Default Selecting servos for Trex 450...Help?

I'm looking for digital servos for my 450. Must also be Futaba. Right now I'm thinking of one of the following: S3153 and the S3157. Which one would work better for a 450? Also, is this servo good enough to run the tail on a GY401B Gyro? Thanks

Hi Scott

Just curiouse why does it have to be futaba??

If its ok ill just share what set up i have now and love 

I originaly started with hitec HS65MG's on the cyclic and a logitec 3100G tail servo with a Logictech 2100T Gyro this was an alright set up untill something went wrong i thought it was the gyro as they are qute dificult to set up, so out of frustration i went and got a futaba 401 then found out it was my tail servo that was at fault ( should have checked first).

Not sure what killed the servo but didnt want to buy a second as they are quite expensive so i tried a INO-LAB HG-D201HB 9g ULTRA SPEED 0.07sec/60 DIGITAL SERVO w/ AL Wow!! absolutly briliant been there for a year now and still not a problem (quite afew crashes as well)

So i was sold on the inolab servo for the tail i thought i would try some on the cyclic following another little gear smashing event so i installed the INO-LAB HG-D202MG Metal Gear High Torque DIGITAL BB SERVO 9.7g These are available in carbon or metal gear for around the same price witch is still cheeper than the old hitech 65's and they are a much better quality servo. 
I have since bought many different servos of the inolab brand and use them in all sorts of stuff, park flyers and my Trex 500 and havent killed one yet. 
I guess my final comment is that these are avery underated servo and are exeptional value for money.
But futaba servos are good too

$34.00 US for the cyclic 
$40.00 US for the tail from my local shop www.takeoffandland.com.au

just go for metal gears on the cyclics, a 450 is a heli that maybe you will not crash a lot..or maybe yes you will, so metal gear are the best choice to avoid any future worries about damage gears.

I too have recently bought a TRex 450s and a GY48V Detrum gyro. I am using SG90 on cyclic and ACE RC 0915 on the tail for now just to get by. I have been looking at what others are using and came across this thread. Most are using Hitec servos, so am sold on the idea of using INO-LAB HG-D202MG Metal Gear High Torque DIIG BB 3 FOR DEAL $AUD120.00 at takeoffandland, where I bought the TRex and GY48V. Thanks to gee bee ace I will be going there today.

Hey Dude
I think you will find that there are Ino-lab suppliers in the US as well. Google em and you will see they are actually quite popular.

What happen regards your 2100 gyro?
I have one and I'm a little reluctant to buy the recommended Logitech servo, just because of the price.
But I'm aware that the Gyro works better with a "matched" servo.
What options do I have?
Thanks

I did use this Gyro again in two choppers A honey bee king II and a blade 400 and I found it to be a really great Gyro and compairs to the 401(some say better but i cant really notice the dif). Initially i used it with the stock servo that came with the blade 400 and it worked fine to my delight and eventually i upgraded it to the Ino-Lab high speed servo i mentioned before with great success. A real snappy tail action with virtually no drift.
I don't know about you but I thought the instructions that came with the logitech gyro were very average i did however find some great vids on you tube which made me realize how easy it actually was to set up with all servos.
I have herd that some tail servos don't like 6 volts and prefer 4.8-5 this may be what caused the failure of my logitech servo the Ino-lab servos are still working fine at the 6 volts and less than half the price of the logitech.

get something with metal gears..the best out there are the hitec servos... you will not regrest in every crash which will comes anyone. And for gyro, futaba combo is the best match.

I bought 6 hitec HS-65MG servos from Tower Hobbies for collective on two of my 450s. Tower has a quantity discount and it ended up being like $31.50 each for an excellent quality metal geared servo. I had signed up a while back into Tower's premium membership, so I have free shipping on all my orders.....icing on the cake! I haven't found any deals on the 65 MGs better than what I got from Tower Hobbies even if you exclude the free shipping.

Occasionally they'll have hot deals going on their Futaba servos .....but the hitec quantity discount (I believe it was either 2 or 3 minimum) is offered 24/7/365 and I think it's the best bang for the buck anyway...as far as collective servos are concerned.

For the tail, I use a Hitec HSG-5083MG on one heli (HG-5000) a Hitec HSG-5084MG on the other (Spartan DS-760). So far I love 'em all!

Default RE: Selecting servos for Trex 450...Help?

I know im harping on about this a bit
I agree that the Hitec servos are a good servo and a reasonably priced as well but you realy should check the specs on the Ino-Labs
The Ino-Lab HG-D202MG is as fast as the HS65 but with a stall torque of 2.5KG! as compared to the HS65s 1.6KG @4.8V. But wait there is more you also get the advantage of a digital servo for superior cyclic mixing. these servos are usually around the same price sometimes cheaper sometimes more. I know they are available from www.helidirect.com in the USA.

Also for the tail the INO-LAB HG-D201HB is as equally fast as the Hitec HSG-5083MG with 50% more torque and its cheaper, also the carbon gears have less play than the metal but admittedly the the MG is better in a crash. Compared to the Hitec HSG-5084MG Servo it doesn't win this is a great servo at a decent price.

So what im saying i guess, is if the budget is tight the Ino-Lab is a good choice for the tail but there are better, as for the cyclic you cant get a better deal.

I have 12 of the 202s in 450 helis and planes, 2 of the 201s in the 450s and 6 of the 251s in my t-rex 500s not one has glitched or failed yet. And no im not a rep.

Ok, Why should I ge the Hitec ofer the Futaba's? The hs-5065mg is only 2 bucks cheaper on average than the s3156mg. The s3156mg is rated better. Also, are either of these servo's good enough for the tail? Thanks

if you're getting cyclic servos for the trex450 look no further than the hs65mg's.   the are plenty fast and good torque.  center well and are tough as bullets.   i cant even count the number of times i have crashed with them and they are still flawless 1 year later.    you can go with futaba's if you want to but the vast majority of people run with the hs65mg's.    for tail servo get the futaba s9257.

hs-65mg's here. As for the tail I use a futaba digital 60 dollar servo. Oh yea my gyro is a 401 by the way. Works great and it holds the tail right where it needs to be.
