OK, I can't find any digital servos that look any better than the Futaba 3150, currently $62 each at tower. The Voltz look good but have a funky mounting that won't really work as far as I can tell.

I have copied the specs below, this is my last chance to get something different if you guys have some strong input. The only drawback I see is that they are slow, but I assume that the digital performance should be a big improvement and it seems Futaba has good diigital products generally. I plan to put a 9253 on the tail.


Futaba S3150 Slim Digital Aileron Servo with J Connector. Designed for aileron applications on gliders, jets, and electric planes.

FEATURES: Coreless motor
2 ball bearings
Digitally enhanced microprocessors cut about half the response time


SPECS: Speed: 0.25 sec/60 deg @ 4.8V
Torque: 51.4 oz/in @ 4.8V
Dimensions: 1.1x0.5x0.8 in (28x13x19.7mm)
Weight: 0.78 oz (22g)
Power Supply: 4.8V (Futaba does NOT recommend using 6V)

keepin' it real

Hi stet
I can't tell you much about the quality of any of the servos you mentioned, but check the prices on this site:

Stet I have been looking for a better servo for close to a year now and the 3150 has the best features in a servo this size, like you said the Volz look good but they do have a goofy mount. I still think the 3150s will be better than the Volz because of the coreless motor but the volz have nice speed.

Let us know how you like the 3150s once you get them

Those are the best Eolo servos I have found. Actually they seam much faster than their spec number. They are a very big improvement over the Hitec servos.

Joining the long search for decent and reasonably priced servos for the EOLO, I've just discovered Multiplex. Specifications available at:

The Polo and the Micro speed look interesting. Pretty sure these are available in USA also. Does anyone have experience of them?

Dave I dont think you will see much improvment with the Polo(basicly an HS-85 with digital amp) the micro speed might be ok since it was made before Hitec bought multiplex.


Ben how long have you been using the 3150's I have been looking for feed back on these servos for almost a year!!

Thanks Buzzsaw46. I'll keep on using my HS81 and go back to the search then. I have tried a 9253 on the back of one this week and whilst it's great, it's also a bit on the heavy side, especially as I mount mine a little further back on the boom using 2 of the S5096 brackets (so when gravity attracts, the case and gears don't break when I hit the earth. Also, can take the complete boom assembly off without disturbing tail settings).

I keep getting tempted to to try the Voltz, despite their funny looking mount, as the specifications look good.

Dave quite honestly I would go with the 3150 over the Volz for the ccpm servos due to the Futaba's using a coreless motor(volz uses 3pole cored motors) the only Volz that really gets my attention is the Speed Maxx Xp due to it being optimized for use with the GY-401 in DS mode.

Thanks again for the advice. It was the Speed Maxx Xp that particularly attracted my attention, but don't know anyone who uses them. They don't have many outlets in the UK.

Been using Futaba S3101 on the ccpm. A bit slow perhaps, but seem OK for my ability level.

Preliminary Results

I got the 3150's installed

Have not had a chance to flight test as I am still working on shortening the leads and integrating the new Jazz ESC

BUT

All I can say is WOW !!!! There is a HUGE difference between these and the HS servos. Though rated at .14, they seem very fast, but the big difference is that they are absolutely crisp in their position and response. Using my 9ZWC1 (not the best for ccpm), I ran the swash up and down as fast as I could and the swash stays very flat, no wobbling or sluggish behaviour whatsoever. The servos move to the very slightest stick input, exactly and evenly amongst the 3.

Actually, now looking at it, I am under the impression that these servos might make a very good tail servo too. If you ran it at 6 V speed goes up to .11, but I think with the improved resolution and all, they might actually do very well at 4.8. The 9253 I have on there now is causing me to have to move the battery further and further forward to get the CG back in line.

I can tell right away that this heli will fly and feel so much better than before. I'll report back once I acutally fly it, but from what I see now on the bench I am certain I will be more than delighted.

3150, well worth the price

keepin' it real

I use 3 Hs 81 MG's on the head and I think they're fine for me. I think the size of the Eolo will always make it continuous input model. Or maybe I was really lucky and just got 3 good Hitecs in the first place.

Mick, No doubt you will always have to make minor adjustments in flight but it is much nicer when the servos move the amount you want and return to a true center, The HS 81's will always have a bit of slop when centering so will the 3150's but not as much in fact it could be as little as 1/3 the slop.
