but doesn't that thing have dual chassis braces front and rear?

It does have a short brace in the back

.................................................. .....I replaced it with a JR DS8611 servo rated at 260 oz of torque. The steering is not mushy now!! :nod:

So, I ordered a new throttle servo and decided to replace the steering servo as well. I ordered some Blue Birds out of curiosity (and maybe stupidity too :). I got the 630MG for steering and the 621MG for the throttle. As I thought, the steering servo is already a 630MG, so now I have an extra. The new throttle servo will definitely be better. I made a couple steering mods that eliminated a little bit of slop at the expense of durability, or so it seems. I'll test it out this weekend. If it performs better maybe I'll post about the mod.

Steering mod testing went well. This is a fast truck, but I need to get used to handling such a big vehicle. Steering was vastly improved with the little mod. I'll try to get some pics up this weekend. No more brake problems either. The new throttle servo is fast and strong, brakes are excellent now. I will be focusing on better driving in the future :).

I saw another guy at the track who goes by the name Racer9. His ST looked dialed, he was very fast around the track with just replacing the servos. He also had some shiny aluminum A-Arms from Big Air (I think that was the name). Looked cool.

I'm looking forward to tuning this monster on the track. Should be fun.

so, it sounds as if this truck does have some potential with new servos. i hear that the steering has a bit of play in it, is this true? probably can be fixed with some shimming if so.

I wont buy Blue Birds again!!!!

The red truck on the left is my Zilla, the black truck on the right is my Mammoth St with a Proline body on it.http://pic15.picturetrail.com/VOL595.../108250832.jpg

looks great. what kind of crowd pleazer body is that for, maxx, mgt, or revo?
also, could you get a shot of how you mounted the wing?

XTM Mammoth ST
 

It is a crowd pleazer body for a MGT. Using 4 long screws just mount the GS wings supports thru the rear shock mounts into the rear gear box cover then secure with locknuts. .......... Here are some pictures.http://pic15.picturetrail.com/VOL595.../108610207.jpg

i see it now, thanks for the picture. :nod:

i may be Savage hardcore, but i might get one of this ST purely for racing... :nod:
furthermore it sells cheap here...with lots of parts around. :D

Mammoth ST
 

Well I blew my engine this weekend. I guess I should not say that because it is misleading, I wore out the connecting rod the bushing was egg shaped. The XTM 24.7 survived longer than I expected it too considering I did not break it in!! I had another big block put back a Sirio .30. XTM's are not bad motors for the price I may consider buy a few more to modify & bash with.
