Hey everyone, I’m looking for a servo to stuff inside an electric Vesla and can’t get out of my own way. I want the AGF-RC offering for the power and for the metal horns that come with it. However, the power hobby 701MG is more affordable and has decent steering power at 7.4v.

All of that to ask, does anyone know if the power hobby comes with metal horns at all or are they all plastic?

I’m sure some folks will say plastic is better for breakage purposes, but I’m not gonna send this thing to the moon and I’d rather the rigidity of a metal horn to really move those wheels.

All the images of the PH 701MG show an aluminum clamping horn. Once my stock Kraken TS-560HV puffs smoke the PH 701MG is more than enough for a 2WD. Heck even if you have even a so so decent power plant the front wheels are more rudders than anything.

Great points. I thought for 2WD it was more than enough too, but want the dang metal servo horn. Thanks friend
 
Installed today,zero issues ,dropped right in.Yanking front tires hard.....!!!!! Burned up stock losi yesterday....One question is voltage, 6 or 8...servo rated at 6 and 7.2?

I thought they were 7.4v. Doesn't really matter really. Just an opinion but i would go with your higher voltage as their is always some voltage buffer/leeway.
 
1) I installed this exact same servo in my SBK (look at my recent comment, with photo, in your SBK thread). It first perfectly, provides more than enough power...and, yes, it WILL function perfectly at 7.4V (just set the BEC on the ESC).

2) Yes, it does come with an aluminum clamping-style servo horn. However, the holes did the steering turnbuckle are of a smaller diameter than what's needed for the SBK. Thankfully, the 'solution' is wow simple - just drill it out, first with a 1/8" to make the hole slightly bigger, and then with a 9/64" to make it just a hair smaller than the screw used to attach the steering turnbuckle to the servo horn. BEFORE you install the horn into the servo, use a screw/bolt to 'tap' threads into the servo horn. Because of the raised level of the horn, attach the turnbuckle from the underside of the horn (see photo, below)...have the bolt go up through the rod end, and screw into/through the servo horn, and then finish it off with the nut on top.

Once that's done, you can center the servo, and attach the horn to the servo (which should already be installed in the vehicle...note, my photo in your other thread shows the servo installed backwards, as the spline should be 'away' from the front, not 'towards' the front (as incorrectly shown in my photo in your other thread)...the below photo is the correct orientation).

As you can easily see from the photo, attaching the steering turnbuckle to the underside of the servo horn, but the topside of the steering bell crank, allows the turnbuckle to be almost perfectly parallel to the chassis. If you were to attach the turnbuckle to the topside of the servo horn, it would put the turnbuckle at an extreme angle, which would add stress to all parts involved. This way (ie. how I installed it), there's no 'stress'.

Thank you everyone for your support!!!!Ran buggy this morning at 6 volts,easy-to-use programming card, and still plenty strong. Best steering buggy has ever had.Going to get 2 more for backup for buggy and 5t 2.0!!!!!!

Thank you for your detailed response regarding the servo horn drill out. I followed your instructions and it came out perfect
