Default Servo install problem

I have an HPI RS4 rally I'm trying to build up. I have a Futaba steering servo for it

The way the servo mounts is sideways so the throw arm is off to the side. I seem stuck to one place to mount it. However, the throw arm is a "+" shape and the lower part is under the chassis line

I wouldn't worry too much about it if it was strickly on road, but because it's a rally, I'll like to do some dirt stuff with it as well. One hart hit could break it

Can that throw arm be cut where ever it sticks down (As well as trim whatever else sticks down at full lock)? I can't see any damage in doing that as I'll mount the rod to the top of it

Or should I try to elevate it? ( I was able to order the tree the servo block comes on, but got one, so was just going to make one if need be)

Either get a better suited servo arm, or cut any legs of the stock servo horn off that get in the way.

I can't remember the last time I saw someone use a stock servo arm though...

Going to HobbyTown to get a new spur gear, servo tape (for the on/off switch), and I guess I'll get a throw arm also

Thanks, I just wanted to make sure trimming it wouldn't damage it... I bought their last servo in stock, lol

No, trimming the servo arm won't damage anything.

If your car doesn't have a servo saver built into the steering [I'm not familiar with your car], you may want to get a servo saver instead of a rigid arm.

I'll look into it, thanks

The guy at HT said that the horns are meant to be trimmed when you figure out which one you're using... but you need to be sure you get everything set up and working before trimming, or you need to get another horn, lol

EDIT: I happened upon it in the manual, and I do have a servo saver nut

EDIT EDIT: I just found the effing servo mounts!!! RAWR! Now I can install the servo tomorrow
