Hover One

To design a hovercraft or ACV (air cushion vehicle) that will be tested for speed, maneuverability and handling on various terrains like sand, water and gravel. It requires the participant to build a radio controlled hovercraft that could complete the specified track in the least possible time.


Prizes worth INR 35000

 Event to be held from 28th February to 1st March

Please post your queries related to this event at

    Round 1: Testing

  • This round requires the participants to drive their hovercraft on the given track mentioned under the track layout.

  • The width of the track will be around 1.5m.

  • The teams will be given ONE attempt.


Round 2: Maneuverability

  • This round requires the participants to maneuver their hovercrafts through the given track.

  • The teams will be given a maximum of TWO attempts.

  • This round is the final round.

The detailed slot timing for each of the participants will be sent over mail, within a period of one week to a day before the event. Participants are requested to keep checking their mail.

  • The maximum dimensions of the model allowed are 60cm x 50cm x 50cm (lxbxh).

  • There is no limitation on the weight of the craft.

  • The use of IC Engines is strictly prohibited. ONLY DC motors are allowed.

  • Use of ready-made actuators/motors, remote control units, electronic speed controllers and propellers is allowed                           .

  • Teams should bring their own remote controls, and they must operate at 2.4 GHz. Radios with any other frequency are strictly prohibited for use during the event.

  • Ready to use kits and readymade building kits are strictly prohibited.

  • There is no limitation on the type or number of motors or servos that can be used.

  • Participating teams will have to send a clear photo of their hovercraft and the 2.4 GHz transmitter by Sunday 22nd February 11:59 PM. Read FAQ's for further details.

  • Crafts found damaging the arena will be immediately disqualified.

  •  The minimum number of members allowed per team is 2, and a maximum of 6 members will be allowed. Only 2 members from the team are allowed to be near the track.

  • Only one member of the team is allowed to run the hovercraft during a trial.

  • Event manager's decision will be final in case of any conflicts.

  • Other communication devices are not allowed near the arena while the competition is on. This includes remote control of your hovercraft while some other team’s run is on. The organizers hold the right to check for these devices and their usage.

  • The time measured by the organizers will be final and will be used for scoring the teams. Time measured by any contestant by any other means is not acceptable for scoring. In general, the decision of the organizers will be final and binding in all circumstances.

  • There will be a certain number of check points on the track, which will be informed to the participants before the start of the run. If a machine falls from a height off the track or gets stuck, then it will be placed back on the last check point the hovercraft has passed. This will be done by the organizers.

  • Teams are not allowed to touch the hovercraft during the run (except if the team announces time-out as per the next rule). The timer will also keep running during this process.

  • Time Outs: A team is also allowed time outs of 90 seconds max, in case they feel that manual intervention is required to repair any damage or malfunctioning. A maximum of 3 timeouts can be taken. The timer will be stopped for the duration of the time out. However, the intervention has to be for a genuine reason. After the time-out, the hovercraft will be placed at the last checkpoint.

  • Teams should bring spare parts (Batteries, Propellers, and Motors etc.) to the event along with the necessary tools for immediate repairs. The organisers will not provide/sell any such equipment.

  • Rules are regulations are subject to change. If any changes are made, it will be duely informed to the participants.


   Round 1:

  • Teams have to aim for the best lap times. The lap time will be calculated as follows:

  • Lap time is the ACTUAL time taken to complete the track.


    Round 2:

  • There will be in all 3 checkpoints.

  • Crossing each check point awards the participants a given number of points The total points are cumulative, i.e. the points earned by crossing a check point are added to the points earned on crossing a previous checkpoint.

  • In the case of a tie in points, the least time in which the points have been secured will be considered.
