Great value from DYS. The 1806 size is comparable to 2204 - smaller diameter but taller. Motor performance is close to the 2204 size and a touch lighter at 24g with prop adapter and 14cm of silicone wire. Wires can be cut at any point (no enamelled wires to deal with). These motors use NSK bearings and are very nicely built - a great choice if you're looking to save a little money without completely sacrificing manufacturing quality.
Comes with bolt-on prop adapter - 5mm shaft
also includes three 2mm male bullet connectors and heat shrink
Motor mounts are spaced 16x12 using M2
Spare parts available here
IMPORTANT NOTE - the prop adapter should be secured with the SHORT screws. The long screws are for motor mounting and will hit the motor windings if used on your prop adapter and instantly ruin your motor!
Canadian customers - please note that any motor requires shipping via Expedited Parcel. There's a bug in the shipping system that doesn't pull this up automatically. If you see "Canada Post lettermail" as an option you'll need to choose the other, more expensive option that corresponds to your province to get Expedited Parcel service. Sorry about that!
