Apparantly the R142JE Rx that comes with the 2PL is non-BEC.
Does this mean it will need its own batterys? surely not?

I thought it was BEC.
Pretty sure it is, I'll check next time I see one.


Non-BEC just means you have to feed it 6V not direct 7.2V. If you use any ESC then the ESC does the BEC anyway, ESC has a built-involtage regulator to feed the RX its 6V.


Biggest impact would be on newbies trying to use 2 servos - the little red plug is wired direct to the 7.2V battery.

I thought it was too but I saw on one site an asterix next to the
model number of the Rx and it said it was non BEC
Is the Rx overly large by modern standards ? or... would it be
smaller than my 20 year old acoms?

It is reasonably small... about 25x35mm I think.


Slightly smaller than the previous 122JE which is about 30x40mm. Super reliable unit, got heaps of those in my fleet. Open up the case and the PCB's just about 1 single DIL chip -Futaba could have easily made the PCB & case a lot smaller.


122JE is definitely BEC, maybe that's why they're still making that and giving it with all the basic stick & Magnum radios.





If you wanna spend a few bux more, check out the new Futaba A3PM FM w/10 model memory!



No I haven't seen it yet either.

Hmm ok
Radio kit is one thing i have not REALLY delved into since my return
to the hobby.
What are the advantages of a dear radio over a cheap one
I understand EPA and ABS and can see use of that, synthesised
frequency adjustment and use of 40mhz and FM, also multi-model
memories, but what else can they do that i cant do with my old stick
radio that will make a difference to the way the car drives/i drive the
car?

Short answer - NONE.








EPA is handy if you can't be bothered finetuning your linkages. But if you're an old-timer you'd be used to doing it anyway, no biggie for 90% of the time.


Hell, we lived RC before "servo reversing switches" too.



ABS, don't even bother.


Synth freq is useful if it saves you buying xtals, but all your RXes will need to suit.


FM is good if there's heaps of others running too as its more selective and less chance of interference. But it don't solve glitching if your own car is RF dirty. Plus FM xtals are more expensive & complicated.


Multi-model memories... yeah right... you still have to buy servos & RX for each extra model and has anybody priced them up?? Buy them loose for AM (eg the 2PL) and you might as well just buy a $80 stick set as it'll be cheaper; FM RXes are like $100+ alone.Might as well just buy a basic radio set for each car.


(When we took like 6 cars to the track when ausmicro was there, they all each had own radio & everyone could borrow to play at the same time. Jeez they had fun with the Minis!!)





Stick vs wheel <== your own choice

Cool so really there is not much point going past say a 2PL?
I would rather have a tx for each car i have, so they can be driven at
the same time (eg if a mate comes around and you want to race or
whatever)
I do prefer wheel to stick, but i just happened to have the old stick
set. I think I am the only person at STMCC with a stick radio, aside
from the Club Car which is a beaten old TL01 which may even have
the same radio as me.

I'd prefer to hold out for the 3PM, given that its FM and its got 3 channels.


Never know when you want a 3rd channel...



FM RX & xtals alone would be worth $100 more than the 142JE haha.


I'd buy one if I weren't a KO freak.

Oh for the mechanical arm that flips the car over onto its wheels when it rolls

Lights and horn, oh yeah baby.



Not sure if the 3PM comes with a 3ch RX though.... but the TX is definitely 3ch. Either way just $100 premium for FM is tempting; the TX's other specs are pretty much lineball with the 2PL.





Futabas are decent gear but somehow KO just has that special cachet, don't know why. Have been using EX-1 since 1982, majority of our wheels are KO & love 'em.

I keep forgetting to reply post here, but yeah confirmed that the RJ142 RX DOESN'T HAVE BEC.


So that means CANNOT CONNECT DIRECT TO 7.2V, max is 6V.
