Losi Ten-T Conversion

Brian, what do you estimate the top speed is on your truck with your setup? I have decided to base my conversion on yours. I am new to this and I want to get it right the first time around. The only thing I may change is the Tekin RX8 combo due to cost (any suggestions for a cheaper alternative?) or is it basically you get what you pay for. I hope you don't mind.

I tried your Top Speed Calculator but there was too many values that I did not know the answers to.
