im blind or i cant find the gear ratio!

I did originally order it from the Sussex model centre but there were long delays in getting it in from the manufacturer so instead I ordered it from cornwall model boats as they had it in stock and it arrived within 4 days!
As for the gear ratio I am using, I was planning on using a 2:1 ratio with normal pulleys but now have ordered timing pulleys instead with the same ratio. But the ratio depends on what voltage you run the motor at, I am running mine at 24v but my gear ratio is still very high so I may have to change it to 3:1 or 2.5:1.
I have already asked this on my build thread but might as well stick it up here as well, is the name invictus taken?
