Have you tried the 9000kV outrunner sold by SydneyRCJets on your EDFs?
I was able to get about 70g thrust on a 2S, 35mm EDF. Would be awesome if this motor fits the 25mm EDF case!
This outrunner is too large to fit into the GWS 30mm EDF case. A 10.5mm motor housing would be perfect.
Rough info on the motor:
10g (including wire leads)
Mounting plate 10mm dia, screw hole-to-hole 8mm
Outrunner can 14mm
Total length 38mm
Shaft 1.5mm (threaded)
