Grid fin testing

I used air breakes as grid fins as on spacex falcon 9. They do work and i recomend flying up high then let it fall down. There is a parachute but dont use it. Ive tried the rocket many times and it should fly straight up. Use the vtol one and break at same time as you fall down. (Left one) One more thing. The best way to use it if to fly up 6k ft min to fall down if not you will just drop too fast. (First ever build)

    @Mj423 Also may I ask you to share your falcon 9? Haha :) I also decided to use air brakes as I could retract and extend them much like the real one. :)

    Thanks @Mj423 I just tried it out works good but I have to say not a big fan of the pitch. Tho the roll was very good. Thanks for the idea :)

    Cool idea but I would recommend making it respond to roll/pitch so u can have 4 way motion I messed around with this idea in my falcon 9 build but I just had them extended based on pitch/ roll instead of rolling because as you rotate the pics you are decreasing the drag which is the opposite of how the rocket works still very cool just know that it will function differently then the real rocket
