RE: ONE RECEIVER OR TWO??
 

The main point of this is there is a lot of misinformation out there about why you MUST run 2 receivers. If you CHOOSE to run 2 receivers that's fine.. that's up to you. I choose to run 1, and accept whatever risks there may be with a single point of failure. I also run dual batteries through dual switches into this one receiver. The reality of electronics is once something passes a burn-in test, it's unlikely it will fail through non-abuse. I see a lot of VERY poor installations these days that could easily contribute to receiver failure. People have gotten away from wrapping receivers in foam and softly mounting them for some reason. I see receivers velcro'd to plywood plates and zip-tied to a thin piece of foam and so forth. Then vibration causes a receiver to break and they blame the receiver.

I think people need to get back to good installation practices.

RE: ONE RECEIVER OR TWO??
 

Very well said. I was having just this same conversation this past Sunday. A fellow at my field has his batteries zip-tied directly to his wing tube in a 33% plane and he has his dual receivers attached with velcro to the floor of the plane. No foam in sight.

A plane I recently purchased was the same. Batteries in direct contact with the frame of the plane. Seems to have become a very common practice. A little foam goes a long way towards eliminating many of the "failures" that people have.

Yeah, and those same two gentlemen, WHEN they crashed those two planes would blame it on the radio.

Poppycock, that's builder error.

RE: ONE RECEIVER OR TWO??
 

Well I totally agree that a proper installation is absolutely necessary. If you do stupid stuff like strapping your RX to a wing tube or wooden former with no foam cushioning at all you are just asking for a failure no matter what or how many you components you install. As for my position on this two vs one deal, when Mike Hurley writes that people who install two rx are "ignorant of the facts" I get pretty pissed! That is an ignorant statement in itself. And to be honest it is really beginning to sound like a JR company line.......... whether it is true or not.

Obviously there are plenty of guys running both setups and having success. My position is that the second receiver gives me an OPPORTUNITY to possibly save my plane if there is ever a rx failure....that is all. I do it purely for redundancy and that is all. As Doug stated before, as long as you are willing to risk the single point of failure than one receiver will obviously work fine. I am personally not willing to risk it no matter how small the possibilty may be.

Then you're using 2 receivers for the right reasons.. My problem is there are a lot of people out there saying you MUST run 2 receivers because of current draw or whatever.. and that's simply not true.

As for saving an aircraft when a receiver failed.. I've done it myself on my old Carden 41% Giles G-202. It wasn't actually the receiver that failed.. but the receiver lost power when the switch failed and I DID land the airplane on half the airplane operating.

That said.. I DO believe I get better reception using only 1 receiver. People can choose to believe my opinion or not.. it's up to them.

RE: ONE RECEIVER OR TWO??
 

Doug,

More often than not it is the switch, and most people blame the receiver.

RE: ONE RECEIVER OR TWO??
 

I do agree with you Doug.......one receiver should have no problem with the load of 10 or so servos. And yes some people do experience failures that are falsely attributed to the receiver, but there some instances when the rx did indeed fail and a second one gives you a fighting chance. But in the end you have to do what you are comfortable with.

Actually.. a stalled 8611 will generally pull around 2.75 amps until it burns out. So 10 of them could possibly be capable of roughly 27.5 amps if you could somehow manage to stall all of them at the same instant. JR receivers are quite capable of handling up to 60 amps in bursts (although I don't recommend trying it) so the receiver seeing high current isn't an issue.

RE: ONE RECEIVER OR TWO??
 

this may sound dumb but does this mean that if you had a 2750ma battery and a fully stalled 8611, that it would take an hour to run down the battery?

or am i mistaken about how amps and stuff work?

could someone fill me in?

RE: ONE RECEIVER OR TWO??
 

Sort of.. since a battery will drop well below a usable voltage before you run it completely empty.
