trx 3.3

how much horsepower do these engines make? And what are the differences between 2.5 and 2.5R, some online articles say that the only difference is the blue cooling head but traxxas states that 2.5R makes 0.5 horse power more than the original 2.5, how come?

Q1: What does LSN do, does it effects low rpm or low throttle? if i blip the gas ones (from zero to wide-open quickly, then immediately releasing the trigger) is it HSN or LSN? Q2: does HSN affects idle? Q3: the relation between LSN and idle crew, i can affect idle by either leaning the LSN or...

mod or upgrade that improves power and handling were in count as well:)

I'm running a stock revo 3.3 with optimix 16% fuel I'm running my engine relatively rich and a whole bunch of blue smoke is visible during the acceleration, so i assume that everything should be theoretically fine apart from the fact that the temp was at 280f, i tried richening the needles but...

the manual said that the slide valve should be set so that it has a 0.7 - 1.0 mm gap, but that's just kinda unclear for me, i want to know by how many turns out from completely closed (idle set screw) thks

helo;) Q1: how do i know if my nitro engine needs a rebuild? Q2: should i purchase a brand new engine or only the piston and sleeve set (Traxxas for example) thks for the hlp!

First time starting my revo today, but the engine keeps getting stuck as I’m trying to free it up by the flywheel with a screwdriver, but the engine just never wants to start. Plus that the EZ start motor starts smoking, I really dunno what to do😭 I've tried heating up the engine but no work:(

Q1: is it worth purchasing 20 or 25% nitro in Europe when u need a license for it? Q2: I'm running a stock 3,3 engine and wanna know if switching from 20% to 16% really is a night and day difference? Q3: Will fuel with a lower nitro content decreases the life of the engine? Q4: I'm into buying...

Hi let me say thanks in advance. I just bought the truck and was breaking it in when it stalled on the end of the fourth tank. I tried adjusting and had no luck as soon as you give it throttle it stalls. I replaced the plug reset back to factory settings and I can’t maintain it. What I did...

Hi, all. Recently got a near brand new T-Maxx 3.3 after a long hiatus from anything RC. My plan is to build it into a style of a desert racer, so think Baja 1000. I'm gonna get a Beetle body from Proline soon and then plan to get new wheels and tires, just really confused at the different sizes...

Hello. I'm working on my little brothers t maxx 3.3. The clutch shoes were broke. I replaced them and the spring. I put it back together and if I start it and hold it up the tires move when I give it gas but when I set it down to drive it, it revs up but does not move. I've got myself stumped on...

A couple of weeks ago I bought a used 3.3 T-maxx,since then I have never managed to get the engine to run right, I replaced the carb body due to idle jet hole was stripped out thinking that would be the reason that I have had the following issues, idle up/down on its own, WOT without the car...

My wife got me new tires for my b-day. http://www.sweepracingusa.com/Monster-Truck-Terrain-Crusher-Belted-tire-preglued-on-Black-wheel-2pc-set_p_569.html Comparison to traxxas 3.8 geodes with 3.3 tires: This was also my first run with a losi 3.4 carb on my 3.3. I have an OS21TM, but...

Hi I'm the not so proud owner of a tmaxx 3.3. I'm the third owner and have had nothing but trouble, I've sealed and resealed the engine a hundred times and still have oil everywhere its spraying from the flywheel, and the header and plastic back plate from the pull start are covered in it. its...

Ok so I got a traxxas nitro sport. And just bought a trx 3.3 racing engine for it. Now the problem is that the throttle for the .15 and the throttle for the trx 3.3 are different and I would need to convert the throttle control over to the spring one. But I don't know the circumference or...

Hey guys, I'm doin another motor upgrade so I wont be needing this one. It has great compression and a ton of life left, never overheated and always monitored the temps and kept it around 260-270. I am leaving the current flywheel on it as well so you will just need your clutchshoes and...

I have a spare roto start backplate for a Savage and I was wondering if I could put a hex style OWB on the TRX motor to use this roto start backplate on my Slayer Pro? I'm sick of the EZ start and I have a Traxxas roto start backplate on my Revo but they are so hard to find now. I just want to go...

I know I may sound like an idiot.. but wats the average operating temperature on 3.3 or any motors for that matter????
