i can't find 35Amp ESC..
I understand what C means so the multistar 5200mah * 20C can give 104A, ok but my motor specs is : Max current: 30A, so 30 * 4 = 120A is that right ?
 
Yes, you'll probably want to get a bigger battery, or more efficient motors. As for the ESCs what about 40 amp?
 
Hi mate your be good with a 20c battery , as for the props the 0.2 deg pitch between the 10x4.5 and 10x4.7 will give you loads more lift trust be I have flown on both props and the 10x4.7 really make the quad jump with the extra lift
 
Hello Tombost, AS a biginner, you have to buy some small fpv for practicing then diy quadcopter by yourself. Components of quadcopter is complex and what motors \ ESC \ propellers and battery combination will work with each other you have to know. Before you start buying parts you should have rough idea, for what purpose you want to make your quadcopter?

Hello,

First, sorry for my bad english I'm French.. I have a SYMA X5C and i want to create a "good" quadcopter to explore outside with FPV transmission and record with a mobius. It's my first setup and i don't know if this is right :
