We used to operate IS28's at Camden, and I have 300 hours flying them(mostly 20 minute flights...)
They spin very nicely and predictably but are sensitive to c of g.
I flew one once with the front seat passenger (weighed) just over the placard limit. At about 100 feet we hit a thermal: the nose rose and continued to do so despite application of full forward stick. I thought my number was up and was reaching for the release when the glider suddenly responded and a normal airotow resumed. Very scary.

I've attached the w&b for an American IS28 fyi

No. It could just have easily been the kid in the front seat grabbing the stick. Or his mother. Maybe a result of panic from the radio warning.

I'm cool with consenting adults only, flying in gliders. i.e. you must be 18 or older.

Perhaps somebody here operates an IS28? If so please give us the weight and balance numbers and cockpit placards and we can see what 5 to 7 Kg of tail dolly left on can do.

There have been numerous instances of gliders flying quite successfully with the dolly attached. It is also a fact that gliders are tested with the C of G 20mm behind the placarded aft limit including spin recoveries.

I agree with Tom. Radio warnings can hurt as much as they help. Haven't we had a couple of nasty damage accidents which would have only been normal belly landings if not for the last moment attempts to get the gear down?

This season has been a terrible one so far in North Amercia for fatalities. One 11000 hour pilot and aircraft mechanic on r.a.s. recently said he maybe should maybe reconsider his involvement in the activity.
