As they say, "If the shoe fits, wear it"
Hello @Carmine_RC. @Benedikt is probably sleeping now as he does that sometimes This is his night over there in Australia. The AF 5v side USB that he is selling are suitable for any build of a brushed quadcopter. The 8.5mm motors are best in my opinion as far as what size motor I would choose and personally I only have one or two that have smaller motors. For the most part my brushed builds feature the 0820-15 motors and they are very good for these builds. If you want to tour the MMW site you can find it here https://micro-motor-warehouse.com/ Also besides being able to parouse the various offerings there you will also find information that can help you with the build and links to other places under the contact us link on the site. For my brushed builds I typically keep it simple. X style frame either carbon fiber or polycarbonate, printed frames are alright but seem to be weak and break easier, motors, a dsmx or dsm2 satellite receiver, props ( I really like the parrots), and lastly a battery like the 480mah mylipo or something similar usually up to a 750mah. Lighter batteries will give you a better punch, the 700mah are usually a few grams heavier than the 480mah so they don't bog down the quad as much. If you are looking to do an FPV micro then the easiest is to buy an all in one camera Vtx but you would also need the rest of the gear, Rx, monitor or goggles. If you want to really explore all of it and make some friends there are also a few FaceBook groups that are dedicated to all this. This one is the custom built brushed micro/nano multirotor group run by John Tivet who is the US distributor for MMW: https://www.facebook.com/groups/custommicroflyer/
and the AW FC Fan Club which specifically is geared towards Alien FC both the original AlienWii and the new open source AlienFlight FC: https://www.facebook.com/groups/AlienWii/
If you would like more info plus a bunch of friendly helpers that will guide you along come join the groups and introduce yourself, there are always folks looking to help. This also is a good place to be and there are plenty here as well that just want to pass on the knowledge. Hopefully this will help you out while Benedikt is taking a nap Welcome to the party as he says.
