Yep, I ordered from RC Model about a week and a half ago now and got my bits yesterday in the post which included the high traction arms and Speedmind motor heatsink plate. Now let's hope the high traction arms are a little more forgiving than the standard graphite ones

Its not the servo ear, its the turnbuckle rod when steering does to xtreme positions that grind the shaft.

i think should be the steel ball leg that from the servo saver causing you having this problem did you trim your steering properly? imposible to had this problem. the set screw of the ball stud that your screw on the servo savor too low

Default pro4 gear ratios

I see a lot of pro4 racers use the 64 pitch gears.
Where I race, it gets a bit dusty at times and even just a very small rock destroys the teeth of the 64 pitch gears.

Decided to go 48 pitch and to date, no problems except for getting to the best gear ratio for me. It is in this light that I am asking everyone's comment on:

WHAT IS THE BEST GEAR RATIO FOR THE FOLLOWING CONDITIONS:

Medium Bite, Bumpy, Cement finish track
V2 10x2
V2 9x2
Track is a bit technical, leaning lots of curves and turns - not flowing

Thus far, what I use are:

V2 10x2 = 69/27 * 2.4375 = 6.23

V2 9x2 = 69/22 * 2.4375 = 7.64

Can anyone assist by stating what gear ratio they have used successfully???

cone washer? OIC... I use a countersink washer for flathead screws mounted upside down so that the o-ring sits inside the bevel and secured with the original button head screw.
