I have a Sundowner Formula 1 Airplane with a 9C SUPER PCM Radio by FUTABA. My reciever is a R319dps PCM 1024 by FUTABA. On the reciever its showing slot numbers 1 through 8 then it has a slot called 9/B and then it has a slot that says DSC. I have 6 servos on the Sundowner which are high torque servos also by futaba, anyways my question is how does this all go into my reciever ? Example: I have two elevator servos, two aileron servos, one rudder and one throttle servo. The instructions tell me to put the aileron servo into slot 1 on my reciever ( but I have two aileron servos ) then it says put the elevator servo into slot 2
( again I have two elevator servos ) I know where the throttle goes slot 3 and the rudder in slot 4. The instructions says slot 5 would be landing gear ( but I dont have landing gear ) slot 6 the intructions says is FLAPS/2nd FLAPERON, then slot 7 is AIL. DIFF, whatever that is, and 8 is Auxiliary channel. It also says that the battery can be plugged into an unusual slot such as 7 or even plugged into a y-harness with any servo if all 8 slots are in use. CAN ANYONE HELP ME. This is my second plane I have ever put together as a ARF. My first was the ALPHA 40 TRAINER which already had servos and reciever installed when I got it.

When using multiple servos to control a surface that usually only uses one (such as two servos for elevators), the two servos are connected into different slots then "mixed", where one slot is used to control the other as well by making a setting in the transmitter. See this site for a list of Frequently asked questions for the 9c, that should have answers to what slot to use, what settings to make, etc. Your manual, although not the easiest to use ( I have a 9c too) does give answers to many of your questions.
See airplane programming #9, #27 and #40.
Don't despair. It will all work out and you will have much greater control (read finer) that if you use a "y" cable to connect two servos.

P.S. Your lead from the switch (bringing power from the battery) can be plugged into any empty "slot".

Ok you need to plug ailerion in to chanel one and the other in any aux chanel, same goes with elevator . Then u must use a proportional mix on the radio to mix it. You would be better off getting help from an experinced modler at your feild, its hard to program a radio over the internet

Channel 1--right aileron
Channel 2--Y harness to the elevator servos
Channel 3--Throttle
Channel 4--Rudder
Channel 5 empty
Channel 6-- Left aileron IF you want to set up flaperons (ailerons that can also function as flaps)
Channel 7--Left aileron IF you want to program aileron differential (more UP throw than DOWN throw, helps with adverse yaw)
Channel 8--empty
. The battery can go in any unused channel (9/B is the battery channel, normally).
You might be able to use CH 8 for the other elevator servo, and program a mix, but I'm not sure how, or if it's worth the hassle.
I would recommend using channel 6 for the left aileron; you can still program differential by another method. The 9C manual has all this in it.

Martin, this is ALL covered both in the owners manual and in the book you got from Tower that we discussed in your previous thread. It DOES take some reading and some tinkering to figure out.

What Bruce88123 said: it's in the manual. If you don't understand the build and hook-up you won't be able to trim it.
Treat yourself and get the Harry Higley book on Programming the 9C. WELL worth the price and much simpler to follow than the manual.

I am currently working on this very plane for a RCU review of the Sundowner. Hopefully the weather will let me fly this plane this weekend as I'm really looking forward to getting it into the air. It appears from your posts that you don't have a lot of experience flying planes yet (also from the fact that this is being posted in the beginner's forum). I'll tell you this much, THIS IS NOT A BEGINNER'S PLANE. If you're still pretty new I would put the plane up and wait until you've got some more experience. Working with dual elevetor servos does present some challanges in your radio setup. You can't simply use a Y-harness as was mentioned above. For dual elevator servos you have to use either a reversing Y-harness or a computer radio that is set up to mix for dual elevator servos. You can use a standard Y-harness for the ailerons though. You don't need to put the aileron servos on seperate receiver channels as you DO NOT WANT flaperon setup on this plane. You'll want to avoid 3D type throws and setups as this is not what this plane was designed for.
Another factor to consider if you are still pretty new is that this plane is designed for one thing, and one thing only, TO GO FAST. It's a racing designed plane and it is going to be fast in the air. Fast planes and inexperience equal to one thing, a big pile of broken balsa. And considering the plane here it will be an expensive pile of broken balsa too.
Once again I urge you to reconsider if you are still pretty new to flying.

Martin,
Quite frankly, you have no business attempting this project. You've thrown a bunch of money at a model that is way over your head. If you proceed with the normal progression of steps that most beginners follow, you might be ready for it in a year or two. Otherwise, you will be a hazzard to those around you.

OK guys, he already acknowledged in another thread that he is a LOOOOONG way from flying this plane but that doesn't mean he can't build and admire it.
Let's ease up on that part of it a bit.

THANKYOU FOR ALL YOUR COMMENTS AND ADVICE. I know that im way over my head with this plane but like Bruce said I have started it and im going to finish it put it aside until im ready for it. Due to my lack of expirence I saw the plane, fell in love with it, had to buy it, not realizing how much advanced it was for me. Im going to finish it because I have alot of money into this plane already and hopefully one day I will be able to fly it. Again I appreciate everyones help . . .
