Default Rage 4928 questions

Hey guys, I'm really curious to try out the new rage motor but I have a few questions. First of all, it's spec'd at 530 grams which seems extremely light for the size of motor and why I'm interested in it. Can anyone confirm this weight? Also the power specs are VERY impressive. Claims to make as much power as other big motors like X nova 4535 but at 100 grams lighter. If the ratings are true, it should at least easily stomp the performance of any 4530. Can anyone give their opinion on the power of this motor vs others like a 4530? If power rating and weight specs are accurate, this motor is a no brainer choice. Any opinions appreciated!

I can tell you it is a beast. Watch any new video of Henrik Clausen.

If you want to go extreme try to get the cs version.

Thanks sebastion. I ordered the rage motor this morning. I'll be running it on 14s in my protos. I'm sure it won't disappoint. If it makes just a bit more power than a 4525, I'll be happy. Not sure how you guys built such a big motor at 530 grams, that is very impressive.

I was trying to figure out what Sebastian meant by "cs version" and found this:

https://www.mttec.de/RAGE-SZ4928-CS-...12-14S-Motor_1

I hear Copper Doc wound motors are pretty insane! The weight on that is listed as 570g, which you'd expect assuming they went with thicker wire and higher fill. Rated at 7000/14000W!

Just wanted to come back and give my feedback on this motor. I first tried it in my protos 700. It was unboggable power which doesn't surprise me. Doesn't really say much since pretty much anything larger than a 4525 will give basically unlimited power for a 700 flying 3d. To better gauge the motors performance, I decided to try it in my protos 770 on 14s. Im pretty blown away by this 530 gram motor. I'm running almost 14 degrees of pitch and 2050 head speed on 760mm blades and this motor blasted right throogh no issue at all. I normally run an X nova 4535 that weighs 620 grams in my 770. The rage motor made at least as much power and it's 90g lighter. For sure blows away any 4530 motor and weighs less. Very impressive! Easily more than enough power in a 700 even for the most aggressive pilot, and still excellent power in a 770. Might sell my 4535 now

Thanks for the feedback quinn. Can you gauge the motor's efficiency as it translates to flight times? What about temps? Does it get hot after a flight or does it run cooler than a, say Scorpion?

Flight time was about the same as my 4535. Hard to gauge temp since it was only 60F outside. Motor was pretty warm, I imagine it would be hotter during summer, but I never worry about motor temp too much as long as it's within a safe range. I've ran scorpions that were too hot to touch for thousands of flights without issue so I usually don't consider it an important factor. The rage motor is very light for its size. Less mass in the stator to transfer heat into the airframe so it may feel hotter to the touch than other motors. I would say my 90g heavier xnova 4535 felt cooler when touching the can, but I don't see it as a problem. It's definitely not running hot enough to affect the magnets or winding.
The efficiency comparison I observed was for flights running at max performance for the whole duration. At lower head speeds I suspect the rage may have an advantage. The larger stator diameter should be able to deliver torque with lower amp spikes than the 45mm xnova. I'll try a couple flights at moderate head speed and note the difference

Yep, it performs awesome in can't tell the difference to my scorpion. It's a nice motor...I now have 2 of these.

Thanks for taking the time to give your feedback Quinn.
