main gear-modify servo is this what we should cut out

[rox2007]

attached is the picture of underneath the main gear. i just want to know if the part circled red is what we should take out

[ed1380]

you cant really take it out. i think.

if you cant then cut off the part of the pot that's supposed to go in that hole

[rox2007]

if i have a drill cant i drill it out. make it rounder so that the large gear can rotate freely.

[ed1380]

yes but it'll weaken the gear. it's already plastic and weak

[bukowski]

you should be able to pop it out with some needle nose.
I had trouble with metal geared servo's with a ball bearing, it did not want to come out, and you can just cut the pot head off, like ed said

[rox2007]

but if i made a mistake with the position and i want to adjust the position. am done for

[ed1380]

if you're afraid of that then you could do this

just do what they say. when they say solder resistors to wires. do it. i tried to be cool and solder it directly to the pcb. well now IDK if teh servo works. it's all finicky

and this is why i dont use servos

you've never used servos ever?

I always do this method, it always works!  Just make sure to use precision resistors with a tolerance of 1% or 2%, more than that it gets the servo confused slightly. I once used a 5% tolerance  resistor unknowingly and all that happened was i had to send a pulse of 153 to center it . a pulse of 103 to make it go to the leftmost position, a pulse of 203 to go to the rightmost position
