Hi Guys I'm planning to upgrade the antenna on the wifi extender and the RC controller and need few advise. What i'm planning is For the wifi extender: 1. Install 2.4 Ghz 8dbi Omni directional antenna 2. Install 2.4GHz LHCP Helix antenna For the RC controller: 1. Install 5.8 GHZ Helix antenna The information i'm looking for is: can I use either LHCP or RHCP helix antenna for the RC controller? I know i need LHCP for wifi extender but I am not sure about the RC controller. Can someone help me on this? Another question: What do you use to make a hole in the plastic body?
