I am running a RC8BE with a Tekin RX8 system. My radio is an older Airtronics MX-3 (fm). Currently I am only getting 50' of transmitting distance before I lose total control. At first I thought it may be a receiver issue so I pulled the Airtronics and put in my Novak with no change. Back in the day when running brushed motors I used to solder on capacitors etc to reduce this. Do I need to switch to a 2.4g transmitter? Thanks!
