1. Shaft
- small shaft like 6mm is sucked, it zig zag in the water expecially when more than 1 meter long.
- use 7.56mm or higher as long as you dont mind the weight, it's more accurate.

2. Rubber
- Well you will surprise to knowing that smaller rubber give more speed.
- use 5mm rubber
- or if you cant get any, use 3mm(thickness) and 1cm (wide) of tire rubber.
- rubber should be 1/3 shaft long.

3. Handle
- You can make up something that fix your hand (maybe like gun or just stick). as long as it dont weight to much. (wood is better here as long as it's float)

Now,
- make a hole in your handle that fix shaft diameter.
- tie rubber at the rear of handle.
- You're done.
