    Are you going to stock the 5040 gemfan props? They are (IMHO) about the best all-round sport props where you want a reasonable compromise between performance and durability.

    I've found the GF 5045 and GF 6045 to be no match for the HQ props but the GF 5040 props are really handy -- they are more flexible and handle my kind of "landings" better than the other GF options ;-)

    I've used similar looking "no name" props from other suppliers and they were crap (although these may be different). Almost without exception they'd throw blades at random, even when fresh out of the bag and never crashed. I got tired of going and picking up my quad after the regular "WTF? Why did that just fall from the sky" moments and found the GF5040 props much more reliable.

    I should pick some of these up from SZ I guess and see if they're made from better material -- who knows, they could be great!

    SurveilZone's 5040 props SKU: MR1137 has good quality since it is made of good material. We customize it.

    Very good props.
    Well priced and appear to be durable. I've yet to test-fly them
    Here a quick static thrust test and comparison with GF & HQ

    This is the revised test. On the first test I the ESC BLHeli settings were not optimal for the Cobra 2204-1960Kv motor. Motor timing was set to"Low" from a previous test I had done. This new test was done with a KISS 18A ESC

    Revised test


    First test
