Did you change ANYTHING on the vehicle/radio before, during, or after the Orion > Tekin ESC swap...? Don't really see how that can contribute to losing steering throw, if nothing was changed on your end, other than the ESC. Should be same as before.

I completely agree, it doesn't make any sense. I didn't change anything going from one ESC to the other. I reset all end points to zero before calibrating with both ESC's, and there was still a variance in the total throw of the servo. I might try adding a new model in the radio and re-calibrate to see if that makes a difference.

the d/r is at 100 and trm and subtr is at 0. should i reduce the epa to 100 and start over again? lol

Correct.

Just to be thorough, if I were you, I'd make a new 'model' on your radio, which will take everything to the defaults, and go from there, following the page(s) from your Futaba 4PL manual, that I have attached above.

This should help

D/R is correct. TRM and SUBTR is also correct for default values. I'd personally reduce the EPA to 100 for both directions on your steering channel.

I'd also check to make sure that your servo and horn are splined correctly, in relation to the 'dead center' on your radio.. i.e., have you driven the car yet with it not going full-lock in either left or right, yet? if so, did it drive straight right off the bat, or did you apply trim/subtrim to the steering... if so, how much?

With all values at zero except for the EPA which was kept at 120 my servo horn is at 90 degrees with everything at zero. i have been racing the car without getting full lock. it drives pretty much straight. i have loosend up the ball cups that connect from the horn to the rack tried to make it a little longer to see if that helps and didnt.

Thanks

How about the turnbuckles from the rack to the steering knuckles?

I'd take them off, make sure both are measured to 80.5mm, from the end of each ball cup to another. Also, make sure the turnbuckle/rod from horn to steering rack is measured to 33.7mm from end to end.

If you're still coming up short on full lock, I'd take the rack-to-steering knuckle turnbuckles up to 82mm length.

Let me know if this helps

This isn't a sale thread. Get your overpriced nonsense outta here.

150mm, 175mm, or 200mm. Get some and make it your bitch!

Yeah, go ahead and search "steering throw" in the 22 thread. 46 results clearly indicate that other people have had this problem before. If you notice most every one of the people that have previously had steering throw problems in the 22 were using Futaba transmitters. If he increases the length of the steering turnbuckles it will just increase the toe in. This will result in more steering throw on the outside wheel, but less on the inside wheel. Not to mention what increasing toe in will do for the handling of the car.

Kompressor, what you need to do is turn the EPA up all the way, and check to see if your getting equal throw left to right. If so the only solution is to crank up your dual rate. This should increase your travel enough to get you full deflection. If the throw is uneven by a significant amount, then you will have to play with servo horn placement and servo horn to steering rack draglink length. On my 22 with the horn placed just clockwise of center (set per the instructions) i could not get full travel to the left with the EPA all the way up. So I had to move the horn to just counterclockwise of center, and then lengthen the draglink. After that my EPA's were much closer, and I could get full travel. This was with a Airtronic radio.

wow i guess i got to do the same thing!

my d/r is all the way up which is 100% and the throw is pretty even, only way to get full lock is with gnarly toe out...
