Ok, i see this thread come up no less then once a week. probably more.
Usually starts out with........MY Steering Sucks. i don't have any right hand turn radius now? I just installed XXXX servo and my steering isnt right ect.......
Now For anyone that has installed one of the following 4 servos in your HPI Baja RC, you need to read on.
Mutiplex Rhino
Hitec 5745
Hitec 5755
HPI MG10v2 Full Digital
now these 4 servos need to use the adapter from HPI due to their slightly smaller size than the stock servo and the Hitec 805mg/5805mg servos.
so only the 4 servos (and any similarly sized servo) system will benefit from this thread.
Im using the Rhino and 5755 in my bajas, and Previosly a 5745. I am now using the PA Racing Mounts, and used to use teh adapters, and also have the Red Baja/Rhino servo horn using the farthest out mouting point for the linkage.
I have noticed, as many others have, issues when turning right. I now believe i have solved said issue.
When installing the smaller 1/4scale servo for steering, such as the Rhino, or Hitec 5745/ 5755, all known instructions say to mount the adapter to the Gas Cap side of the radio box, shifting the servo drive gear right (from the front view).
I have found doing this, moves the drive gear more towards the right hand side of the buggy, which in turn, can cause the steering linkage end ball to hit the top brace in its arc to the clutch side of the buggy. Also due to the centerline being moved, the turn left has to put the servo horn, nearly fully horizontal to induce full left steering.
To fix this issue, install all adapters to the clutch side (left side from forward view) of the radio box. with the PA racing mount, install the wide side to the clutch side and the thin to the gascap side. this shifts the drive gear back toward the center of the radio box. which now allows the horn to move fully to the right without the ball end of the steering linkage hitting the top plate limiting travel, (turning radius) to the right.
this also corrects the left steering as the horn no long needs to go near horizontal to achieve full left turning radius.
i always wondered if that shift from using the adapters on the gas cap side was causing this issue, and it certainly appears that is the case.
So put all adapters to the left side of the radio box (from front view) and reset all your Tx settings, and you too can enjoy excellent steering again.
hope this helps recover some of those steering quirks many of you have come up against.
Here are some pictures with captions to help you along the way.
This shot is to show the Rhino mounted in the PA bracket with the Wide side to the right (front view).
in these next 2 pics, you can see the ball end is very close to the top plate. with the servos mounted to the far right, the shift in the drive gear is great enough to put the end into the plate. Occasionaly the ball end would move past the plate, and get trapped under it, causing all sorts of steering issues. and some whiper arm breakage as well i presume.
Just imagine if the ball end was 1/3rd inch farther to the right? you can see it would hit the top plate, which serverly limits travel of the steering setup.
here is a pic of the setup in a full left turn
previously, the horn was basically horizontal to make full left
here is the pic of the horn at center. While it looks like it is in the 12:00 O'Clock position, it is just a bit past 12. closer to 12:30. i did not reset the horn on the servo, but if i did, i imagine it would be closer to the 1pm postion. I did have to move a fair amount of trim to re center after swapping the mount 180*.
here is a pic full Right turn.
