I've finally finished installing rapid fire but I've noticed two weird issues that makes me think something went wrong. I've checked tonnes of times for shorts and made sure its all wired up correctly but I can't spot the problem.
1.) When the controller is turned off you can still use sync button to change mode and LED stays on
2.) LED used for RF is very dim.
My theory for problem 2 is the 1k resistor is too much and using a lower would solve it, not got any on hand so ordered some to test but for problem 1, I can't figure it out.
