Probably about the same but I don't remember actually calculating that. I
installed a brass tail wheel (great mod) and always put an extra litre in
the tail tank when ballasted.

Empty thermalling 48 to 50 knots... down to 45 in very smooth thermals.

Thanks Tom

Where did you put your CofG, mine is at 75%. Also what thermalling speed you
used when empty(if ever ).


Cheers
