Hi,

I am looking to climb as steep a possible.

I weighed my GOM and it came in at 3.5kg all in. Each plastic wheel with Hyrax tyre and memory foam came in at 175gms. I searched the forums and all say less rotational mass is best, unsprung weight good etc. It does well with the 540 23T brushed motor in stock form so far on a 48 degree incline.

I wonder what you guys run on your GOMs. 3.5kgs (7.7lbs) seems average, wonder how much wheel weights can I run before it becomes detrimental to the drivetrain. And can't seem to find any aftermarket axle weights short of changing everything to the junfac aluminum knuckles.

What are my options, or is GOM's weight distribution perfect and I shouldn't mess with it?

For a lil extra weight I went with a 2.2" wheel 1' wide. With 1.9" tires mounted.

I added SCX10.2 heavy str knuckles and brass from the 10.2 to the rear axle. Stock shock springs I cut 1 coil off and mounted them to the lower link location.
