RE: How many Jet Jocks are considering dumping 2.4 and going back to 72mhz?
Can't imagine to go back ever 72Mhz or 41Mhz in France, there are tooooo many advantages to be in 2.4Ghz.
But, as this technology is young for modellers, we still have to learnt lots of things about that stuff !

Shulman crashes with JR.....AAGGHHHHH go Futaba!

I fly 2.4, been perfect since day one. Can not say that for 72 mhz and I go all the way back the the days 27 mhz.

PS: I think a lot of peoples problems are they do not show enought respec for the batteries that power their systems. batteries are the weak link in all radio systems bar none.

+1!! I would not put the $$ up in the air, unless I was on 2.4. On 72, you have too many Seniors with Senior moments here in Florida that leave their transmitters "ON" in the impound........been there, had it happen a lot, done that! Not to mention liniar power amps from construction machinery that has been around a couple of the fields that I fly, that have shot down 72mhz. Batteries and switches are still the weakest link in the operation of these models. I do fly JR12X and extremely happy with it. I also think there is a carelessness on working on your planes with the JR system of accidently having big thumbs while inside of any plane and accidently pulling out the little satelite wire extention. This is why I safety tie them with thin thread. Remember, if one of the satelites have come undone, due to accidently pulling it half way out, then if there is any vibration, (yes, I know jets don't vibrate, but they do on take off and landings,or rough air) that pulls the wire the rest of the way out, the main reciever system is NO LONGER the same reciever that was bound to the transmitter. So, it goes into lock out or brown out. I have lost a prop plane due to that lesson.

Ialways stick my little antennas outside the fuse... not pretty BUTyou can't see them when flying and ROCKSOLID
Ialways use some sort of dual battery system... duralite is a winner with 2, 5200 mah EXB batteries on big planes and 2600's on small ones
PERFECTIONHASBEENACHIEVED!!!

Been flying JR 2.4 since it was available, never a problem with 12X and JR gear BUT, all the talk on here about people having many good flights and then an unexplained failure has me spooked so, I decided to invest in Weatronics as I do believe it is currently the best system available and if it does fail, I'll have a record of why and when it did. Just got it installed in my CARF hawk. Looking to try the new gear this weekend.

Three Weatronic systems running well, nice to know what is going on in the plane.
MY other three jets run on 12x/1221 rx with dual battery (LiMn)supply/backup (SmartFly) with ZERO problems on 3 jets.

Nice thread. After reading some of the posts, I thought maybe I can find here somebody interested in switching back to film (no more chips to worry about). I have some Nikons I could sell:-) Might consider trade, I would accept old 2.4 systems as down payment...

To all : please be careful not to fall down to this old brand war...
Concentrate hundreds of 2.4Ghz transmiters on the same airfield is a good way to test and find such problems... This should have probabely not occured if we have twice or triple frequency range disponibility... Who nows ?
Futaba says : you can switch on 80 Tx on the same time and fly !
Spectrum says : you can switch on 80 Tx on the same time and fly !
Graupner says (with HOTT) : you can switch on 100 Tx on the same time and fly !
And so on !
But what appens when you have 80 Futaba + 80 spectrum + 100 HOTT + ... + ... ???
We don't know that ! Seems at a moment there's not enough place for everybody Tx information to go in a correct way to the Rx that lock out !

With 2.4, I have seen too many Voltage regulators go bad at our field (not inculding the Castle BEC crap), soo far within the last year, that would be 4 or 5 regs that went bad and planes have gone in, mostly large 3d gassers drawing lots of current. So i would have to say it's a power issue for most of the 2.4 crashes that i have witnessed.

Maybe, but I think firmly that for this Shulman crash it is not the case : This is not his first CARF UL jet he has built and demonstrated, so for sure he had use the same known and working configuration as the last one. This guy is a show performer with good sponsors/patners that help him to have the right stuff in his plane. A good show performer is sure of her plane performances and reliability before to fly hard beyond the crowd... That's my advice. I've worked to be a show performer for events like that, and I always took great attention to the reliability of material demonstrated, because you have no permission to error...

No he didn't ....read the post.........he admitted installing it over some kind of mirror or reflective material

I'll keep my 72hz in mine. Never had a problem with it yet, all these years,and never will. I also got way too much invested in it to ever even think of converting over. I dont trust those tiny antennas either, def prefer the long ones by far!

I won't go back to 72 mhz ..... simply because I think the chances of a lock-out are less than the chance of someone turning-on accidently and shooting me down. It's that simple (to me).

2.4 is so much better I am amazed at the question............. Why dont you sell your cars and go back to walking with a club and a hairy back

Evidently it's not since there are a hundred threads on all the airplane and helicopter forums discussing lockouts recently. I flew for years with 72 mhz (Futaba FKG gold radios) and honestly can't remember having one radio issue. I've had plenty of "lockouts", brownouts or whatever you want to call it recently with Spektrum and have since switched to Futaba 2.4 FWIW, I still fly FM as well, they still work awesome.

RE: How many Jet Jocks are considering dumping 2.4 and going back to 72mhz?
Our field has been in an up roar about 2.4 lock out problems. Three giant scale planes have been total loss. After looking into it, a couple may have been related to voltage issues. We did some testing. With a fully charged A123 at 6.6 volts running though a JR switch and a short extension, all were 22 guage, with a 2 amp load from a standard field checking device the voltage dropped to 4.7. With the A123 plugged directly into the load checking device the voltage dropped to only 6.1 volts. Now imagine what 8 5955 servos in a snap roll might do to voltage. I would be interested to know how many people have lost a plane due to lock out and was using a power expander like a Smartfly. I know that on my 35% with 2 power leads going into reciever from an A123 the voltage drop was around 1.3-1.5 volts according to the Hitec telemetry. This was on the ground with all control surfaces fully flexed. I added 2 more battery inputs by soldering in leads to two more servos. Now the most I see is maybe a 0.3 volt drop fully flexed. IMHO some, not all, lock out problems could be set up issues and not a 2.4 link failure.

RE: How many Jet Jocks are considering dumping 2.4 and going back to 72mhz?
Im not a jet pilot but since going to 2.4 I have loved it in my planes, ive been flying for about 30 years, the only issue I have had with 2.4 was actually in a car were the amp draw on the servo cause the rx to lock out, could this be the issue with the jets? My fix was to put a cap on the rx and that fixed the issue.

Fromoco sells a capacitor pack that plugs into the reciever to even out voltage when a high amp load seen by the reciever. Even has a voltage guage on it.

Oh ok THANKS Iuse powerbox systems, all the heavy duty amp loads go through that... the rx gets clean voltage, Ihave had "0" problems with these
Iuse Futaba...
