Dan, makes sence and if someone had the money to play with or maybe went from rc cars to heli and had extra parts it might be worth trying. Some one could gow with a bigger motor for more torque then change to bigger grips but then maybe less stable. See lots to try I on one hand don't have alot of extra cash to experiment so I had asked if anyone had already done so. It might be worth an after market seller to try this as it seems alot of people are having power trouble with the norvel. Any way it was a thought. I guess I will have to wait for my vmax 7.. Alan
