Does LogicTech have a website?

S3154

I have just installed a new futaba S3154 digital servo in my hornet X3D pro , and still can´t believe the results, the combination
GY 401+S3154 , just holds the tail rock steady , I can even hover with just one hand on the ciclic stick, it´s just amazing.

One thing I noticed right after landing is that the servo is warm , I don´t know if that´s normal , and that´s why I am writing this .
Does anybody know something about this servo? , can anybody tell me if this is normal?

I don't know if it's abnormal for the servo to be warm but you may want to try Futaba support?

Just curious, what ESC are you using?

One of the MaxiR guys mentioned servo heat as well. I only have a couple short flights on mine and forgot to check the servo

I'll try to remember next time out

re. S3154

Hej Raz

Right now I´m using MS Composit´s MS 114 ESC , which is the ESC they recomend for their motor , MS 300 .

helikopete,

Did you mean to say MS116? If so, I'm glad to see that the BEC isn't being overloaded by the s3154's. Did you say you are using x4 s3154 servos?

Hej RAz

Well , yes, it´s MS 116 , and , no, I´m just using one s3154 , all the rest are Hitech HS 55 , I don´t think that the MS 116 can handle 4 S3154.

If there´s somthing I like from the MS 116 , it´s the soft start , even if it takes longer time for the rotor to catch up speed.

S3154

Hej Raz

I don´t know if I mentioned it yesterday, but I found the reason why the S3154 got warm , and it´s because the gyro lead got caught by the main gear , and it shorted :-) , no wonder .

This is what I guessed (The MS116 being unable to handle x4 s3154's) The specs list 3 to 4 servos but I'm guessing it refers to analog.

I'm not sure how many amps each s3154 draw but I'm thinking I may be able to get away with a Jeti Speed 11 ESC. I'd like to try x4 s3154s.

HSC,

The SPIN 22 operates between 2-4 lipo cells up to 22amps in current. The BEC specs are identical to that of the SPIN 11 (5.5v at 2.5amps)as well as operating between 2-4 Lipo cells but of course allows up to 11amps in current instead of 22amps.

I don't know how many amps the heli draws on average or how many additional amps the heli will be drawing with x4 s3154 servos versus that of x4 s3110 (for example) servos? Guys, any help here would be appreciated.

I have read that ESCs are more efficient if they are operating at or above 85% of their amperarge limit. I feel I may just be squeaking by with the SPIN 11.

I have the Logictec 6100/611 combo in my brand new TRex600 and while I'm not able to compare it to anything but a 401 (I have three of those) it seems so much better that it is a bit of a revalation, really! But I will say that the Logictec is very high quality and performance and it was incredibly easy to set up and use. I would guess the 2100 is also great based on that. I bought it (the 6100) from Heliproz.com. I am excited to hear about the new Futaba 3154 and will get one asap. My Hornet is nose heavy with 1320 lipo's and HS-50 on the tail anyway.

I got a couple flights on my 2100T today, and it's pretty good I get a little bounce on left stops but the right stop is nice and solid. A little more tweeking and I'll get it dialed in.

Guys,

Henry of MScompositusa.com has confirmed that the BEC in either the MS116 or SPIN 11 should handle x4 Futaba s3154 Digital servos!!

axi 2212/12

Hej Raz

I have a question 4 U
I am considdering changing the motor in my hornet , right now I am using a MS-300/20 , it gives about 1820 rpm/V , but it "feels" somehow underpowered , I haven´t check the weight yet, but I am in betwen limits ( I think) , my battery is a 3 cell 1500 li-po , no extra glue or nothing , that adds up witght , everything assembled as per the instructions.

I am thinking about buying a Axi 2212/12 motor, that gives about 1950 rpm/V , and draws 14-22A , instead of 8-12A from the ms 300.
The other difference is that the axi 2212 is slightly longer than the other , otherwise they both have the same diameter and shaft.

What do you know about this motor?, and would it be worth to change it?

Peter

Pete,

The Twister 300/20 should offer plenty of power. I wouldn't guess it's your motor. I assume you mean 1820rpm at hover in idle-up 1? I havn't had the chance to tach my rotor rpm but a few things

What are your throttle and pitch curves set to?
What ESC are you using? Is it in Governor mode?
Are you using the Brass pinion? (I'm forgetting the number of teeth)

1820 is the Kv of the 300-20/2208-20 motor - I think the 2212 would be like a 400 motor and ballistic power in a Hornet - Might make sure your equipement can handle the amps and all - Maybe someone more knowledgable about this like DH can comment on using bigger motors - I'm not too keen on the math and just follow the herd mostly - I put a 400 in my BCP once and it was a spiralling missle - I had to really tame it down.

motor

Hej Raz

I am using the Ms composit´s ESC for brushless motors that came with it, I am using it in standard mode ( in governor mode it doesn´t give you the rpm needed to fly hard 3d) , and yes, it´s the model that gives you 1820 rpm/v , and also yes, I am using the brass pinion that came with the motor ( I also don´t know how many theet does it have :-) ) , my throttle curve is sort of like this : in idle 2 90 , 90 , 90 , 85 , 70, 85, 90,90,90 , and even though I don´t have a pitch gage for such a small blades, I have set the values , as not letting the rotor to bog down due to too high or angles , in + and - , but still I can´t achieve the kind of climb outs I am used to with my raptor , and also when on inverted , it can barely hold itself in the air , and yes, I have noticed how unstable it is on inverted hover :-) , so that´s why I was considdering a slightly stronger motor.
