Servo Arm Centering - Subtrim vs Linkage?
#16
It depends from car to car. With my losi I've always used a little subtrim to get the arm pretty centered. Your left and right epa adjustments should be relatively close. So you don't want the right epa to be at 100% while the left EPA is at 40%.
Honestly, the subtrim vs linkage tradeoff is wayyyyy more noticeable with onroad cars. Making sure that you have correct EPA adjustments is a lot more important.

are you using a cheaper, diginal hitec servo or a analog hitec servo ?
because ive had center problems with them a lot.
i use a futaba coreless, diginal servo now for my throttle and it centers good .

I agree with the KO Propo guy.
I always setup my linkages mechanically first, getting as close to centre as I possibly can before adjusting my radio ( and I also make sure my radio is zeroed before adjusting anything )
Then I use sub-trim to adjust my servos to dead centre, after that I setup my EPA. The steering is always equal from left to right, and at maximum throw.
I find it quite simple to do this, especially if you just use a new model, or reset your current model on your radio. I also use Hitec 7955 servos, and they centre great.

ok so you set the, steering/throttle trim to 0 and than add a little bit of sub trim before you put the servo arm on ?

Hey its an honest question that i've yet to find the best answer for. I may end up just doing as i have in the past and as the ko pro gm suggested. But if you've ever googled the topic you'll see what i mean. Some claim to center it via subtrim, others claim to just adjust the linkage.

Thanks for the thought.

Well i guess i've come to the conclusion that setting the subtrim is probably the way to go. After seeing a few more videos on youtube and a few articles written in magazines and online, its apparent that is the accepted practice for getting the servo horn centered. I was honestly hoping more people would back up their arguement one way or another. And i've even found a way to do it manually by opening up the servo itself and messing with the gears to get it exactly center, but i don't really feel like voiding the warrantee on them quite yet, they've not even been out of the packaging for a few days, so we'll just go with subtrim and call it good.
Anyhow i appreciate the feedback, as always. Maybe tomorrow i'll start another topic we can argue over
