I won’t be here Wed, Thurs or Fri, I have business in San Francisco and won’t be back until Sat, so lets assume that all gears are in place and there are no missing parts that you can see.

Can you get your instruction book, turn to page 13 and look at assembly 3, notice part MD4? It slips into shaft MJ1, then the hexagonal nut MH1 fits onto MJ1, which THEN slips into MD4 pin. If the MD4 pin falls out, then the MH1 nut won’t turn, thereby the Leopard won’t steer or pivot (the MG5 gear fits over MH1 nut), the shaft will spin, but not the MH1 nut. I suspect this is the problem with your gearbox.

Make sure the pinion gear (part MC6) on the steering motor is flush with the spur gear.

This has nothing to do with your Leopard, but mine. The very first time I ran my Leopard it would turn/pivot, but there was no forward/reverse, none at all! To make this short once I cooled down I grabbed my instruction book and noticed on page 13, in assembly 4 there was this MD4 pin that fit onto MH1, so I disassemble and removed MH1 nut only to find NO MD4[:@] , no MD4, no forward motion!! It had fallen out and I didn’t notice it.

Once you find the problem and put the gearbox back into the hull, hook up the motors and try a test run to make sure everything works BEFORE attaching the upper hull.

Oh and I forgot to answer your question about the Gun Stabilizer, theres a small instruction sheet that tells how to install the unit. You have to activate the Stabilizer every time you turn on the Leo, and the instructions are on the back.
