I have colected some newbie questions that i made in various posts around.. maybe it helps others like me to save time....Answers from Jani and others, If you have a basic question and answer... please post.> What are the recommended batteries ( for arducopter)?- you can use basically what ever from 2200 to 4000 mAh 3S lipos. ESCs/Motors can even handle 4S. I mainly been using 2200mAh 3S LiPos on my test and fun flying, with camera (Sony Bloggie) onboard I use 2650mAh 3S LiPo's, and mostly get 9-10 mins of air time with those mAh's.-I use 2650mAh 3S when carrying Sony Bloggie onboad and getting about 10 mine of flight time. Without cam I usually use 2200mAh's. Been flying with 4400mAhs but getting "tired". And this is all with those 850kv motors that are included on full kit.> could someone please reccommend a battery charger?Bill, i have some hobbyking 5Amp chargers, IMAX C6 and few other.. they are all rather ok. One thing what is good to always have is those small battery alarms, at least you can hear them on close rang> What is the indicated radio controller and receiver to use with these quadcopter? how many channels? how about cost? someone have a sugestion?Min channel amount is 4ch. To use features better I suggest min 6ch's and to have all cameraand other zillion things that has been planned..8ch or more is not bad idea to get if you are getting your first radio now.There are great low cost 8-9ch radios available on market. I use 6chs on my setups but have 8ch radio.Is a Mode 1 or Mode 2 radio desirable for the ArduCopter?The mode depends on your preferences, arducopter can be used with any operation mode 1,2,3,4.... mode 2 is used in helicopters and is the most similar to the helicopter commands.Hi, where i can find some material explaining how these quadcopters can fly in all directions? this is a mistery for me.... if anyone can explain i will thank very much.Google is really good for looking information but in generally multirotor is really simple. You have 4 motors, 1 front, rear, left, right. If you want you quad to put it's nose down then keep engine RPM same, lower rpm to front and higher rpm to rear and it will pitch nose down. Same thing when nose up but vise versa or even left down / right down. That was really simple example how it works, in real life it needs a lot of electronics to make it flyable and steady :)One good link to start with http://en.wikipedia.org/wiki/QuadrotorSee: http://www.mikrokopter.de/ucwiki/en/Mikrokopter-Get-started#Some_theory> I want to know more about rc helis and planes...http://www.rc-airplane-world.com/rc-helicopter-controls.htmlis the TGY 9X a good radio for the price?http://rcmodelreviews.com/turnigy9xv2review.shtmlI have a TGY mode 1... how to make it mode 2?http://diydrones.com/profiles/blogs/tx-mode-1-and-2-quick-tutorial?xg_source=msg_appr_blogpost> Can i change the software in my TGY 9x radio?http://www.rcgroups.com/forums/showthread.php?t=1266162&highlight=frskyMore to come..
