Hi John,

My crawler, with a Cobalt Puller 7T installed, had an unfortunate encounter with a saltwater tidepool a few weeks ago. Fortunately, my ESC and RX were OK, but I fried a servo. I rinsed the motor off with fresh water, but apparently that wasn't good enough. One of the bearings is now making a loud howling/whining noise up to about 1/2 throttle. (It quiets down from 1/2-throttle to full speed.) Can you please let me know how to get a pair of new bearings for the Cobalt 7T? Local hobby stores don't stock the 4x9x4F bearings in that motor.

Also, what is the procedure for replacing the brushes?

Thanks.

And I predict when you get this motor you turn into a wheelspeed guy... Especially if you are thinking about a 3cell lipo.

Unfortunately, it is a known and documented side effect of buying and running a HH cobalt puller. Sad really to think of all the innocent unaware crawlers to be left with broken parts and shredded tires.

Thinking about getting the 7t with a FXR pro for the losi comp crawler when its out, would the wheelspeed of the 7t be comparable to the goat, and will it have as much lowend as the goat aswell?

John,

do you have any 7Ts in stock? Your website says that you expected some in on 02/06, but I wanted to check before I placed my order.

Also, should I expect any problems from my Sidewinder if I run this motor with a 3S lipo?

Thanks,

Jeremy

I was thinking about getting one of your 540's but...if you'll have either a 7t or 10t of these bad boys in stock sometime soon I might have to go that route instead. I see you've got some 7's coming soon, will you have 10's around the same time frame as well? And a few pages back (possibly even the first page) you said no replacement brushes were available at that time. Have you found a source for such a thing yet? If not, how long are these included brushes lasting prior to needing replacement?

Just got a few in, and they are on the site.

10t armatures are being quoted right now, but I can't get the full motor remade at this time. The 7t is still available.


Replacement parts are available now. http://holmeshobbies.com/product.php...&cat=23&page=1

Will the Tekin FX-R be a compatible speed control for this beast? Or should I stick with a mamba max or sidewinder? I'll be using a 2 cell lipo rated at about 33 amps continuous which is right on part with what your website recommends.

John, I ordered one earlier, but upon checkout, forgot to mark that I'd pay through Paypal. Could you please send me a payment request? The order number is: 3015

Thanks,

Jeremy

I received my 7t yesterday. I couldn't wait to install it in mine because I don't have all my parts yet. I took it over to ajc40's and stuffed it in one of his 2.2 scale trucks. The truck I put it in is very heavy and the 7t worked awsome. Lot's of wheel speed and gobs of torque.
