Futaba 3010 Servos

[hduk]

Hey All,

Ive read quite a few posts on different forums about the Futaba 3010 servos. Anyone have any issues using them with the Align reg?

Ive had a bit of a panic, they say they can draw up to 2a each, that seems a lot for a servo and given the reg supplies 6a im worried this might take out the 2.4 rx if they hit their peak.

Any pointers? I know the futaba site says use Nicad or make sure if using NiMh or Lipo that they are up to the job. Do i fly it or do i change the servos?

Thanks in advance

People have been running 8717's on the 2 in 1 for a long time now, if they dont draw 6A then 3010's wont. I wouldnt worry about that at all.

Thats what i was thinking but wanted to make sure as there must be some reason Futaba have emphasised the draw.

Maybe i need to rig up an ammeter and take a few measurements under load.

the ammeter is all good and well, however how are you going to simulate flight loads. your best bet would be a datalogger, I wouldnt bother myself as I'm sure you would be fine. What is your style of flying?

Id probably describe my flying as "an enthusiastic effort at 3d with mediocre results" (basically a wannabe 3d pilot, got to start somewhere).

I was thinking of just manually loading the head a little just to see what sort of results slight loads produce a simple weighted rig would do it then with a base line you could calculate the increased load draw.

This is the quote from Futaba "This 3010 standard high-torque servo can produce high-current draw from your batteries.
If using NiMH or LiPo batteries, make sure they are capable
of delivering approximately 2A for each servo."

Problem is it doesn't say what the reference load is to produce 2a . If you assume that the 2a is @ 6.5kg ea do you think load on a head is anywhere near that? thats 19.5KG i reckon the links would give out before that.

I really don't know what the loading would be, I wouldnt worry though. Futaba and other manufacturers over exaggerate their specs. 2A off a non digital seems a little excessive though.

Thats true, and im sure the servo wire is only capable of 1.5a.

Having said that the thought of flying it is making me a bit nervous as it used to glitch on 35mhz, as did other aircraft at the field in the same place but knowing about the current issue is making me think "what if the draw is causing the glitch" not so bad on 35mhz but if the 2.4 rx lost power it would brown out for a few seconds. Might just try it and see but a lot of money to risk
