Setup of Spektrum DX2S with Swordfish 200 Amp ESC - Newbie needs help !
As a total newbie to electric boating (but not radio control aeromodelling) I need to ask some seemingly basic questions to the settings required on my Spektrum DX2S radio & the Swordfish 200 Amp ESC.
My DX2S radio has the trigger throttle with the forward part of the throttle trigger arc being the "brake" section (I'm assuming only used by the Tx for cars / trucks etc).
I tried last evening to calibrate my Swordfish ESC with the DX2S & was able to stop the boat motor turning when the trigger was pushed fully forward but upon release to the spring loaded position, the motor leaps into life running at a fair tilt. The Spektrum manual appears to be written predominately for car users who would find the brake function handy, nothing written there about its use or otherwise in boating. So my questions are:
1/. is the "brake" facility on the Tx used for boating?
2/. If not, how do I turn that feature off?
3/. Is it done via adjusting the Travel & Trim settings on the Tx (ie: electronically turned off by the software) ? If so, what are the values I need to input into the Tx ?
Sadly last evening, I blew up my Swordfish 200 Amp ESC during bench testing - made a crackling sizzling sound & emitted the traditional blue smoke. Perhaps the "brake" settings somehow caused grief inside the ESC, causing $110 worth of damage (price of a replacement) - I simply dont know. The BEC function would still power the receiver but that'a all the ESC now does. I tried another ESC (an aircraft one) & the motor works fine, so I have confirmed the Swordfish is now dead for practical purposes.
Need to get this issue sorted before my replacement Swordfish ESC arrives - dont want to fry it as well
As I say, am a total newbie with electric boats & a trigger style Tx - all responses will be most appreciated - thanks.
