I hear what you're saying, but to optimize the use of the .46, you want to add the least amount of weight possible. If the plane is really that nose heavy, you should try moving some stuff around, and when you're done moving stuff, add weight to make up the difference. The engine will have power to pull extra weight, but added dead weight to a plane will really slow down the responsiveness; it will roll slower, pitch slower, yaw slower, etc. So you will be slowing down the responsive time and increasing the speed and power, which means you will have much less control. Try moving stuff around, it will be worth it!
