Viper 15 ESC
« on: October 22, 2008, 07:12:52 am »

Hi all ,
      New to boating a recent convert from aero .I purchased a Mtronics Viper marine 15 ESC  and set it up on the bench with the motor and spectrum Rx it all went as it should the first time motor control worked forward and reverse,switched it off and tried again 5 mins later smoke from the ESC(where the Rx joins the unit)no short circuits The unit now powers the motor but the switch or throttle control on my Tx have no effect on the motor it just runs?
I have read on other threads that similar problems have occurred with this unit .
In contact with the seller and Mtroncs not too hopefull as I did change the battery connection for a deans.
my question is what could of caused it ?
what speed control unit would you recommend for a Deans ASRL?
Thanks in advance Chris

as its a fast boat go for a Electronize as they can be repaired, I prefer them and have used them in that type and size of hull.

At a guess, the power neg wire was not as connected as you thought.  As a result, all the motor power was trying to go down the thin wire to the RX.  This protested by vaporising itself.

A friend also had his working Mtronics go up in smoke, sent it back, a replacement arrived 3 days later....
  and another one the day after that.  :-))

I had a 25a one that failed ,no reverse ,only full power and off on forwards and blue smoke from reciever side .Had a word with the guys at Mtronics and sent it back ,unfortunatly it could not be repaired as the reverse fet had blown but they did replace it for 20 , dont forget a new one would cost nearly 40. .
And i had the new one back within the week , now thats fast.
