Zmr rcx 1804 motor adapter for hobbyking diatone fpv 250 quad frame

Here it is: the zmr 1804 motor adapter. $10 shipped for a set of 4 ($14.50 Shipped international)

they are designed to fit the hobbyking fpv250 quad frame.
http://www.hobbyking.com/hobbyking/s...otor_kit_.html


design requirements achieved:
-held on by zip ties
-gives you just under 2mm of thread engagement on the screw so you don't hit the winding
-has locating features so the zip ties are only working in tensile, all shear is taken through the adapter
-use stock screws that come with the motor.


weight= 2g

PM me if you'd like a set. I can do red, black or white

wow, looks like a business strategy to me that hobbyking made the frames on purpose that they don't fit the zmr motors, they were the strongest rival against the multistar motors in the same price range.

pla, no plans for any other material.

People have claimed that pla weakens in uv light and from water. I've had a part I printed on my porch in the sun and weather for 6 months as a test. It shows no signs of weakness. Granted I'm not actually testing this, but just going by feel.

The loads are so low on the stuff that were flying that it doesn't even concern me.

Thanks for checking these out.

I have more products in the works.

JUST ordered a set of these from your store. I've got an FPV250 frame on the way as well as a set of the 1804 motors, I had *NO* idea they wouldn't fit until I stumbled on this thread. Great work!
