  1. Motopreserve

    My First Build!

    As I mentioned earlier in the thread - I e had good experience (no failures) with the Vulcan PDB. IF THE PROCE IS TOO HIGH - I can't recommend a particular alternate that I've had personal experience with. I've only used the Vulcan, my own soldered squid and that disaster from HK.

    Just do some searching for PDB that can handle the current draw you will be relying on. The max your motors can pull should be the benchmark. Err on the side of caution and give yourself a little headroom. If you are looking to save some money you can always solder your own "squid" for the PDB...

    My First Build!

    It failed midflight causing a crash that wrecked about $100-$150 in parts. I did the math and yes, it was worth it to me.

    Problem with take off (Video) - back motors spin faster (i think)

    Definitely check the soldering - but I would think that the MR would fall out of the sky completely if you had bad/cold solder joints. The self-level may not be providing altitude hold, but rather just attitude hold. You also may have a bad board.

    Have you calculate the weight to thrust? What flight mode is it exhibiting the up/down behavior? I thought these KK2 were supposed to be decent out of the box - but famous claims and different experience :)
