e-Align T-REX 250-450-500-600 > Align Servos

Hi Folks
I have noticed that many people are not using the Align servos with thier T rex
I this because they are no good to use. (possible slow or week or fragile)

would they still be suitable for a beginner and could they still be used for the ccpm mods.

They seem to be the cheepest around available in combo deals with the T Rex

any help would be apprciated.

Thanks
Ben

I use Aligns' 9g/6g servo set...

i run them. i heard the same thing. they're ok.. i finally was able to buy a full compliment of BOTH futaba 3107s and HiTec HS-56HBs and will be comparing the 2 sets on different rex's so i'll have a better judgement of the Aligns by then. don't hold your breath for my experiment - i'm in no hurry to do it..

Here's what I have found with my Align set of servos:

- I now fly 3d.. yay me! and learned and continue to do so on my align set.

- figure 8s are nice and smooth with good control. i can get my rex to fly a nice flat figure 8 w/my Align servos

- started having glitches on the one that controlled the elevator. replaced w/another Align 9g servo and all was good.

- i stripped the Align 9g pitch servo from who knows what. I bought the gears (which seem to be available everywhere a rex is sold now) for real cheap so just opened it up and replaced them - all was good.

- i broke the "rabbit ears" of my tail 6g servo from a crash that cause a boom strike.. threw that one out and replaced it w/a Futaba 3107 - I think it's a little better. the Futaba seems to have more torque and authority...

bottom line: get'em if you're looking for a cheap set (note they're probably comparable to the HS-55s in price & product). if you don't mind parting w/a couple more bucks get some 3107's. if you don't mind forking a couple more bucks, get the hitec hs-56hb's (they are ball bearing and have karbonite gears [stronger] and should last a long time). both of the latter i'm sure are slightly better than the align's but i'm betting a beginner couldn't tell too much difference - no offense..

for more info on the two latter servos, see this post http://www.runryder.com/helicopter/t145782p1

Stripping the pitch servo does happen on the TREX,
you may find your collective action is stiff or notchy,
I found the notch was the slide block going through the pins,
I filed the guide holes with my wife's nail file,
that made a huge difference
But I run the 3De CCPM setup now...

A friend is having problems with his CCPM
the GWS Naro Servos don't appear to be identical,
subtriming them is terrible, going to change to Futaba
The GWS pulls twice the current of my Futaba S3108's,
the BEC gets warm just on the bench doing the setup.

The Futaba S3108's are so much more consistent
and have a very smooth action with fine graduations,
my CCPM TREX with Futaba S3108 flies so much better
that the one with the GWS Naro's (constant cyclic corrections)

Jafa,

I am building my TRex now with 3De CCPM - and I am going back and forth on servos to buy. Can you tell me how you mounted your 3108s? From the back of the frame? Any pics? Thanks!!!

Comment to Jafa..

3108's hm.. i heard 3107's draw some juice.. maybe 3108's would be better.. i can't tell much from the chart: http://www.futaba-rc.com/servos/futm0029.html

would you know how these two compare?

JR servos

I am thinking about getting the JR6102 with the JR 241's. It seems like a good deal for the package. Has anyone used the 241's on the Trex?

How about using the align servos for a ccpm conversion?

If i were to leave the T Rex in standard form then i beleive that the align's will be fine . (for a beginner)

How do you think they would handle CCPM ?

If i am correct then they should be a little better off due to the loads being spread between 3 servos, should this help with the pitch servo gears stripping.

Thanks to all thise who have posted

Cheers

hmm Wazzer... that i would not do.. i've seen my align servos strip too easy to trust them with direct swash control. i've also seen when they go slightly bad, they have a little "click" in their action as they move side to side. i'm sure it would work for the 1st few flights without crashes, but i've already bought futabas 3107s & hitec hs56's in prep for my ccpm projects.. translated; servos you can trust...

I cannot say what the current draw of a S3103 or S3107 would be,
I have a servo tester but have not had these servo's
to test or compare to the S3108's

A friend is getting S3103's in a few weeks,
so I will be able to test/compare at that time.

My elevator servo was mounted from the back of the plate
to bring the horn closer to the plate and reduce the offset
to the TREX elevator lever

The other two servo's were mounted normally,
from the outside...

This picture is not great but you can get the idea...

Align does not have as much travel than HS56HB

thanks for the note Jafa..

as a side note, i had a crash this wknd which broke the gears inside the Align 9g which handles the pitch.

i had previously dremeled out the pitch holes on the frame (the elongated oval ones) which hold the elevetor holder arm in place, but never took advantage of the new full travel of it (of course never reaching pitches over 9-10deg)

i mentioned i had some HS 56HBs laying around and a few Futaba 3107s so i disconnected the bad Align servo and started comparing the travel between the 2.

clearly, the Hitec HS56 not only had 10-15deg more travel than the Futaba, but it came with 3 servo horns (one being much longer than both the Align and Futaba) and was very suitable for the job.

after mounting it up (the Hitec), tested it's pitch range and of course it was using all 100% of the travel which means I've just managed to increase my pitch by 2-3deg each way (pos/neg).

the flight test showed that the tail rotor/gy240 could keep up with the increased pitch which resulted in a nice stable verticle climb at full throttle/full pitch - yay!

so with the Align 400S and this increased pitch, my rex has much, much better climbout than ever before. not to mention, the pitch seems more contollable now with the HiTech at the helm.

Well maybe you can't, but the servos can: http://www.runryder.com/helicopter/t156369p1/

Has anyone seen anything like this before?
