Ned Help Pleasssssseeeeeee Swordfish 240Hv,s going itno LVC

Like what Boyd said above. When his started doing what yours is doing it was because the controllers went bad. Time to send them in and get them checked out and fixed.

I'm glad you found out the problem and were able to get it fixed. Too bad it couldn't be fixed that weekend - I REALLY wanted to see a 100 mph pass!

Hi Jay,
I'll be back in March with a half dozen controllers in hand and get that 100 MPH+ run

[thomaslambo]

I isolated each motor and esc and ran them seperatly, (one at a time) and both did the same thing. Only ran for a short period of time then slowed right down.
I tried both batteries on each esc with the same effect, so its got me beat.
I will go through all the soldered joints again and make sure there is no dried joint.
I disconnected the y harness and plugged the esc straight into the receiver, one at a time and it still didnt fix the problem.
I will recheck all the connections on more time and see if any thing is loose.

I tend to agree with Mark but if you have the extra gear I would try one last test.
Take one of your controllers and connect it on the bench to a different motor, rx, and battery, using a differnet model no or transmitter and test it again (or give one ESC to a friend and let them test it in another boat).....if it fails under those circumstances then send both controllers back to the Michelle.

Good luck

Do you possess one of the handy balance plug voltage checkers ?
Take note the pack voltage when the setup slows to a stop.
Those cells, though charged to 4.2, may have poor loaded voltage sustainability.
Try a different pack !
Doh .. is your Tx flat .. there's a failsafe there too !

I tried a different Tx pack with the same effect and I dont have a voltage checker, only the one thats on the charger.

This morning I bench tested the system using different esc and all was ok motors ran perfectly. could throttle up and down with great response.
I will ship the esc's back today and get them fixed. Its just strange how both played up together. Will keep you all posted of the outcome.
Thanks to everyone who helped out, it is much appreciated.

And here I thought that the Castle controllers were the only ones with problems and the Swordfish were trouble-free...

j/k. I am very glad the OP identified the issue - I forgot about the Y connector effecting both ESCs, good catch Boyd! It is looking like I won't be there to see the 100+ passes in March, darn!

Sorry you won't be attending the March event, you'll be missed.

OK, just received a email from Michelle from Hifei and they have fixed both ESC. Apparently both esc had a resistor which became oxidized and that was causing the problems.
I will let you guys know how they preform when I get them back.
A big thanks to hifei for the quick response, but the real test will be when I get them back into my boat.
I have some plastic dip here at home, do you think when I get my esc back I should give them a dip and waterproof them?

[thomaslambo]

Peter,

Was wondering where you stored your boat in between runs (and what temperature ranges it was exposed to)?

[Flying Scotsman]

Use Corrosion X

make sure all your gear is thoroughly cleaned and dry before putting it away.
"oxidized" is a polite way to say it got wet
as mad douggie suggests, corrosion X is a great preventative to corrosion.

I stored the boat on the boat shelf in the garage, it was winter here but we dont get really cold winters like you guys get in the USA. Our winters here we still were shorts an T-shirts. I do make sure after I run the boat, that its dry. Boat doesnt leak and I always tap the hatch down.
I will go and buy corrosion x and spray the esc when I get them back. I suppose water will get into anything if given half the chance.

Dont tape the hatch down for storage.
Whatever miniscule droplet of water that is inside cannot escape and may reek havoc.
Nothing is ever 100% dry
Corrosion X on all electronics, and a roll of soft tissue/toilet papery stuff will do the biz to absorb any remaining moisture.
Humidity is a killer also..

cheers and good luck

[wetsleeves]

You misunderstood me, I always tape the hatch down when I run the boat. After I have ran the boat an cleaned it, I store the boat with the hatch off for about 4 days to a week to let any water that may be in the hull evaporate. Then I place the hatch on and leave it.
I will try the tissue paper thing. Do you roll tissue paper around your electronics, or just place it in the hull?

[drwayne]

just pack it in.. loose paper has more surface area for absorption.
