Questions?? Align Motor on a Vendetta?

Hey everyone,
My Vendetta is my first venture into electric RC cars (been big into nitro for almost 10 years) but i have been flying electric RC helis for almost a year now and i now happen to have an Align 430X motor that i a 3550kv brushless motor that i never ended up using on me Beam e4 (went with a scorpion 2221-8v2). I have a heatsink for it that i would cu a breather hole in the body for to keep the motor cool. I have ordered a Mamba micro Pro with an CM-2068 motor (6800kv) So its not like im screwed into buying more if the Align motor does not fit. My 2 main concerns are that the align motor is a "outrunner in a can" so it has vent holed in the bottom for its internal fan, could these be an issue with dirt and the like? I believe that the Mamba CM-2068 is completely enclosed minus the mounting holes. Here is a link to the align motor http://www.rcplanet.com/ProductDetai...50168A&click=3 and the heatsink here http://cgi.ebay.com/NEW-ALIGN-T-REX-...QQcmdZViewItem

Thanks in advance for you help.

welcome to electric RC then.


I think that the motor you have there might be too sensitive for RC.
I mean, yuo could try it, but arent flying motors with open cooling like that prone to hangups due to theor design?
It may work, but I would just watch the cooling, and also that you dont suck up a rock into the housing. I'd hate to see you waste a armature or something cause of a small rock.
maybe try it but, on road for a little while to see how it goes. without the air moving across it like a plane or heli, it may heat up quickly.

I wish you luck though, and welcome again.

The motor is an open design, but can easily be sealed with thin foam over the holes. It's a very powerful motor torque wise compared to the smaller 2 pole motors.

Go to the drug store and get some gauze that is self adhesive. A wrap around the can and over the hole will keep out dirt but allow the motor to breathe. It will stick to itself and when dirty remove and throw away. Cheap protection.

OK, so as a general opinion would you guys recommend going with the Mamba with a smaller pinion or the Align with some precautions to prevent dirt from getting in there?

The Vendetta is a little heavy for the mamba motor to be happy with - it will run hot no matter how you gear it. I tried using a 5400 in a miniquake and it ran hot period, 11 - 19t pinions, didn't matter. I put the 5400 in a much lighter M18mt and it runs great, has yet to get anywhere near as hot as in the MQ. Vendetta may be a little lighter than the MQ, but not enough to make mamba run cool.

I'm not only one thats esperienced mambas running hot in either MQ or a Vendetta either. Plus with mamba - you have to find 2mm pinions, which didn't use to be easy. Before BPP went big scale, he used to offer an align option for 18ths. I'd go with the Align.

youch! $11 for a heatsink! But the thier credit they would do the job quite nicly as i have an air intake on my body infront of the motor at about the level the fins would be, and i was to put an outlet right behind them, they would work quite well.

Here's a diff design thats cheaper (may not be as effective with "natural" cooling vs a fan) -

hmm, i think i might just go with the heatsink from the toyz as i have bought from them before, but reguardless ill give the Align motor a try on some pavement and see how i like it.

the use of an outrunner in the vendetta goes back to when the vendetta first came out over 2 years ago... the outrunner will work if it has enough kv... and it will have to geared accordingly..

Well, the lower KV gives you more torque as a general rule so i was under the assumption the a lower KV motor would work more often than a higher KV motor

true.. but if the kv is too low.. there will be no way to get any real speed out of it.. you want something that you can be pleased with at 16/45 this is like the mid of the road... if you need to go slightly higher then thats fine,, and also if you need to go slightly lower... but if you have to gear the thing to the absolute lowest it could go just to get speeds from it..... then it isnt worth it..

if you have to gear it at 24/41 then is it worth buying since you will limit yourself to one gearing... something that is 3600kv or more would be great...
