• TrailBlazers - Sky is the limit


    Problem Statement

    Design and build an aircraft that:

    • Can perform pitch and roll motion (yaw is optional)
    • Can fly around the given arena with a payload
    • Has a mechanism to drop the payload at the desired spot (controlled through a channel on RC)
    • Can land safely in the given landing zone

    Event Structure

    Event 1 

    Round 1: Manoeuvre your aircraft along a set path given to you which will require your aircraft to go around some poles in the arena followed by a safe and smooth landing, all within a time limit.

    Round 2: Perform the following in the given sequence:

    • Two underpasses (at a height of 2m each)
    • A stall turn
    • Half Cuba 8
    • Loop
    • Spot landing

     Event 2: Glider showdown

    Everyone having an aircraft of the specification provided can participate. Each participating team has to attain maximum height in 60 seconds (time will be recorded after losing contact with the ground). Once a maximum height is attained participants are expected to glide there aircraft at zero throttle for maximum amount of time. The longer a participant’s glider stays in air the more points he gains. There is a penalty for crash landing according to structural or prop damage. If your plane breaks completely you are disqualified.


    The arena consists of an open field of approximately 50m radius.


    All students with a valid identity card of their respective educational institutes are eligible to participate.

    Machine Specifications:

    1. An aircraft is defined as an object that has the four forces of flight, namely lift, drag, weight (gravity) and thrust due to propeller acting on it at any point of time.
    2. The plane should be capable of performing pitch and roll motions. Yaw motion is optional.
    3. The wingspan of the plane should not be more than 150 cm, while its length should be less than 150 cm.
    4. The plane may be hand-launched or may take-off from the ground. Use of any other launching mechanism is prohibited.
    5. Use of IC engines is strictly prohibited. Only electrical motors are allowed.
    6. Use of gyroscopes is not allowed.
    7. Participants must make all parts of the aircraft themselves. Usage of Ready-to-Fly (RTF) and Almost-Ready-to-Fly (ARF) kits is strictly prohibited. However, kits comprising of unassembled cut-pieces of Balsa wood are allowed. Use of readymade actuators/motors, remote controls and propellers is also allowed.
    8. Violation of any of these specifications will lead to immediate disqualification.
    9. Decision of the Judges, Event Manager will be final and binding.

    RULES :

    General Rules:

    1. Each team can take 3 chances at a take-off, i.e. two false starts and one final take-off. However, once the plane has been airborne for more than 10 seconds, no more take-offs can be availed. The participants themselves shall be responsible for any damage caused to the plane during a false start.
    2. The teams must adhere to the spirit of healthy competition. The teams must not damage an opponent’s aircraft in any way. Judges reserve the right to disqualify any team indulging in misbehaviour.
    3. Any team that is not ready at the time specified will be disqualified from the competition.
    4. The aircraft would be checked for its safe operation before the event and would be discarded if found unsafe for other participants or spectators.
    5. The organizers reserve all rights to change any or all of the above rules as they deem fit. Change in any rule, if any, will be highlighted on the website.
    6. The wind conditions are uncontrollable by the organizers, so any complaints of unfair advantage/disadvantage will not be entertained.
    7. The transmitters of all the teams will be safely secured by the organizers during the event to prevent frequency clashes.
    8. You are expected to bring your own battery chargers.
    9. The thrust source has to be electrical motors. Any other means of propulsion is not allowed.
    10. Electric sockets will be provided in the stadium for battery chargers. These would be standard AC mains. You are expected to bring all the supporting equipment for your glider. No complaints will be entertained in this regard.

    Event 1

    Round 1:

    1. Each team will have maximum of 3 minutes to complete the given path. Time will begin with motor initialization.
    2. The take-off has to be smooth and the plane should not jeer around for complete points.
    3. While flying around the poles, proper altitude is to be maintained (going above the height of the pole will lead to a penalty).

    Round 2:

    1. Maximum time limit for each team is 5 minutes. Time will begin with motor initialization and end at landing.
    2. Landing completely within the specified area will give you full points, steering outside will be a penalty.
    3. The underpass has to be within a height of 2m only.

    Event  2

    1. Each participant having an aircraft that does not violate general rules can participate.
    2. Each participant will be given 60 seconds to attain maximum height and their throttle will be killed. A participant can choose to kill the throttle before completion of 60 second and that time will be added to his points as bonus. Power kill can only be done after a flight time of 40 second or the participant will be disqualified.
    3. Time of 60 seconds to attain height will be recorded after the plane leaves ground or is thrown.
    4. After the engine is killed, participants are expected to glide for maximum time possible. The amount the participant stays in air will be added to his points.
    5. There is a penalty for crash landing.
    6. If your plane breaks completely you are disqualified.


    Event 1

    Round 1:

    1. Time Points(TP) = (180-T) ;   T = Time taken(in seconds) by the team to complete the run
    2. Performance Points (PP) = N*4 + M*2 ;  N = Number of poles successfully gone around.                                                                                      M =  Number of poles missed by height

    TOTAL = TP + PP

    Round 2:

    1. Time Points(TP) = (300-T) ;            T = Time taken(in seconds) by the team to complete the sequence
    2. Underpass Points(UP) = 10*N ;      N = Number of underpasses successfully performed
    3. Stall Turn Points(STP) = 20;            For a perfect stall turn
    4. Half cuban8(IUP) = 40;                      For a perfect half cuban8
    5. Loop (L)=20;                                             For a perfect loop
    6. Landing Points (LP):
      Distance from centre of landing zone Points
      Perfect spot landing                                          20
      Landing within a radius of 3m                       10
      Safe landing outside landing zone                 4
      Crash landing                                                          0

    TOTAL = TP + UP + STP + IUP + L+LP

    Event 2

    1.  Time taken to glide down (T) ;  T = time taken ( in seconds) by the team to touch ground
    2.  Power switched off  before 60 sec  (P) ;  P = time in completion (in seconds) of 60 seconds before killing the throttle . Power kill can only be done after 40 second of flight.
    3. Crash landing penalty ( Prop damage or break) = a;   a = 0.1*T
    4. Crash landing penalty (structural damage)       = b;   b = 0.3*T
    5. If your plane breaks completely you are disqualified.

    TOTAL= T +P - (a+b)
