Turnigy xk range of motors. Anyone tried them?

[jamespl]

Seen these motors in various sizes and kv. They seem to look very similar to the leopard ranges. I tried a search but couldn't find anything on them. So has anyone tried them or got any views? For the money I think I will give one a go.

I have a 4082 which will prove its worth in a week or three.

[jamespl]

Let us know how it performs

One thing ive noticed looking at the specs of the Turnigy motors is they say much lower voltages than the leopards do for their motors for a simular spec motor.

[martin]

Along with lower watts.

I have the XK3675-B-1400KV that I have been running in my 36" H&M drifter cat on 6 cell and it has been running great, for the money I can't complain

I noticed that. Maybe they don't want to step on leopards toes. Could they even be the same motors like the turnigy esc's are seakings?

Ive got the 4074 2000KV one, will be giving it a try soon enough with a persuit with 5S packs :)

[norbique]

some of their motors are 2 pole where the leopards are 4.
I have a smaller xk which runs good. For the money it's OK.
Maybe they use weaker quality bearings thus the lower max. volt rating?!

Those motors are Leopard made for Turnigy

[martin]

Yes i agree their made by Leopard but why the diff specs re voltage & watts for the same / simular Leopard motor, Are they a cheaper version than the Leopard motor.

[jamespl]

Maybe cheaper components are used. I guess the only way to tell is to run one as you would run a leopard and see if it holds up. I'm deffo gonna try the 3674 2000kv

[Browning]

I have a Turnigy 3674 1900kv in a Miss Geico and it runs great. I have about 12 or so runs on the motor now and no probs at all. On 4s the boat is GPS'ing at just over 40mph with an Octura 640 prop on it.

[martin]

Your on the money at 40mph + as it calculates out at 42.8mph with your given set up, So motor seems pretty good for the cost.

The GPS read 41.8 mph on the fastest run. I am quite happy with this motor for the price and am also happy with the setup the way it is. That hull is fun and still very drivable at that speed.

Just got my motor yesterday. It looks nice and looking at the pics of the leopard 4074 they look identical apart from where the wires exit the can.

[JackBlack26]

I just ran the 1600(box says 1500) 4082 in the Spartan I built with a 200A "Birdie" ESC today and the boat ran flawless swinging a 48mm carbon prop powered by 2, 5000mah 20c zippy $16 packs, for 4s. The warmest thing were the batteries which were barely noticeably warm. ESC and motor were as if they were never ran. I wanted to run 6s but didn't get a chance too due to my recieved getting wet. I have a leak somewhere :(

A+ stuff in my book!

[jamespl]

I was looking at those birdie esc's but thought they looked a bit too cheap. I take it you would reccomend them then?

[JackBlack26]

Definitely, but it did need a little work. More like preventive measures.

I took the heat shrink off and found the cooling plate was touching the motor leads. Also noticed the thermal transfer tape was only touching a few of the FET's. I sanded them down since they had some kind of epoxy over them and installed the cooling block using silicone based, heat transfer paste that I bought at Radio Shack. After that I bench tested it, it worked, and I applied "plastic dip" over it. It bound to my transmitter and took programming on first try. So far, so good.

I'm going to order some more since the t-180 in my Geico didn't want to work after taking 3 months off. Worked fine last time I used it. Today, I tried everything and could not get it to go full throtle. I'm done spending more than $50 for an ESC.

[rnst2]

i know keda is on sale.

[JackBlack26]

Saw that. They seem to be built the same. At that price I would go with the Keda but don't know how much difference it would be between the 4074 and XK 4082.

I might still pick up a 1300 and a 2030 though.
