The pump and the battery are not especially heavy and can be moved to the rifle if necessary. The bulk of the weight will be in the water since I estimate that the two tanks will hold about 8 liters each. So that gives about 16Kg (34lbs) of weight in the water. The weight of the backpack will be interesting, but I don't think it will be too heavy, and it doesn't need to be filled right up each time. The pumps push out around 4 liters a minute if run constantly; more than enough to give the kids a good soaking from a distance. So the water weight will soon disappear. In reality you only have to burst the pump to shoot water a fair distance so it won't be run constantly.

I think my most likely approach will be to modify a climbing harness which would be worn under the armour. Until I get the tank built and get a feel for its weight its difficult to know how much support is needed.

Hi Guys, I'm looking to build a flametrooper backpack and rifle capable of shooting water. Last year I build some electric water guns for the kids, and it would seem modelling the backpacks on a flametrooper design would be a great thing to do. The pump and electrics are pretty reasonable at throwing water 4 to 5m. A short video showing my water guns can be found here. https://www.facebook...408200273207206 My approach to building the backpack is outlined below. See diagram for reference points. A - To use 150mm (6inch) plastic tubes. These will act as water tanks. B - To build fibreglass domes to fit on the end of the tubes since I cannot find anything remotely suitable. C - To use 100mm (4inch) plastic tubes. This is intended to be decorative possibly containing the electrics, battery and water pump. D - To use MDF and fibreglass E - Probably copper tubing, but still figuring this out. F - Probably MDF and fibreglass. May put battery in this if I get one suitably sized. My initial questions and issues to resolve are: 1 - Dimensions of part D. I'm struggling to work out the appropriate lengths and angles. Does anyone have a plan view of part D with the sizing already worked out. 2 - Front of the backpack and attachment to the trooper. There are no obvious straps like a rucksack, so how is this "attached" to the trooper? This is probably the biggest issue as once parts A are filled with water this could be quite heavy and will need to be supported appropriately Please let me know your thoughts. Thanks. Nick.
