kk2.1

Hi I am setting up a kk2.1.5 on my hex rotor. Turnigy 9x transmitter and receiver stock kk2.1.5 from hobbyking stock turnigy plush 30amp esc multistar 2213-935 motors The problem I'm having is that no matter what I do I cant get the throttle to zero in the receiver test, the lowest it goes...

Hey there, I'm building a quadcopter using a KK2.1 board and would like it if I could have a link on how to program it. I have not found very good ones so far. Thanks!

Would love to see the KK Mini Review for multirotors and for planes. I know there are multiple versions of firmware for these boards(same as the KK 2.1.5) and would like to see a video explaining some of the options as well(OpenAero, OpenAeroVTOL etc). P.S. Thanks for taking the time to check...

hello, i was wondering what your p and i gains and limits are for the flitetest electrohub for FPV. and also when i have the auto level off and i fly it still is in half auto level because the quad twitches a little bit, like when i come to a stop now i am using a kk2.1 with one of the latest...

Hey there! I've just completed my Q450 quadcopter build with 25A SimonK Escs, SunnySky 920kv motors and a KK2.1 flight controller. When trying to obtain a hover, the thing just falls over. I think i've might found the error, but don't know which component is the faulty one. When i hold the...

Alright, so I got a KK2.1 Hardcase and I put it on the HK x650f quad frame with AQ2810-750kv motors, HK BlueSeries 30A escs, 12x4.7 props. Running a 4s 4500. Getting around 15 mins hover. On stock firmware it was horrible. After upgrade there was an enormous difference, almost hands free hover...

So i have built a Tricopter. I like it, but my problem is that sometimes when i am flying, it does not fly stable and starts teetering slowly and violently. I have played with the P and I gains and limits but i dont see any change as I add or subtract numbers 10 at a time. It flys well when im...

I'm using a kk2.1 board and would like to utilize the low voltage alarm. I'm running 11.2v 2200mah batteries and am looking for alarm threshold setting recommendations. Thx Joe

I just got my kk2.1 board and have been reading that there is new and improved firmware for it and came a cross Steveis Blog. Steveis has been producing some of his own firmware and thought I ask if anyone has used it and what there thoughts on it for a Beginner and Advance User. Thank you in...

Hello :D I have a love/hate relationship going on with my Talon Tricopter. I've got it flying, tuned in etc. etc. and it seems to not have a problem until... After a bit of hovering I move off slowly for some out and back type circuits (in the fairly tight area I have been testing in behind...

Hey everyone. It's great to be getting started on these forums. I am glad to consider myself part of the community. First off, I am a total newbie at RC. Just started building my tricopter from Flitetest back during Christmas. I have had many successes and failures, but I am loving every...

Hello everyone, I am new to the RC hobby and decided to start with a tricopter. So far I have run into 2 issues. 1. I bought a potentially over kill receiver (AR12020) , and the kk2.1 does not seem to be able to read anything outputs. The only thing I could think of was the it may have a too...
