Threads mated with standard soda bottles, low profile detachable fin system, variable nozzle inserts and the Ultimeter Nose Cone, HydroLaunch system allows for maximum experimentation when building a water rocket.
Use different Nozzle Inserts with diameters 8mm, 10mm and 12mm to experiment with variable thrust profiles.
Ultimeter Nose Cone: A polyurethane nose cone weighing just 80 grams to make your water rocket aerodynamic. Specially designed to house the Ultimeter, this nose cone adds advanced capabilities to your water rocket game.

Do not buy their products. They are just trying to sell cheap Chinese products which seldom work. No ethics either.
Dear Mr Singh,
As already informed over email to you, these batteries are not drone batteries. These are regular LiPo batteries with a maximum discharge current of 2C, and charge current of 1C. Using them on drones cause irreversible damage to the battery.
Drone batteries have a high discharge rating, and can be found on our store. I am not sure how use of a product beyond its scope by the customer makes our company unethical. Good Luck with your future endeavours.
