I am wondering how much additional weight is too much for my blade cp pro. I want to add a fuse to the main motor and the tail motor, but I don't particularly want to solder the fuse directly to the wires. So with fuses, and fuse holders I would be adding 15grams to my model.

My bigger battery is an additional 20 grams.

Is 25grams too much additional weight for these things? What would be a good aditional weight to stay under (for upgrades like a metal head, etc)?

Thanks for your input.
