At last the weather is warming up a bit, time to test the NTM 35-30 motors. The NTM 28-36 and 10x4.7 APC props gave perfectly adequate performance, but they got hot when pushed. These new motors can handle up to 32amps and come down cold after flight. They are quite a bit faster than the 750Kv motors, at 1100Kv the Graupner 10X5 e-props are spot on with a 4S battery.

That seems like a real hot-rod - very nice performance. Nice design too
Good to know. Thanks for the quick reply. Looking forward to your next video :-)
Very fast, very smooth - good work!
Nice video! It must have an insane power to weight ratio with those motors. Looks like it would be fun one to fly.
Awesome flying
Lovely stuff Richard, I'm in the market fo a quad / Tri, still deciding - great inspirational video. Cheers!
I was going to ask how much extra weight but already answered. I might check these one's out. Oh nice flying too!
Superb.
A little tip. The bearings in the NTM propdrive motors are not in any way high quality. I just had my quad drop out of the sky from around 120 meters because one of my motors threw a bearing. Thank god for trees and it came down without any damage during the controlled fall. Replacing the bearing in the motors is a cheap way to extend the lift of the motor. I only had the motor for a month before it failed.
Hello Jeremy, thanks for your helpful advice. I know the NTM bearings are not the best quality, but after a two years and an estimated 500 flights on NTM motors, I have never had one fail. I have had the bearings become rough sounding and have had to replace them. I am interested to know if the motor gave you any warning signs before it failed, was it running hot or warmer that the others, did the bearing seize and stop the motor. Any further information would help me and others to monitor the health of the NTMs and hopefully prevent another failure in flight. Thanks
nice
hello am curious how your new N TM motors are holding up. beenthinking of getting them for my 550 Quad. thanks.
hello, i can't seem to find the right motor mounts for these motors
can you tell me which one you have?
I'm building a quad using these same motors and I'm wondering how you reversed the prop shaft and mounted everything??? Nice video btw. I'm excited to get mine built
Hello, I just drilled hole in the wooden motor arm to allow the shaft to pass through, no need to reverse or change the shaft. Good luck with your build
Hello!, I read that you used a 4S battery, for this battery how many mAh and discharge constant?
4s or 3s setup?
4S
