Default Servo horn

Hi guys. I'm looking for a direct servo horn to run off a futaba servo. I tried the dynamite one down one hole from the top but at full lock it touches the drive shaft. If I go down to the one below that I can't achieve full throw. Any thoughts out there on a horn that works?
Cheers
Simon

Xray servo saver works. You may need to shim the ball on the rack a bit to clear the shaft.

So I have to explain again the main ideas of red dots in the flex settings of our setup sheet ( both for top deck and lower deck also):

In case of somebody will be able to transform these rules to the more clear and shorter form I will be very grateful.
I think it would be more clear to use the red dot to indicate where the screws are fixed, and then have a separate check box to indicate the st09, similar to the check box for the at21s for the lower arms.

I agree. Since the red dots are used for the bottom chassis screws, this only makes sense. That is what I thought it was until I was trying this new setup posted and it only had 1 hole shown.

Simon,

Please follow the Instruction Manual:

1. 17,5-18,5 mm servo arm length.
2. 3,25mm shims under AT21 ball on the AM09 steering rod.
3. Steering rod travel limiters ( protruding SS3x12 set screws tips) on the bottom face of AM09 steering rod.
4. Exactly 90 deg at the neutral servo arm position.
5. Exactly equal length of both steering links.
6. Cut off the tip of the P13-1 ball over the cental ball of the servo link as in the Instruction.

Additionally ( from the old instruction for A700):
7. For Tamiya servo saver and 16,5-17,5mm arms you should use 3,75mm shims under AT21 ball on the AM09 steering rod.

Some drivers bend the servo ST21 steering rod a little bit to get bigger clearance to the top deck.

Simon...

I use xrays nt1 stearing arms (horns) they are a perfect fit for any servo, sturdy enough and just the right amount of give when your in a big crash.. The package of servo horns are around $6... Sorry don't have part numbers but if you check the web you will find them.. Hope that helps out...

Hi guys, yes great help. Thanks all.
I have been running the A700L in New Zealand which has very low traction conditions and we don't use tyre additive down here also. The car has been performing very well to the extent I have bettered our local track record in 13.5 boosted over my yokomo BD7 that I was running. We have our National championship coming up next month on a big bumpy track so will look forward to unleashing her on that track!
Good luck to all the competitors at the IIC
Thanks
Simon

Is there a good way to take off the wheel hexes? Now that the plastic locking spacer holding the hexes are in place, I am not seeing a good way to get it back off. Figured someone here would know a good way to do this.

i don't know if its a good way -- but i spin the hex so i can grab a point, and pry it off the am06s/am06 using my ride height gauge. this way it just pops off with minimal force.

Hey Travis

I usually just give it a sturdy tap on the axle and the plastic locking spacer comes of pretty easy, after awhile of taking them off and on they need to be replaced.. I hope that helped you out

see Larry's setup at http://www.awesomatixusa.com/p/setup-sheets.html

Larry Fairtrace Club Race A700L 17.5 Blinky Horsham RC USA Horsham, PA 5 October 2013

the major changes from past setup are-
* addition of 0.4mm front and rear to the dampener (A measurement)
* measuring droop from under the arm. laying the chassis on a setup board (make sure the p06 & set screws don't hang low/make the chassis rock) measure with a droop gauge from the "inside" of the car, making a 90 degree angle with the setup gauge and c04 arm. the setup gauge should just be touching the button heads under the arm.
