When it comes to Nitro Monster trucks Losi has always moved to the beat of a different drummer. When other monsters were using multiple small diameter shocks on each wheel, the original LST defied conventional wisdom by using one massive shock per wheel. When other monster trucks were using a single steering servo, Losi raised the stakes again by utilizing dual-metal geared servos. When others were relying on small block engines, Losi yet again broke the mold by going with a big block. Needless to say the previous Losi monsters' success speaks for itself.

The latest generation of Losi monster is here in the Losi LST XXL. It gains its XXL moniker by being the largest LST to date, but there's more under the body than just a stretched chassis. Featuring refined molded components that are based off the 8IGHT 2.0 Race Roller, a bigger 454-sized engine, optimized transmission and more, the LST XXL is one big and bad truck. Add in Spektrum's telemetry-equipped DX3S transmitter into the mix and you have what is sure to be a winner. It's time to roost the competition and we invite you to come along to see exactly what Losi's latest LST brings to the party. I took out with the LST XXL. I thought it might sound better without it.

Final Thoughts Anyone who has followed our articles on the site know that I spent a good amount of time about two years ago building up what I then called the "Ultimate Race LST2". That truck was tweaked for performance and durability with bashing as an afterthought. I ran more than a few gallons of fuel through that truck but honestly haven't driven a nitro monster truck in some time. I went over the truck before break-in to make sure everything was tightened up properly, gave the shocks the "squish test", checked the telemetry installation out and more. Score one for the LST XXL as it passed my bench test with flying colors. The LST XXL comes with a combination pull start/spin start backplate. Now anyone can start a big block with a spin starter but the real test comes when you need to pull start it. Foregoing the spin start in favor of pull starting I was pleasantly surprised when the engine came to life after just a few pulls. After a minute or two of warm-up I pulled the glow driver and was impressed as it just sat there and idled perfectly. After the engine was broken in I took the truck to the dirt to let the LST XXL eat. Power, power, and more power is what you get with the LST XXL. As you can see from the video it has the bottom end torque to get up and over a wide variety of obstacles. In fact it seemed like the LST XXL was better able to climb the hills than I was! As impressive as its climbing prowess was, I was just as impressed with its precise control I had each and every time I descended the mound. The brakes slowed my descent while not being overly grabby or touchy. The suspension was absolutely perfect in these conditions as well and, owing to its being directly lifted from the LST2, I had very high expectations for the suspension and it didn't disappoint. Perhaps the neatest aspect of the LST XXL was in fact the built-in telemetry. I never had to stop running to see what the head temps were!Monitoring the temperatures was as simple as just looking at the DX3S' large display screen and there it was. For all the abuse I put the truck through the engine never got above 240-degrees, even in the high humidity and 85-degree temperatures. To say I was impressed with the LST XXL! would be an understatement. I tried to break this truck, I really did, but it just came back looking for more each and every time I flipped it, rolled it or sent it careening. The straight-line speed was awesome, but I was more impressed by the torque and control offered by this truck. This is indeed a worthy successor to the LST2 in every possible way that still gives me a reason to pause and smile as I sit here typing, thinking back to everything I put this truck through. This is what RC fun is supposed to be about, and the LST XXL nails it! Offroad

I need help Anyone. The Engine has just siezed up, cant spin the motor. HELP ME SOMEONE

[RoyalsChamp5]

Thank you all for your help, i will try tuning to what you all say, the next time i bring it out!

[joel123lol]

get a another engine

[iamthanatos]

@RoyalsChamp5 youll have to take the engine out open up the gasket, glow plug and rear plate, and drown it in WD40 keep rocking the fly wheel back and forth until it loosens out you might have cooked the engine running it so lean...

[starfiredragons]

Im running my Losi on Medium Odonnell Plug with LSN 3 turns out and high 2 1/2 turns out and getting great jump off the line and 52 top end mph in this cold ass weather...

[iamcyberpunk68]

run a hot plug for starters , do a pinch test to get the lsn setting correct and the hs ,,i would start at 3 turns out from bottom . when you pinch the fuel line at the carb,,,it should run for 4 seconds then slightly climb in rpm ,,say 200 then die , if it keeps running longer then that ,bottom is too rich . if it dies sooner then 4 sec ,,then to lean.

[rroberts383]

these guys sound about what i would tell you, but running rich i have found can ruin your glow plug. go buy a new hot or medium hot plug, made mine run a million times better. just check your head temps and make sure you dont get too lean. water should evap fast off head, but not boil. good luck!

@IbzSolja1 Defenitly seems like it's to rich, all that smoke coming from the exhaust while its at idle. Try turning high speed neddle clock wise to lean it, only 1/4 turns at a time to run that extra fuel out of it. It will take a few times.

[traxxasslash26]

im not a nitro guy, but it seems like your running too rich, causing the motor to consume more fuel, which doesnt have a good combo or the air and fuel causing it to shut off.. ?

[hypercriticalone]

Check low and high needles, also make sure you are running the right percentage fuel, probably 25%, 16% may work
