Hey Like minds.. Lol .. I am an Electrical Engineer too .. working for samsung.
...
but anywaz.. Yes, you have it just right sir, Esc should be bigger. Seen threads of Castle Ice 12A ESC on the 130x? Just the reason as you listed above. Many people are going with that mod.. not me. I dont need it right now, but for longetivity like you said PLUS for the governor feature..
now.. if the battery is HOT.. thats bad.. if its warm.. Thats normal.. TWO things blade engineers messed up on.. ESC.. you will see a ton of people burning a specific FET on the board and bunch of people offering surface soldering services to replace it.. and second was the connector. And thats why you'll see a ton of people changing theirs out too
heehee..
WEll to be honest.. third.. the tail servo..
Anywaz.. I wouldnt worry about your ESC much till you smack this bird hard like hard tic tocs or smack piro flips or pitch pumps.. and fast rainbows with hard stops.. thats gonna tax your esc and motor a LOT. but apart from that.. you are GOOD for now.
Now yeah if you are willing to you could change all that out and make this bird an untouchable beast .. where the electronics wont fail.. lol or just leave it as is.. DS35 is a great mod too.. definitely recommended.
I personally havent done lab tests on current draw. I donot take this as seriously.. I go by the feel of the components in flight... LOL i got too much to do on my bigger helis lol for worrying about this.. so let other people do the tests and I just simply take the results and test them out.. I have read a bunch on this thats why I did it.. and thenwith mods like this, if I feel like its good.. I Promote it.. If i dont I let it slip.. I didnt spend time on it.
And with this battery thing , I really only know by the feel of the bird. I had the same exact thing happen to me when I went BL on my mcpx. I went to a better connector and Man it was noticeable..
Hyperions dont pay me..
so I cant say that the product you have wasnt crap.. very well might be haha.. only you know. Turnigies are great batteries too.. so are pulse 450's .. try it all out.. see which one you like.. tell us
and then try another connector.. and see if that makes it feel better
Phew.. Rant.. been alone at work today hahahahahhahhahahah
