Hi all,
I just joined the board after getting my Phoenix parts a few days ago.
I am still collecting all the needed extras and $$.
It just happens that a friend of mine who is getting out of robotics gave me 9
5990TG’s (really 
).
I have been around tech and computers a lot, my last robotics incursion was many years ago, so I have seen many changes.
My question since I do not know much about servos is, should I save for the remaining 5990TG’s or go with 645’s…
Thanks
Felix
Hi,
Since you already got 9! of the 5990 TG’s one suggestion would be to buy 3 more and use them for the femur and tibia parts. And 6 645 for the coxa parts.
BTW, you must have a VERY good friend who is giving you 9 5990TG 
Yeah! That what I was thinking… Those babies are expensive!
I would do the same as Zenta said. Then you could buy 6y more if you really want to have all 5990’s.
Thanks for the quick response! Yes he is a really cool guy.
I know they are spendy. From reading the specs I can see there is a difference in the fact that the 5990TG’s can operate safely at higher voltage (7.2), so it will be part of the design consideration if I should go all 5990 or put 645’s in the mix. But programming wise, am I getting in trouble here?

ugh… 18 5990s… I get a headache just thinking about it 
As far as I know, programming wise, you won’t run into any problems just by using different kinds of servos, since they’re all controlled the same way and have the same range.
Did you ever get them into your Phoenix? If so how are they working out? Has anyone else used them in a project? If so how long can you run them?
with this servos is phoenix a weapon 8)
30kg/cm on 7.4V is realy heavy if you think 645mg have 9kg/cm
u can cut your fingers between femur and tiba 
realy cool this servos but they cos 130 euros, 150$
but ony great
or you can buy 9 more 5990TGs and have a SUPER PHOENIX!
Watch those fingers during testing…
