The only difference in terms of looks between this clone and a real Hacker C50 XL motor are the absense of 5 screws that hold on the front endbell, and the colored wires. This motor uses a screwed on front endbell like the finned feigao motors. No biggie, just have a tube of loctite of JB weld handy :) The red motor is my toasted HobbyCity 9XL for comparison.:whistle: I will give this thing a thorough workout when the weather clears up, and we'll see if its worth the $50 I paid for it, compared to a $350 true Hacker. http://www.little-bellanca.com/produ.../product_m.jpg A real Hacker C50. |
Inclement weather is NO excuse for not testing something! Don't you or someone you know have a basement or garage? :smile:
Do you have a real Hacker to test it against? It would probably be better to compare to a Feigao as well, just to see where it falls in comparison... |
It looks very nice. I plan on testing one out in my Matrix TR FRE here soon. :yes:
|
Basement? We dont have those over here, well, very rarely, and nothing large enough to be any use for testing an MT really. I could run it around the carpark I suppose, if I was gentle on the throttle, but it is still pouring with rain outside, and you know I have most of the bed cut out from my truck's shell too (let in the rain directly onto the MMM).
I cant compare this to a a real hacker (unless someone want so buy me one, lol), but I can compare it to that hobbyshitty 9XL, and the hvmaxx I had. Think I will drop the gearing a touch though from the 24/62 I was running. |
Hobbyshitty. :lol:
|
Where can one find a motor like this? Link please.
|
cool Neil that motor looks well built compared to the skinny wired xl, Look forward to your results, wouldnt mind one either iffn you like it.

Oh yes, 99% of what they sell if great, its just their own brand 'feigaos knock-offs' that should be avoided.
|
just do a review(suicideneil)of these motor if you can....i yould like to try it..but im really scrared to burn a other motor.....(ive toasted 6 xl motor las 2 month)
|
I shall indeed do a thorough test and review, and post results (given my heavier than most rig, it should be a good test that offers some headroom to other users in terms of their setups).
Just have to wait for the rain to stop, gah... |
This is the same motor lutach and I tested. Although lutach was unlucky and gets the 1/8 shaft by mistake of the seller. here is the link Alternative motor
This motor is good but it is also like feigao that easily gets hot. Hopefully Neil will gets some good runs but not the heat issues. |
Yeah, thats why I bought it really.
Feigaos are a bit naff, but going by most people, they are pretty good compared to the hobbycity versions, so hopefully these clones will turn out to be fairly good too. Even if it does grenade or melt, its still no great loss- just killing time, waiting for the 70mm Medusas. |
Haha nice one Neil. I had the same reason when I bought back then (waiting for my Neu) :lol:
I think this will perform better than those Feigao but we'll see how it goes for you :yipi: |
so do you still run this motor truckbasher?
|
Not at this point. I dont think I would prefer this over my Neu 1515/2.5d :lol: (not that I'm comparing it, I just love Neu and who wouldn't)
By the way, My E-Revo where it has been running on has been sold and I am building a new E-Revo that will run on outrunner motor. |
so is there alot of rc stores in singapore? hows the pricing on the stuff compare to us prices. seen any zippy lipos around, i believe theyre made in china.
|
Well, There are a lot of RC shop here but most of them are ON-Road, Buggy, Helis, Boat and Airplane. There are a few MT but they have it just have to wait a little longer or you can preorder from them. HPI, XRAY, and Tamiya have their distributors here so its easier to get them. Traxxas can be a bit difficult. This is why Mike and other USA shops have my loyalty.
Ohh by the way, I think this motor is coming from Macau which is why I got my in 7days..... |
Let us know how it does Neil. The factory still haven't fixed my problems. I asked for a 5mm rotor assembly and they sent me 5mm shafts. They told me they would send new motors, but nothing yet.
|
lol... I thought this thread was about the new star wars c.g. movie that came out a few days ago... :lol: ......... which by the way was not worth wasting $10 to see... :no:
Now I'm interested in these motors too. I may get one of the smaller ones for one of my TC's since the current feigao I'm using is on its way out. |
You can select the shaft size in the List of the motors now.
My 13XL Motor for my E-LST has been sent on August 1st but still hasn't arrived. But my 4900 Rhino lipos arrived last friday, though.... |
Shipping for me took 15 days, which is pretty average- yours should be turning up soon I bet, though it depends on customs sometimes. The good news is, mine came with a $10 value marked on the customs form, so no import or VAT duty to pay. :yipi:

Well, first off- damage report:
*bent front Ti bumper from high speed head on collision with concrete steps. *bent motor mount due to above. *mutilated wheelie bar from flips *partially stripped spur *tyre came unglued, repeatedly *shell ripping apart around body post holes * input gear shaft pin busted- ended days play. Unfortunately, the battery in my temp gun died before I even started running, so I had to use the finger/ spit test; yeah, I was rather unhappy about that too- blame ebay quality batts though, lol. Anyway, 1st up was the 4s2p setup, with 24/68 gearing. Topspeed was very good, same as with the hobbycity motor, and no lack of punch. Motor warmed up quite quickly, and I did need to take a cooling down break about 2/3rd through the run, at which point the lipos were reading about 4.0v, so holding their voltage well, and only really dropping quickly in the last 5-10 minutes down to 3.6v, at which point I stopped the run as they were quite warm, I'd guess about 120 going on previous experience. Motor at that point had warmed up again, around the 140-150 mark (not too hot to touch, but too hot to hold your finger on for very long). Next up was the 6s2p A123 batteries, same gearing. Much more speed and punch with this setup, but the weight of these tyres I use is a real test of how much torque a motor can produce before it starts breaking a sweat. The motor warmed up a bit quicker this time, but the power and speed I was seeing was highly impressive for such a heavy rig (13lb), so I carried on bashing for about 10 minutes before taking a break- motor was quite a bit hotter than before, I'd say about 160 or so- you could touch the motor without burning your finger, but not hold it there. I used some spit to cool the motor down quite quickly- just rub it allover the can and the temps really do drop quicky (I got my mini water pump today, will be using water cooling for sure- exotic or not, it will help alot). Once the motor was back down to a nicer 'warm' temp, I switched the 24tooth pinion for a 20toother. Top speed was a bit slower as expected, but the low end was still very impressive and wheelies were no issue at anything below about 2/3rd throttle. Temps remained quite steady this time at the upper end of the sale, say about 150-160, but no higher. Play was only stopped after one too many flips or bumps caused the pin holding the input gear to the input shaft snapped or came out- I will be tearing into the tranny tomorrow to fix that up, and to give the truck a good clean in general. Overall, I believe these motors to be not much better than a feigao, but with a few advantages: *single piece magnet, not a segmented one, so will not separate into 2 or 3 pieces that are almost impossible to re-align and re-attach to the shaft. *cheaper generally. Typical feigao cost is about $60-90 for the same XL motors, where as the smooth version of this motor is $48, the finned version being $46. In a typical 8-10lb truck, I believe these would make an ideal cheap motor, as will the smaller version for vehicles like 1/10 stadium trucks and such. No amazing low temps, but certainly equal or slightly better than a feigao. I still await the arrival of the 70mm medusas- 4 pole motors have a definate advantage over 2 pole motors in a heavy application (slower spool up time but greater torque). Video will be up tomorrow in my main Gmaxx thread- editing with MS movie maker is very simple, the but programme is highly unstable and prone to crashing/freezing up, at least on my PC anyway. Hope this helps a few people when it comes to choosing motors- nice feature is the option for a 3mm or 5mm shaft on most of these. |
Thanks Neil for you report and testing...:yes: Well done.
|
hey neil you got that vid yet seems that motor is doing okay
|
im waiting for the test results too.:whistle:thanks
|
OO.
Can you post a link to these motors? Are they available in the UK? If you don't fry it before you get your medusa would you sell it? :lol: |
Hmm, I swear I posted the video. Anyway:
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/rfzDlwtLaAU&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/rfzDlwtLaAU&hl=en&fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object> My advice is buy them from bidproduct, or see if Lutach is going to be getting them anytme soon (having issues with the actual factory supplying him the correct motors for testing). Cheaper than a feigao, yet the same quality or slightly better even. You cant buy them in the UK- they come direct from China, but the good news is they ship anywhere in the world, shipping is cheap, and customs forms are usually marked at a nice low value to avoid import fees etc. I'd suggest the smooth can versions if you have limited gearing room, or the finned can version if that isnt an issue for your setup. Bidproduct |
well that motor seems to be doing okay oh yeah nice vid

Bummer.
Not suprized about the KD motors, they do only seem to last about half a dozen runs before the temps go a bit ka-ka. So, back to waiting for the 70mm medusas again.... |
hey neil sorry for bringing up this thread but i wanted to know what gearing would you reccomend for this motor? i just ordered the 1845 version and will be using 14 cells for now. waht gearing should i use? i have a 68 tooth spur gear. waht pinion would you reccomend? im a basher and own a 3905 (stock tires pretty much stock besides bulks and rpm stuff) and i am looking for a balance and speed and power with cool temps. i also have the MMM. thanks again if you can help.
also would you reccoemnd changing the stock connectors to the high amp 6.5 castle ones? |
I'd definately say change the connectors- 5.5mm ones are more than fine, and easier to solder/ find heatshrink tubing for too.
I have the 1845kv motor (9XL), and currently run 24/70 on 5s lipo, so I think for your 3905 truck and 14 cells, something like 24/68 comes out at 35mph, which I believe is about the best you could hope for really using nimhs and a large BL motor. Depends though, the lighter the truck, the higher you can gear slightly, so 65/24 is possible, just watch the battery temps closely more than the esc and motor. Good luck. |
thanks a lot neil. ill be ordering my pinion soon...i have to get more solder those connnectors reallt do use up a lot.

Final update on testing:
Killed it :cry: Its weird, 3 trips back the motor was fine, just needed a cooling down break after 10 minutes or so to keep things under 180*F. 2 trips back I decided to gear up seeing as the batts and MMM were fairly cool, so maybe I was too conservative on the gearing and actually under geared it. Answer was no, I was just pushing to hard and got the motor upto 180-190*F in 5 minutes, so lots of coolling down breaks that session (until I killed the tranny again). Final trip out on Saturday and I was hopeful- geared it down a fair bit and ambient temps were stupidly cold, so... Anyways, started out fine and after 5 minutes I was only at 110*F on the motor, brilliant, then a large crowd gathered round of families and kids who were in the park (who takes their kids to the park on a freezing winter's day, weirdos...), asking lots of questions like how fast/much £££/where from/ power source etc etc. I put on a little show for them; basically stupid amounts of WOT and crazy suicidal high speed passes that were rather dangerous as the crowd were stood infront and to either side of me, so I couldnt really see where I was going all that well from my parkbench/shelter location. No injuries though, just lots of 'woos' and 'wows' :mdr: (massage that ego baby), until the truck suddenly ground to a halt and refused to move again, just rocked back and forth when I appied throttle. I was hoping it was a loose pinion as I now have an all metal tranny gear setup, but nay, I saw the small stream of white smoke coming from the front of the motor when I picked the truck up, and knew it was toast; temped at 242*F which is much less than the 358*F the hobbyshitty motor died at. Upon opening up the motor I noticed the magnet was incredibley weak even though it hadnt been cooked that baddly- free spinning with zero resistance, and the windings smelt like an old ashtray again, so no saving this motor saddly. Still, I have another cool fridge magnet, and a really cool pencil holder... Anyone know if Mike will be selling the 80mm Medusas? I emailed him about it on saturday so hopefully will hear something next week (only the 50/60/70mm motors in the store at present). |
Man, i wish i had a cool magnet...... Sorry to hear about the motor.
|
Neil man time to give up on your great Chinese hope. You are 3/4 of the way owning a Neu 1515 2d with that waste of experiment. Not too fast (sometimes) not to slow (ever) for 5s lipo or your 6s a123 perfect motor !!
|
Hobbycity 9Xl = $30
BidProduct 9XL = $46 Total = $76 Not quite the ~$250 needed for a neu 1515, heck, actually about the same cost as a feigao, and that would've burnt on me too probably. :mdr: Now Im just waiting to hear back from the Monster with regards to the 80mm medusas- how dare he take a christmas break like the rest of us! :whistle: |

mine died too this christmas eve! i split the rotor right in half right after i bought my 4s pack. it was really fun on 4s but now im just going to wait for some money to accumulate and get the 70mm medusa! it was a good little motor but once i got a good battery it new its days were numbered.
