If you can get seme help even for your 1st 2 / 3 flights, try using more advanced planes on FMS that are more sensitive, practise trimming FMS without looking at the tabs and if you do go for your 1st flight on your own find somewhere you think is twice the size you think is neccassary, make sure there is NO wind for your maiden and don't try and trim it until you're way up high which will probably be double the height you think you should be flying at and the keep it high it gives you time to correct mistakes !!!
Put a timer on so you know how long before the battery goes, you don't want to be landing for your 1st time ever with no power and try a couple of practise landings but pull up before you actually land !!!!
You're 1st flight isn't about pushing it to the limit and staying up for as long as you can and pushing the battery till it's flat it's about making sure the plane survives to make a second flight
