Default T Maxx 3.3 problems

I have about 1/2 a gallon thru a new 3.3 and i am on my 4th set of center driveshafts. The pins keep egging out. Called Traxxas and they suggested the slipper clutch was too tight, so I loosened. Same prob over and over again. Traxxas has been great sent all the replacements free of charge so far. Just have to wait 3 days each time. LHS do not carry this part yet, and new CVT metal shafts are not going to be avail for a few months.

Then part of my exhaust had melted down and a chunck of plastic fell into my pipe. I run the engine with a temp gun and it has not exceeded 240 yet. What gives with this? Aftermarket pipe not avail till May 06.

Anyone else experienced these problems?

Some how I don't think everyone I talked to about this has abused their engines within 10 or so tanks. Why can't traxxas just own up to its problems. Look at all the probs the 2.5 had with overheating.

The aftermarket pipes that work on a wasp or OS bigblock should work withe the stock setup. Call my boys at Action Hobby for some sugestions and prices. Talk to Allen, Jeff , or the Owner marty. I sugest Allen. He is a 10 year sponsored racer. Tell them Larry sent ya. 215-249-9750

Ummm why not just buy some metal cvds for a revo? Or even a t-maxx all that stuff should be interchangable I think.

Sway away from the Pico motors. Everyone I have known to own one loves it at first untill they need a part, then they end up scraping the engine. If any one has a scrapped engine I will buy for parts.

I can say with out question I have had a hard time with my new t-maxx 3.3 and the muffler melting I have replaced it 2 times now with the stock one and now its melted again and I haven't got a clue as to what else to use or how to stop it I have called traxxas and they said I am running it to rich? my fist one melted before it was even broke in and today I was reading on the forum some were and it said if the top of your piston is brown or black you have cooked it well my piston is kind of a gold color dose that mean I cooked it some how? when the muffler go's it runs around 300-310 with a good muffler it runs around 250-260 and I asked traxxas about the temp and they said as long as it getting good lubrication it doesn't matter how hot it gets I wish traxxas would just say they are having problems with it but then they have to eat a lot of parts I guess

I don't mean this rude but he just spent 400+$ on his t-maxx. I wish i could just buy one r/c car after another. Sorry to hear about this man. Sounds like you are having serious problems. I had the some problems when i first got my 2.5 t-maxx. So I sympathise. I mean even the guy at the LHS counldn't tune mine right after he did someone elses. And again I'm not trying to be rude or offend anyone.

I haven't even gotten through the first tank of break in on my new 3.3 traxxas and I have melted two pipes. Can you pull the stock plastic pipe apart without wrecking it and will that solve the problem if you remove the baffling?

get an OS 18TM a Picco 21maxx or the Picco 26Maxx. DONT BELEIVE the hype about parts. they are availale at www.nitrohouse.com for ALL PICCO engines. now they may be oos (out of stock) for a certain item once in a while, but they should have it instock in less than a week..
