Well I just finished the hypertune! Not all that hard, just a bit of a pain. The hard part is getting the glued on worm gear locking rings, but a blow torch did the trick
To be honest I'm not sure what the point of all the calculations are to find the right teflon spacers - both RA and DEC ended up needing spacers that were about 10 times smaller than the smallest included one...
It does make a huge difference to how smoothly the mount works - balance is extremely sensitive now. The motors sound a bit different too, but that could be the placebo effect
I will find out if there is any difference to how well the mount performs for AP tomorrow night weather permitting
