Good Afternoon & hello,
Hello from Cheltenham, first post here, so thanks for taking the time to read this.
I really need some help with my sons FTX carnage.
About 6 months ago my 10 year old son started showing an interest in RC cars, he had some of the useless nonsense from local toy shops and was taking them over the local park to play with his mates. I have always secretly wanted an RC car (44 years young) and so started researching decent starter cars for him. Thats when I decided upon a brushed FTX carnage for him.
Initial thoughts were promising, although it was slower than we hoped. However battery life was a serious issue, we were only getting 5-7 minutes from the 1800mah battery supplied with the car.
After a front shock disaster (replaced for £10.00 on eBay) i then started looking for a larger capacity battery. Shortly afterwards i purchased a 6800mah cheaply on eBay, now i have no idea whether the battery was rubbish (probably) or the carnage charger wouldn't charge the larger capacity battery, but we still got roughly the same runtime from the larger battery (all be it, the car was faster for some of those 5-7 minutes).
So i then made my second mistake and purchased a cheap imax6 charger from eBay, this seemed to make the situation worse, and really didn't charge the batteries any better than the supplied charger that came with the car. Of course it was then retrospectively that i researched the charger and found out how many fakes there are on eBay, this was definitely one of those fakes....typical.
Money refunded I got to keep the charger to use as a paperweight.
I then purchased a second hand SkyRC T6755 and tried to charge the two NiMH batteries that we now had. Now I am not sure if the fake charger had destroyed the batteries but the results were very similar, poor running time and not much power.
So far my introduction into the world of RC cars was starting to become a pain in the arse!
Anyhow, after some research I purchased a 7.4v 5200mAh 2S Lipo, the difference was amazing the car now lifts it front wheels and was (notice was) so much faster than before, the T6755 charges the battery properly and the car is everything it should of been out of the box. Big grins all round, great car, much fun, son involved and interested - things looking good.
However today, my son came back from the park saying the car had started smoking. On a brief examination i have noticed the cables coming from the ESC to a capacitor/or resistor? have burnt out and this is where the smoke was coming from (picture attached).
It fair to say my brief excursion into the RC world is fast becoming expensive and is proving to be a very steep learning curve!
Now I am assuming that I need to replace this Capacitor/resistor? with a higher rating item, but am hoping that kind members of this forum can point me in the right direction!!
I should add that I changed the ESC into low voltage and thermal protection mode before using the Lipo.
PLESE HELP?????
Thanks
Tom
