Not sure about 35'-50'. Does not matter (actually I have no idea) Ground effect is a function of wingspan. V2 will give you the best ANGLE of climb at set conditions with a engine failure. Hope this helps

Here's to cheating, stealing, fighting, and drinking.
If you cheat, may you cheat death.
If you steal, may you steal a woman's heart.
If you fight, may you fight for a brother.
And if you drink, may you drink with me.
