Difficult to balance, particularly on the vertical. shaft diameter is small around 3-3.5 mm - you'll need to drill them out for anything larger.

wanted to use them on a quad with Talon V2 frame on NTM prop drives 28-30A 750kv but they keep disintegrating in mid air!

Good propeller for your money! Very flexible, are not suitable for heavy-duty models!

I use them with motors - 2830 750kV, 3-cell Li-Po battery.

Great combination for 950KV brushless motors for quad copters with lots of lifting power.

Terribly unbalanced props. Managed to balanced it horisontally using almost full roll of tape, but vertically - no way! If you do not care about vibration, go for them.
