If none of the motors will arm and spin now, even after cycling battery power, you may have fried a connection somewhere or the flight controller. The pop may not have been the esc itself but the flight controller, power board... I would check for loose wires that would have touched, maybe...

Just over the boarder in Sioux Falls.

Sorry, was referring to Minnesota.

Which part?

I don't think you would notice a difference between 2212 and 2312 same kV, 2312 should have a slight rpm lead at max throttle but also weights a little more. The more I thought about this, the more I didn't like my response. I think you could actually get similar flight times from either motor...

I am not familiar with the Iris, but with 3DR you will probably have more room to grow. The blade may or may not be simpler to get up off the ground and flying, Horizon is usually pretty good at that in my opinion. 3DR's autopilot is a favorite among many people here I believe though I have...

Within reason you can use the same prop and aren't necessarily over propping anything. Just know what your equipment is rated for to start with. Many motor prop tables overlap significantly between 3s and 4s. At the 900ish kv range you can run a standard 9x4.5 DJI prop with a 2312 on 3s or...

There is a ridge on one side of the male JST connector as memory serves, you would have to distort the shape the connect to force them together wrong... I think the JST gives a better lock up in my experience, I have betters for a VooDoo micro quad that actually have both connectors on a 1s...

What is a tight budget for Drones? You might look for something like the Phantom 3 Standard would be a good start or if you have a gopro or willing to get our own gopro, a Blade Chroma with no camera can be had at a reasonable price I would think.

I have been known to use a tie down strap, a cinder block, and a little time to lower a battery from say 4.2 volts to 3.9-4 volts if it is going to be awhile. Three weeks is not likely to do damage, just don't make a habit of it so that 3 weeks becomes 3 months. :D I also have a couple light...

3s vs 4s question, would probably just come down to the weight of the drone. Do you need the thrust the 4s system can create? If the 3s system would put you under 2:1 thrust to weight, run 4s. To just hover around, I would think the flight time would be similar as you are running the motor at...

Assuming you are running the same prop, the battery is going to be less strained by a 800kv motor than a 920kv motor, the lower kv will not try to spin the same size prop as fast. Too much junk into one thought that ended up being incorrect without more information, in my opinion. Re-word not...

More economical and more reliable can be tough. To reduce power consumption, reduce rpm (small kv number). One problem you will run into is that a good motor for 10" isn't necessarily the best motor for 12", a motor that works well with one of the sizes could be stressed or under powered for...

I have had good luck with Pulse and just started using Tattu. I have also had good luck with Turnigy for a cheap battery. They are batteries and at that they aren't the most stable battery in history (in my opinion) and probably all brands have had problems or at least had people blame their...

I have been on both sides of the fence. I started off thinking I needed CW/CCW to prevent random problems. You will just end up spending extra money and if you need a replacement nut, CCW can be hard to find and if buying from a hobby shop by the nut or pack of 4, terribly expensive. I still...

Throttle control takes time and practice, some of it is fine motor skills that you may not have used for awhile or ever and some of it just getting use to how it flies. I seen several new pilots fly my beater drone like a pogo stick, just takes time. Otherwise, make sure you have not limited...

If you like to push the limit, Google the specific esc to see if anyone tried them with 4s. Otherwise, 3s isn't terrible, majority of mine are just that. To drop from a Hex to a small quad you would probably need smaller batteries anyway. You can build a pretty quick 3s 150-220mm racer/acro...

Out of curiosity what did you adjust on the kk? I would have guessed it an adjustment on the remote but not familiar with all of the firmwares for the kk.

Assuming you are getting the motors to spin up, each one should be producing at least 300 grams of thrust I would think, I didn't check those motors but just as a rough guess...but even if it was 250 grams, with 6 motors that would still be 1500-1800 grams of thrust. For a 800 gram drone that...

Check your channel travel in the kk2, make sure when you throttle up that you are getting full travel (near 1900?), it is possible that your transmitter is only giving you 50% travel range on the throttle channel based on the manual esc calibration you are doing. How are you doing the manual...
