Nuts those i can't comment on as i don't know them to give you advice.
Is this motor rpm happy or has it more torq like the GM motors??
If it is like the LRP or the Tekin you can drop a teeth or 2 but if it is like the GM you could ad some.
Just try it out and see what happends.
I thought my LRP couldn't benefit from revving more but it did.
I now use mode 8 on a GM esc with my LRP 10.5 stock( 5 cells) and it go's like mad on the straight but i loose a bit infield so i am gonna drop a teeth or 2 to see how it works out.
