strange question... Five of us are about to do a 12 hour race and one of us is left handed... is it possible to attach a right AND a left wheel at the same time both being functional ?

(ATL)
Low-side only trim adjustment. Throttle trims on most radio systems are ATL, allowing the trim to affect only the idle and not the high-speed engine's setttings. NOR (normal) is the other option of trim setting wherein trim movement affects the servo across its entire range of motion.

Here are a couple pics of the 4PX manual to have a look at.

http://orangerx.com/tag/surface/

just to kick myself again, c2 is basically hrs mode, correct?

You know the best fastest T-Fhss recv R304SBE, is only 49.99 new right? way cheap and a quality non-knockoff

and knock $10 off that w/ coupon from Tower.
I got 3 for $40 each w/ shipping. ... placed 3 seperate orders w/ the same $10 off coupon for each order! :)

How did you get around individual shipping fees then? I have never heard of tower shipping being free without another coupon or spending over $100 without being a parts saver item or tower club member.

No, there is only 1 set of wire to connect the wheel with the transmitter.

Josh L 06-25-2015 02:48 AM

Well there you go.^ If there is one set of wires all one would have to do is make a switchable y harness from said wires. That may be a stretch for most, but I'd do it if I was in the same circumstance, if not only just to say I was the first to show it CAN be done. Another thing id assume you'd have to do via wiring is to reverse the output polarity aswel from the left hand side. That way you wouldn't need to reverse a channel to correct the steering input direction, unless you just simply set a condition mix you hit as you handed off to the lefty. It's all pretty simple if you ask me. This radio is more than capable to do it to.

lightfoot 06-25-2015 06:37 AM

Thank you guys for that input... I'm going to pass that on to a more competant member of our team :) and see where we go from here... Thanks again...

Help with Receiver
 
Hello - I purchased a 4pk super R last week here. I know, there is a separate forum for it but it gets no traffic. This forum has all the Futaba vets.

In any event, it was used 8 months with a receiver. I just noticed the receiver is a 604 receiver. I'm thinking the owner sold me the old receiver and kept the 614.

Does this make any difference in speed, etc? I race a Tekno SCT410 and am a beginner. However, I'm trying to buy quality stuff to grow with the hobby. I want to get this setup the right way first. I can always use this the 604 in a future basher.

Any advice on buying any other receiver to start with that will bind to the 4pk super R? Is the 614 better? Any advice is much appreciated. J

The 614 is smaller in size, and it can work with 2 cell lipos. When used with a 4PKS transmitter the signal speed is faster than a 4pk.
614 also has a dedicated battery input, instead of sharing the 4th channel, like the 604 does

In the older 3 channel stuff, FS was Futaba code for dual diversity antenna (internal & external) and FF receivers had the single external antenna.

JAE 06-25-2015 08:16 PM

Thanks. So, If my SCT 410 Tekno's motor/esc is powered by a Lipo battery, it won't work. Keep in mind, you are speaking to someone's who's last setup was a 88 Losi JrX2 with a Futaba Magnum.

Hello, I am looking to buy a radio 4px, and would like a candid feedback on this radio.
* Always used Airtronics, my last radio was an M12. When in doubt between M12s or 4PX.

thank you
