Default Longest Steering Servo Horn???????????

Anyone know what the longest steering servo horn is from center of the servo mount hole to the center of the steering link mount hole?

I have used a racers edge and it seems to be about the same spacing as stock. I saw what looked to be an Integy on Mayfields Truggy. The stock one needs to be a little longer, Im not getting full travel with the stock one before it hits the side of the servo. RC8T.

Why would you even want to? With anything longer than the Losi horn (most horns will fit but the Losi is a safe bet and durable), you will have to dremel out the black plastic air filter guard and the steering geometry will be thrown off.

I would mess with your end points on your radio. On both of my 8's I run then endpoint to where the wheels stop turning and the value is always over 100 usually in the 110-120 range. A longer servo horn will increase the lever mech and make the steering faster. Racers edge horns are perfect.

Each raido is different so 120EPA on a Futaba or KO Propo is not going to be 120 on a Airtronics or Spektrum.

oh i dint know that, i been running by futaba 3pk for about 4 years.
i had radios that only go to 100% steering epa.

i did realize that if you add lets say, 2 degree toe out in the front u have to reduce the steering epa. i dont think really that u will use full throw while, your racing it only takes like ,steering to half way to get a buggy to turn.

hitec servos comes w/ good black plastic (thick) servo horn i been using to my rc8t ft & no problem (7955 strrng) ...................the horn got 4 holes so if you want more the 3rd or 4th holes is what youre looking for ........ IMO the alum. horn is not necessary

I know what picture you are talking about, it was the Hangar 9 horn, we used one on my race partners RC8T and it worked fine

I have bent several alum horns and I use the thick racers edge horns now they are made of a thick piece of alum no more bending horns. Plastic ones break, especially in a truggy.

I concur.....Ive bent many of older Racers edge and even a Non HD hanger 9 till Chad Bradley and Gary Guest showed me the CF trick....No more bent horns after that.

The new Racers Edge horns looks Uber Beefy and no chance at failing.
