Hi!

I have a Teksumo wing that I am really please with. I have a 1950 kv motor installed and flying it on 4S. However, I do feel like I do not have the top speed that I want and I am thinking that it might be due to the propeller (I am using a 7038R propeller). I do have really good low end but after 75% throttle more or less nothing happens with the top speed.

How do I know which way it should be mounted and in which direction should the motor be spinning with a pusher setup?
