Another way to get wind speed is just to change to atti mode, let the MR drift and read the speed telemetry. It also shows you the direction, by observing the MR.
I always like to take off in Atti and fly up to the hight I will be using,that way you get a good idea of what conditions are like. Often it is much windier up 100' and often in a different direction as well. Flying in atti will also give you a good idea of where the shear between wind layers are.
I think it is too easy to become numb to the elements always flying in GPS. A good pilot can spot where there may be bad vortexes at the edge of woods or around buildings and hills, as well as the effects of thermals, they cause winds, sometimes very strong, out of every quarter. You should learn how to read the wind and anticipate where you may get in trouble or the auto pilot in the MR will have difficulties.
Flying low wing loading RC planes is a great way to learn about the atmosphere we fly in. You become aware of trouble before you get in too deep. It is amazing to see how even in a fairly light wind 12mph or so, there will be strong vortexes downwind of buildings or even trees that can flip a model right over. Learn to anticipate and stay out of trouble.
Have fun and fly safe. This is a great sport...
