Why asymetric steering bellcranks?
Howdy yall
I've had this one on top of my head a few times but never got to ask... but as I'm working on getting the LXT ready for action in May, it comes back to the surface again:
why the steering bellcrank asymetry on the first-gen losi steering bellcrank design? What is the obvious bit I'm missing here? Why the off-center hole and the longer left bellcrank?

Thanks

Re: Why asymetric steering bellcranks?
mmh... that certainly influences ackermann angles, but in an asymetric way...

Possibly for roundy round racing ? Or someone made a mistake and set the machine up wrong ?

Re: Why asymetric steering bellcranks?
My thoughts were that they optimized it for a centered servo, which moved the crank over a bit, and putting the cranks too close would not be optimum. By offsetting both the sweep is somehow corrected with the geometry of the longer input side. I have NO idea if this is why, not any proof, but it was always my feeling

Re: Why asymetric steering bellcranks?
My RIGHT bellcrank is longer. ha ha
When I got my JRX2 I also noticed this. I looked around at aftermarket / period "hop up" steering kits and they did not seem to be asymmetrical, further intriguing me. Maybe it's one of those Losi "one eye covered" inside jokes?

Re: Why asymetric steering bellcranks?
I think it was because of the original servo saver bendy arm setup. It may have been a work around to extend the the bendy arm and move the hole forward in the rack as they may have found the equal length drag link / driven bendy link resulted in too easily broken bendy links. Butt I’m only spitballing here. I think this flawed design results in the car having a tighter left turning radius. Goofy as hell.

Re: Why asymetric steering bellcranks?
Thank you for asking the question, Lonestar. I have always wondered this myself.
Something clever goes here...

Re: Why asymetric steering bellcranks?
From the man himself.
"The JRX2 originally only had a flexible steering arm as a servo saver (not such a great idea). I wanted it to be as long as possible to reduce the strain (more travel) when hit. Since the arms were offset only one could be that long. I would do many things differently in retrospect! I was at the beginning of my learning curve at that time."
