Blade 400
3D G110 gyro and compatible servos

Hello I'm thinking of getting a futaba s3154 servo for the blade 400 to give the tail control a little more beef without spending too much money.
I was wondering if it was compatible with the stock eflite g110 gyro on digital. I would like to use the digital switch on the gyro to maybe maximize whatever precision it has left. I know it's not the hottest gyro but I think the stock eflite servo it's paired with doesn't let it do much. The eflite one is supposedly digital despite they don't center very well and the gyro is set with the switch on standard.
I know JR servos would more likely work but the ds290G has pretty low torque.

I've recently added the Hitec HSG-5084MG to my B400. Although I fried the ESC and have not been able to test it, but at .07 sec its plenty fast enough. It was a bit of a pain to mount. Had to run the TR pushrod at an angle, but it works fine.

On that side note of the esc, how did you fry it?

Reason I ask about the servo being compatible is that i'm not sure the signal will jive between a horizon and hobbico product, as the gy401 will not accept JR servos since there's a different pulse, according to the note on its tower hobbies listing. I wonder if it's the same the other way around on gyros in general or if it's just particular to the gy401 and jr servos.
I'm curious what the difference is between digital servos in general when it comes to gyros, I know there's framerates that some servos can handle, others cannot. I am of the impression that digital servo means it can handle doing gyro commands at the high rate just as long as they're digital, just standard servos can't and might ruin themselves. I'm not sure if all digital ones can do the job or not though and might ruined like a standard servo would. The stock e-flite 'digital' servos don't seem to be the kind to handle high gyro framerate..I dunno, maybe they are but my switch has always been set on standard.

Do not know how it fried. I installed the Hitec 5084 servo, went out to test it and toasted on spool-up. It was sent back to Horizon and they sent out a replacment.
I'm not going to use it though, I had a CC Phoenix 25 tha I installed. It seems to be working ok.

ahh, perhaps that servo asked much of the ESC's bec. I installed an extra bec by hextronik about $7, running from the battery connection, relieving the esc of bec duty because of reports of the eflite esc smoking out. if you do that, take out the red wire pin on the esc connector so that the two bec's won't fry each other or double the voltage.

anyways as far as the servo gyro combination is concerned, I guess it helps I read the blade 400 manual. the digital servos that come with the 400 cannot accept 275mhz pulse rate which explains why the gyro is set to standard.
now all i wonder is if the futaba s3154 can accept 275mhz? I already tested the servo out on normal and it works a heck of a lot better than the ds75 eflite servo, so the signal isn't off on timing/polarity. but i would like to use the digital switch if it means even better performance.
i don't see how the JR 290g would do any good since it's torque is pretty low (lower than the ds75 servo) and the futaba one with more torque is having a hard enough time going backwards with wind (although a bit better than the ds75 servo).
