Is it possible for "me" to make a hoverbike?

AI Thread Summary
Creating a hoverbike with multiple propellers is an ambitious project, but challenges include the weight of powerful batteries needed for propulsion, which can diminish lifting capacity. While some have successfully used small jet engines for similar projects, the original design referenced may have limitations in control and safety, as noted by experienced builders. High-end turbines, like the AMT Titan, can provide significant thrust but come with a high price tag. Building a multi-rotor aircraft requires advanced control systems for stability, suggesting that a hovercraft might be a more feasible and safer alternative for beginners. Overall, careful consideration of design, power sources, and safety is essential for such an endeavor.

Hi, I saw a video of a guy who made a hover and figured; hey, I should try making one too. I've a general design in my mind. His design had two propellers, one on the front and one on the rear. I wanted to make a bike with more than 2 propellers( assuming more the propellers, greater the thrust). My basic idea is two keep two at the back and two in the front. I don't really have much engineering experience or knowledge, so my question is in case I want to make this bike battery powered, how powerful a battery will I need? and also are there any powerful and fast yet light motors available in the market? or should I learn and 'try' to make one myself. I want the bike to atleast hover upto at least 3 feet with my weight. I weight approximately 80 kgs. Thank you! :)

The problem with using propellers powered by batteries is that the batteries themselves would need to be very powerful, and thus heavy.
Therefore a lot of the lifting power produced with that approach would be 'wasted' in just lifting the batteries themselves.

Could you guide me through exactly what sort of jet engines they are? thanks :)
 
I think the OP might be overstating what was created for the original YouTube video he mentions. I'm familiar with the video in question; colinfurze used a pair of engines typically used for powered parachute flight. But the craft is essentially impossible to pilot- it has no yaw control, and depends on him shifting his CG to tilt the craft. Also, the "bike" ends up operating well within the ground effect of the props. Colin himself calls the craft a "human blender" as well, because the exposed props are fantastically dangerous.

Regarding the hoverboard, that is a very impressive feat of technology, and the pilot is able to drive it very skillfully! It's probably using some high-end turbines designed for radio controlled aircraft, maybe something like the AMT Titan which provides 40 kg of thrust per turbine. Keep in mind the turbines alone are priced at 11k Euro each.

Building a multi-rotor aircraft requires an accelerometer-driven control system to modulate prop speeds to control attitude and yaw. Have you considered building yourself a hovercraft instead? Easier overall project, and much safer.
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
