Re: Severe voltage drop
If they reverted back to the Mini's I think there would be serious issues with the CIM's clashing with the ground/defenses. However it is much better to be able to go over a few obstacles vs none at...

Re: Team 254 Presents: Dropshot
You don't necessarily need to use a led ring, we added 6 high power green 5mm LEDs(with resistors running of 5v) and it has really improved the illumination of the target over just 1 led ring
