Bashing is boring to begin with, never seen the attraction with it.

Flex can cause binding and kill the servo it doesn't have to break the servo to destroy it.

Non-the-less Losi seems to have fixed it with a couple easy modifications (o'rings and spacers for flex) and setup. It's not a mystery to them.

RE: Durability of 8ight
 

Call and ask, they make a few excuses and tell you to send the broken servo in. When you ask them to anylize the broken servo, they say it can't be done. If it were flex, then as soon as people started using the metal chassis stiffeners, the problem would stop...it doesn't. THen they came uout with the carbon fiber radio tray stiffiners, adn all they do is move your servo up so high the linkage hits the body. Then the next time you flip the car, or get hit by another in that area, it breaks the servo. Look, I've had my car for the better part of a year, and have been helping others with the same car in all that time. It is NOT flex.

like it says...first run kit

why i asked, is because i'm clueless as to what that means.

shoot me. :D

RE: Durability of 8ight
 

Even the stock chassis isn't going to flex more than 4mm or so (probably even less in this specific area). The servo tray moves more than 4mm when operating it so I highly doubt chassis flex will cause any binding in the linkages.

I have had quite a few JR Z590s and I found them to be very unreliable. For no reason I've had them just lose torque and not quite die or just stop working all together and none of the failures were ever in the 8ight. On the other hand I've heard of some 8ight RTRs working fine even without rubber gromets under the servo. I'm thinking this could have something to do with a bad batch of servos from JR.

I have heard of a few digital servos failing but they have their own problems. If you don't have the EPAs set right or let the servo center perfectly when not in use a digital servo WILL burn out. A lot of digital servos generate a lot of heat which is why some have heat sinks... if a digital servo is strained for to long due to a bad linkage setup it will usually burn out sooner than even an analog servo.

No problems with my 8ight kit yet. It has only had about 3 gallons through it but all of the parts are still factory and fit well.

RE: Durability of 8ight
 

I've called Horizon several times. They no longer act like they don't have a clue. They now tell you to add the O'rings, spacers and rubber grommets to the servos to help relieve the stress on the radio tray caused by flexing. Mine was fixed the minute I installed the kit type chassis. Before that I lost both the JR servos and one Hitec. Some people have no problems from the start, some loose a couple servos and fix it with setup, some have changed carbs and fixed it, other broke servos and then many like myself fixed it by solving chassis flex issues and setup combined.

The fixes Losi came up with didn't have anything to do with linkage binding. The binding is in other areas. Their setup addendum fixed the linkage setup issues.

In the first few setups that were posted on the net one of the important things to do was to leave the throttle servo screws a little loose so it could move. You were also instructed to leave enough room between the battery box and the servo so the two wouldn't hit and bind the servo, a problem caused by chassis flex. The O'rings in the battery box mount solves that issue. The spacers and rubber grommets on the servo mount lifts the servo and solves the binding against the chassis bottom issues plus it allows it to move if it should contact the radio tray, another problem caused by flex. Then there is proper setup and cutting the spring.

One fix by itself doesn't work. Rather than state it is all one thing or the other I would suggest anyone buying a new 8ight, especially the RTR, do all of the things Losi instructs them to do, o'rings, spacers, and setup. I have noticed that since they came out with all of the above the issue seems to be dying. Losi has a clue. ;)

the 8ight is probally the strongest 1/8 scale buggy available from everything ive heard and from personnel experience.

RE: Durability of 8ight
 

The pro kit is pleanty tough but the RTR's chassis, shock towers, and shock caps are pretty weak. I just cased a tripple jump to many times to count today trying to get the line down perfectly but nothing broke even after pleanty of tumbles. I don't think some of the RTR parts would have taken all of what I threw at it today.

RE: Durability of 8ight
 

i run the RTR since it was on sale at the local hobby shop. freaking 500 dollars out the door. lol. but yeah its in pieces right now. i have had 1 servo crack on the first day. my throttle servo is broken right now. I think throttle went out since the servo saver was really tight. but now since the throttle servo has gone out, i think it might be the servos just hitting real hard when i race. just my input.

RE: Durability of 8ight
 

the 8ight is incredibly durable...I have about 3 gallons on it and have broken a couple of tie rod ends only (all running on a track). Even casing a 40 foot quad this past weekend did not do anything to me - I also smacked a rebar post that came out of the pipe at full throttle...I thought sure I was going to have a busted up front end, but nothing was broke...they are some tuff buggies to be sure

RE: Durability of 8ight
 

I recently assembled my 8ight kit I've had awhile, so I'm not sure if its first run or not,

Can you please give me a run-down on the fixes or a link to that RC Tech article mentioned throughout this thread so I can fix mine or check it?

From the discussions on here I'm getting a rough picture of what needs to be done, but a more concise description would be great.

TIA

This is the thread that has ALL the info you will need:

RE: Durability of 8ight
 

thanks for the link.

Its a bit huge at 109 pages. I tried searching for the set-up part that you are speaking of, but it pulls just about every page back...

Do you recall what the fix is and can post it?

RE: Durability of 8ight
 

Mine wasn't set up perfectly either because I never heard of the problem when I built my kit but my servo hasn't crapped out. Still I did do it to be on the safe side.
First, put the rubber grommets that come with your servos on to raise it up a bit and soak up some vibration along with keeping the servo off the chassis.
Next make sure the servo horn is parallel to the servo and not at any angel.
Third, trim the throttle spring a little bit so you can get full braking power without the spring binding up and of course still allowing the throttle to close correctly.
Last, make sure your throttle and brake linkages are as horizontally level as you can get them.
I don't feel all of this is nessisary but it makes for a perfect linkage setup anyway which is always nice.

RE: Durability of 8ight
 

Below is Horizon's throttle setup addendum. That will get it set up right.

That's a fact., It doesn't take much to bend or brake the RTR parts.
