RE: Any 4*40 owners with a 4 stroke?
yeah, i'm not too happy with the balance yet.
I have 2 ounces of lead in the tail and the 1700mAh battery is jammed up against the servos as far back as it will go.
I needed all of my up trim to get the model flying straight and level which indicates it's still nose heavy.
When i get home from work i'm going to see if theres anywhere further rearward i can mount the battery. I also have a smaller/lighter 1100mAh pack to try and see if that makes a difference.
I'm also thinking of getting a lighter 2-stroke up front and shifting the .62 to another model.
