LRP Sphere 2007 - X11 5.5 - TRF501x - Gearing?

[Fiddybux]

Hey all,

Just ordered the Sphere 2007 edition and a 5.5 X11 motor to go in my 501x.

Wondering about gearing options?

What would go well with an 87T replacement associated spur?

Also, what would go well with the stock 96T spur on the 501x?

How can I adjust this for more punch / less top and less punch / more top? Is it just like with brushed, i.e. raise a pinion for less punch / more top (plus hotter motor) and drop one tooth for the opposite?

Thanks all.
