I'm just starting out with a DIY build - I'm hoping to get as much fun from designing & building as from flying. I haven't decided on the 'copter size & parts yet (no doubt I'll ask questions about that in this forum soon), but I decided to start with the bits that are more generic. So far I have purchased a LiPo charger, a 6 channel 2.4GHz R/C Tx and Rx, and some 5.8GHz FPV bits (a TS353 400mW transmitter, receiver, camera, pan& tilt camera mount and LCD screen) because I definitely want FPV. My DIY so far has been to make a bracket to mount the screen and FPV receiver to the Tx unit and fit rechargeable LiFe batteries to the R/C Tx that will power it and the FPV receiver & screen for plenty of time between charges (I used LiFe because the voltage is more compatible and at £10 for 5000mA at 12V its cheaper than LiPo where weight is unimportant). When testing the setup, I found that the R/C signal affects and is affected by the FPV signal - it is usable but with reduced range for both R/C and FPV compared to when they are used separately. I can separate the FPV receiver aerial from the R/C transmitter which improves the FPV range (though not so convenient), but obviously the FPV Tx aerial has to be close to the R/C receiver. Is this interference usual? Is there any way to eliminate the cross interference? My R/C kit is pretty cheap (Fly Sky CT6), so maybe I need a better Tx/Rx setup? I thought of maybe mounting the FPV transmit aerial above the R/C aerial with some foil between to screen some of the interference.
