for analog servos, so digital servos are a must. You need to verify if Skookum has such setting. Given servos are already fried, checking just validates what could have caused failure.

It is unlikely that the servos that came with heli have a special requirement other than 4.8V min to 6V max (the norm) which applies to both digital and analog.

Servo voltages out of the "norm" are the ones rated "high voltage" that can handle a 2S lipo, thus no BEC needed. Definitely not in your heli but mentioned for the halibut.

IF servos were digital and PWM was set correctly, then the problem was over voltage.

The positive-negative pins to both FBL and Rx are in a bus configuration. So all channels will have same voltage OUT as the voltage IN to power the unit. (V-In = V-OUT)

I will assume voltage IN for Skookum was from ESC which "hopefully" has a built in BEC (voltage step down) and set to 5V.

ANY "separate" FBL, Rx, Sx and ESC units can be used in "ANY" heli unless heli has a unique proprietary system "all in one" combo board, such as the 180 size helis.

By "any" I mean sized to heli accordingly.

Rx = receiver
Sx = servo

Hope this helps you achieve your goal.

Pistol Pete, First, Thanks for the reply. I will answer in Red lettering within the body of your response below.

No clue if original servos in your D03 are digital or analog. They are digital, and very had to find info on them.

Very few FBL have a setting for analog servos, so digital servos are a must. You need to verify if Skookum has such setting. Skookum has setting for both digital and analog.

Given servos are already fried, checking just validates what could have caused failure. I have good Servo's for the Walkera.

Yes, it helps. I would love to set up this Skookum on the Walkera, but my main issue seems to be vibration. The Skookum is very sensitive to vibration. I am thinking about going to a larger Heli just because of this issue.

I just wanted a 450 size Heli to practice with that had the Skookum on it.

Thanks, Dennis
