Here is a handy tool. If you are building your own kites you will soon notice that you spend a lot of time drawing perpendicular lines on Dacron Tape or Fabric. Measuring, marking, and using a straight edge to draw a straight line is very time consuming and not very accurate. Here is a 3D model of a Mini-TSquare designed specifically for drawing perpendicular lines on Dacron Tape. The lines will be quick to draw and perfect every time.
@Joneo Do keep in mind that despite both of these being sport sized, either of these foils can generate quite a bit of power. Don't expect to be able to just hold your ground as the breeze strengthens. In the right conditions either can hurt you. The 2.2 will pull a heavy buggy with a 200 lb adult in it 20mph down the beach. Total weight close to 275. Be careful and be smart please. They can yank you off your feet before you realize you are in trouble.
Ah well I guess what I meant by "a lot of people... have modified it" is really that alot of riffclown's customers are flying his modified kites, based on the posts I have been reading on this forum! 🙃
Thank you all for the input! This helps to know that while there is a noticeable difference between the 2.2 and 2.5, it is not a giant leap between the two.
