Hi!
Why do you want to know that????
Static trust is nearly worthless to know...it's what happens in the air that is important!
What kind of airplane are you going to use it for??

How much does it weigh?

I've got a OS 25LA on a Sturdy Birdy. It flies it OK but could do with a little more power.

My instructor thought there was a slight improvement when I switched from the zinger 9x5 to a TF 9x6.

Stick yours on a scale and I'll do the same later, it'll give some idea for comparision......

I think I remember this question from when it was first asked, maybe my reply got lost when the site went down... :(
