Looking at a 4 channel ex where I have front and rear Dove planes. Ideally front planes control dive, rear planes control attitude. What’s the process for set up?

Two options I can think of:
1.
CH1: Rudder
CH2: Dive planes linked together (both actuate in tandem). AD2 pitch controller goes between receiver and dive plane servo. Override with transmitter, otherwise planes will work to keep boat on an even keel. This setup means boat will pitch up and down during diving or surfacing, then then level out with no input
CH3: throttle
CH4: ballast
2.
CH1: Rudder
CH2: Front planes
CH3: throttle
CH4: ballast
* Rear planes (on a separate servo) run autonomously through the AD2. The AD2 just needs 5V power, no signal. Front planes pull the boat under. Rear planes work to keep the boat level. In this setup, the boat stay on an even keel (ish) at all times.

I would advocate for option #2.
linked bow and stern planes only works at a specific speed-depth (surface-capture is a phenomena that makes independent control of these two horizontal control surfaces a must).

Option2 is what I’m trying to use. I have an Rx with 6 sets of pins, 4 channels and power, I’ve plugged the pitch lead into the spare slot so it has power. During set up of adf2 it asks you to command full rise on planes. If I’m using power with no signal, do I just bypass that part of set up and push the set up button without taking any action?Next time someone points out it takes 42 muscles to frown, point out it will only take 4 muscles to b1tch slap them if they tell you how mnay muscles you need to smile:popComment

Talking of 6 channel, I picked up this transmitter, it’s unused but had no Rx or manual. It’s not sending any signal to the Rx, at least the servos aren’t moving, but if I turn off the Tx the servo twitches. Any suggestions?2 PhotosNext time someone points out it takes 42 muscles to frown, point out it will only take 4 muscles to b1tch slap them if they tell you how mnay muscles you need to smile:popComment

Wow, I'm so late to the party everyone's already eaten all the chips'n'dip!
What David said - if you're going to go for Option 2 then set up the AD2 with it plugged in to Channel 2 (and with the radio set up if you were only going to be driving the stern planes) and then disconnect after that and reset your Tx for what you need to drive the bow planes appropriately.
There is actually a third option to consider, and this is a mode that I frequently run my little 1/144 KILO in:
CH1: Rudder
CH2: Bow plane direct from receiver, stern planes only through the AD2. Still lets you override pitch with transmitter. Depending on which way you have the bow planes move with respect to the stern planes for an UP or DOWN command you may either get a pronounced pitch change, or a level-bubble depth change.
CH3: throttle
CH4: ballast
The up-side to options 1 and 3 are that you can use the trim function on your transmitter if your AD2 zero bubble cal is a wee bit off. As noted above, with Option 3 you can experiment a little with different setups between front and rear servos - you can make the dive command from your transmitter send both front and rear planes in the same direction, or in opposite directions. One will result in the boat generally pitching up and down more, the other will result in keeping the boat more on an even level at all times. Which you prefer is entirely up to you. (I run my KILO setup for "more pitch", and my OSCAR set up for "more level".)
I'm not sure what to suggest about the transmitter - the twitch you see may just be a function of the proximity of the transmitter to the receiver and not necessarily an indication that the receiver is actually picking up a proper signal... Did the Tx come with a crystal, and does it happen to already be on the same channel as your Rx? If different, which crystal (between Tx and Rx) are you swapping to make them on the same channel? Do you have any other receivers you can test with? Presumably the Rx in question can be shown to work with another transmitter?

I have a 4 channel Rx which works ok with a 4 channel futaba. Test 1 using no brand crystals in the futaba. Rx responds ok. Test 2 Switched both Tx and Rx to use the Carson crystals and no life in the Rx. Test 3 Put the no name crystals into the Rx and also the Carson 6channel Rx , no life , test 4 put the Carson crystals into the Rx and tx again no life.Last edited by Albion; 03-31-2019, 03:46 AM.Next time someone points out it takes 42 muscles to frown, point out it will only take 4 muscles to b1tch slap them if they tell you how mnay muscles you need to smile:popComment

So, it's important to keep in mind that not all crystals are the same, and different transmitter manufacturers use different types of crystals. Where I'm going with this is it's not necessarily a valid test to take the crystal "set" from the Futaba Tx and use it in the Carson Tx, and vice versa. This is even more so the case with receiver crystals, since you also have to consider if the rx is a single conversion and dual conversion type.
Are all of these crystals on the same channel, or are they different? (If the same it will help to be able to mix and match better.)Kevin McLeod - Oscar II driver

Thanks for all the responses , sorry I have side tracked this. I remembered I have an early adf2 which wasn’t compatible with a lot of Rx, wonder of this is the set. Will do some more experimenting. Also the Carson set is put to one side for now. More news laterNext time someone points out it takes 42 muscles to frown, point out it will only take 4 muscles to b1tch slap them if they tell you how mnay muscles you need to smile:popComment

If you're suspicious about the ADF it's easy to diagnose - plug a servo directly into the Rx. If it works you know there's a good signal there. Next plug in the ADF and watch the LED sequence after the power-on self test. If it fails to detect the PITCH and FS signals then you have an incompatible unit.
