Feilun FT012 problems


Hi guys this ft012 is brand new & first run yesterday went well. Today however after charging the battery & taking it to the pond I only got 3 laps before it quit.
After lap 1 I unplugged battery shut off xmitter then it reset & ran ok, lap 2 same thing battery & xmitter reset went one lap before slowing down.
After 3rd reset I opened up throttle wide open with boat in water it went real fast then slow.
Then nothing at all on throttle only rudder & drifted back to shore.
Checked battery voltage it read 8.04 volts.
Any idea what's going on here camon man 2 bad boats in 2 days just ain't right❗

This happens a lot when one buys the cheaper boats. Fei Lun has never been known for top quality. My own FT012 doesn't have any of their "works" inside of it anymore.

Yep ya Live & Learn I'm done with Feilun sending them both back to the stores they can have them����
On a lighter note I have a WL913 on its way from a international website I ordered it from so hopefully it will work out. I understand parts wear out & can be replaced but when you only get a one time use out of something before it breaks it can be quite disappointing.
I'm also considering the WL915 Tunnel Hull boat to try as it seems pretty fast & has good reviews.
I built Nitro boats back in the 80s so been there done that now I just want to play not work on them all the time.

Good luck with that. WLtoys is a bit in the mid-quality Fei Lun class. Stick with 3S power unless you swap in a better motor and ESC.

Today I sent the FT012 back in the mail & co is refunding $ so went & purchased a WL915 still waiting for the 913 to get here from overseas.
I'm stuck with the Feilun FT009 company didn't want it back & gave me a $20.00 refund.
I recharged its battery today & after charging it was puffed up & measured 7.82 volts fully charged.
I was able to get the boat going again after pairing it but it only ran into the middle of pond then stopped. After it drifted to shore battery voltage was down to 5.54 volts. Now I'm beginning to think the battery is no good.
What do you think about it❓

I think a new battery is the only way to find out for sure.

Make sure you store the battery charged to a nominal 3.8 to 3.9 volts per cell, or 7.6 to 7.8 volts for a two-cell pack (2S).. Never store them with a full charge or depleted past that voltage point.

If anything, maybe you can get the '009 working reliably and make a rescue boat for your fast vessels, as I did with my FT009: https://youtu.be/S3C8WMKLEwE?t=0

AirDOGGe I think your right this battery puffed out really bad on just one side after charging it today & I noticed it discharges on its own. It was down from 7.82v to 5.54volts after the run to middle of pond. Now from just setting not hooked to anything it went from 5.54v down to 4.59v & seems to be staying at 4.59v so if on cell of the 2s is not holding its charge then it's defective & that's why the boats not working right.
I did buy the 009 to use for a rescue boat after seeing MRMAD2424 on YouTube using his rc boat as a rescue I have a kayak also that I only used one time so it should come in handy with my luck.
I found a 2s 7.4v 1500mah 2 pack by seajump on Amazon for $17.99 The batteries are round, is this an older style lithium battery?

Some are round, some soft flat packs.

This is the best price I could find for a 2s 7.4v 1500mah with that particular "EL2P" plug.

If you can swap plugs, then you can get deals like this: https://www.ebay.com/itm/ZOP-Power-2...95ad1fe1e3c39f

I have a couple of these under the "Venom" and "Turnigy" brand names, though they are the same identical charger. I like them because they can charge two 2S packs at the same time and independently, or charge a single 3S or 4S pack up to 3000mAh.

Here it is again under yet another brand and $5 cheaper, same thing except for color of the plastic case and decals: https://www.ebay.com/itm/Redcat-Raci...AAAOSwImRYcHEn

Ok I'm watching a couple of those chargers you sent links to on ebay. I did order that new battery today for the 009. I'm thinking of doing away with that mess of red wires for the safety feature & just soldering the black & red together. Any issues with this❓Thanks for the info too.
