Help!
Turnigy Plush ESC

Recently ordered a couple of Turnigy Plush 12amp ESCs from Hobby King, and am hoping, after the fact, that they have a reverse!!

Looking to use one in my Dumas 41" UTB, the small version, as well as a Carol Moran Tug, when it arrives!!

Any feedback would be greatly appreciated!!

Many thanks, in advance!

Anyone have knowledge of these guys??

Looks like a flyer's ESC, one way only. At least they're cheap...

more expensive than the turnigy, but this is exactly what i am using in my small dumas inspired 41' coast guard:

my UTB is not really the dumas one, however, and is considerably lighter. the esc i had in my real dumas 41' was a castle creations micro sidewinder, which is twice the price of the losi esc.

however.....

this one has identical specs to the castle, plus it is supposedly waterproof and watercooled, but is still almost 3 times the turnigy price:

Plush has no reverse as has been mentioned, Get the 30 amp (there's an 18 amp version as well) car ESCs for about $15 from HK, better cooling from the exposed heat sink compared to the plush and I've found them to be reliable so far.

Many thanks for the input, guys!! Much appreciated. Guess I can return the Turnigy's to Hobby King and pick up on something else I'll need!
Also, oddly enough Tim, I ordered one of the 1/36 Excelorin escs from Horizon yesterday afternoon!! Recalled your mentioning it in one of your 41 footer builds! At only 30 bucks, this'll probably be my "go to" esc for future builds! What do you think of the Excelorin 1/36 motor that couples with the esc????

crazygary...

i don't use the losi motors.... they are way too fast. like 10,000 rpm per volt. the motor i have in my 41' utb is a himaxx 2212 outrunner. I think it is the 1120kvm model. excellent low speed "loitering" abilities. for a slow speed scale hull i highly recommend the himaxx motors. motors start spinning slowly one click from nuetral, and no noticeable cogging.

they are expensive, however.

Hi, Tim!

What would be the main difference between the 2211-1120, and the 2212-840, aside from the obvious kv difference? Is one more apt to be a little slower, like maybe for a tug, or would you suggest something else for a tug?

crazygary, you are absolutely correct. the only difference between the two is the speed of the motor. one is 2/3 the rpms of the other.

for a tugboat, i think the 840 is still way too high. I have two AXI 2212/34 silver in my 25" lil' shelly foss through a 2:1 gear box, at 6 volts, and still are overpowering it. I am thinking for direct drive on a tugboat you would be best off with something as low as 300-350kvm.

and again, expensive

Hiya, Tim!!

As always, your input is most welcome!

I looked up the motor on the link you posted, and price is listed as 49.90. It looks to be in Euros??? That's roughly 62 USD. (1 Euro=1.249 USD)

Once again, many thanks for sharing your expertise!! Much appreciated!

Gary

i presume its for the Dumas Carol Moran Tug listed in his first post...

http://www.dumasproducts.com/product...69d7gd8ra58j97


the 300kvm robbe motor i listed earlier is a 36mm diameter outrunner, which might be too large for this little tug. you would be better off using one of the tiny himaxx with something like a 6:1 gearbox from an airplane

Tim-

Any thoughts about the servo hack that Dumas refers to for powering the Carol Moran??
Would prefer a motor and ESC, but if the servo trick is viable, I may give it a shot!!

The Servo Hack works the same as an ESC, the slightly tricky bit is connecting the very short motor shaft to the prop shaft. A low power application like this only needs a piece of silicone fuel tube or rubber tube that is a tight fit on both shafts

I think for this small boat would probably be OK, any brushless motor in a size suitable for this boat will need a fairly high ratio gear reduction.

Thanks or the input, Nick!

The Carol Moran kit includes a piece of vinyl tubing for that very purpose. I believe I'll give her a go, and if I'm not happy with it, I'll go with Tims' suggestion regarding a small Himax motor with a gearbox! Was kind of considering Dumas' 4.8V motor, but not knowing enough about it, would rather go with something proven.

Many thanks to all who contributed to my query!!
