Rimfire motors?

I was looking at the line of rimfire motors Tower has and they are priced right but not much info or specs. I looking at the Rimfire 28-30-950 Outrunner because it sounds about right for my 16 oz 3d flat foamie. Anyone with experience with these motors?

Great Planes has a bit more info on these than Tower.

Since the new line of Rimfires are just released, there is not much user experience yet. I can't believe all the models they are making. Seems like overkill. Tower may be the only vendor that carries the whole line.

Beware the 4555 - I believe there is a typo - with 10A max constant @ 11.1v its hard to get 150W max continuous - I think that should read "120W".

Great planes rimfire is from GSmodels ,. They are one of the earliest of hobby use motors maker in China. I was introduced to them because one of my customers (nothing to do with our hobby but a telecom maker) is located next to them.
I have used (still got one or two working, but brushed ESC is too expensive for me to use them now ) their rare earth metals 05 motors. And every year Sept time (Mid-Autumn festival )when I visit my customer , I always go there to buy sth., the boss old man is a nice guy to talk to. and I like their outrunners most for their 'original design' of secure method to magnets, they spend efforts to mill /route? slots into the rotation cans so that the magnets will hardly thrown away. And I still have several pcs of their inrunners mated to different gear boxes.
I killed a 2830, kv~1200 at ~300w and then a 4250 outrunner burnt at 1600w! I am so lucky to find them for my ignorant tests in early e flight days .I wish I have known him earlier, that may help me saved 2 hackers B50s gear motors.
I just bought two of their bigger outrunners weeks ago, the 5065 and a 6362, the latter has been run at 2200-2400W for 60-83 secs cont, will be used (abused) it to a Adrenaline 120. They shown me a 80cm dia outrunner , which is prep for a toy show in peking they said,...
