Hi Gaurav , Thanks for the suggestions !
I will not be flying alone and someone with a lot of experience with nightflying will be with me so I that way i am sure i wont lose my plane incase i do lose oreintation .
The lights on top of the wing do help since when banking , the lights wont be visable and there is a risk of losing sight.
As far as the battery is concerned , I will be using a 2s for the lights , which is a separate pack .
There are lights at the bottom of the plane too , i will just add the tags .
The lights at the belly are protected by clear tape so they are safe , i suppose ?
They are just too bright on a 3s battery , blinding !
@sun like star - Thanks for the suggestions , will be careful
