28 size 4 pole motors?

[nativepaul]

minicatracing is the sole USofA importer for Tenshock Racing products and he does not carry those motors in stock, but he might well be willing to add one to is next order for you.

Not exactly what you are after but have you considered a 6 pole motor? how long or what weight are you after? What KV?
Mega Motors make some very good 28mm 6 pole motors which are the 16 series (16mm diameter rotor) available in numerous lengths from the 48gram 16/7/x (where x= the number of turns) with a 7mm long rotor to the 170gram 16/40/x with a 40mm long rotor they are very popular with EDF and boat guys and many of the popular winds are available from stock in the states. Mega are willing to do custom winds if the KV you are after is not a production item.

Or HETrc which are clones of the Mega Motors but I have used both and the HETs are very good as well, cheaper but available in a much smaller range of sizes and KVs.
