according to my previous experience on the TB-10, they cruise at about 120kt; TB-10s are not much of a glider type, and yes im sure most people would agree with me that they sink like a brick with glide speed of 86kt. Think best rate of climb is about 75kt and best angle is 65kt. X-wind was 20kt??? (please correct me)
A nice plane to fly, yet the if you're flying it during Summer, the canopy will keep you warm inside the cabin.
good luck.
