i like my t-maxx...but i will havto admit i had to put 1500+ dollars into it before i can drive it as hard and fast as i can my savage..which I've put about 300$ in, and the parts i got for the savage are jsut for more power and better steering. (xtm 24.7, pipe, servo, mp servo saver, diff mod, etc). and even after having replaceded every part for increased durability, NOT for bling factor on the t-maxx...i still dont have that fully confident feeling when i jump it high and dont land right like i do with the savage..and the savage is stock when it comes to chassis/suspension! but this isnt a savage VS t-maxx thread..
from what i have learned in my experiece with the t-maxx in stock form, is that it is built from rather brittle/weak plastic, the tie rods are made from pot metal steel it seems as the stock ones break every time the truck cartwheels..that is if one of the stock plastic rod ends doesn't go first. there are no braces for the suspension control arm pins, putting all the stress on the badly desighnd bulkheads right at the part the pins go thru. the bulks themselves have only two small tabs coming off the chassis about 1/2" to hold them on..jsut not enough contact for a secure hold on a major chassis component. the lower bulkhead is secured to a flimsy plastic "chassis brace" and the plastic skid plate. hey they did throw in a pot metal bulhead cross-member down there though.
the stock shocks will blow out after you get brave with the truck, and seem to get real stiff like the oil inside has solidified, and the caps will break right were the hole for the screw to go thru is.
the body mounts....they cannot handle any roof-style landings whatso-ever...mainly the rear body mounts...the break every time i land on the roof. (comon..everyone does that now and then right)
many people say the driveline is bad..but in my opinon it was desighnd for the
trx 2.5...and i did not break any driveline components while running that mill. the xtm 24.7 that is on there now has basically destroyed anything traxxas in the driveline since then though.
the stock gas tank, i had broken two of them before finally going to an ofna 125cc tank..which sits lower being more proteced on top of giving me a more consistant tune from bottem to top.
TRX 2.5....nice mill when it isnt pissed off at you, makes good power and actually did pull the wheels here and there...and topped the maxx out nicely full clamp. but dayum...thats the hardest to keep well tuned mill I've ever owened....RTR or aftermarket bought. adding a GH cooling head helped..but it jsut did not have enough overall torque/dissplacement to do the work of pushing a monster truck around off-road without heating up to scary temps (355 degrees anyone??)
there are a few other things i do not like..but are mainly opinion and did not effect truck in terms of reliabilty/performance that much, like reverse, easy start.
my t-maxx was my first nitro and r/c..i still like the damn thing...and i have to admit its a freakin beast now in the form its in (basically 95% aftermarket)..it gets my attention more than any of the other nitros..wether thats good or bad i wont say...and even though i seemed to complain about adding so much $$$$ jsut so it can be drivin like i drive my basically stock savage without calling for the medic....i dont regret buying/modding it one bit.
