Thread: FPV 250 racing quadcopter

  1. #1

    FPV 250 racing quadcopter

    the frame will be in carbon fiber and aluminium and maybe some 3d print stuff

    here are the first renders of the FPV 250 racing quadcopter where is possible to see camera ajust, motor plate ajust for 5" and 6" blades, etc:

    Why is the live-video camera angled *DOWN*???

    Looks overly complicated compared to just a basic CF frame. Not to mention 2-3 times the weight.
    It may be better suited for a larger non racing quad.

    I agree. A racing mini quad should just have a single piece bottom plate, which already includes the arms (similar to the RealFPV Spanky), and an upper plate. That keeps it light and agile. A heavy quad makes it more difficult to do precise sharp turns due to bigger momentum.

    this is a concept to test
    the camera angle will be ajustble up and down....
    about the weight it may be reduced, and will be real cabor fiber and light weight aluminium...

    thanks for your coments

    It looks cool but why is the cam pointing down? Also, have you done any calculations on the weight? I mean, some kind of estimate

    Same concerns- bare frame weight and cam pointing down
    Frame structure looks solid enough for me as it is, but with all these aluminium parts and bolts it might be on the heavy side. Just replacing motormounts to 3D printed solid ones (like on Zee's Vortex Mini) would save a ton
    Cam down? C'mon man, it's not a white plastic toy for selfies LOL (let the fight begin...) If you only starting FPVing a copter- keep it level, and when you'll need to crank up the speed you'll want it to tilt up, not looking down seeing the ground only. Some tilt ~5deg, some nearly ~45deg up
    If you're a noob, copy 1:1 what somebody already flies without too much questions, you'll find the answers later.

    Pretty cool looking design and you're pretty good in that CAD program you used. +1 to everyone else's suggestions. Especially the arms; just go with cutouts from carbon fiber sheet.

    I prefer round tubes than flat arms- stronger, less springing flexibility and WAAAAY less air drag from prowash

    Hi tnkx for your sugestions....

    the cam is already up in the new project.....
    we already cut the first aluminium parts and they weight 4gr at the firs CNC pass...after all the holes and the second finish pass they will weight about 3gr
