• I'm pretty new to fpv racing, but in general the biggest issue is the motors, and how large a propeller you'd have to spin. 880kV motors rotate more slowly than the 1800kV-2200kV motors and 5" props typical for a 250-class racer. Of course, changing motors means changing ESCs, and a racer will have a smaller battery in the 1500 mAh range...

    Tons of stuff out there on FPV racer builds, but not so much here. There are some detailed builds and parts lists at as well, and a million frames to choose from. I have a 255 mm frame with 2300kV motors, 12amp ESCs, 5045 props, and either a Zippy Compact 1800mAh 25C or a Turnigy Nanotech 1500mAh 25-50C. If I had to do it again, and I will, I'd upgrade to Emax 1806-2280kV motors. You'll also be paying quite a bit more for a FC that can handle the GPS.

    I was thinking that my leftover IRIS parts from the upgrade would made a pretty nice, compact 600-class hex...

    • Would I still be able to use my Pixhawk? I mean its probably the most expensive piece of equipment I have

    • I am sure you could, but it would be a waste.  In FPV race, you would be flying fully manual and want the quad carrying the least possible weight.  Pixhawk is large and heavy.  You will not be utilizing any of the features, no compass, no GPS and no sonar, so why even choose Pixhawk?

  • Not sure what suggestions are you looking to get here.  In general FPV racing class are quadcopters in the 250mm range so frame of 200mm through 300mm.  What you have is not going to fit.  Sometimes you will find open class for larger size multirotors, but since it is "Open" you will need a rig that is light and fast.  In general, for FPV races, there are rules and regulations that governs your multirotor build from frame style and size to motors and battery capacity limits to FPV transmitter power.  I am not sure this is the place to get information.  You should join a local RC club or FPV Racing chapter.  Check out
