Hi Hobbyking bro's... :-)
I have waited over a mounth now for my orders to arrive.
I havent any word from you, into when i will be getting them, or if you have post them or not!!?
When i ordered it said that there was a 14 days backorder on both of the two things that i ordered, and its gone two over two times that.
Please let me know how it is going, i just dont know how to follow the post, someone has to teach me how one can do that...
I am affraid all i know is what other people has posted here and there, if you google it, you can find some things "" about it, but not much. I actially hope that Hobby king sends me my stoff now that it has gone over 1 mounth they should be here soon i hope, so that i could start producing some results ( motor data i mean :-) )
But i asked a Brother on Youtube, and his sujestion was not to go for the Turnigy, he had very good results with the Jeti 300Amp. and he really was very happy about it.
I have to say there are some really good Esc which can be relied on, with high charges and hard works and i have seen that some people use them on Motorbykes, bykes and even some small home made fun project gocarts. I dont know where to get them, i just know that most of them are coming from us, and a few from uk. If your research does give you any result about these esc's please let me know too.
Wish you the best of luck ....:-)
why 10 seconds? I really am happy for you,you are living my Dream right now, and i have to wait until i can get my motor so that i can start my project too. Did everything went well with your esc?
I am looking at using 4 Rotomax 150cc in a small aircraft...replacing the conventional 65HP Rotax 582.
It seems like you have done quite a bit of testing on this motor.
I am looking at the Turnigy Fatboy 300A ESC 5~15S (OPTO) speed controller and swinging a 30X10 carbon prop.
Reidar mentions 38kg thrust...can you give me your exact test setup so I can look at it. What battery and ESC are you using?
I think, a Yuneec electric motor would be better than some brushless motor build for RC planes.
Yuneec build motors up to 60kWm so they would certainely have one engine which is appropriate to your project.
Hope it helps

and thank you very much for your responses. What do you think of
Turnigy Fatboy 300A ESC 5~15S - (OPTO) ?
I will be using this motor for paragliding, so i would like to use the biggest prop i could get a way with, offcourse i will be gear it so it will be easier for this motor to turn a bigger prop. I could use your opinios very much, as i know very Little about this. It will be good for the Hobbyking, because a couple of friends of mine are waiting to see how it goes for me, so that they could buy their own motors.
Another question that i have, is what do you think about the turnigy 100cc motor the (Turnigy CA120-70 Brushless Outrunner (100cc eq)) has anyone of you has tried it, and if the 150cc is a bigger and stronger motor isnt it ?
than why the 150cc wieght is 200 grams less!? it makes me nerves even thou the wieght of the motor should not be the only reason, but in the case of brushless motors the wieght says alot doesnt it!?
Hello, I'm using this motor to power a fullsize hangglider. It is superb. Lifting me and hangglider total weight 100 kg up to 600 meter for thermal flying. Swinging a 30x10 prop, ESC Turnigy dlux 250, 4 pcs of Zippy 7 cell 5800mAh. Really amazed by the power in this thing. It is not a toy, it's an aircraft engine. The "Beast from the East" Brg Reidar Berntsen, Norway
I need your help Guys. I have just ordered this motor, and for what i am reading here the Esc. that Hobbyking are selling are just not good enough for these motors!?
So my question is where cai i buy a Esc that is reliable, because its very important to have a very reliable esc for what i will use it for.
My second question is hobbyking says that this motor can be used as a 150cc and the other motor they have which has nearly the same Price and abet heavier is a 110 cc replacement. Which one of these two motors give you more power this one or the Turnigy CA120-70 Brushless Outrunner
Hello, I can recommend the Turnigy dlux 250 Ampere for this motor when used with 14 cell. It is reliable and robust. We did quite a bit of ground motor testing before flying the fullscale hangglider. I think if You want to be on the safe side it is a matter of measuring the current with the propeller choises. Be sure that the motor does not hit more than 190 ampere at full nominal speed. It is pretty easy to get the prop on the heavy side and current to high. Then throttling down is not a good solution, current is too high. Even with a small 25x15 wooden prop at 150 ampere max the beast pulls way over 25 kg thrust. With a 200 amp prop 30x10 it pulls more than 38 kg and what kind of model airplane needs that ?
38kg of thrust at 190amps was very entertaining. With a wattmeter I could only achieve 17KG of thrust with 300amp JETI ESC, 13S lipo (7s 6s)' prop 3020 wood, at 190amp. What prop and what othet setup did you do? Really curious. Thanks
To get huge thrust at low airspeed You have to go big diameter low pitch propeller. 13 cell lipo is useless bcs You are not using the full rpm and kW potential of the motor. Go 14 cell and calculate big diameter prop tipspeed lower than speed of sound. Low pitch big dameter prop pitch You can basically get any thrust but speed window will be extremely narrow. I get this props by cutting down the biggest carbon props
Hello, I installed this with Fatboy 300amp and found no problem at all, I just set the maximum and minimal trotle with a servo tester, and there you have it. Oh and I use 3amp BEC with 2s lipo, the regular one
...for a PG a geared down 1:2 or 1:3 solution would help a lot. For a hangglider motorglider solution that is not necessarry since my Wills Wing U2 160 requires only 12 kg thrust to stay aloft with me onboard. And no flatland start, only mountain launch.
I just tested with 300a esc,lipo 13s,prop 3212 the result is at 50% throttle the wattmeter showed about 200amp current and tachometer at 3000rpm,and the motor shutoff after that showed too large prop. So dont use 3212 and 13s.
Now I will test with 3012 (better with 3010 but not available at this time) and 13s* then 2810 and 14s* I will let you know by future update.
Field test with 3212 13s Paramotor Eleftric (I weight 75kg,the paramotor 20kg) : althou the motor will shutoff after a few seconds,I manage to get off the ground 1 meter height for a few seconds and then landed safely.
Thanks for reading.
Finally achieved 20KG of static thrust with this motor, but I think the Fatboy 300amp ESC burnt because the throttle response was not smooth (will change with another same amp ESC but different brand). Lipo 13S nanotech 5000mah (6S 7S) the highest C possible. And the key is the biggest but lighest prop as possible, I use specialized wood prop 3020 which only weight 197gram compare to carbon (same size) which weight 300gram . Do not exceed 200amp with ESC Turnigy Fatboy 300amp,it might get burned)...IMHO...LOL
Hunting for high thrust with too low voltage with this highspeed motor will draw high current... Regarding prop You should for a PG swing something like 34x6 at the motor full nominal rpm at 55 volts. Tapering and cut down the prop tips until current and rpm are precisely where this beast develops 9,8 kW. Remember that the 10 kW german motor used in the nanotrikes are developing 60 kg thrust at same voltage and ampere just bcs it is geared down and has precicely matched prop.
Guys, a multicopter can also NEVER be compared to a normal copter. A normal copter has larger blades than a Turnigy motor will ever be able to operate, thus able to provide a lot more lift. Adding x amount of motors to get to the same amount of HP compared a lightweight helicopter also is bad math and in RL application will not work. For one a multicopter relatively needs more power to keep balanced.
A tip in case you're lifting persons : use more than 6 motors, in case one will fail, safety first if you're 'playing' with lives.
If you are refering to a multicopter, let me give you a link that is almost crucial in building any kind of custom aircraft.
*******adamone.rchomepage****/calc_thrust .htm (in case link is obscured Google 'adamone calculate trust', first result.)
Lifting 200kg requires 1000Kg of trust, but this is not only for lifting the weight, it's also to keep your aircraft stabile. Is it possible with these Turnigy motors ? Probably if you use enough of them, but then you always return to the problem of batteries vs flight time. Turnigy motors can only handle up to a certain size prop (~32-34"), if the prop is too big, it will kill your motor. To my knowledge the Hacker electro motor is the only motor that provides a little bit more than the Turnigy (rated at 150-200cc combustion). Still your craft would need 8-12 motors, at least, to carry that kind of load. 12motors * 2.5kg/bat.pack = 25kg total for 1 pack/motor. See where this is going ? Needs more lift, bigger blades,more electricity to achieve full flight capabilities to sustain a 30 minute flight. You can either solve this by using an airfoil design for horizontal flight OR end up with a bigger motor, bigger blades, a custom generator and 15K Euro worth of Lipo batteries.
Or to put it simple : the more you're trying to lift, the more costs will rise exponentially.
Max, if you look at my other answer, you'll see that you are way off in terms of lifting force. With an 8 lb/sq ft disk loading you can lift about 125 lbs with 13.1 HP. To lift 200 Kg, you only need about 46 HP. Human powered craft have to get the disk loading much lower so that they can lift with less HP which is why they use a quad configuration.
Without knowing the actual efficiency, this motor is rated at 9800 watts or 9.8 kW. 9.8 / 0.7457 = 13.1 HP.
The Mosquito ultralight helicopter, it has a 9 lb/sq ft disk loading and needs 64 HP to lift 550 lbs. With this configuration, you could lift 112 lbs with 13.1 HP.
The Ultrasport 254 has an 8 lb disk loading and needs 55 HP to lift 527 lbs. With this configuration, you could lift 125 lbs.
Depending on the motor's efficiency, you could possibly swap the Ultrasport's Hirth 2703 engine with four of the Turnigy 150cc. Of course, the weight of the four motors and batteries would have to equal the weight of the Hirth engine and gasoline which would be around 110 lbs.
So, the answer to your question is, yes, with an equivalent configuration.
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.
apologise for my ingles, I speak spanish and I am learning english too.
Hello Max, i think about a same project for a while.
There is a ULM with 2 CA120 : *******vehiculeelectriqueduf****/article_vehicule_el ectrique.php?billet=45 (french link).
Multicopter would be great, but e-volo project use another motor with less power (*******en.wikipedia****/wiki/E-volo_VC2 for this model, 2kw ?).
The better aircraft for me : *******acecraftusa****/archive/index.html
Electric version may be fantastic... spec : 40hp, 3 CA120, and huge amount of battery. And... experimented mechanical (to couple motors and manly for yaw).
Max, start by studying the video clip on Gizmag**** for the three-man German team that managed first human-liftoff with an all-electric multi-copter. In the video, you can almost discern the LiPo pack sizing... almost. They had some smart things, like a gym-style sit-on blow up ball for 'seat' and 'landing suspension'.
Even when the human pilot 'took off' he was actually controlling the craft via R/C, as most flights had been tethered flights, with non-human loads.
Your dream of longer flight-time might be difficult, as each kg you add of battery means you need more 'lift', so larger motors/rotors.
I'd speak to the German trio, as they may share some info, as it was for a uni project, to save you repeating their year of experimentation to get it right.
Hi, I recently lost my job and, among other things, I plan to invest some time in a hobby that I have in a while, the helicopters. I am fascinated by quadcopter, and I keep thinking about the idea of **developing one that I can ride. It may seem really crazy, but after meeting the e-volo project, has done more to encourage me.
Could anyone tell me a good book, a good article on the Internet or forum for how to calculate the number of HP, helices size, number of battery types to raise 200 kg?
A priori, I think it would be enough with 160 HP (8 CA 120-70). I think one of the big keys is to know the weight of the batteries and the flying duracció*n (estimated min. 30 minutes, maximum 45).
What if running this motor with 12S lipo, instead of recommended 14S? Has anybody done this before? I assume it should effect the output power & possibly the prop size but don't just want to guess? Thanks for any input.
Running any brushless motor on a lower voltage is fine with just a decrease in top speed, however the lower the voltage, the higher the current draw for a given power output, so watch out you don't cook the motor input wires.
*wellmanite, first of all thank you for your help.
i am just thinking to deliver enough power to pull two people on it.
i would like to reach a tempo between 10-15 mph.
its just theoretical. so dont worry about if its going to work :)
i just want to know what i would need to operate it properly.
but the inrunner are a good choice, they are small and powerful though.
giving me some more space to do a bit design
