Strength of Versaplanetary & PG-188

[Bob Steele]

If you pay attention to the recommendations listed on the Vex website you shouldn't have too many problems For mechanisms that are going to experience a bunch of shock loading, our team tries to use a final chain and sprocket stage to minimize this.

Some of the many possibilities for gear reductions are not recommended by VEX.... please take a look at this pdf from their website:

Depending on the motor.... you will see that some reductions are not advised. Primarily those that use the 9:1 and 10:1 gear sets....these have very tiny sun gears that cannot take the load. the only issues we have ever had have been with these 9:1 and 10:1 gears sets under loading.
