I bought one of the new ones with the LiPo, and supposedly the new 60a ESC. I 've had it for a month, battery run time is terrible. Looking through ECX's open recalls, not only is there a recall for the 40a ESC's, there is also a recall on the battery chargers sent to Canada, as they don't meet CSA standards.
The firsr few runs on the truck, it appeared to be working normal, when the battery got low, it would go into slow mode. Now all it does is, after running it for a while, it will just shut down completely.
I contacted the shop here in Canada, and their solutions was for me to spend more money with them on a new battery and charger, which of course they sent me links to on their website.
I also contacted ECX tech support, which was not very helpful either. The tech also suggested my run time of less than 5 mins was considered normal, and they expected me to have the tools required to check the voltage after the charger went green.
To be honest I'm very disappointed in this truck, which is advertised as being RTR, yet I, along with many others are having similar issues, and get little to no support.
I am thankful that I paid for mine via Paypal, the store I bought it from refused to return it, so I've started a claim. We'll see how that goes...
