调节 FM / PPM（脉冲位置调制）
works well looks so small next to the old cristal receiver .easy to bind and good range. and no glitches.Excellent receiver, locked onto tx fast, cheap enough to put one in each model and forget about it, I wish I had got more of these instead of the Corona RS41011 with mini crystals, for which I have not been able to find matching TX crystals, HK do you sell them? How about selling a packet of 10 matching Tx crystals.Great value for the money, hardly glitchless, but no worse than any other receiver I have, will certainly buy again and would recomment, will try the 6channel next.
Binds very easily. Range is good. Solid link.Awesome receiver, using it with my skyfun kit. I lose orientation of the plane before i lose connection with the receiver. Best 4ch fm synthesized receiver you can buy. And the Price! have bound it with a JR 9XII with synthesized 36MHz module, Futaba 9C super with 36mhz synthesized module, and also a random tx that came in a rtf kit on 36hz. Thanks HK!Only one word to describe this unit "FANTASTIC". Replaced Futaba R136F & works faultlessley with the 4YF-FM. So good I bought a second one.Great little receiver for the price, easy to use and tunes into your channel quickly. I gave it 4 stars because I bought this to go with a plane that needed V-tail mixing, and I don't have a computer radio, and this receiver does NOT work properly with a plug-in V-tail mixer. The servos jitter, don't move in the right directions, don't mix properly, go full throws with only the slightest stick movement and generally go nuts. So if you want V-tail with this receiver, you'll need a computer radio.a great little Rx. Very easy to set up. Works very well and seems to have very good range. As good as the 8 channels I have been using [a waste in small electrics!]Excellent with my JR Tx. Will be buying three moreGreat Rx for the price. I had a little trouble getting it to bind but I persevered and success with both Hitec and my Multiplex mc4000 Tx's. Would highly recommend and have bought more.
