That sounds great! I'm looking forward the the video!

I see you also own a E-revo. How does it compare to an E-revo in handling and driving? I have yet to own a truggy, so Revo's are the closest thing I know of.

Man, sounds like an awesome machine. I am super jealous.... If I could afford it, the 8T would be my dream rig to do a conversion on.

Looking forward to your reviews of it on the track.

after converting a few Revos and building a Losi 8t truggy I have to say I wish I would have started with a truggy, they handle much better and has twice the steering ability a Revo has but the Revo can handle rough terrain better

I FINALLY took it out today! Now I live on a dirt road, the dirt this time of year is actually very much like the racetrack surface. As soon as I dropped the truck down I noticed the servo was reversed - no biggie - a quick change on the radio and it was pointing in the right way. I slowly crept up on the driveway (which is paved) and did a few low speed turns to just work out the diffs and check the turn radius, very impressive. I couldn't wait anylonger. I headed to the dirt road and gunned it. A-freaking-mazing.

During my build I've been checking the weight of the truck and totally ready to run, with battery and cables, everything (except body, my body is out being painted by AXM) it weighs 4290g (9.46 pounds) which sounds heavy but is almost a full pound lighter than my old CRT. With the weight savings and the free drivetrain on the 8T 2.0 the brushless power is just disgusting. It throws the truck around like a rag doll. I did gear up by 1 tooth (14t on my pinion) and the truck was the fastest I've ever driven. The sound was totally different too (and I've been using a plastic spur for years) it just sounded free-er. More like the whistle you hear on a 1/10th truck. I tore up and down the road for a while, roost tails were flying everywhere. Then I started to hit some bumps and driveway lips. Granted, these were not as big as typical track jumps but the truck was just WAY more composed than the CRT over the same obstacles.

It's always hard to judge the performance on a 10-12' wide road vs a narrow track but I'm much more impressed than I thought I'd be. I can't wait to get it on the track and start getting to know the handling characteristics of this truck. I'm sure given the way it accelerates alone it is going to shave several 10th's off my lap times!

I dunno if you have had a losi conversion before, but industrial strength velcro the entire battery tray and the batteries or they will smash through the front of your tray the first time you nose dive a bit.

My race program last year was my E-CRT and my E-Revo. They both had identical power/motor and batteries and on our small local track, they were actually very close in terms of laptimes. The Truggy definitely is quicker and easier to drive but the E-Revo was really a very well handling vehicles. When the track would get rough, the truggy would have a significant edge.

Thanks for the tip. I will no doubt be adding velcro to the tray and packs. I was considering making some kind of adjustable blocker or something but Velcro is the easy fix, used it in the past and I'll be installing it on this one as well.

Use foam too to take up the extra space. The less momentum that battery has on a crash the better.

HD sells the industrial strength velcro that I love to use and it's a standard mod for me on all my Lipo's and trays. It took breaking 2 batteries and 2 MMM's to learn that lesson. Some people say it's not necessary, but to each is there own.

(Long post alert)

I took the truck down to the Pin Shop Hobbies track yesterday to run some practice laps and shake out any issues with the truck or electronics. For those of you that are not familiar with Pin Shop, the track hasn't been touched since last year. One part was pretty mangled by the snowplowing over the winter. At then end of the season last year, the track was pretty well beaten and in desperate need of a rebuild. I expected it to be rough and really just a shake down of the truck, not so much a setup or tuning day. A few guys showed up and did a great job with the raking, the track was super dry and it seemed to have loads of small pebbles and sand on top.

As far as running the truck, it is just psychotically fast. Perhaps too fast for this small track. I'm only up one pinion tooth from my gearing last year but the truck just felt much faster. There is no doubt the Losi is a fast reacting vehicle. The first pack was a little wild as I was getting to know the truck. I was pleased with the steering. I think the feature I was most impressed with was the jumping. The truck just loves to launch. Again, knowing the track is getting a complete rebuild in the next few weeks, I wasn't too concerned about handling, however I would mention that the rear end was much looser than the old CRT. The truck was just sliding all over the place. Eventually I stopped fighting it and just power-slided around the corners, it was impressive looking but very hard to control and in a race, it would be a very risky way around the corners. Once the real dirt is down and the track is built I'll work on bringing that rear end under control.

While it is great to sing the praises of something, you can get all that from the magazines, I'll mention my gripes with the truck/design. My biggest disappointment is with a flaw in Losi's design. This is the first time the Losi Truggy has 0 offset wheels so the geometry and arms are all new. In short, they rub badly unmodified. Luckily I had read about this online. A few days ago I posted in this thread that I ran it outside my house. When I did that I had not made any changes to the truck. True to form, even in the few minutes I ran around my house, I cracked a small part of one of the webbings inside the front wheel. At full lock the webbing inside the wheel will hit something, the steering knuckle or something. Before hitting the track I did the research. I took a sharpie and laid down a heavy line on the webbing, then I spun it by hand. The black ink showed exactly where the rub was on the webbing. Then I hit the dremmel, I didn't have the exact right bit for the job but I did the best I can. I also read about the rim hitting the arm in use and I can see wear from the spot that rubbed. I will also hit that with a dremmel. Apparently one fix is to use the optional Losi +2mm hubs. They won't require the wheels to be modified. Kind of bothers me that Losi, who touts their Engineering prowess all the time, would have made such a huge mistake. I'd bet that anyone running a new truck, without one of the two mods, will crack their wheel after one run. Other than that, another thing I saw online also happened, the camber links backed out in the front and rear. Fix there is copious amounts of locktight and longer screws to get into the nylon of the locknuts. I will be fixing that right away. Only other gripe is that even after just 4 or 5 runs, the rear bearings already feel not right. I have to take them out and clean them but I've read about some King Heads hubs which make use of larger bearings, I have a feeling that upgrade is in my near future.

The teething pains of a new vehicle design are not uncommon and while I sound pretty critical, I just want to help other guys reading to prepare their 8T 2.0's. I am sure this truck is fantastic and I'm positive that it will shave time off my laps. It is a winner for sure but like anything worth doing, you have to put in some time and effort to make it live up to it's potential.

Dave, I am looking around for possibly a 8T, but didn't know this. Glad you posted this....Is their a losi forum for find problems like this??

Also does the truck oversteer badly on most surfaces or just was it that track?

RCTech has a great forum on the truck. That's where I've done most of my reading.

As for oversteer, hard to say. Yesterday was only the second time I've had the truck out and to be honest, neither surface was ideal. I'm sure the handling is something which just needs to be tuned. Once our track is redone, I plan to start making setup changes and get it to be the way I like it.

[onetoo3]

love your 8ight t 2.0e. can i get it as RTR.
as i see losi has the 8ight e 2.0 as a RTR.
or is there a lot of parts to put the 8ight as a truggy

[onetoo3]

or i get a 8ight e 2.0
and what will i need to put it as a truggy?
wheels,shock parts,dogbones......
