Mike Downs Posted July 26, 2010 Share Posted July 26, 2010 I am going to use an AR500 Spectrum reciever in a twinstar electric model...would the range be good enough...as I have heared that it is for indoor only.... Any advice gratefully recieved! Quote Link to comment Share on other sites More sharing options...
sparks59 Posted July 26, 2010 Share Posted July 26, 2010 Sorry Mike, can't answer, but i'm sure Spectrum will provide some spec data on the AR500. I use cheapie HK TX/Rx made in China, and they are good for as far away as i'd want to fly a 37 inch parkflyer, (over 500metres). sparks Quote Link to comment Share on other sites More sharing options...
David Ashby - Moderator Posted July 26, 2010 Share Posted July 26, 2010 It's a full range unit Mike so go ahead. I've seen AR500's in far larger models. Quote Link to comment Share on other sites More sharing options...

I've seen AR500's in far larger models. Absolutely agree with David - the AR500 is a full-range receiver - and that's as far away as you'll ever want the model to be Pete Quote Link to comment Share on other sites More sharing options...
Mike Downs Posted July 26, 2010 Author Share Posted July 26, 2010 Thanks all! One other question...... there is a long (6"0 ) ariel and a shorter one approx 1 1/2 " is there any prefered way they have to be laid out in the fus? Cheers Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted July 26, 2010 Share Posted July 26, 2010 At right angles to each other if possible ( only the 1" tip of the extension cable is the actual aerial ) Quote Link to comment Share on other sites More sharing options...
Doug Ireland Posted July 26, 2010 Share Posted July 26, 2010 Mike, Despite what others may say about them, I've got four of these little Rx's and never had any bother.Edited By Doug Ireland on 26/07/2010 23:44:30 Quote Link to comment Share on other sites More sharing options...
Lee Smalley Posted July 27, 2010 Share Posted July 27, 2010 who goes around saying they are indoor only !!! Quote Link to comment Share on other sites More sharing options...

Despite my misgivings about the long term future of DSM2 I bought yet another AR500 yesterday - that'll be my fifth one. I do tend to fly a long way off with my BVR Tucano and the link looked rock-solid to me. The same goes for the ones in use in my Mini Edge 3D and my boy's Ripmax Spitfire which are both flying well out of what I'd deem to be typical parkflyer ranges and have beencompletely rock solid so far.

Tim Mackey Posted July 27, 2010 Share Posted July 27, 2010 I have 6 of these units now, in models ranging from simple sloper wings, to .90 sized four stroke Spitfire, and a 63 " Spacewalker. Never had an issue - they are great, IF you install them correctly.I firmly believe that almost all reports of poor performance is probably down to sloppy installation. They are as stated earlier - full range, but as an aside, I also have several so called park fly range Spekky rx, including the older 1st generation DSM AR6000, as well as the 6100s and they all perform superbly and WAY beyond what would be normally classed as park fly range.I have a 6000 DSM in my 46" Wildthing and regularly "speck this out" up at the Orme.

leccyflyer Posted July 27, 2010 Share Posted July 27, 2010 I've taken to installing these with the long aerial in a piece of heatshrink CA'd to the fuselage side, ensuring that the aerial is retained in the correct orientation, perpendicular to the short one, but without directly taping it down.The received itself is velcroed or servo taped to the fuselage internals. That comes from having torn both aerials off a Frsky RX when the fuselage sides, to which they were taped, parted company in a crash in which damage was limited to the entire fuselage.

GONZO Posted July 27, 2010 Share Posted July 27, 2010 Take a look at these test results on 'post 35' HERE Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted July 27, 2010 Share Posted July 27, 2010 Gonzo - tests done in the US need to be treated with care, since the UK spec transmitters have a lower power output of 100mw versus >200mw for the US-spec versions. Quote Link to comment Share on other sites More sharing options...
GONZO Posted July 27, 2010 Share Posted July 27, 2010 Agreed, USA - 200mW ; UK - 100mW. But, half the power will not reduce the distance by anything like 50%. It's a square law relationship, probably only reduce by 20% - 25%. Quote Link to comment Share on other sites More sharing options...
GONZO Posted July 27, 2010 Share Posted July 27, 2010 Should have added in my previous post that it was not the absolute distances that I was drawing attention to but the comparative distances obtained between the rx tested. IMHO not that great between 'near top of range' to 'park fly'. Of course in model flying use signal path diversity will play its part and those with satalite units will show an advantage.
