Official FlightLine RC 2000mm B-24D/J Liberator Thread

[mshagg]

Having a multi protocol radio I have the luxury of a mix of receivers - DSM (spektrum, admiral, lemon), frsky, flysky. In terms of RF performance I cant say I've noticed any difference. Honestly I think it's 99% setup. Running a satellite/redundancy receiver is simply one solution to address setup. Something with relatively long coax leads on the antennae can help get them where you need them, but in some builds that can also be a hindrance.

Keeping it relevant to the liberator, I was getting low RSSI alarms running an Frsky receiver. Brought it in, adjusted antenna placement, havent heard a peep out of it since. One thing I would consider really important is having the capability to receive signal strength telemetry, so you get a heads up on RF performance long before the link breaks. This is the primary reason I'm pivoting away from spektrum - telemetry is core functionality we shouldnt have to pay extra for.

Agree with Hugh - now all i need is a satellite/redundant thumb for when my primary one fades on me ;)

[Hugh Wiedman]

I must agree with Wild Man I would never fly anything but spektrum. It's personal preference though. I have never had a single issue with spektrum over the many many many years i've used them. But you hear the same argument time and time again about this receiver / radio or that one. Everyone has a brand preference and 9/10 times when people cry brown out it's just them not wanting to admit the mistake they made regardless of radio system.

Agree as well. As much as I don't like HH, I've flown nothing but Spektrum in the last 10 years as well, I now have over 30 Spektrum RX in everything I fly including my 3D Extreme Flight planes, from the AR 636 to AR 637T and a few AR 7350T's, all with AS3X and only had a problem in one EDF, but that was my fault as I stupidly ran the antennae including the active end right alongside of the battery. And even then, it took some 50 flights before it lost a signal. Now I include RF chokes in all high output EDF's and a satellite remote receiver as well. As long as I keep the antennae as far from any wires/power cables/batteries as possible, I don't have any worry about a signal loss. That's not to say they are the best, I'm sure there are others just as good or even better, but for me, they have sure been reliable. I've seen plenty of other pilots experience signal loss, but none with a Spektrum RX with a "clean" antennae placement. I have enough other issues to worry about with the way I fly that the last thing I need to have is a signal loss. My aircraft do plenty of stupid moves from just "brain cell losses".

NO I did not miss his point at all. I will not use either Lemon or Admiral, with a satellite or not They are cheap junk IMHO and I will never use them, You use what you want and I will use what I want. I will not use them for the same reason you will not use Spektrum. I have used Spektrum since they started and have NEVER had an issue with any of the receiver's they have, and sold with planes.I am talking about over 50. That includes many of every receiver they have made. Even if you gave me a Lemon or an Admiral receiver I would just pitch it the garbage can. That should let you know what I think. You like them you use them

I believe that you missed xviper point he was eluding to in that the newer diversity antenna receivers are better used with a satellite to help with more solid RF propagation.
The Admiral 10 channel doesn't have the satellite capability whereas the Lemon channel does. A lemon label is not a bad thing.
The brands are a personal choice much like an automobile. I dumped Spektrum over five years ago because of losses(and over pricing) and switched to Lemons with nary an issue since.
Best regards,

Hey Guys,

The Lemon 10ch and the Admiral RX1000 10ch are the exact same unit, the only difference is the label. "Lemon" or "Admiral" are just brand names, they are the same receiver from the same manufacturer and they both have a satellite port.
As Xviper said, the use of the optional satellite receiver is highly recommended. TLewis95, very sorry to see that happen and I hope that you can carry on!

OOOOOOOPPSSSSS...………..caught me in a chemobrain moment MD and I stand corrected.
I meant the Admiral stabilized don't and the Lemon stabilized does have a satellite port

[xviper]

C'mon, you're too serious man and I'm not as dumb as you might think. We're supposed to laugh. I've understood every word about this topic since I mentioned my opinion weeks ago. I realize it's not a big deal. But I can see you are a man of serious principle and lots of rocket scientist experience. Nothing wrong with that and idiots fall by the wayside. But, you might want to drop the X from your handle and just go with Viper. Many who post on this forum gets a strike from the Viper...Carry On Bravely.

Well, put a smilie in so I know you're jesting. BTW, not a rocket scientist, but I do have 20 years of brain surgery experience (not the human kind).

[quitcherbitchen]

I have had plenty of Bad UBEC (4), Only one bad receiver-Orange with stabilization. I think the BEC is at least as much of a possibility as the receiver if not more. I now have radios that transmit the receiver power numbers and log. It probably won't help in the air, but it has saved at least one plane while testing on the bench.

...."but it gets lost to those with Western thinking".... Aren't you "Western"? You live in a Western province of a Western country. You eat, sleep and breathe Western. You probably have a Western hat; Western boots and Western clothing which, according to this label, means you can't see beyond your own connotations; bias and limited vision...There are two kinds of lemons: Bad products and Citrus fruit. It's a conundrum.....

Please read my reply again. Note the whole sentence: "those with Western thinking AND can't see beyond their own connotations, biases and limited vision". I CAN see beyond the western connotations, biases and limited vision. I CAN see why Asians use the term "lemon" to name something and it has nothing to do with "bad products". That's all I'm going to say about this. It's been beaten to death before. If you can't understand any of this, you never will. Please continue to debate this with yourself.

[TLewis95]

Thanks for the advice guys. I have never messed with Sat Rxs, but will be ordering two, one for this Rx and my next B-24, and one for my F-86 that uses the 6 Channel Admiral Rx.

Everything else I have uses Spectrum AR610s and I have never had any signal issues with them.

[AirHead]

Exactly! I've tried on several occasions in the past to explain the "Lemon" name, but it gets lost to those with Western thinking and can't see beyond their own connotations, biases and limited vision. I won't go into it again.

This is not the first and only case of signal loss and airplane loss for this RX. The equivalent Lemon version can be fitted with a satellite. No satellite, no trust.

...I haven't re-connected anything to try to duplicate it or see what failed yet...

Oh, sorry to see that...looks like an 88mm flak battery placed a lucky shot. You did a wonderful paint job there. I know what you mean about not having enough patience to re-do it. What is fun the first time is kind of tedious the second time. It might be easier to do a completely unrelated livery to keep it more interesting.

[TLewis95]

That's a shame. What kind of radio? Any telemetry or logging?

Dx6 and an Admiral RX1000. No telemetry or logging. Ill rig it all back up tonight or tomorrow and see if I can get power to anything.

[Hugh Wiedman]

Rough day for Little Lil today... Climbing out from a low pass and at some point lost all motor and radio power and got to watch it coast up into a tail slide, and then slowly, but vertically, spiral straight in.

I haven't re-connected anything to try to duplicate it or see what failed yet, but everything seems to point to the UBEC to me since it was a complete, sudden lockout of everything for what had to be about 10 seconds of no-control before the impact.

I will certainly be getting another one once they are back in-stock, but I don't know if I have the patience to re-do that camo scheme again.

I wouldn't rule out signal loss either.
