i have the u-can-do .46 with a o.s 70 surpass and it will hover about about 5/8 or 3/4 throttle and is very stable in a hover.It is a very docile plane and i would highly recomend it especialy for the price!On my second flight with it i was getting 45 second hovers with it.and it is only my second plane not counting my stryker.
