I'm completely new to Traxxas ... I've been a Team Associated guy since 87' so needless to say I look at this thing like . I have a few questions and would like a few tips so please feel free to keep this going! I did a search so I'm sorry if this is a re-post! Here are a few question's ..I'll add more as i get that far in -

1. What do people use to make these turn better ? I see alot of 208 tq oz servo's , do these work that much better than the 144oz's with 40 series rims and tires ? ?

2. How much power will the receiver allow ? I'm thinking about a 6.0 volt 2000 mah battery to add more power to the servo's to help turn the huge tires.What does everyone else use ?

If you're going to run the stock chevron tires, I've found you need 180inoz to turn efficiently - more than that is overkill that runs your rx batts down that much quicker. I went with lighter tires and rims as well - SportMax wheels and Sporttrax tires losing over almost 2 oz per wheel if I remember the numbers correctly. That alone made a big diff in the way it handled and accelerated.

I've had good service from the Ballistic rx pacs they make for Tmaxxes - I have an old 1650 that lasts for complete weekend of running. I think they are up around 2500 or 2700mah now. This is made into the stock batt box and replaces the stock one. Get a new switch with a separate charge lead and all you will have to do is just plug it in, no more taking the batt box apart to re-charge batts. The rx is not worried about power - its volts. As long as you don't change the voltage, mah won't matter - mah is more about how long it lasts.

6 volts......A Must

More torque = more better Especially with 40 series.

I have the older 2.5 as well as the original pro .15 (not sure about the newer ones )but there is a mod for steering. It involves grinding the stop on the knuckle (for more throw). I'll look around and see if I can find it again.

I found to that tires will probably make the biggest difference.
17 or 23 mm hex....a must
I like truggy type tires....a little more narrow and available with different offsets.

With the right setup......a very capable truck. Reading around this forum and it seems like there are not to many "fans" of the maxx line of trucks....But I think they give up to easy. I now race Revo's (But I do keep the Maxx's as a back up).

You need to get a high torque servo. once i did i could to a 180 in like 4 inches

Ok, sounds great! Thanks for the great advice , so steering is the main issue ? What about upgrading to the 3.3 from a 2.5R... what all is involved ?

A 3.3 is drop in ready

I would go with the O.S .18tz over the 3.3.

If you go 3.3, get the MIP clutch - the 3.3 works the stock clutch pretty hard and will make it slip. MIP clutch ends that prob.

wow guys, great advice - care to share pictures of your rides ?

What annoyed me the most about my Tmaxx 3.3 was the soft rear suspension. And that annoying wheelie bar. I suggest getting some good shocks with the right springs and some good oil for the shocks as well. Or just buy a REVO 3.3.
Thats what i am doing

Heres mine..

Its just a web album link, dont freak out

The 3.3 has a slightly better bellcrank system than the 2.5. But I still believe it might be wise to upgrade the steering servo anyway. Also, a better radio with adjustable servo rates is going to be my next purchase.

The 3.3 comes with larger tires (sits higher) than the 2.5, and is very tippy at speed. Take the wheelie bar off if you are offroading it, or you will lose it when it pops off on it's own. Aluminum front bulkheads and stronger shocks are also well worth the money.

I haven't had mine for long yet, but those are the main things that have caught my attention so far.

imo i would start with rpm arms,aluminum bulk heads,big bore shocks,and a 2.4 radio system.then start a spare part box with some extra hinge pins,spur gear,assortment of bearings,and screw kit.im not saying this is all you need but its a great start and pending on how hard you drive you will know other parts you may need or want in reserve.with this set up you should be able to do some moderate bashing and be safe

Hey guys what glow plugs are you guys running ... right now I am a little puzzled ... The kit says run a medium heat glow plug .. i did not know this until AFTER i already purchased a LC3 (HOT plug long reach) my stock one went out and i went ahead and used it ... Damn the truck idles better and has much better low end!! Whats the upside to a medium heat range plug ?

I always had pretty good luck with the lc3's in my 3.3

Alot depends on the weather conditions. If its working for you ....run em.

nitro % has alot to do with it as well.......generally the higher the % the colder the plug......But go by how its running.....If its good don't worry.
