The water is pushed into a water channel in the Second stage, through a channel in First stage and the Housing, where a silicone tube is connected. However, if you do not like this feature, you can just uninstall it and never use it. In addition, it has four blades, which help with sharp cornering and prevent spin-outs. It is adjustable with a single screw - the same way as you would set trim tabs on a prop boat. The ride plate lifts the stern of the boat and keeps the bow down, which stops the hopping effect completely. Many of my previous boats suffered from hopping when achieving higher speeds and this feature has finally solved all these problems. The range of movement of the shaft is exactly 60 degrees left and right, so there is no need to set the range of the servo movement on the transmitter. When you need to do some maintenance, for example change the servo, you only have to loosen the servo coupler and slide the shaft out. It uses a rubber O-ring as a seal around the steering shaft instead of a traditional rubber bellow. Therefore, there are also less joints between the moving parts, which reduces the backlash. The advantage of this system is the simplicity - there are only 2 moving parts in total.

It is my new system where the servo is connected directly to a rotating shaft, instead of a pushrod. This is the only way I have found to achieve life-scale jetsprint handling on a RC boat.īall steering. They give the pump better overall handling, consistent performance and instant priming (the delay between the moment when the intake is in contact with water and the moment when it actually starts pumping the water). Includes part list, print settings, assembly and installation guide.Ģ-stage configuration, meaning it has 2 impellers and 2 sections of stator vanes. You can assemble it and install it into your RC boat. You also get a STEP file of the whole pump, ready to be edited to your needs. You get 12 STL files for 12 parts of the jet drive, designed to be FDM 3D printed with no supports.
