OK, I got some good results here.
3s2p lipo pack - didn't measure voltage, but it's freshly charged.

9047 gws WOT 13Amps 7600 rpm = ~ 19oz thrust

9-7 APC 11A 7000 rpm = 25oz thrust
This was about 3/4 throttle, but I couldn't mount the motor well enough for it to be safe - it kept rotating on my makeshift stand!

Texy,

Speaking as one who has has a couple of motors "fly" right off a stand, do not continue testing until you mount much more securely!!!!!!!!!!!!!!!!!! Your esc, eyes or favorite/least favorite cat could be history in a split second.

I was careful - honest. I could tell it was moving around as the rpm's increased.
I,ve stopped now

All my previous motors have been in a gws gearbox so I,m wondering how
to stick mount it. I,ve seen cable tie wraps like the above used with epoxy,
but that would seem a bit permanent.
Komodo need to design a mount, one thinks

Texy
PS it was nice to see that my dvm measured 13amps, even though its rated to 10 only

I use two sided servo tape and three nylon tie wraps and it seems to work fine.
The servo tape keeps it from slipping etc.
But the motors I've built have a little longer tube.

Cheers Bill - that would seem to be the answer. I could see the tube twisting as I increased the throttle, but it didn't move forward. Lots of torque

Thanks for that idea. What I still have from my slowstick is the black plastic tube that was for the tail removal option, which none of us use of course.
I will modify that in the same way as above.
Cheers,
Texy

My motors arrived today. They looked very very nice. Can't wait to wind one and put it in a plane and fly it.

Sorry,
Don´t own rpm meter. Yet.
Haven´t built a teststand either so...no such data.
Flying will tell!

Checks and tests to perform BEFORE connecting your newly wound motor, ESC and batteries, may save you from frying your ESC, first message in this thread, the rest of the thread is also worthwhile reading, bookmark it:
