Stock Super Cub Receiver 5th Channel?

[jimd0586]

Hey all. I just bought my super cub and am excited to learn to fly a 3 channel.

Once I learn to fly it, I will add ailerons to the fourth channel.

Is it possible though to set up flaps on a fifth channel using the DX4e and receiver that came stock in the Cub? I heard that other receivers will bind and allow a 5th and 6th channel on that transmitter. But will the stock receiver work? I see that it has two- 2 pin ACT connections. Is there anyway these can be replaced to accept servos?

My plan is to model this after a replica bush plane. I will eventually get floats and possibly even lights for it. Ailerons are a must, but flaps would be great as bush pilots use them for short lake take-offs and landings. My thought was that the DX4e should work because the ACT switch is either on or off, just like flaps... but will the stock receiver allow that?

Thanks guys.

I think you'll need a dx5 or 6 for that. On those TX's the flaps switch is channel 5 and works the xport channel by default on the Cub, which can be adapted to work the flaps.

The act ports are for sensors, and I'm pretty sure they can't work servos.

I may be wrong, and if I am then I'm sure a clever type will sort it all out

Sham, thanks for the reply. In the last half hour I received a response from a gentlemen on Youtube concerning this exact issue. While his transmitter looks to be a Dx5, he looks to have used the original Hobbyzone receiver for flaps using the Xport function. What I mean to say is that I think this should still work on the DX4e. It does take some programming skills and a small computer (like a raspberry pi) to interpret the signal from the Xport... but he includes the code. Here is the link to the fella's page. Maybe you can tell me if I'm still barking up the wrong tree here...

Yep, the XPort can be adapted - as I said.. That's how others have done it.

But I think to output a 5th channel from the radio you need a dx5 or above.. I'm not 100% but I don't think a DX4e can do it.

The receiver can, but I don't think (may be wrong) the transmitter can.

You will have to have a 5 channel Tx to make flaps work.....the factory transmitter is only 4 ch. If you install ailerons -you already have Rudder and elevator and throttle the factory 4 ch transmitter you have will have no place for the 5 ch. The 4 ch transmitter has a button to push for the X port, but you would not be able to control flaps with that button on the transmitter, you would have to have at least the DX 5 or DX 6 transmitter to be able to control flaps if installed.
