Yes....its set to the max which is 125 on both left and right, and using a JR 8711 servo.

Ok...Dave found the problem. Checked 2 2.0's and both were the same problem. The steering arm per the manual is suppose to be 73.70mm long. Mine was 78.77mm and my buddy's was 77.20mm. Both of us were using the trim way off to adjust to get straight, but mine was way more and the arm was so long is was not allowing full lock one way.. Also after doing this the steering trim on mine is now only 2 and lock to lock no problem. So this needs to be mentioned. Also the servo arm now sits completely straight in the middle.... :party:. I am now ready for my race this weekend. First truggy race ever for me.....been racing MT class this year so far. So new experience.

Race Report
 
Got an update. I raced at my "local" track this weekend. It was opening day and the first of many races there for the 2009 season. It was also my first full race day on the new 8T 2.0 Electric.

Overall it went great. The truck ran strong and fast in each of the two qualify rounds and it survived it's first full 10 minute main. The field included about 3 other 8T 2.0's (all nitro) as well as two new Z01-T's and a few other quality race trucks. I think there were 7 in the A Main after the B main winner bumped up.

In Practice I roasted yet another servo. This was AFTER I replaced the spring with the 1.0 spring. About the only thing I don't know is if the servo was a little wounded before I put it in. I know the spring was set about 1/2 up the post so when I swapped it out I moved it way down.

Qualifying was painless. I won my first round, not sure about the second. I ended up qualifying 3rd. TQ was held by Kevin H from RCCA, he was running a sweet 8T 2.0 which will be featured in a soon to be released RCCA mag. Props to him for laying down a smoking qualify time.

The start of the main was a disaster, I got butt-slammed going up the "wall" and ended up in last place. I decided to take my mandatory pit on the first lap b/c you can't do much worse than last. After that I mounted my charge and I will say, the 8T 2.0 likes to be pushed. I was picking them off, I quickly worked my way back up to 3rd. Somehow I managed to get around Kevin into 2nd and started my charge for the win. With about 2 minutes to go the shock end broke and I pretty much lost the ability to turn left. I hung in there, drove erratically in order to make those lefts but somehow I managed to hang on to second. (In all fairness, the guy in 3rd stalled out on the last lap.) I feel pretty confident that had I not been running on 3 shocks, I would have caught the leader.

Oddly enough this shock end had already been replaced. It didn't fall off like many of the original one's have done, this one broke at the eye hole. Cracked right in half through the plastic. Very unusual. Anyway it was a quick and cheap fix so I'm all set for this coming weekend. Here are some photos from the day:

Our track has some real air now...here is a photo from the "big double" jump:

We also have a new corner called "The wall" in this photo my truck is humping another truck...
http://visionarycomputer.net/rc/8ightT2e/wall.jpg

Another decent size jump is the stepdown triple:

Finally one of the 8T 2.0's strong points, corner exit is always quick...

I hope to get some video next week.

jzemaxx 05.05.2009 08:24 PM

Dave awesome results and awesome pics!! I myself raced this weekend as well with the 2.0. Swept all the qualifying heats as TQ then also won the main. The 2.0 is awesome and does like to be driven deep into the turns as opposed to the RC8T which I also drove in the 2nd heat. Can't wait for the next race, I plan to do some changes and try to get some better lap times. The truck was within .7ths off the track record on the first time out. I am truely happy!

Kcaz25 05.05.2009 09:01 PM

That track is sick!! I'm jealous!

Sower 05.07.2009 02:24 PM

With the shock end issue - why not try one from another MFR like Xray or Mugen? Won't they fit on the rod ends of the Losi shocks?

Electric Dave 05.07.2009 10:19 PM

The one I had replaced was something I picked up from a guy at the track, it was a Losi but one for the 1.0 truggy. I don't think it's failure is indicative of anything wrong with the design, I do think I'll pick up some 2.0 ends and likely never have the issue again. But I would also consider others if there seems to be a recurring problem.

e-mikey 05.08.2009 08:48 AM

Dave, Losi sent me v1 shock ends as a replacement, not 2.0 ones.

They did the same thing for me... The told me only to use the shock ends, the tech said the spring retainers are different.. I used one of them and haven't noticed an difference..

entjoles 05.08.2009 09:41 PM

wow that track looks cool

Electric Dave 05.09.2009 09:50 PM

Miserable day at the track today. Two more servos. About the only good news is that I met a guy who told me it's not the spring, it's the plastic. There is something about the plastic which causes the saver to bind regardless of the spring tension. He had a "fixed" one which was filed down a bit. I have a very pissed off call into Losi.

Before the servo hell I had one good qual round and really stepped up my time from the week before. I was 0.07 seconds from 13 laps! Only Kevin H from RCCA has turned 13 on the track in any class. It was mine and one small blip more and I would have had it. Then Qual 2 servo and main servo.

So many issues with this darn truck. Losi should release a service pack...

nitrostarter 05.10.2009 11:05 AM

Make sure Losi knows about you having replaced multiple servo's already. They may offer compensation for the hardship experienced....

Looks good tho!

Dave I will join you on this as well. 1 servo already down for me as well. Stripped it....luckily I use JR's so warranty is good. But getting tired of swapping out parts. Also the shock rod ends for me have been a pain. All 4 have now been replaced. One at a time they would strip off. :whip:

Electric Dave 05.17.2009 06:49 PM

What a difference a week makes!

I did speak with Losi, it was an OK conversation. "Bill" was willing to send me replacement parts for just about whatever I said had broken. We spoke about the servo saver and he said the 2.0 plastics were "hard on servos" and suggested that I switch to the 1.0 plastic (which I had already ordered). We will see if Losi does actually come through with the parts they promised but I did get the 1.0 plastics on my own and popped them in. Losi was not willing/able to help me out with the servo gears but I plan to take that up with JR.

Raced yesterday and I think it was my first full day without a single incident on the 8T 2.0. Ran like a bear and kept running. Won Q1, won Q2 and Won the Main! Perfect race day.

Next week the track is closed so in two weeks I'll be back with new rubber and a little bit heavier shock oils. Been running the stock tires which are OK but I've got some brand new AKAs to try out. I figured if I could race well on the stockers, some real race rubber should only make it easier.

That's great to hear - nice work!! So did you just replace the servo saver arm with the 1.0 or the whole assembly?

I went whole hog. I replaced both sides with the 1.0 plastic and I even used the 1.0 "tube" spring and nut. The truck did not handle any differently. Whatever the difference, it's minor.

Electric Dave 05.24.2009 07:36 PM

Minor update, our local track was closed this weekend for the holiday so I did my first major once over on the Truggy (and buggy) I noticed something which I should have seen a long time ago, the small plastic top which goes on the center diff rubs on both the truggy and buggy, against the plastic spur. The plastic spur has already caused problems for many people because it also rubs against the diff mount itself but the rubbing against the diff top part is an easy fix. I could see where it was rubbing and I just took a sanding wheel on my dremmel and sanded it right off. Not sure how much of a difference it will make now (because the friction had pretty much already did the job) but every little bit helps - and I know if I ever need a new one of those, I'll need to grind them down before I use them. I should have taken a photo but I was too focused on the wrenching.

SERVO SAVER problem
 
Hello,
Wanted to give you some insight to what the servo problem is. The servo saver spring that it included with the 8ight 2.0 is too large. The coils of the spring are almost touching each other already and this does not allow the spring to compress well. The fix is to simply buy the fiorini spring that A Main carrys. This is a upgrade part and you may need to look for it in the 1.0 section. It will work on the the 2.0. Smaller spring gauge and the coils are further apart, allowing the spring to actually work.

himalaya 05.27.2009 01:25 AM

Good point Rob, my buddy was complaining about keep losing his 2.0's servo arm teeth. Thanks for the note.

Thanks for your post. I know that lots of guys on other forums have had success with just a spring change but for me, I swapped out the spring very early and still was blowing servo gears like crazy. I'm 100% sure that my 2.0 plastics were molded wrong. I've got the 1.0 plastics (and spring) now and it seems to be working so I'm staying with this setup. My advice to everyone would be to make sure your assembly can actuate when you take it out to install the other spring. If it binds or is impossible to actuate, get new plastics to go along with the spring and it will all work our fine.

jzemaxx 06.23.2009 12:35 PM

Dave are you still having issues with on-power push?? Seems mine likes to push through the turns on power. I am still running the stock springs though so that maybe a problem. I see you switched to the stiffer purple springs in the rear. Did it help with the rotation of the truck?

Electric Dave 06.25.2009 01:42 PM

I'm happy with the handling now. I went to stiffer rear springs, heavier oils in the front and rear shocks and 30K in the center. 3 degree toe block from KH. Now it's just getting used to how it handles but I like it...also ditched the stock tires, AKA rules. I bought I-Beams but I tried a friends CityBlocks and liked them much better.

Kcaz25 06.25.2009 01:46 PM

How does your Xcelorin combo compare to your MMM Neu setups?

I am running the city's and ibeams as well. I use the ibeams up front and city's in the back for the tracks that are tight where I need a little rotation. Also city in the fronts and ibeams rears work well on loose conditions. The stock tires are great for clay and hot conditions....they seem to bite good there, but other then that, not a big fan.

I'm still running 10K in the center with 7 in front and 2 rear. So far I like that setup. You are probably geared for much higher speed then me so a thicker oil does help that. I will be trying the stiffer purples this weekend. Also found out the ride height was screwed up again. Looks like with time the springs sag a good bit.

The Xcelorin is in the 8e 2.0 Buggy. My truggy is my baby and it gets the good stuff. I definitely prefer the MMM/Neu to the Losi system. The Losi is very notchy and wierd. Brake is wierd, slow speed is wierd. I'm pulling it out very soon and ebaying that puppy.

Dave anything new?? I swapped to the purple springs and droop is now 105mm in the front. Makes a nice difference. Going to try the 30K diff in the center like yours and see if I can get some better rotation out of the truck.

Well, this past weekend I finally roasted a plastic spur...I had lots of races on it and I'm very pleased with how it held up. I replaced it with a new Losi plastic. Luckily it roasted in Q2, I lost the TQ spot but won the 12 min A Main.

I had one of my Neu motors go, or at least I think it went, I mailed it to Neu after it got over 200 degrees and unsoldered a wire. The backup motor is doing just fine.

Loving AKA Cityblocks.

Our points series starts this coming Saturday....

Jarvis 09.23.2009 11:16 AM

Dave, any changes on the losi? How is everything holding up?

jacobsjo87 09.23.2009 04:29 PM

Did you have any issue with the radio tray? I have the same set up and when I went to bolt the radio tray in the loop that goes around the servo was contacting the front center shaft. It is because the center diff is raised a slight amount from the conversion. I'm just curious if you had the same problem.

It's been doing really well. At my local track we had a new guy start coming. At first he was running a Nitro MBX-6T and then a Nitro 8T 2.0. In any case this guy was really next level, beating me week after week. So I had to step up my game and I've won the A Main the last three races in a row! My lap times are better and the truck is running SO well. I'm really impressed. This past weekend we had 10 trucks in the A and there were about 4 guys from another local track - all of which were capable racers.

I'm quite impressed the truck holds up to the amount of abuse I dish out. I still find that the Losi requires a fair amount of regular maintenance. I've upgraded the hubs front and rear to aluminum. I change the wheel bearings regularly. I've rebuilt the center diff a few times, replacing bearings when I do. Knock on wood, F & R diffs have not been touched!

Here are the standings from our points series, which ends this weekend!

Yep, I had the same issue. After the first run I hit it with the dremmel and it no longer rubs.

Curious that he went from a MBX6-T to a 2.0. Wonder why....seems alot are going from the 2.0 to the MBX6-T. I even thought about trying one, but the ones that have driven both prefer the 2.0....so I guess it depends on driving style. Glad you got the setup dialed in. Still running the Ibeams?

I've considered the same. I keep hearing about the Mugen quality and how durable they are...all things which make for a good E-Conversion. However at our local track, 2 fast guys have switched from MBX6-T's over to 8T 2.0's. Both say it is a positive change. I've not had a chance to drive the Mugen so I can't say how they differ.

For tires I'm running City Blocks. Been very happy with them. The I-Beams are a little more grabby and unpredictable. I feel like I can slide with the City Blocks better and recently my driving style has been a little more on the edge so the CBs are less erratic. I just picked up a set of Calibers, I'll try them soon (but not this weekend, going to close out the series with my truck as is...)

Jarvis 09.25.2009 11:49 AM

Thanks for the Update! I am in one of those Mugen or losi debates right now. I might have to make some laps with jzemaxx's 8t 2.0 and find somebody with a MBX6-T and try it.

I have more of an off power steering need, and I tried the point-and-shoot and power sliding and it didn't work for me. I want a car to round the corner fast and controllable and full throttle after the apex.

PBO 09.25.2009 04:02 PM

Good luck for the series close Dave...keep the updates coming

Electric Dave 09.27.2009 07:49 PM

Had a really great day of racing yesterday. Our own leader, RC Monster Mike decided to come race with us. He brought along Walter (who many of you guys may know). Monster Mike had just completed an O'Donnell Z01-T Electric conversion for the track owner and he was showing off a simply amazing looking MBX6-T Conversion. He was running his older truck however, the Mugen is being shown at iHobby so it stayed off the dirt. In any case, I was lucky enough to lay down a smoking fast first qual round and TQ'd. Mike won the second qual round but in the main I got out front early and checked out, lead from tone to tone! While he wasn't in our Points Series, I wouldn't have felt much like a champion if I got beat in the last race so it was a nice way to end the series. Here are the results:

http://visionarycomputer.net/rc/09PS/week7.pdf

Oh, and to give him and Walter props, they did both beat me in the buggy class...Mike 1st, Walter 2nd and I took 3rd...but as you can tell from this thread, my baby is the Truggy and I needed to avenge my 2nd place finish at the RC Monster bash this year. I fell much better now...

brushlessboy16 09.27.2009 09:15 PM
