The bushplane I'm trying to model was often equipped with a 3-bladed prop. Planning to use 4s battery and wondering if a 13x6 or 13x7 3-blade sounds right? Expect the model to come in around 8-9 pounds.
6s with 14x7 will pull a 8-9 pound plane well but if you put a bigger prop on it. it will get hot if you need a bigger prop look at the a or b version of this motor if a 14" is good then this is the motor you want.
Wondering if this motor would have enough grunt to haul a 10lb scale model of a Noorduyn Norseman(bushplane) I'm looking for scale performance and the power to operate on floats. Probably will try it on 6S and looking for prop recommendations.
I think the power would suffice for a 10lb bushplane but you would not have that much margin left over. For this kind of plane I would recommend a big prop with low pitch so as to get much thrust at low speeds, large prop also entails the benefit of high efficiency. I do know that this engine together with 6s and a 13x6 prop gives 4,2 kg of thrust so perhaps you should use a 14x6-7 or 15x5-6 in order to get vertical performance. One can always but extra strain on the equipment to get more power but it will limit lifetime more.
Does someone knows how much kg of thrust this engine ofers with a 9x7 propeller and pack of 3 or 4 cells?
Thanks a lot...
Olá* a todos,
Alguem sabe me dizer quantos kg de potê*ncia este motor oferece com uma hé*lice 9x7 e bateria de 3 ou 4 celulas?
This motor is capable of providing a lot of power if you wish it to.For your trainer you need around 600 watts,so this motor with a 4cell lipoly battery will draw 41amps and give 600 watts of power,a 4000mah battery will last just under 6mins flat out or a 5000mah will last just over 7mins flat out.
the hein should weight about 3.2-3.5 kg max using a 4s 4500mah bat.. i have been looking at the turnigy 50-50 600kv 1500w/g60 500kv. i have currently flew it with the g46 550kv with a 15X10,but i think it need more power.so we need something that spins more than 14.8x550kv with a 15 x 10..right? i try to contact u on other discussion.hope u get this one. thanks
Hello Arnaudd,on 4 cells you will struggle to get much more power,looked at this motor and the G46 and the results are very similiar.I did find though that the 15x10 does not bring out the best in either of these motors,it is a bit co****,your present motor with a 16x8 improves the watts slightly by about 25 but the thrust increases quite a bit by over a 1000g,would give that a try and see how you go.
14*8 is too much, I tried it with 12*6 and it gets hot and amps was over 65A, with 13*4 temp. was fine and amps 55A, but I have it for 60" wingspan 3D, so I dont know if it does enough power for 72", I think it can be possible if weight of your plane is max around 2.5kg
Well i got the motor today and out of the box it sounded bad just spinning it by hand. In the plane it was horrible. Ran a test anyway thinking it would blow up on 7s with a MAS 12x6. Held together and my specs were 58amps and 1320watts. As i knew they would be, any calc program is always wrong. Real world tests are never the same as a calc. Oh did i put a period after that? Yup, just checking. POS motor. Can magnets are hitting the commutator. This is the 3rd air motor i have had problems with but the first 2 were loose magnets after first runup. No more for me.
Guys, the adapter that lets you mount this motor in the other direction seems to have the wrong size screw threads cut. It's supposed to be M8, but it's clearly not because none of my M8 nuts fit. The collet adaptor for the shaft is fine.
Does anyone know what the correct size thread is?
Hi rayonnair, I too had the same problem and no way is there a nut that will fit this thread. In total desparation I got a flat file and took the edge of the thread until i could get the supplied nt to screww on,it now works fine. H>K> please check these things during production.
Hi JOHN R> again i have a better solution to this problem seeing thatH.K. do not stock parts any more, all it involves is to turn the shaft that the nut won't fit down to six mm and use the adaptor that normally goes on the other end. hop this helps/
from JOHN R. I have come up with the ultimate fix for this problem< put the boss that the shaft extends from in a lathe turn the threaded shaft down to six mm and fit the prop drive with the black spinner nut that will clamp onto the shaft problem fixed. I know I have done this allready. Regards from JOHN R.
Since it delivers 1600W it is quite similar to a 60 size glow engine, but due to the fact that it is an electric engine it can deliver the power at a lower rpm with better efficieny in combination with the right prop. Furthermore you can burst it beyond 1600W, lets say 2kW for a few seconds so it is probably closer to a 75 size glow engine.
It's actually quite hard to get 1600W unless you use 6s lipos and a small prop. I am running WOT 75A on my setup (13x8 prop 5s lipo)Battery is around 30deg C after an 8 minute flight. Mind you, I'm hardly ever WOT.
Yea but wouldn't it be even easier to reach 1600W using 8s lipos!? A smaller prop results in higher rpm, which in turn results in higher emf and lower internal voltage and hence also lower current and lower effect, the opposite of what you claim. Apart from that I would like to thank you for the information you supplied by sharing your set up data.
Bloody oath it would reach it on 8s easily, what about the voltage rating of the motor? I didn't claim anything other than "I'm hardly ever WOT". What was my claim..so I can understand the "opposite" statement?
Sry, it came out wrong, I am Swedish, but what I was refering to was your statement about reaching 1600W using a small prop. With a given, and high, voltage one could approach 1600W from above, from lets say 1800W, using a smaller prop, but I was assuming that you meant approaching 1600W from a lower effect, in which case a bigger prop would solve the problem. Maybe I misinterpreted you...
Just to give others ideas: On 4s lipo with 13*6 prop, P=650w, I=40A. I've since changed to 13*8 prop for slightly more power and will try 14x6 and 15x6 next. The plane is Extreme Flight 58" extra 300. I wanted to reuse the batteries I already have rather than going for a 5s setup. Chris
On 13x8 prop, 5S 3000MaH zippies I get 8-10 minutes very useable flights. Current is at top end for the motor - 60a WOT but it is dragging the 58" Extra around easily at 1/2 throttle. Battery takes just under 2A to fully charge. Don't think I'll make any other changes, I'm satisfied now.
Yes I have thought about getting the B series as its kv is lower, however its max amp is a bit lower, 55A instead of 60A, and the max effect is also lower. Rest assure I will take your worries into consideration, thank you! I know that some managed to run the old 600kv version at 100 amps which by far will meet my power demands, it will be interesting to see how many amps people can put into the current 600kv version.
ok im fairly new to electric but i have this motor and now you are all making me want to run some tests! but what you all are saying is not making much sence to me 1st 8s is the only battery that is going to get you to 1600w and 12 and 13" prop sounds to small 4 this thing i dont think its going to get loaded up at all with a 13" prop i would think it would need at least 14" with a lower cell battery. i plan on running a 6s 5000ma battery and 70 or 80 amp speed controll.
i still do not have a meter but have it in a 55" pitts-12 over 7.lbs 6s 14x7 prop. prop looks way small on the plane but moter pulls it around like a rag doll unlim verticle. cool to the touch after flight.
The KV of this motor is way too high for that prop and you would end up pulling current way above the rating. Go for the lower KV version and you should be right. Or go for a higher current rated motor. Chris
1 thumbs up!
I hhaven't tried yet but as it came the rear bearing is shot, sounds like they run out of balls and put stones in it. That's a shame, it needs replacing so I have to get it out and meassure to be able to buy one the same size.

Motor muito bom, instalado no yak-54 para motor 60 glow, com este motor Turnigy L5055C-700 Brushless Outrunner 700 kv bateria 6s 30C 5000Mha hélice 15 X 6 esc 80....ficou show.
This is a great motor to convert many 40 size glow trainers into electric. Strong and can handle easy 5/6 pound airplane. Should use 4 cell battery or up with sseperate BEC

This motor is just amazing! I havent flown it yet, just tried at home. With 6S bat. and APC 12x6" prop. it makes around 1400W 65A and motor gets hot, but with APC 13x4" prop. it makes around 1200W, 55A, temp. is fine. Response on throttle is very good. I cant wait for first fly with it in my 60" Diablotin.
