I believe you're right. According to the spare parts list, they are 45 tooth bevel gears. That said, the speed calculator doesn't have 45/10 as an option.
I agree. I have the X2 and it has 45/10 diff gears.

hiya brian. just had to say its a piece of art, and very useful for may people. the rc calculator. although a connect with progressiveRC and potential other databases, didnt bear fruit, its still a very handy tool, when the head computing seem to go slow.and planning is great...hope to see a new tool emerge from these potentials some day.
Much appreciated that its getting updated now and then, making it responsible work of art..use ful art :)
edit: sorry had an work/art/tool problem, bad english..surprise!
