Hey how can i get my t maxx to do wheelies? The suspensions pretty hard and i have a wheelie bar but the thing just wont pull up. Its a 2.5 and its broken in properlly. Maybe the Slipper Clutch is too loose?

bigger spur gear or smaller clutch bell should do it...

Assuming that it's tuned properly of course...

you shouldn't have to change gearing to pull wheelies. a good tune will do it. i used to pull wheelies with my 2.5 on stock tires on pavement. just play with the tune and slipper setting, you'll get it.

ya...just keep tuning it untill you start seeing the frnt wheels come up...trust me and everyone on here...its a pain to test and tune these engines...but at the end...its worth it!!! when i was breaking in my 3.3...by the 4-6 tank...i was busting wheelies up and down my street!!!

so be patient...test and tune to your weather and temp...and in no time...youll be busting wheelies all day!!!!!

have fun!

Tune until there is a thick plume of blue smoke and then lean both high and low needles 1/8th turn at a time until it pops up. The front end should be popping up, when i had my 2.5 i could pop it up as it shifted into second if i hit a decent bump. Also what brand fuel and what percent are you using?

I had the 2.5r in my T-Maxx, but it never wheelied...tightening the slipper, having good traction, and possibly a diff gear ratio could help but idk

Do not lean both needles at the same time.  Follow the tuning instructions given all over these forums.  Tune for sound/smoke/performance first, this will be done with the HSN.  Set the LSN at stock settings, then lean 1/12th of a turn while you tune the HSN.  After you get the smoke/sound/performance right, tune the LSN using the pinch test (my preferred method) or the idle test (not as exact).  Just make sure after each and every adjustment you make, you do a couple high speed runs to clean excess fuel out of the carb.  Once it's tuned right, it will idle for a long time and wheelie on command.  My S-Maxx idles forever, never overheats, wheelies on command and runs like a bat outta heck with the 2.5.  Once you get a good tune, you will only need to make minor adjustments (usually just 1/8 turn lean (hotter weather) or rich (colder weather)on the HSN) whenever you bring it out after that.  You will pretty much be able to leave the LSN alone until the outside temperature changes dramatically.

Yes check your tune. How much fuel have you ran through it? Check drive shafts for twisting at the sliding connection, especially the rear shafts, mine did this and NOWHEELY any more, replace drive shafts. Also try a new glow plug and don't use stale fuel. If no wheely check tranny input gear pin I sheared mine off fr wheelys 3 times, over drill hole and gear slightly and insert a drive shaft pin much stronger.

First thing that jumps out at me is once you set your Low Speed Needle, You don't want to adjust it again. With any Nitro enine you tune the High Speed first then the Low Speed. Once those are set you only need to set the High Speed from day to day as the weather changes.
When I wanted my Tmaxx with the 2.5 in it to wheelie I changed the gearing. The tranny was a single speed FOC but it ran very good. It's hard to desrcibe how to make a Nitro Truck wheelie. I've owned 4 Nitro Trucks and all of them were able to wheelie almost on demand. And all 4 Nitro Trucks had diferent Engine's. TRX 2.5, TRX3.3, O.S. .21RG and My current Losi XXL has a .28.
If your still having trouble and it gets frustrating, go buy a Nitro Truck with a bigger Engine. The bigger they are he easier they are to tune. Good Luck!

All the T-Maxxes around here can pull wheelies with a 2.5.  It just has to be tuned right.  My Bro-in-law got a T-Maxx with a 2.5 in a trade.  When I got done tuning it, it pulls wheelies, hauls azz, stays right around 250 degrees and has held the tune very well, requiring only a 1/12th to 1/8th of a turn on the HSN to account for outside temp/humidity changes.  Three of my buddies run Maxxes, one with the 2.5, one with the 2.5R and one with a 3.3.  All wheelie on demand.

this was my first new out of the box nitro all the other used ones ive had were used so im still getting used to tuning how long did it take you to tune your inlaws

I've been in Nitro for over 8 years now.  It took me about 3 minutes to get it good, then some fine adjusting over the next 10 minutes to get it perfect.  You should be able to get to a good tune with only a few high speed passes.  Then you have to adjust in very small increments to get it perfect.  His truck will sit and idle forever, then pull a wheelie as soon as he punches the throttle.  The only thing I can't get him to do is get rid of his temp gun.  I thought I had taught him how to tune his trucks when I tuned the T-Maxx, but he chases temps on his Firestorm all day while he's running.  He's constantly having to change glow plugs due to bad tunes.  His engine will be shot soon.  Don't chase temps!  After a long hard run the engine will be hotter.  On hot days the engine will be really hot after a long run, don't be alarmed if it goes over 285 after a long run on a 100 degree day.  As long as there is a good smoke trail, the sound is right and it runs without cutting out, you know you have a good tune.

I disagree. On some engines (GRP, RB, etc) you want to tune the LSN first, and I tune the LSN first on ALL my engines. Read my tunng guide here, <a href="http://www.rcuniverse.com/forum/m_8831801/anchors_8831801/mpage_1/key_/anchor/tm.htm#8831801">
http://www.rcuniverse.com/forum/m_8831801/anchors_8831801/mpage_1/key_/anchor/tm.htm#8831801</a> . It goes against all other methods, but this is what the pros do to tune and it works phenomial!

Right, are we gonna make this guy a pro right off the bat? We're talking about newbies to the Nitro scene. He's got13 posts which tells me he's gonna need lots offeedback.Let's start with basics first then go from there. People can learn as they go. I wasn't asking you if you agreed or not I was just stating what works for me. To each their own.
How can you tell or teach someone who's new to go against the method? I guess I'll stick to the Losi Forum and leave you guys to your own.</p>

Wheelies are a function of tuning with the T-Maxx... Here is a short video of my 2.5 converted to 3.3 specs running an OS 18 TM... The OS has plenty of power, but not that much more than the 2.5 or 3.3... If the OS is slightly off tune, it won't wheelie either... Enjoy

would a smaller spur gear make it more responsive , or say more low end ? Noob hear .
