Default Tornado EPX Discussion and Picture Thread

Well, as long as I have been browsing the RedCat Racing thread, I rarely see any posts on the Tornado EPX. It seems these cars are fading out. If I type "Tornado EPX" in Google search, most of the cars that come up are the Brushless, Pro, versions. Very seldom does a standard Tornado come up.

So, I decided to make this thread for all who have a Tornado EPX. I thought it would pretty cool to have a thread where you can discuss anything about the Tornado EPX. Maybe your stuck on how to fix something, can't find a certain part, or maybe you just want to show your Tornado off.

Anyway, to start of, here's mine:

sorry to post, but here is my tornado EPX PRO.
since this pic was taken, i modded the rear to have 4 shocks instead of just 2. makes the rear shock tower hold up better for extreme jumping
the PRO is the same chassis as the EPX, but has a novatch brushless system.(And the now they come with a 2.4ghz radio)

Igot my tornado epx pro at a local hobby shop a couple of weeks agoI used the stock batt and 2 or 3 passes it wil completely shut down but the fan is still running,inconclusion i touched the engine, it was cold so i googled it. Later i found out that the reason it shuts down is because the stock batt doesn't put out enough power. I now run a sky lipo 30c 2s 5000mah. It puts out a great amount of power for the tornado epx pro. And a really good charger for lipo batts is the thunder ac680.
Other Recommendations are that you should get are billet rear shock tower, and billet front shock tower because the the stock ones bend easy,last but not least 4 racing shocks do that and you'll be good to go.

Hi Guys,

I got the Tornado EPX back in August 2014. No issues what so ever, but recently I noticed it doesn't start rolling smoothly from a dead stop. It does a jerking motion for about 6 inches then once its rolling there is no issue. It does the same thing in reverse. I took everything apart to look for binding or bad bearings in the differentials, and motor housing but everything looked perfect. I put it all back together and the same problem occurred. I'm using a 2s 5000mah battery with cut off set to 3.4 volts. Start mode is set to level 3. Any ideas why it isn't starting smoothly? I appreciate your feedback.

I just started having the same issue with my tornado described above. It started when I switched to dirt hawg tires so I'm not sure if it's over heating the motor and causing the issue. The motor temp registered 140*f and the esc was a little under 110*f.

Conquest - I did more research on this and found that it is not uncommon for brushless motors to behave this way over time. The term used to describe it is "cogging". I took my motor apart, cleaned it with electrical cleaner spray and found it to operate better, but it still cogs to some degree. The tires could have some impact, because if they are bigger they will cause more load on the motor. There is a lot of info on the internet on cogging. From what I read, there isn't anything you can do to stop it entirely without replacing the ESC and maybe the motor with a sensor less setup. (Not sure what a sensor less set up is exactly). Good luck my friend.

Thanks so much for the info. After looking up this condition it seems just like what I'm dealing with.

You're welcome. One other thing to check is to make sure nothing is binding and all wheels, axels, bearings, etc... rotate smoothly. I recently found a suspension pin had come loose and was rubbing against my front tire. After I reinserted it, the cogging was practically no existent.
