I just finished putting together a super cub s BNF. I am using a Dx5e radio. I have followed the binding instructions and have rudder and elevator control but no throttle. I do not know if this is related but when I move the rudder to the left the servo flutters. Battery is new and fully charged. Really frustrating as I wanted to take her out for first flight tonight. Any help would really be appreciated. My plan is to call hobby zones tech line tomorrow.

Make sure you have the throttle OFF and the throttle trim down below 'neutral'. The ESC will not arm if it thinks there is ANY positive throttle.
First,re-bind it after you check and fix the throttle position.
Unplug battery.
Switch on the TX.
Put throttle full ON.
Plug in battery > get a couple of beeps > Immediately return throttle to zero/bottom > you should now get arming beeps. This indicates the throttle zero has been verified.
Servo - first check for binding.
If no binding you have a bad servo > replace.
You can try switching servo plug position and see if the 'bad' servo now flutters on the other channel. That can differentiate a bad servo from some other cause.
What brand servo?
Make sure your control direction is right and you do a proper range test before flying.

The servo is stock. I will try the throttle trick. One new question. The dx5e has electronic trim. So when I hear the lowest tone I am assuming that means the trim is at it least. I will also pay close attention to the throttle making sure it is at its lowest point. Will also switch the servos and test. More to follow.
Thanks!

Don't have a 5e and it's been a good while but I think it works this way.
Run it all the way UP, then all the way DOWN. It makes little tones as it goes. Something like 15 tones. I think you can hear the 'middle' which is neutral/zero. Use that or a click or 2 below that.
When you do the throttle setting it learns whatever the bottom position is in and tries to make that the 'new zero'. If you've set the ESC on a different TX and the trim was off then you end up with a problem like this.

Ok these TX sometimes are a pain to bind the instructions are really odd
on a DX5e you have to install the bind plug FIRST ( also make sure the bind plug is in the right slot)
LEAVE RADIO OFF !
Make sure your throttle is off ( down) make sure your trim button for throttle is down [ hint before you do all else you can turn on the radio and make sure that trim is all the way down than turn the radio back OFF ]
plug in Battery to plane
Than hold the Bind Button ->( it is the button on the left Rear Top on the DX5e radio)[ Mode 2]
while holding that button in, than turn on your Radio and it should beep..and in about 1 to 2 seconds let go of the button, it should be bound
it will give some tones and everything should work including throttle.
if not retry doing it again by those same steps
Sometimes if you hold that bind button to long it will not work correctly, and also if you do not hold it long enough
Again these DXe radios can be a pain to bind.
But do it in those steps it should work
But as fly stated make sure your throttle is all the way down ( if you have it to the top your throttle will be backwards-Up will be off and down will be full throttle-I did that once myself )

Thanks for all the suggestions. Tried them all no luck. I was able to contact the manufacturer they are sending out a new receiver board. A slight set back. Should be in the air in a week.

Sorry to hear that, but remember the Radio process when you bind it to the radio after you install, should make it easier. Hope this does not become a pattern for the SAFE-ESC Unit....one talked about panic button not working correct and yours not binding and messed up ? ?? |

I've always said the SC Cub had a kind of lame ESC.

Situation is frustrating but customer service has been very good so far. The bonus was the fact that customer service was available on Sunday. It has taken me 35 years to buy my first RC plane so waiting another week or so to get in the air is not an issue. I will let all know how new rcvr does once I get replacement done. Thanks for the input. I look forward to being part of the Super Cub community.

Hey guys, I am new to the RC plane world and new to this site as well. Thank you to everyone who contributes to make this forum so great! I was reading the binding problem above and comments. I also recently bought a Super Cub S after spending a week with a friends LP. I agree binding is not the best thing in the world. I use a DX6i and this control board seems to absolutly hate it at first. I would like to add something that may help people if they are having a problem with the cub not allowing you to use full flight mode. When i first used mine I tried everything i could to get it from mode 2 to mode 3. On the DX6i it requires two different switch placements. With both switches in the correct place, it still would not work. Hobbyzone could not help me and sent me to a horizon hobby tech. He told me that several people are calling with the issue that their Cub will not go to full flight mode (my panic mode doesn't work either but i'm ok with that). Anyways, In the setup for the DX6i there is a setpoint under MIX 1 that has to be set. The manual states "7. Set MIX 1: ACT; Gear to Gear ACT, RATE D 0%; U + 100%,". I was told to change the U+100% to U+120% and it worked. I asked about it and he tried to explain to me something that i'm not quite sure of but either way it worked. Not sure if anyone else will experience this problem here, but if you do maybe this will work for you as well. Hopefully someone will find this helpful as well. Thanks again guys for all your great questions and all you vets for sharing your knowlege.

New board is in. No throttle response. Have bound plane a couple of times, no luck. Motor tested good. No throttle response when bound to hobby shop tx.

You are either very unlucky or are doing something wrong. Time to get on the phone to HZ and have them walk you through it.
If it doesn't work have them carefully explain why not.

New board is in. No throttle response. Have bound plane a couple of times, no luck. Motor tested good. No throttle response when bound to hobby shop tx. I have the NEW DX5e Transmitter with the 3 positions switch Mine is MODE 2 Trainer switch Back button Top Left ch.5 switch ( 3 position switch) Top Front Left Hi / Lo Switch Right front top corner . The Mode 1 is opposite Trainer and 3 pos switch is on right top and hi / lo rate is on left top corner Anyway just so you know if I say something opposite from yours if yours is Mode 1 version. I am assuming you purchased a Bind and Fly ( BNF) version Plane since you are using a DX5e radio you must stick the bind plug into the SAFE/ ESC unit in the Bind port ( it says bind beside it ) Make sure the Throttle switch and trim are all the way down ( left stick if Mode 2 radio-Right stick if Mode 1 radio) Install battery in plane...the ESC/SAFE unit should flash Holding the trainer Button in -Turn on the radio and it should Beep when the LED lights first come on the radio, release the trainer button the Unit should be bound and the plane ESC will stay lite and it may beep, it may not...but you should have control over the rudder and elevator and then slowly push the throttle stick up and you should have motor power .remove the bind plug then you can turn everything off....it should be fine then. IF you hold the trainer switch to long or not long enough it will not bind. It is almost immediately when you turn on the radio and the LED lights come on, you release the trainer button and it is bound. you said Hobby Shop TX...?? Is it the NEW DX5e Spektrum Radio or something else off brand thing ? Spektrum DX5e  DX5e Manual www.horizonhobby.com/pdf/SPMR5510-Manual_EN.pdf |

Yes, dx5e same unit as the one in your post. No luck. I believe I am the master at binding. Very disappointed. Will contact horizon tomorrow. At this stage just looking to return and get money back.

Strange. They can be a pain to bind but they normally do. Doubt the board is bad twice, where did you get the radio ? Was it one you had and used before or is it one you purchased elsewhere ? Let us know what happens. |
