If the product is covered under warranty, the shipping cost from customer to us is paid by you, in return we will pay for the shipping cost for returning the repaired product to you.
Pls note Oscar
Thank you :)

That would be so grateful Oscar
Thank you in advance :)

Thank you for your concern, we are fixing it now, and we are going to release new exciting items for Hifei esc users.
Thank you for supporting our products :)

Hopefully you change up the sf300 some. Can I make some suggestions?

Increase the amp capacity a little. Say 350a nominal and 450 burst

Get rid of the double wires. Pain in the neck to wire up. Use a single 6ga for each side instead. Much better.

Get rid of the jumper hose for cooling. Very unreliable. Hook the cooling tubes together with a hard tubing at the end.

Power switch not needed.

Please epoxy coat it better. Many spots are missed that I notice upon inspection.

Please please update the firmware for smoother throttle operation. This would be a very big plus.

Thx Gill. Trying to help the swordfish escs evolve a little more. Even tho I'd had a few issues they are my go-to esc on most of my builds. I've never smoked one, just had one stop after a hard flip and a couple minor instances in customers boats likely due to the cooling line being kinked. I used to not check them but I do every time now. It's a little embarrassing when you have a setup tested and proven for you then repeat it in a boat for someone and the esc stops working. I'm glad hifei is a very receptive company and willing to acknowledge and correct these minor oversights. As long as the hose isn't pinched these are great escs. I own a few of them along with some 220's. I'm curious to see what they have in store for us. I can't wait!

LOVE where this is going. I know this is asking alot but a smaller footprint would be nice too. I totally agree with the quality control. Ive had one out of three Hifei hv ESCs fail the first or second time out. Sad part is most of us write it off as par for the course and say nothing spending another $250 to get moving again. If the earlier requests can be met I see the Swordfish ESCs dominating the hv market.

Michlee, seeing there are a few picture examples of the cooling issue, what's going to be done about it? Why do u need them back if pictures have been provided?

Hey Oscar, about cooling issue, we already showed pic in forum to our production manager, let him know what his workers have been done, and what's going to be done about this sort of issue.
Customers are always first, we wanna make sure their issues get fixed. So we will change them new If we get esc like this.
Wish you a nice evening :)

Summer,

Thanks for the reply and I will ship out ASAP.

Which Carrier should I use to send back? US Postal, DHL, Fed Ex ?

I have few controllers that need service
Do I need an RMS Number to return them all for repair?

Thank you,
Michael

So Michlee, I have a pair of 300 Lites that are intended to power a pair of Lehrer's in my HPR these are new in box and needless to say I do not want any catastrophes with a $$ build like this. Should I just check them out myself or wait to see your changes and go from there? They are not likely to see use till next winter so no rush.
