your battery leads are labeled on the fc. red is plus black is minus. the fc can be mounted how ever u want. put the rubber garments in the fc and mount it in the bottom u will need some m2 4mm screws are 5mm. i suggest buying a small kit.

thank you. actually i see that you went from the top on the battery lead in the last photo. it looks like I'll have to procure some additional screws... wish they would have been included with the kit.

just make sure u use two rubber garments for the mounting of the fc. one in the front one in the back. look on Ebay for 2m 4mm button head screws

no not really it is pretty much stock betaflight settings. with my rates . nothing special and the crazybee f4 pro boards are really easy to setup . just make sure u turn on anti gravity and dynamic filter . pids are stock however and did raise the d gain to 35 on roll and yaw .  If u run into any problems give me holler on my channel JeremyChotto

Thanks man. i seen a lot people doing throttle limiting did you?

no I just don't use the top of my throttle don't really see the need for it for me . once u fly it u will get the feel for it and know that u don't use all your throttle . don't get me wrong u could but I like to keep it simple and if I want all my throttle for some crazy reasons it will be there. u will know were your cut off point is again this just my personal preference I don't do throttle limits.  set your tpa break point in the pids tab in betaflight to 1460. I like my feedforwad set to 100. rc rate 1.15 roll and pitch 1.20yaw super rate 80 try 75 first .make sure u have air mode turn on mine is on a switch.  i run 8k2k for my pid loop on a f4 board of course. it is going to fly nice on stock pids betaflight has come a long way. don't forget anti gravity and dynamic filter turn on.

Awesome thanks for all the great feedback

yes I had to make nice mini silicone wire extensions. The motor wires are to short. plug and play is awesome. This primo flys so good no vibrations and these motors are a beast

nice!
i heard the motor connectors could rob some power and efficiancy, you add a second one :-) will be very handy for building. if you try it without motorconectors would be nice if you share experience about it. thanks for posting

Thank u my friend. I don't feel the connector takes from power or efficiency. Don't get me wrong u might can gain 5 r 10 percent more power soldering directly to the board.  I think the battery connector plays the biggest part in which I am using 20awg wire and xt30.  I am fairly good at soldering but for me to be able to plug and unplug the motors is very useful for me. Think about all the brushless whoops coming out today just about all of them have plug and play connectors.  These little quads are so fast and powerful I don't think u are going to notice anything different but I will keep u posted. As far as flight time on this quad I am getting 3and half to 4 minutes and that is getting on it hard. My motor wires were to short that is way I made silicon wire extensions.  Thank u again

3 to 4s nothing is impossible my friend but I don't really see the need for it on these builds. U are going to want to try to stay light and on 2s these quads have all the power u need . 3 to4s would be getting really heavy and for me take from my acro flying style.  U can do 3 to4s with larger props and thicker frames. trust me stay within 40 to 45 grams r under and these quads have all the speed u need . check out my flight on the toothpuff on my channel JeremyChotto.  going to upload the primo soon.3 to 4s is not needed on a toothpick type build. these quads are beast mode on 2s.
