Phil May Posted May 12, 2016 Share Posted May 12, 2016 Morning guys. In a few weeks I'll be picking up this 48" span F4 PSS model and considering fitting some scale navigation led's. Having never fitted these before can anyone advise me on how and what I need. I want them to be bright enough to be seen clearly in daylight. Thank you guys Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted May 12, 2016 Share Posted May 12, 2016 Hi Phil. Getting lights ( LED or filament style ) bright enough to be seen in daylight is challenging, and usually requires a bit of relaxation on scale size. "Power" leds are the way to go, but despite them being cooler than filament lamps, they still generate a lot of concentrated heat, so bear that in mind too. Powering them is fairly easy as long as bear in mind the two main things. 1) Unlike filament lamps, LEDs are polarity concious so must be connected correctly. 2) Excess current is baaaaad - as with many electronic devices, its not the voltage that killes them its the current. Current limiting resistors are used in series with the diodes to limit the maximum current and this will vary with voltage. You can run them off almost any voltage above 1.5, but limiting resistors MUST be used. I normally run mine off a 2 or 3s Li-Po fitting resistors as required. Ultra bright LEDs will use a fair bit of power, so dont run them off your main flight pack, unless you intend them to be on for only very brief periods. Braincube and others supply complete solutions if you dont fancy building up your own looms etc. Several palces now also sell rc switches which can be used on a spare channel to switch the lights on and off Edited By Tim Mackey on 12/05/2016 11:11:46 Quote Link to comment Share on other sites More sharing options...
Cuban8 Posted May 12, 2016 Share Posted May 12, 2016 Google is your friend **LINK** Plenty of other suppliers on the web etc as well. To be honest, I've never seen a navigation lighting system that works well in full daylight or even on cloudy days. Quote Link to comment Share on other sites More sharing options...
Andy Meade Posted May 12, 2016 Share Posted May 12, 2016 These guys did the kit for the Hawk noselight. I will be using them again for the C17. Ordering and the website is a bit clunky, but it's wayyyy cheaper than anywhere else, and his stuff "just works". Quote Link to comment Share on other sites More sharing options...
David P Williams Posted May 12, 2016 Share Posted May 12, 2016 +1 for the lightingforaeromodellers.co.uk chap - good candidate for worst website in the world, but he's always been helpful on the phone and his stuff is cheap as chips. Used it on lots of planes and helis. Quote Link to comment Share on other sites More sharing options...
