Thinking about trying it on my 39% 330L but would like to here some input first.

It weighs 10 oz.
moves at .14 sec.
1800 oz tq
12V battery

the battery has a separate lead to go to a LIon battery before it gets regulated.

It works at 4.8 volts but moves like a slug (6V it has 900 oz tq and moves at .29 sec). It would still have plenty of tq though.

I would like to here some success stories before I try it. I don't want to be the guinea pig

Thanks
John

Or does anyone know if it is a digital or just coreless?

Are you talking about the PS050?? if so the max torque at the max recommend input voltage (8.4V) is only 690 oz/in it can be operated at 12V but that is not recommended by Tonegwa-Seiko
I have seen all kinds of unreal torque ratings quoted for this servo like the 1800 you mentioned...but I tend to believe the ones who made it and they say 690 oz/in at 8.4V

And it uses a 7 pole motor.....it is not digital

Here is the manufacturers website

http://www.tonegawa-seiko.com/e_index.html

they respond to their emails pretty quick...I thought about this servo once but it is slow and if I remember right has a pretty large dead-band....plus for what I was wanting it for it was overkill on torque and it weighed to much...I don't have their email that they sent me with the details on the servo anymore, so I am just going by my best recollection on the above statements.

Now they also have an SSPS105 that comes in either a 12V or 24V variation..it is alot stronger than the PS050...but it also uses a 7 pole motor....maybe this is the one you are talking about...anyway the best thing for you to do is to email them, maybe that way you will get all the correct info. that you are looking for....

Click here for a thread where someone used it for a large go-kart.

I think he used the more powerful SSPS-105 which is available in either 12V, and 24-28V varieties..

Thats the servo but they had it listed at 1271 oz/in at 8.4V

I wouldn't put 12 volts on it for the power, just the speed b/c it moves ungodly slow at 6 volts and still pretty slow at 8.4

here is what was on the website I found on http://www.tokyo-hobbies.com/tonegawa.html

I think I will just put 4 JR's inline since I fly sequence and 3D. I don't imagine it would be that accurate for precision flying if it is set up for 60 degrees for 3D. Need a digital

Thanks

I have parts and schematics for both the 050 and 105 servos, and can service them if required. The info mentioned is correct, they are not coreless or digital.
