I have been flying my 3.75-4.0 metre span gliders on the slope.I prefer to fly slope,and do not aerotow the 1/4 scale gliders.I am yet to maiden my ASW 27-4.20 metre,and Kestrel 17-4.25 metre at the slope,both these models will be maidened at mount hollowback,and will only be flown there, thereafter.They are expensive model$,and the landing area is large and flat,so it is the best slope for them.UPDATED MARCH 2013-Finally maidened both the ASW 27 and Kestrel 17,both are good flyers,the ASW 27 flies better though.

Don't worry,

towing 4meters gliders is not that difficult, what you need is a good pilot ahead and talking together to know exactly what you both gonna do ... I know it's a thrill and could be considered as not confortable; keep going on slope flying and HAVE FUN !

Basically there are more days that are good on weekends, here in australia, that are more suitable for slope soaring than aerotowing.Luckily we have different slopes to choose from, that can be flown in any wind direction.
