Default Servo consumption

Hello All,

Well I am getting close. I have set up my Raptor 50 according to all I have read on this and other sites. Once agian thanks for all the help along the way. I am using 8717 servos for all five controls. I have checked to see that all linkages were free moving and I used a Hanger 9 amp meter to measure my current draw. I am wondering if anyone else has done this with these servos? They seem to buzz a bit when first turned on but after reading a few posts I am led to believe this is normal.

The current draw for my installation is as follows using full movement of the control surfaces:

Stationary no movement - .20 - .25 amp
Throttle and collective - .65 - .70 amp
Rudder - .59 -.67 amp
Airelons - .48 - .62 amp
Elevevator - .48 -.56 amp

Now I am using a 4.8 volt 2700mah NiMh as per LHS suggestion.

Does this sound around the norm?

Thanks

Your post sounds like you caught some wasting disease from your servos

I don't know the answer to your question wish I could help.

Yeah I know what you mean, but at the advice of the LHS that is what I bought. I had a different one picked out for the throttle, but they suggested to go with all the same, except the gyro servo which is a futaba 9256. I think there is a real sickness that gets to you in this hobby. I have already got about three crashes worth of parts ready for when I begin to fly it. Due to the long wait for my radio I have been getting a lot of sim time so hopefully they will collect dust.

And remember, The last suit you wear doesn't need pockets!
