1st Brushless Conversion - 08.07.2008, 10:59 PM

Hi,
New to the forum but not new to rc. I am working on my 1st brushless conversion - went with the Jammin CRT.5
I have the RC-Monster electric motor mount on order (should be here tomorrow) but I am having a hard time trying to figure out what brushless setup to use.
Our track is pretty big but but its technical so blazing speed will not be required. I was thinking about running something with low kv like a Traxxas Velineon. Do you guys think the Velineon has enough power for the CRT.5?

Here is a quick pick after I stripped everything out of the RTR CRT.5

It'll run hot but it'll work.

Steve, Do you think it will run hot because of the 11.1v packs? Should I use 7.4v packs instead?

With 3s, I don't think you can beat a Mamba Max ESC with external BEC and a Feigao 9L motor. This will give you speeds in the mid thirties depending how you gear it, and should run well for you. If you have the money though, go try to go with a Medusa or Neu motor. Neu motors are the best motors around, but the price also reflects this... The Medusa motors are kind of in between the Feigao and Neu in terms of performance and price.

The only reason why I was going to try the Traxxas brushless setup is because the LHS I work at has a few in stock. The Mamba Max ESC is on backorder thru our distributors until late August. I want to get this truck on the track ASAP.

What Medusa motor do you guys recommend?

The medusa 50mm versions will work best for your setup.

The velineon on 7.4V will run cooler most likely, but you just won't have nearly the power that a 9L could give you on 3S.

If you want to spend an extra 40-50 bucks or so on a medusa, it is well worth it.

I went with the Velineon system. All that is left is mount up the battery box and install the Rx.
Can't wait to see what this truck can do on 3S !!

LOL - The body fits perfectly. It must have been the angle I took the picture from that makes the ESC look like a skyscraper

Thanks! It is the stock chassis that comes with the RTR. It is extended to fit full sized servos. I made a battery tray and took it for its 1st run today. The VXL is an animal on 3S!!!!
Very happy with this choice. A 1/8th scale conversion is next on my list.
