Also sounds like you are running too rich. Lean the HSN.

Make sure all the connectors on the receiver are all going the same way...The black wires all should betowards the outter edge of the unit

RE: major t-maxx problems
the servos move but the the steering one doesn't fully move to turn the wheels, when i put it back together i forgot to tighten the slipper clutch. so now it will go in a straight line but the brakes are still partially engaged.

yea i leaned it out i think it is the glo plug, would a glow starter be better than the one on the ez-start.

Also check that you didn't over tighten the pivot ball caps. If they are too tight,the servo will not be able to turn the wheels.

RE: major t-maxx problems
Don't get discouraged Joe. I thought I would go bald the first couple of times I went into mine. It really sounds like to me the pivot balls are to tight on your steering. Just loosen them up till you have a little slop in the wheel. If you put your finger on the joint of the pivot ball you can feel the movement when you rock the wheel. As far as the throttle-brake linkage, I would get the engine or throttle set up with a 1mm gap at idle and fully open at wide open set first with the brake dis-connected. Then set the brake. All of these adjustments done without starting it or any-thing. Like I said it can get real confusing but after a while, if you like it as much as I do, it gets just as fun to fix em as it is to run em. I get plenty of time to fix em too with a 14 year old that loves to drive em or should I say destroy em. It's all good.

RE: major t-maxx problems
I get enough of that from these two trucks! I spent most of the day making a new course for my son and ended up with a busted exhaust manifold, broke pull-start, and a broke rear shock tower!! Got to make those courses a little easier! To the work bench I go! By the way did you get yours going?

RE: major t-maxx problems
Joe ....snoking has a point about the pivot balls possibly being too tight.
They can be tight two ways..The ball can be set too close to the a-arms and the pivot ball cups could be too tight..
Try turning all front 4 pivot balls out 1 turn each and readjusting the streeing track straightness with the turnbuckles..
WhenI set my cup tension I snug them til I feel resistance then back off 1/8 turn..Sort of the same thing you do to set spindle mounted wheel bearings on a real car....
I put an end to all my steering problems in all my T-Maxxes by adding a second stering servo to them....now my bashers steer like the vid below...sorry for the poor vid quality..It was taken with my cell phone
TheT-Maxx in the vidjust has two standard Traxxas 2018 servospowered by6 volts 2450 mah of power and stock Traxxas 3 channel remote.My BiggMaxx has twin OFNA metal gear servos;-So does my MGT..The other Maxxes have Ofna's,HiTechs and Futabas..I also noticed when you use a true 12 voltsofbattery powerin the transmitter it actually works very well..most aa batteries are only 1.2 volts making the transmitter 9.6 volts with 8 batts...

RE: major t-maxx problems
That is pretty cool. I have heard about two servoes but have not seen it. Couldn't see it in your pic so I cleaned it up. Hope I can get it up here. Think while I got mine on the bench I will have to try it. Thanks

RE: major t-maxx problems
Heres a few better ones for you...I took thisfrom the thread i posted...i also did the dual steering servosin my MGT8.0 and soon Im gonna do my Savage SS
....The surgery was a success in less than 2 hours from beginning to end and I even had time to snap some shots of the action....
I removed the receiver box , marked the spot with a sharpie like dye-kem , scribed out the shape of the servo and cut it in with a dremel with cutoff wheel and used a drill with 1/8 drill bit to drill the servo location holes...one of the markings was a lil off but it was corrected when drilling it out.
Heres the servo hole cut out and what it looked like.I test fit the servo and then added the other servo horn..I guess youre noticing that the surgery was performed with the truck as a whole still...It was easier for me to do it that way so I can get out to test it sooner than later....
For the servos I went with OFNA SX-0002 metal gear servos...They have descent amount of torque and reliability for the price...I got both servos for 30 bucks shipped with the "Y" connector to hook them together at the receiver box.
For the receiver box I used a spare set of throttle servo brackets to attach the receiver box over the servo as seen in the picture below..

RE: major t-maxx problems
heres how I did it.........
To acheive the dual steering servos the following tools are needed to complete this task: Dremel toolset with cutting wheels and the normal r/c car hand tools for dis-assembly....
For supplies youre gonna need a secondary bellcrank assembly,secondary servo plus additional servo mounts aswell as miscellaneous extra hardware like screws/nuts and washers and a y-connector for hooking the two servos together to add to the receiver box unless you have a receiver box with a 4th auxillary space like the Revos have...

if you dont have the talent or tools to do the dual steering servo set up you can buy [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXTHR3&P=ML]THIS[/link]

RE: major t-maxx problems
why with revos people take a servo out and just upgrade the single one, and with tmaxxes apperntly people are now adding another servo?

RE: major t-maxx problems
Two steering servos work for the cool factor but just like the revo you will have the continuing problem of the two servos fighting each other for center if not adjusted exactly.
I have done the two servo mod many times and each time I always revert back to a single high torque servo.
1 servo uses less power, is easier to adjust, lighter and less parts to break.
Even with my puller maxx I reverted to a single high torque servo. 1 was plenty of torque to turn even the Jumbo Kong’s.
