9XL/3S gearing help

[JB3231]

I thought the MM Lipo cutoff only went up to 3S?

If I stay with the current 9XL and 3S for a while can you recommend a gearing setup? I have 16/66 now and ordered 20 and 22 tooth pinions. I'm looking for 40mph minimum. 90% of my running is up and down the driveway and around my cul-de-sac.

Here is a link to my previously sold LST2 with 5S. Wheelie's on command at any speed. That's what I want again. I just didn't want to spend another $1,000 getting there. Maybe I should just build another LST2. I'm just extremely disappointed right now with my current setup.
