Still loving it! Review by TheCanuck
Review update, by TheCanuck (in Arizona) — Posted May 8, 2013
After nearly 5 months, this buggy still Kicks A$$!
6 months ago, I was a nitro newb, when I began assembling 3 nitro R/C projects almost simultaneously.
All three projects involved building close to stock vehicles. The three nitro builds were an XTM Rail, a Traxxas Revo 3.3, and a Losi Ten-T.
Although I began working on my XTM Nitro Rail first, I actually completed my entirely stock Traxxas Revo 3.3 before the other two.
The delay on completing the Rail was mostly due to the difficulty completing the build's tuned pipe. After unsuccessfully trying 5 or 6 different buggy pipes, All of which were pretty standard, I had to abandon the idea of starting off with an upgraded pipe because none of the headers would clear the geometry of the Rail's chassis. Then, after deciding to revert to the stock pipe, parts availability kept me from completing the project for a while.
Ultimately, I ended up with a stock pipe, and it seems just fine.
After having completed all three builds, and enjoying all of them, I must conclude that I prefer my XTM Nitro Rail over the other two.
It is more durable, and more reliable than my Revo, and my Ten-T. I spend more time driving it, than wrenching on it, compared to the other two.
After getting some fuel through all three vehicles, my Revo is currently down with a cooked TRX3.3 engine, and my Ten-T has a broken rear shock tower.
The powered starters on my Revo and Ten-T have given me many headaches. In both cases, the batteries seem way underpowered, and run out, preventing me from being able to start either vehicle.
On my Ten-T, the underpowered battery was the cause of a runaway—straight into a brick wall, costing many $ to repair it. To this day, I can run my Ten-T only two times before I need to recharge it's 1000mAh battery. Losi recommends to NOT replace the stock battery with an aftermarket one, due to proprietary protection circuitry they have loaded onto their underpowered Lipo.
My Revo 3.3 was a nightmare to get started, initially, as was breaking in the engine. I tried to follow the manual to a "T", but it took WAY longer to break-in than Traxxas stated it would. A major problem in this was the crappy, underpowered Nimh battery. It would hardly hold any charge, and would quickly run out, stopping my ability to start the engine, and continue breaking it in. After hitting it with a forming charge on my fancy charger, and cycling it with discharge/charge cycles about 5 times, did the Nimh battery finally work well enough to start my Revo.
About a month after getting my Revo going, the TRX3.3 power plant quit, while I was bashing in some fallen leaves on the lawn behind my house. I thought it just ran out of fuel, but later discovered the push rod split down the middle, and broke pieces off of the bottom edge of the piston. I've since learned TRX3.3's don't hold engine tunes well, and are notorious for this type of failure. I have attempted to repair this vehicle with an SH .21 engine, but due to the incompatibilities causing hassles and a rising cost, I have abandoned that idea. I now want to try to fix it with an Ofna Picco .26 engine that is designed to be dropped in to a Revo. Time will tell how this goes.
My XTM Nitro Rail keeps going, and going, and going...
Sure, it was hard to start with the pullstart, at first. But, once a bunch of tanks had gone through it, and I learned lots of technique and tricks from the local nitro experts, it now starts on the first or second pull, after priming the engine.
I NEVER HAVE TO WORRY ABOUT THE STARTER BATTERY RUNNING OUT, because there isn't one.
The engine is holding it's tune wonderfully. I can get two or three nights worth of racing in before I need to recharge my upgraded Hyperion LiFePo4 receiver pack.
I've broken two of the stock wheels, because I forgot to replace them with my dish wheels one time when I started jumping. Other times, a couple steering servo parts broke, as well as my stock wing. BUT THAT'S IT!
One more negative I will add though, is the model memory feature of the Airtronics radio does not save all settings between the stored models, and the model selection process is poor, especially when compared to the Traxxas TQi system.
If Traxxas would add antilock braking to their TQi system, I would drop this Airtronics radio in a moment. Even without ABS, I may drop this Airtronics radio in favor of the TQi anyways.
If you are considering this buggy, I highly doubt you will be disappointed.

Love it, love it, love it! Review by TheCanuck
This buggy is awesome!
I already have two brushless XTM Rail's, so I already knew the quality and durability were going to be top notch.
These buggies are well designed, and well built. Built to take abuse, and last.
On these nitro versions, the ABS system in the Airtronics radio is the bomb. I was often locking up the wheels and going into slides, but no more after turning on the ABS.
The XTM manuals are among the best in the industry too, especially the downloadable PDF's. You know those cheaply made cars with the crummy manuals? The one's with blurry bitmap graphics that only get more pixelated when you try to zoom in for better detail? Well, these manuals are not like that at all! The graphics are stroked so you can really zoom-in and clearly see the detail you need.
The buggy is a pleasure to work on. Easy access to most areas, and lifting the cage up is very cool. It is easily upgradeable, and compatible with many aftermarket parts. I put in a Hyperion LiFePo4 receiver pack, and a 23Kg Airtronics all metal gear steering servo. I also like the extra protection provided by the 3rd party T-Bone Racing bumper hopups.
At my local track, all the guys are very interested in it, and I hear comments like "That's the best looking buggy ever!". I'm whipping around the track like a Banshee, and most of the time I'm barely giving it 1/4 throttle.
If, for some reason, you want this buggy to be brushless, no problem! Most of the components are identical between the brushless and nitro versions, so all you need to do is pull the nitro parts and put in the brushless parts. Just get both manuals open, and start comparing them, making a list of what you need to convert. Converting from brushless to nitro can be done in an identical fashion too.
Now, for the CONS, because let's face it, is anything truly perfect?
The stock six-shot wheels are very cool looking, but are meant for on-road and gentle off-road driving. This is because the center hubs cannot take the abuse from jumping and rough off-road conditions; the centers WILL break. Sure, you can use them to jump off curbs, but not much more. Get yourself some standard disk wheels, and you're good to go.
Also, XTM should use hex style screws instead of so many Philips head screws, because the Philips heads strip more often.
