This used to happen with the older xray cars as well.
The linkage doesn't bind in the slightest. The servo is infinitately hard to spin by hand even out of the car altogether.

You can try loosening the servo case screws. It could be the case top cover is causing the binding issue.

Ok, Ill try that when I get home.

When the servo arm is still, it takes a TON of effort to get it to start spinning.. once it is moving, it seems almost normal, but still pretty stiff. The moment the momentum of the spin is over, it locks back down again.

Looks like you have plenty of room to me. My layout is tight with motor fwd option. If you grab your tires and turn left to right by hand, it should turn smoothly with a 9551. As others have said, check your servo linkage to be sure it's not binding up.

Same size (unfortunately), but no antenna. Not available in the US (yet?), but works great with the US 4PK.

Hey Captn America, just a observation, if you where to move your antenna mount ahead ever so slightly, you could tuck the reciever in more for a cleaner look. Just a suggestion.

Here is a PIC: Question... is the 9551 supposed to be so tough to manually turn? My normal crappy servos turn really easy.. this guy is SUPER HARD!

How long have you been using that servo in that position?
I don't fancy it's chances of surviving long with that angle on the servo mounting screw nearest the front of the chassis

Why don't you just turn the receiver on it's side so the plug holes face the back of the car?
Or you could try the 'flipped' drivetrain idea so the belts run the other around, the front belt would end up nearest the lipo while the rear belt would move to the radio side.

put the servo posts in the closer holes, and for gods sakes take the preload out of that servo ear!!! next, put two fingers on each tie rod like you were picking up a tooth pick. rotate each tie rod, they should be reasonably free. if one is exceptionally tight, replace the plastic ball cup.

cheers

There is no preload on the servo ear..its not being bent if that is what mean.

They are completely free.

Has anyone tried the Rubber-Spec Conversion Set - 38T Pulley?
Any feedback?

Does the Lipo balancing chassis weight will fit with a Hyperdrive lipo tray?
Any pics (installed)?

Sorry for the newbie questions... just planning on getting back to sedan racing after 10 years. So much to catch-up. Will get a T2 '009 and I am just doing my homework about what I need to purchase.
I will be using SMC 5240 hardcase batteries. BTW what are your recommendations on servo?

LRP Comp TC esc, Tekin, other(s)? Brushless (open mod) motor (I need something in the 3x)?

I dont think you can use the Hyperdrive lipo tray.

Revo523:

Do you like how the battery sits with the lipo weight balance kit?
How would it compare with a Hyperdrive tray?

I am just debating which I should get. Does it help and make balancing the car easier, compensating for battery weight or it simply keeps the battery in place better?
