I void warranties
What would be approximately the maximum capacity of a 3s pack a model built with these could carry? I realize they're for super tiny build which I have no exp with but I'm looking at building either a halo 90 or a Owl mini (88mm) and trying to figure out if I could run these of should go with something like an 1105 or even 13xx instead

CK: You might want to search threads for the Halo and Owl for motor recommendations. The 1102 are best suited for extremely light builds. IMO, this would disqualify any frame with heavy enclosed props, e.g. the two you mention. Only exception would be the RS-90, for which RotorX designed the original RX1102 7800KV motors.

85 watts? Is that for real? At 2S that's 10 amps.

100mm quad motors are massive!
100 mm = 10 cm = 3.93701 inches
