LST2 Steering Servo Question
Had a steering servo go, and since I only have two High Torque Losi servos (supposedly the XXL and 8T 2.0 RTR steering servos) as spares, I went in to change both..
But they don't fit!! Huge battle getting them in there, dremelling crap, breaking the receiver antenna, etc.. and they don't even line up!! ***? I thought these were JR's just like the 590's (thought they were Losi-labeled JR650's..)and assumed they'd drop right in....
Help?...

The steering bellcranks kind of get in the way of the servo install, so I pull the pins and push the bellcranks out of the way. I had to dremel one of the belcranks to clear the servo case on one side, but not much.
I'm surprised yours dont fit. Other than pulling the servo apart, I didnt find it very troubling to get the 645's in.

I finally got them in, but now the servo arm doesn't line up right. These new servos sit higher or something..

Could you snap a picture of the servo horns not lining up? I'm curious as to how your truck is set up with those servos.

RE: LST2 Steering Servo Question
F' it.. Just gonna' pick up another Z590.. Found two on a local forum for 20 bucks...
Just wish I would have known beforehand.. I think I left chunks of skin hanging up in there..

RE: LST2 Steering Servo Question
So, here's a pic.. You kind kind of see the THREE problems with how they line up:
1.) The arm from servo arm down to bell-crank is at an angle. I lengthened the arm a few turns to reduce the strain. Still, it's at an angle, probably unhealthy for the link on the servo arm itself.
2.) I had to dremel the bell crank arms to clear the servo deck... Barely..
3.) The links on the servo arms just barely fit under the front (heavy duty) skid plate.. Filed them down, they should fit now..
Anyway, I've just bought two Z590's, but honestly, after the enormous hassle of getting these new servos in there, I think I might just take my chances...
Anybody got any suggestions for how to improve those chances before I put it all back together?....
I think the main issue is the angle of the arm from servo to bell crank... I could I suppose file down the rear plastic servo mount and thereby reduce the slanted angle at which the servo sits....

I dont recall if my linkages were angled like yours are, but like I said... I didnt use the isolators. I'll pull my front skid plate off and post a picture of my 645's and the linkages.

RE: LST2 Steering Servo Question
Here are 3 pics of my servo/linkage install, with only the front skid plate removed. My linkages look to be at more of an angle than yours, but without the spacers installed, the height and angle of the servo seem to be correct. I didnt have any binding when I put it in, I just had a tricky time getting the control horns lined up perfectly straight since the truck was built completely from spare parts.
I had to shave the bellcrank down a little on the one side as well, to clear the servo case. I didnt need to take much off - no biggie. The case of the 645 is just a little bit taller than the 590/650's..
These pics are 800x600.. If they're too big, let me know and I'll resize them.
