![]() ![]() ![]() The TRX 3.3 Racing Engine is so powerful it establishes a whole new classification of power. It embodies everything we've learned from decades of making engines more powerful, more reliable, and easier to use. Then came the TRX 2.5, a marvel of award-winning power and technology that set the bar for Ready-To-Race © performance to unimaginable new heights.įast forward to the present and years of nitro engine development have culminated into the most powerful TRX engine ever made, the TRX 3.3 Racing Engine. EZ-Start later evolved to incorporate built-in diagnostic functions, LED indicators, a constant-voltage glow plug circuit, and more powerful starter motors. Next, the Traxxas EZ-Start © system ushered in a new era of convenience and ease of use with true, push-button electric starting. Traxxas has always been at the forefront of innovation, beginning with the powerful and reliable TRX ¶©¶ÿPro.15. The TRX 3.3 Racing Engine draws from a legacy of precision Traxxas engine design and manufacturing. ![]() This includes listening to our customers, and developing the highest standards and conventions that would meet the performance challenge. Traxxas engineers are dedicated to redefining the state of the art in engine technology. Traxxas TRX © Racing Engines are fueled by a passion for performance, innovation and quality. If you think its too lean richen it out and then try again but lsn tuning is a pain, its more sensative so do a few runs by slow then fast slow then fast then re check your setting.Revo 3.3 powered by stock TRX © 3.3 Racing EngineĮight-Time Winner: RC Pro Series 2004-2009, ROAR 2006-2007 I have my lsn at 1.75 and it looks happy enough with that, not gobbing fuel out everywhere and just a reasonable ammount of smoke but I noticed Byron doesnt smoke as much so its only a guide. Once your happy with the top speed check the lsn by doing the pinch test if you can be bothered lol. could be a little boggy but hsn is prettymuch factory settings on it so I'd honestly say start at 5 turns out on your hsn and 1.75 on your lsn and play, warm up then a few high speed runs to see if your hitting max speed, also check sound of engine, on if its bogging with too much fuel or slowing and missing due to being too lean, then check temp, if its running too hot richen it up an 1/8 then try again a couple of runs then re check. His lsn is rather rich but wont hurt anything I guess. Think the kids drank far too much coke in that vid but You have to use all tuning guides as a base as nitro engines are effected by ambient temp and humidity. its easyerr for me this way as long as its not massive tweeking. Keep to 1.5 1.75 turns and tweek the idle with the trim. and then once your happy sort out the tick over tehn if you really need to do the lsn but if you do this will affect the tick over. Keep playing, and if your still having issues, reset the needles and start again rather than trying to get it from where you are.Ī few high speed runs then check the temp. I honestly have to agree with revo rocks on the lsn, I think if you want it to set off like a loon then ok, lean it out but if its lean when you kill the throttle it will still be lean on over run therefor wont slow as quick or cool as quick. It runs cooler without a body so I'm building a cage soon that will look the muts and also keep it cool. I'm still experimenting but I've found that they run hot anyway, and if you can keep it around 270 your doing well with a stock body. ![]() toi lean and its hits second quickly but will heat up. I think its stock gearbox so I tune it so its enough to hit second gear without a massive run up and thats it. I now run Byron 25% and I get high temps but with my temp gun I keep an eye out. I have gone through 1/2 a gallong of duraglow 16 and 25% wich in all honesty is carp as it just globs gunk everywhere and runs hot as it canty burn half the oil its putting in. They come with 4 turns out but I wound mine to 5 turns on the hsn and 1 3/4 turns LSN and I'm still on the same plug as when I started. ![]()
