I posted my question on RCGroups, but didn't get much response. Need some advice on my tricopter build. I really want to use the low voltage alarm built into the KK2, but it looks like I need a direct source to the battery. I also want to power my Fatshark TX and tricopter all from a single battery. Currently using a 4S for the tricopter, and my Predator V2 won’t work with 4S. It only takes 2S or 3S.
Here are a few thoughts so far (for you guys to beat up):
I bought the power harness for a quad (4 outputs from 1 battery), so I currently have 1 +/- lead that isn’t being used. The other 3 +/- leads are going to the 3 ECSs (tricopter). Thinking about using the spare +/- lead to go to the KK2 board for the low voltage alarm. Will that work?
I’m not sure what the best approach is to powering the Fatshark. I could build a harness from the balance lead on the battery to power the Fatshark. I could only grab 2 cells from the 4S battery to power my fatshark TX. This would also be nice because then I can choose when to power my Fatshark TX instead of it being on all the time. I also think this would be best because it would reduce static in the video since it will be tied directly to the battery. The downside is that it will unbalance my battery during flight, and I will have to keep an eye on my flight times.
I know I cannot be the only one out there with this dilemma. What are you guys currently doing?
