Swordwish 200 ?

[Brushless01]

Hi guys im having trouble with my Delta force 29 im running a Feigao 8xl and a swordfish 200 now the problem is when i let off the throttle it carries on for about a second and its really annoying is there a cure for this ?

Thanks

It should be for less than a second. But it can seem like an eternity if you are close to something. There is an update that is said to address this.

ESC saver feature?

It could well be that this is a safety feature designed to protect the ESC when a sudden "zero throttle" setting occurs. I have done some preliminary calculations and measurements that indicate a large current/watt surge can result from the transfer of the boat kinetic energy thru the prop when going from full throttle to zero throttle too quickly.

The calculation follows: (assumes 100% energy transfer efficiency to ESC)

WATTS=328*WEIGHT/(DELTA TIME)*(HIGH SPEED/60)**2*ln((HIGH SPEED)/(LOW SPEED))

boat WEIGHT in pounds
DELTA TIME in seconds between high speed and low speed (from GPS)
HIGH SPEED and LOW SPEED in mph
ln is natural logarithm
result is in watts

Example:
5 lb boat
60 mph high speed
30 mph low speed
.25 seconds delta time between high speed and low speed
type in GOOGLE search box
328*5/(.25)*(60/60)**2*ln((60)/(30))
result in watts is:
((328 * 5) / .25) * ((60 / 60) ** 2) * ln(60 / 30) = 4,547.
initially at 60 mph, dropping quadratically to 1136 at 30 mph.

I will bet that this stirs up a hornet's nest!

How was it programmed ?
The program card info can be downloaded for reference, sounds like you have some soft settings in there, I think a program card is only about $6.00 if you dont have one.

Thanks guys i will try the update ! Also i already have programmed the esc.

I programmed mine with the card and set for soft shutoff. I thought that was only for when the LVC kicks in? Mine has the same problem....runs on for a bit after letting off the throttle. I'll try using the hard cutoff. I don't have the USB connector for the esc so downloading an update isn't going to help me.

Anyone tried the update yet?

[jamie]

My program card is set at
1 ON FOR 12V LVC
2 OFF
3 OFF
4 ON

5 ON FOR CLOSE BRAKE

6&7 ON FOR 0/15 TIMING as2650kv leopard an agro motor combo for a UL1 LOL

8 OFF FOR SOFT SHUTOFF WHEN REACHES LOW VOLTAGE

9 ON
10 OFF FOR STANDARD START BUT I HAVE USED ON/ON FOR SOFT START

11/12 ON FOR 8 KHZ

Sorry im not a computer wiz so cant help you with updates but this program works well on mine and seems to be reliable ive had to shut it down pretty fast a couple of times when ive run out of room

[sailr]

Interesting. Same settings I'm using and it has the run-on problem when going to low throttle.

I'm running this V2 Swordfish 200 software (3-7-2011) and it still tends to run-on for about 1/2 second...not sure if it's fixed...

[jamie]

Hmm not sure but ive got the same brand esc on 2 hydros with the stock UL1 tactic x240 and spectrum Dx3e setups and they both work great .... Am too dumb and new to this stuff to help out much more

@sailr
ask from Michelle at HIFEI to send you the new firmware for 200A esc.i upgraded mine and no problem now....it stops normally..

This should contain the latest firmware

FWIW, the last 4 digits of this firmware are 2000; the previous version was 200L.
BTW, this latest version seems to also have a throttle delay of about 1/2 to 3/4 sec. when you chop the throttle.
