I think Cobra has now changed to a vertical acting jack like what John has. On at least some trailers.

I once built a dual scissors jack for my DG400 using two electric car jacks similar to this one:
I replaced their cheap controller with heavy-duty (10A min) switches. The neat part was that I had one jack on a reversing switch. This allowed me to tilt the fuselage which is very useful in getting the correct dihedral angle during assembly. I powered the jacks from the glider's battery.
