I'm thinking about building a quad or trirotor platform. Therefore I'm interested to see a list of people's configurations regarding airframe weight, motor thrust, propeller sizes, battery type etc...
Thank you.

for a quad, you need to pick one of the varables you have listed and go from there. So lets start with the airframe weight; this would be the finial wight. you want a motor/prop setup that can provide at lease 2x the thrust as the weight, more =better
for a copter of any sort the bigger the rotor disk the more thrust you can get, to a point.( just like in planes push forward to go down, pull back slightly to go up, and pull all the way back to go down)
airframe weight: as light as you can
motor thrust: as much as you can
propeller sizes: a simple static test at about 70% power and pick the one with the most thrust
battery type: Lipo
If you want to give a starting point of what you want for a finish product I could help you pick out some parts.
1.4 kg lifted by these puppies turned by these motors hooked up to this battery through these ESCs. It can barely take off at about 5 kg AUW, so I'm guessing the thrust peaks somewhere in the 50 N ballpark. It can hover at 15 amps and stay in the air for a little over 30 minutes.
