    I tried swapping out the motors to Emax rs2205 2300kv. Can't fly. It has the shakes or quivers like the pid's are way off. Walkera motors fly great. I tried changing pid's and nothing helped, moved a little then took big jumps and never tried to clear up. Am I missing something? Pid's are at factory settings. Anytime I try to change pid's with stock motors same thing happens, shakes. It will fly but has the quivers.

    Check the rotation of the the motors. Iv got 1300kv 2205 on mine and it did what you are describing but I noticed the motors were spinning the wrong direction. Just swap any two wires on each motor. That should solve your problem

    Walkera drones are RTF and BNF and tuned for the components they are built with. They are not designed to support other hardware component upgrades.

    Motors need to be matched with Supporting ESCs.

    my f210 fly's fine with exact motors and 5045 bullnose twin prop however with dalprops it has bad oscillations on high stick but still very punchy. am half way through putting on some 30amp esc's will let you know how it goes

    You are changing props that have different characteristics.

    3 bladed props provide more lifting power. 2 bladed props provide higher speed. You put 3 bladed props on (E.g. Walkera F215) if you need additional lifting power.

    Changing diameter or pitch of prop blades (2 or 3 blades) requires precise tuning in the FC and supporting ESC. You can have fun playing with the swaps but if you are trying to improve the performance of the drone you would need to follow a precise tuning procedure with the appropriate test equipment.

    Having fun is fine.

    Be careful of the 30 Amp ESCs. If you use props that allow you to pull 120 constant amps through the mainboard and power regulators you may damage them and or the battery.

    You will need to upgrade the battery spec or you will end up with Voltage sags and FC failures mid flight.

    Let us know the results.

    Cheers

    p.s. Forgot to ask. Are the motors you are using the same KV as OEM?
