Yes, both plug into any open port on your RX. This keeps the voltage the same while doubling your mah. Two 2200mah become 4400mah! By using two ports, you have added protection should one of the batteries fail.
I dont think that's right. The 2 x 2200mah's only become 4400mah if you join them in parallel. All you are doing by plugging each pack into two separate rx ports is applying two separate battery packs of whatever voltage and 220mah so the rx sees them as that and nothing else. They arent in series nor parallel so you dont see an increase in voltage (series) or increase in ampage (parallel). Personally, I wouldnt recommend plugging two packs separately into the rx.
How heavy is that model because i want to get my model under 5kg i am not a 3d fan but i want to do sport flying mixed with mild 3d my equipment i chose pyro 750 560kv comp kosmik 200 Mk servos tp 5000mah 7s lipos plus swaping out the aligns cnc alumium for stronger and lighter kde plus ceramic hybrid bearings from boca are lighter than abec 7 steel bearing to replace stock bearings plus shorting wires to lose a few more grams but a 14s system is overkill i wont use all that power but ile get longer flight times running 2000rpm with plenty of power because the motor is 14s lol
Sorry not true. Yes the changes in current can result in voltage peaks however the big capacitors on the ESC soak up the peaks and fill in the dips. It is best practise to keep them as short as possible though mostly due to the resistance of the cable
Adrian Chapmanlaw No mate, yes the ESC's capacitors are made to destroy the ripple, but they are made to destroy a ripple made by the length of the wire that the ESC comes with. If you extend the wires, by a lot (like this dude did) you must add capacitance or it will destroy the ESC. Take a read on this page. www.rcgroups.com/forums/showthread.php?t=952523 "If you have to lengthen the battery wires, for whatever reason, add extra electrolytic capacitors in parallel with ESC, never in series with ESC. As a rule of thumb, for every 4inch/10cm extra length/distance between battery and ESC, add an 220uF extra capacitance near the controller (electrolytic condensators, voltage the same as the capacitors already installed, low ESR type)"
This assumes that the capacitor on there is marginal, which I highly doubt. That sounds like an incredibly vague rule of thumb to me. There are just too many factors. Thinner the cable, higher impedance battery would both require bigger capacitors. I agree tho, keep em short
Adrian Chapmanlaw actually: "Using thicker wire will not help, it's mainly a wire inductance problem, not a resistance problem." Trust me on this, they make the capacitor size suited to the length of the wires. You can add some wire to it and be fine, but adding a foot like this guy did is just stupid. I have experience with this, I know what I'm saying. Just recently I had some long wires on my electric scooter, I was originally using a direct connection but then I tried another battery with a different connector and I had to add about a foot of length of adapters because I didn't have the right connector. The capacitors were insanely hot, where as originally with the short wires they were barely warm. This guy should feel his capacitors after a flight. I bet they are searing hot too.
ya to many batteries for a receiver not to mention more weight . filler plates not needed reason one more thing to remove. run your wires outside nice and neat. impressive but more work then needed. what does it take to take the canopy off? reason the wire was a pain in this build is because they were meant to run outside. now you have them close to the main gear. would not recommend building it this way. you probably added 3 or 4 hrs to this build. why have to hide all the wires or almost all of them . reason for the canopy. nice job but you crash all that extra time waisted.and you will crash!. but to each his own.
I have never seen so much detail put into wiring. Excellent job, wish I had the patience for it.
Quirky layout but looks great for servicing and that switch is a great idea, thanks. Nice work!
Isent it a risk the cables get in the way for the servohorn on your tailservo? That could cause issues under the flight.
Valid points but, I like doing the extra work to hide the wires.

just FYI, having your battery wires that long will damage your ESC over time.
