SUMMARY

This discussion focuses on building a small, remote-controlled hovercraft utilizing magnets and air cushion technology. Key considerations include the use of a powerful fan to generate lift without a skirt, similar to helicopter mechanics. The feasibility of a magnetic levitation (mag-lev) system for a mobile vehicle is questioned, emphasizing the need for specialized tracks and high-speed electronics. Participants suggest exploring toy hovercrafts as a starting point for design inspiration.

PREREQUISITES
  • Understanding of air cushion mechanics
  • Familiarity with remote-controlled vehicle design
  • Knowledge of fan propulsion systems
  • Basic principles of magnetic levitation
NEXT STEPS
  • Research air cushion technology for hovercraft design
  • Explore remote-controlled hovercraft kits and toy models
  • Learn about fan selection and propulsion efficiency
  • Investigate magnetic levitation systems and their applications
USEFUL FOR

This discussion is beneficial for hobbyists, engineers, and makers interested in building remote-controlled hovercrafts, particularly those exploring innovative propulsion methods and stability systems.

I am looking into building a hovercraft, but i have virtually no idea where to begin. I could use a bit of help. Perhaps something that uses magnets...
Thanks for any help.

I'm sorry, I didn't specify. I want to build a small, remote-controlled, low-speed, levitating machine. maybe these specifications will give me more results.
Thank you for any help.
 
There are small toy hovercrafts for sale as well, sounds like a fit from your description. Its all about the cushion of air, if you have a powerful enough fan you don't even need to skirt to assist (like a helicopter or Harrier jump jet) but now may need some stability system to control pitch/yaw/roll.

Unless you have a special track and lots of high-speed electronics, a mag-lev system like some of the experimental trains is not going to work for a highly mobile vehicle.
