ben goodfellow 1 Posted April 23, 2013 Share Posted April 23, 2013 i dont use anything but savox micro/mini servos in my smaller planes from the first flight i used them i could see and feel the difference and they are not as expensive as you think . i seen some one flying a 50cc petrol job with 3003 on everytthing which is just plane danerous . for what you can get a good high torgue digital for it def worth it Quote Link to comment Share on other sites More sharing options...

ben goodfellow 1 Posted April 23, 2013 Share Posted April 23, 2013 well on my experience with savox you cant go far wrong ave about 20 of them. I will def buy more of them Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted April 23, 2013 Share Posted April 23, 2013 In the old days LOL, we used to have nothing else but standard servos such as Futaba 148s, and we all flew models as big or bigger than that with them. And I might add, the standard radio supply battery in the model was a simple 4 cell 500mahr pack. Gawd these kids today eh LOL Quote Link to comment Share on other sites More sharing options...
Mark R Posted April 23, 2013 Share Posted April 23, 2013 Savox definitely get my vote. Put a pair on my Acro Wot for aileron use, and wow the roll rate is amazing and unlike some digitals they dont seem to spend all the time on the ground 'buzzing' or hunting for centre. But then again i have also used 3001/3003 on all my other models upto 4 stroke 90. Never had stripped gears or any crashes due to failure. Plenty of crashes due to dumb thumbs tho!! Can you get digital thumbs yet? Quote Link to comment Share on other sites More sharing options...

Allan Bennett Posted April 24, 2013 Share Posted April 24, 2013 I don't see why analogue servos should be "dangerous" compared with same-size digital ones. I use digitals on my helis on the channels that are controlled by gyros (i.e. all channels on my flybarless, and rudder only on my flybarred) because of their faster reaction time. But everywhere else I use suitably-sized analogue ones. Digital servos, I believe, react faster and hold their position more accurately than analogue ones. But we're probably talking about nano-seconds and minute movements so, personally, I don't see that they're worth the extra money for a Sunday-afternoon club flyer like me.

Chris Bott - Moderator Posted April 24, 2013 Share Posted April 24, 2013 We must never forget that the faster reactions, higher accuracy and better holding power come at a price. That price is in battery consumption. With digis, if we don't pay proper attention to selection and care of receiver battery, switch and wiring, then we can cause problems and have an installation that is actually more dangerous.

Steve Hargreaves - Moderator Posted April 24, 2013 Share Posted April 24, 2013 Chris makes a good point.....just to add to that its worth remembering that what really matters is the ability of the on board battery to supply the necessary current without dragging the supply voltage down too far. In this regard it really is the case that bigger is better. Physically small batteries such as AA cells can struggle to maintain their voltage under the transient loads imposed by powerful servos....

TheFlyingCrust Posted April 24, 2013 Share Posted April 24, 2013 Another point. The analog servo's I have all 'jump' when energised on turn-on. If they just happen to be at the limit of throw (say a closed throttle, CROW brakes eyc...) then damage to the servo is a distinct possibility. Whereas the Digital's I have don't 'jump'. I think it was Slopetrashuk who highlighted this issue in a thread on setting failsafes. To date this hasn't been a problem for me - but worth bearing in mind.

Yes I well remeber the red and blue and linear ( they were v good actually ) servos - I was merely making the point that there is a lot of snake oil around this hobby of ours these days. The only thing I would add is that the price of a typical bog standard servo back in those days, would probably be able to buy a few really nice powerful, metal /karbonite geared, digitals these days, so its a no brainer really.

Flite08 Posted April 24, 2013 Share Posted April 24, 2013 Doesnt the use of gyro rx's demand digital servos because of their constant movement Quote Link to comment Share on other sites More sharing options...
Ben B Posted April 24, 2013 Share Posted April 24, 2013 I quite like analog servos because the slower movement makes the plane fly a bit smoother in my expeience. Equally where rapid speed is required nothing beats a digital. The small Savox servos are cheaper because they're not made to the same standard as the normal size servos. The Savox 0256, for example, are the same as the ones used by Align in one of their smaller choppers (I think the 250) just rebadged.

Tim Mackey Posted April 24, 2013 Share Posted April 24, 2013 I think that for the average club flyer, in the typical model, didgitals are completley un-necessary. The very vast majority of flyers would never be able to tell the difference in response /speed time and for anything other than perhaps high performance heli tailends, they are snake oil. I would say that if you believe that paying £277 a metre for premium speaker cables can really deliver VFM, then go buy expensive digital servos for your models!

bouncebounce crunch Posted April 24, 2013 Share Posted April 24, 2013 Never owned or even considered digital servos, I use Hitec and JR and have never had a problem. all of my powered models are 54fs/ 46-2stroke size and below, and my gliders are not speed machines; i must add that i am only an average flyer not a competition guy so the expensive stuff i don't really need.

Alan Wood Posted April 24, 2013 Share Posted April 24, 2013 Basically the only advantage with Digital servos is thier holding power the power to the control surface varies with movement on normal servos but its more constant with digitals. Digital doesn't affect speed, it just tends to the that top spec servos are digital. Speed and torque are the biggest factors in choosing a servo. I can't speak for others but I can easially tell the speed of a fast servo vs a slower one. There are so many servos because they all have a time and a place that suits them best.

Alan Wood Posted April 24, 2013 Share Posted April 24, 2013 Hangar 9 Pulse XT 40 with 3152's are a good match. The 3152 is a standard spec digital servo, same speed as a 148 but with more torque. You won't notice much difference in performance on that model with anything above that. :D Quote Link to comment Share on other sites More sharing options...
Glyn R Posted April 24, 2013 Share Posted April 24, 2013 I have used small digitals because they tolerate 6 volts better than analogue. the ubiquitous 9gramme servos are often not happy on 6 volts. I like to use 6 volts to give more headroom for the 2.4ghz Rx. O f course you dont have to pay.

Steve Hargreaves - Moderator Posted April 24, 2013 Share Posted April 24, 2013 I'm having a play with some of these Corona servos. 8kg,cm metal geared....they just happen to be digital. Pretty impressed so far..... The main reason I went for them is they are suitable for higher voltages & thus help to reduce my paranoia about using a 2S LiFE battery to power the on board radio... The irony here is that being designed for up to 2S (7.4 Volt) Lipos they are a little slower on a 2S(6.6 Volt) LiFE battery.... One day SOMETHING will work out My way....
