Corona Synthesized Receiver 4Ch 72Mhz
Gooi uw kristallen, afscheid te nemen van glitches! De nieuwe Corona gesynthetiseerd ontvanger is hier!
Dit apparaat werkt met bestaande gesynthetiseerd zenders of kristal zenders. In feite zal de nauwkeurigheid van deze ontvanger de prestaties van alle 72MHz kristal zenders verbeteren.
De RP4S1 is de kleinste en lichtste gesynthetiseerd systeem vandaag beschikbaar zijn. Dit kleine formaat heeft geen invloed op de receptie de kwaliteit of de prestaties, omdat dit toestel heeft het grootste bereik beschikbaar vanaf elke Corona ontvanger plus een sensitiviteit groter dan 2uV. Tests hebben aangetoond dat het bereik meer dan 1 mijl zijn!
De nieuwe technologie in de gesynthetiseerde reeks Coron ontvangers zetten is echt uitstekend en zal zeker je wel twee keer na te denken over het upgraden naar een duurdere 2.4GHz.

Have been using these receivers for over 3 years in various types of airplanes and all have operated as advertised. I have found that they will even discriminate other transmitters on the same frequency (channel). Have never had the centering problems that some others are having. Centering problems are more commonly servo problems.I have these in all my planes that only require 4ch or less. I have never had centering problems (Thats the servos job anyways) and GREAT range. Very light and easy to fit into tight spaces since they are small as well.The centering is somewhat bad, but since I'm using it on a micro model, I don't notice. The pins are pretty close together, but manageable. I'd pay ten dollars for this. Not 16.Great little receivers binding the thing was a breeze. i have not had any centering problems with mine super precise and the range is great i have one of these little guys in my sailplane and my altimeter read at 3500ft when i landed. however i have had some problems, one receiver i received the pins that the servo plugs go into were lose for some reason? i was able to make it work again but i do not plan on unplugging anything anytime soon. so there are some quality issues but other then that they are great.I have bought ten of these. three have failed. when they work they are good but expect failures. jittery and unstable when they go.
Wow! I wasn't actually expecting it to work with my cheapie walkera tx (the one that came with the dragonfly 4) but it worked flawlessly! Thanks HK!Hi guys!! At the moment, this receiver works. I did test about 600 meters without problems.good reciever, synched right up with my 72mhz futabaI have two of these units installed on home-built foam board aircraft. they binded well to my Futaba EX6A radio. I cannot report a single problem with either unit. For the price, compared to the Futaba units, these are almost as precise at a third of the cost. Use in <36" wingspan foamies is a no-brainer. They are extremely small and fit just about anywhere. I just wish they came with in a light-weight case for ease of mounting. Using hook and loop tape works well, and makes up for the lack of flat surface for mounting. But their light weight make them perfect for mini, mico, or any small frame with a total flying weight less than 1lb.
I will be purchasing more as I increase my collection of aircraft. However, my next step is to get a 6ch dual-conversion unit for a larger aircraft with more options.Can anyone tell me the exact length of the antenna that comes with this receiver?. I have ruined the antennas on both of my receivers and had cut an antenna (standard calculation) for my frequency but had very little antenna down range with my 6XA. Even with transmitter antenna fully extended, it was getting glitches just outside the field perimeter and have never had this short of range on these receivers..
My usual range was nearly out of site.. I think that the standard length one detuned the receiver...so I nee the correct/facory length...thanks
