Designed as a 100cc gas engine replacement, this motor is a great alternative for 3D and sport planes up to 35lbs!
The motor is very well built with strong mounts, end bell and a concentric double bearings at the rear to support large propellers and rotating can, especially during hard 3D flight.
This motor is very well engineered and of the highest quality. The factory can produce only a limited number of these motors per month due to the increased time in balancing and machining such a large object.
Thanks for contacting the HobbyKing Support Team.
Rotomax 150cc offering is bigger than the CA120, it is lighter though. CA is a tad more advanced motor, it is precisely balanced and has over sized bearings and more material throughout to add durability.
Power wise the 120 is actually more powerful as it allows use of up to 70volt packs that is 16s, while 150cc will go up to 14S.
Both motors are rated at near 200A continuous power, that for 150CC is 10 000W and for 120- 13 000W.
I hope this info is helpful,
have a great day and best of luck with your upcoming project!
Thanks for emailing support.

I bout the Rotomax 150cc which wieghts around 2.5 kg. and this motor is around 2.7 kg. and this motor is more expensive than the one i bout, why?
If the rotomax 150cc is the better and stronger motor then it should cost more, shouldnt it? specially when they both are from one Company. The problem is i am not shore that i maybe should have bout the 100cc more expensive one, because in the picture it seems that it has a better quvality!? Does anyone knows about these two motors...?
Nooflyer are you asking or telling us HAHA. It does say in the LISTING: Designed as a 100cc gas engine replacement. So I guess you are correct. But only God know where life comes from. This motor is just part of Gods (HobbyKings) handy work. She is so beautiful.
Hi I am Eli, Please is there anything that can help me? Turnigy CA120 70 Brushless And told me that he also sensorsless. I used to buy the controller "Big Pat 300 and very disappointed that he cut after 2 seconds if 15 cells. Although it should work with 15 cells, that actually 15 cells giving about :60-62 volts and runs up to 55.5 volts, so it cuts. Less cells, means less power, and for me it's not enough. Now I have two questions:1 Is there anyone who knows if is possible to connect sensors to this motor? If so, how? 2 Does anyone know of a controller bigger, stronger, more professional that can run higher volts? As 70-72 volts?. I use this engine for paragliding,So it is not very important to be light weight. If anyone can help? I am very happy and I thank him in advance. Thank you.Eli
hi, I am interested in this product, because I build a e-bike, but i don't know which speed control a need use, batteries and more, my knowledge to motors and lipo batteries is poor. I need help. please help, give me information.
if interested in a powerful or deadly controller for this motor for any use like ebike,huge or giant rc plane,boat,scooter etc send me and email brightfranklin26*yahoo**** i will be glad to give you a link to your desired controller
OK, 9s sounds good but I heard that the motor or esc could blow out as something about the esc not being able to do a very good job controlling the motor at slow speeds for some reason. I don't want to risk blowing out such an expensive motor.
I bought 2 of this and 2 fatboy 300A esc to assemble in a goat soarer that i´*m builting. In fact i´*m a little tired of just watch the flights... any help with information about best combinations for a hard constant push will be accepted
This is a 20HP motor. If you have eight of them for a large octocopter, you will have 160HP.
The Robinson R22 helicopter (the real thing) runs on a 160HP engine.
Is this motor stronger than the Hacker A200-8?
If anyone needs one with hall sensors, I have it. It's the original version bought here a year or so back.
Installed hall sensors, but never got to installing the motor to my bike. Contact me for details at email: sarunas at circuit dot LT.
given the proper power setup could i put this motor in a go cart or pocket bike like vehicle for me to ride? have been thinking about this for a while? if so what would i need (ESC, Lipos, bullet connectors, RX/TX?) cheers
You can use on a bike or cart, just use a car controller (ESC). They manage the peak current to remove cogging and prevent over-current (letting the smoke out of your ESC). Car controllers are commonly available 6S (24V). I my experience 24V is significant when backed by over 100 amps and 'huge' electric torque. 24V x 100A = 2400W which due to a flat torque curve is equivalent to 7500W or 10hp. Cheers Noss
What happened to the price?? It also looks different than the last version and not just the color, the front of the motor is different. What else is different? The Turnigy 100cc motor looks more like the old CA120-70.
Hello James. I'm working on the same project too (paratrike CA120-70 FatBoy) ... I use bullistorm 10000mAH 12S on 4P. it should give me 10 minutes. What prop you use ? Full throtle need on take off only, at cruising only need 50% to 75% throtle ... please add me on facebook as christoffel moekoe
My one of these motors does not work. It just makes a little 'grunt' when I start to increase the throttle and then the esc resets. About 1 in 20 trys it will actually start. It has a Fatboy and then 15cell 5000mah x 2 Any ideas?
You could have these things going on:
1. Reconnect your motor cables in different ESC cable plugs (right outside cable to middle,etc.}
2. Check Tx servo direction. ESC don't like reverse servo or they work in reverse depending on the ESC
3. Make sure the ESC Xcvr plug is in correctly
Best quality in build and look I've seen at hobbyking so far. Mine has a no load current of 10A at 13.8V and 22A at 44V. Almost 1kW losses without doing any work. I'll try to use a 36V 400A controller which needs hall sensors.

I am planning to buy, but 1-2 months later. First, I should see the results of the tests, and I must look for ESC and bat. for this motor.

bought four of these for my quadrocopter but it killed the battery and the roof of my shed on first run. luckily noone was injured.
