I’ve been unicycling for about 18 months now (on and off) and can seem to do
most basics- idling, forwrds/backwards, uphill downhill etc. The problem is that
I’m really bad at doing fairly sharp (as in radius of ~1.5m) turns without
waving my arms wildly and frequently falling off. Is there something basic I’m
doing wrong and does anyone have any tips to improve?

Cheers Nick
