MGM Programing Questions

Ok I ran the 62/24 on 4s with mgm settings changed (freewheel off, accel .013 setting) and it ran much better faster, flipping on its lid now... motor and esc were barely warm ... it was ever so slightly spongy down low so I think I will try 65/22 gearing....I could see 5s being perfect for me but I want this to be driven by friends when they come over so 4s is plenty for this ...I want to run 5s in my revo setup, but will try the 4s first
