Pm back. Leaving the office for the afternoon. I left you my cell. Call me when you get a minute.

Can someone take a straight edge to the bottom of their truck from front to back and see what the kind of a gap you have from the center of the chassis to the straight edge?

I've gotta figure this out. Its driving nuts and breaking the wallet.:lol:

Disagree. 7940 is an awesome throttle servo. If you set it up properly it will last a long time, even in a losi car. Mine have been running perfect for well over a year now.;)

Split diff mount can only help you in this situation. It really helps to have as straight of a shot as you can. Your angles look alright, but they could be better. I'd also like to see you rotate the throttle ball on the engine down a bit. Should help straighten the pull through the whole arc a bit better. See as the horn rotates on throttle the linkage mount moves toward the front of the truck a bit as well. Having the throttle ball a bit more forward will help it stay straight when the horn rotates.;)

It is pretty normal to have a little bend in your chassis. I've gotten them right from the factory that way. I don't think your problem lies with the chassis, but in the way you've been mounting your servos. Hitec servos require a spacer in the throttle position of the losi cars. I would definitely put some in there before running any more. It also may be wise to replace the radio tray. If the chassis is worn other than the slight arc, it may be time for a new one.

I would also get some heat into that engine and make sure you don't have a slight bind that only shows up when at running temp.;)

just checked mine for you, and there is just enough room to slide a peice of paper under.

40's are NOT the issue.


there is Such thing as a Tweeked chassis, BUT the Losi's Do Come from the factory with a bow in them, As ive said. its 100% Normal.


;)





dnebout, Your having some strange issues. As other have said, Something is up as 4 Hitec's failing in a row as you have done is VERY abnormal. We'll get you sorted sooner or later.

IMo the Split center diff is Not a Needed item.

On a side note, Its GREAT to be back home after a LONG 2 weeks in Arizona. Thx again to all the guys who made thing's possible. ( You know who you are ) :)

+1 You did not have the center split diff mount before and your servo was fine for a while. Something else is going on, you just have to chase the problem down. If Hi-tech is saying your chassis is slapping the servo; just try and space your servo a little higher.

Took a couple pics of my linkage setup for you. Notice how it is actually a bit angled towards the center diff at neutral and how at full throttle it is almost perfectly straight. Sorry about the dirty truck.:lol:

:eek::eek::eek:...i need the split center diff mount bad!:lol::nod:

I run the carbon radio tray stiffener, I've run one ever since the 1.0 and I've never had any servo problems..yes I know that in the photo the screw for the horn is not on..old photo..I was still setting the end points..;)

is there a specific reason for mounting the transponder under instead of on top by switch??? just wondered, if its so it is closer to scoring loop, i have tested ours at the track and registers about 30" above loop witout a problem. just curious is all?

That's a straight pull... Thanks for the pics. Thinking about getting that.

Split diff is not needed just sand some off the stock plastic top. Mine isnt as straight as Jammin's but darn close. :nod: And normally i run the transponder low but have it Velcro-ed uptop so i could swap it out for my SCT class quick. But a buddy of mine is lending me one so down under it will go again. looks cleaner down there. :D

I don't have one yet. I was just saying that it could be a solution to my problem. I think you're right about raising the servo a bit. For a year now, I've been using just rubber grommets. I may add some spacers someone gave me.

Yeah good point. I can see where you were going with your earlier post with the ball angle on my truck and how that can affect the angle of the pull.

I'll also try it with the engine all warmed up an toasty.
