i just bought a nice little T4 and i plan on racing it some. it has been about 20 yrs for me so i guess i am out of the radio gear loop. is this a decent servo http://www.hobbypeople.net/gallery/440702.asp or should i stick with futaba, hi tec or jr?

You dont want that. Futaba, JR, Airtronics, KO, or Hitec are fine.

I would perfer JR, or KO,

Cirrus are OK...
I personally like the JR 550Z or 600 Series. Good Price. Metal Gear. Very reliable.

I have a JR 4800S in my T4. Plenty quick and powerful. Not too expensive.

is the jr 590 ok? i dont really want to go over 40 bucks i have a futaba 3003 that gets me around the track just fine just a little more speed and strength is what i am going for

jr servos are great.

I believe the 590 will work just fine
