Do we carry the right Mtroniks Speed Controllers?

Please take a look at the Mtroniks boat web page and vote on which ESC's we should keep in stock.

Mike,
these are a good product and I used the 25 and 20 ones, the one thing I would like to see your site selling is a step type (non linear) BEC (separate voltage regulator). As Mtroniks support alluded to the on board BECs might not be up to the job of supplying power with all the servos and whatnot we have hanging off the RX and using the BE circuit on the ESC.....in fact I can tell you IME I have had a multitude of problems utilising the ESC's BEC. You by pass the onboard BEC with a separate unit (removing the red wire from the ESC), and the ESC works just fine.

As a rule of thumb now I don't use any ESC's BEC when it comes to running submarines.

A cheap and simple dodge you can try with a linear BEC, is to hang a moderate value (200-300uf)electrolytic capacitor off the 5 volt line. This acts as a reservoir enabling the system to better cope with larger demands of current without flaking out the voltage regulator used for the BEC.

Servos can use surprising amounts of current at peak, but they only draw it for brief periods. Submarines will give servos a harder time as the watertight glands introduce a lot of friction that you wouldn't see in other models.

Make sure you observe the polarity of the capacitor.

But you forgot to do the poll!

Andy this is a good tip but I think Mike is looking for feedback on what ESCs he should carry - I guess I derailed this a bit, but my point remains Mike, for the guys who want to buy off the shelf products who may not be that electrically talented (I include myself in this category), a separate BEC might be a good complimentary product to ESCs you carry. I think Kevin M might be able to give some good guidance here.

Actually, I forgot that I'd set the poll to read so the result wasn't published. (No point in doing a survey and letting 'The Enemy' know the results)

I see we've had a few people take the poll. Thanks guys.

Other points duly noted. Please don't stop adding your ten cents worth.

yes I have voted.
