Electrics Help!

[wats]

Hi all. Have a couple of issues;

1. Getting a sparking and some smoke from what looks like 2 resistors when I wire up the battery?! No idea what I am doing wrong. Didn’t do this at the weekend??

2. Have a new receiver for an old Spektrum DX3s I had. Reset all settings. Plugged it, when I switch the power on all I get is loads of throttle?! What am I doing wrong again?!

Thanks in advance.

Andy
