Lee Wilson Posted March 14, 2011 Share Posted March 14, 2011 Hi, I have just assembled my first model that has flaps and wanted to program them with 3 different position on the switch of my FUtaba 7c 2.4 TX, is this possible? At the moment I have them on channel 6 using a Y lead and all I can seem to get them to do is go full travel at about half a turn of the dial. What I wanted was a set position of say 10 degrees for take off and 20 degrees for landing. I have searched around and found instructions for a 9c but being a relative novice I couldn't translate these across to my 7Any help gratefully appreciated.Lee Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted March 14, 2011 Share Posted March 14, 2011 What servo are you using? This behaviour sounds like that of a retract servo. You do need to dig into the main Futaba site to find the RC stuff but here is the manual - take a look at page 30...Edited By Martin Harris on 14/03/2011 08:36:59 Quote Link to comment Share on other sites More sharing options...

BB Posted March 14, 2011 Share Posted March 14, 2011 I've a 7c. You have to first asign the switch. The default for the flaps setting is the dial. Go back to your f7c manual. It tells you how to do it correctly. I made the same mistake. It's a question of reading the manual fully. Sorry, but, it is. Quote Link to comment Share on other sites More sharing options...
Lee Wilson Posted March 14, 2011 Author Share Posted March 14, 2011 BB,I can see in PARAMETR area of menus you can assign a switch to channel 5 and 7 but not 6. Quote Link to comment Share on other sites More sharing options...
Vernon Lidstone Posted August 1, 2011 Share Posted August 1, 2011 Did you get any further with putting your flaps on a 3 position switch? Quote Link to comment Share on other sites More sharing options...
Wingman Posted August 1, 2011 Share Posted August 1, 2011 Lots of good futaba 7C programming stuff here 7C including operating flaps/crow with the 3 position switch Quote Link to comment Share on other sites More sharing options...
Lee Wilson Posted August 2, 2011 Author Share Posted August 2, 2011 Thanks Wingman, I did have a read through these and I think the way I connected up the flap servos was causing my problem. I used a y lead with one servo fitted the opposite way round in the wing so they both travel in the same direction to avoid using a servo reverse. Reading through the FAQ I need to put the servos in to channel 1 and 6 and then use a mix. I have been using flap channel and Just dialling In Roughly The Same Amount Of flap Each Time. When I get round to It I will change my servo set up.CheersLee Quote Link to comment Share on other sites More sharing options...
Cyclicscooby Posted August 2, 2011 Share Posted August 2, 2011 Ch6 uses the VR knob as a default.. Have you tried moving your flaps to ch7 instead, and programming from there.. Luv Chrisie.. xx Quote Link to comment Share on other sites More sharing options...
Lee Wilson Posted August 2, 2011 Author Share Posted August 2, 2011 Certainly did Chrisie but you can't assign the 3 position switch. Reading the FAQ section of the website that Wingman linked to I need to fit my servos to separate channels and then use airbrake mix. Re reading it's channel 5 and 7 not 1 and 6 as I posted earlier.Edited By Lee Wilson on 02/08/2011 10:32:58 Quote Link to comment Share on other sites More sharing options...
Milan Disljenkovic Posted September 9, 2011 Share Posted September 9, 2011 Hello there, first i need to apology if this is a off-topic but i really need help. I have Futaba 7C transmitter and i i'm building airplane which need all 7 ch, the problem is this: if i use R617FS receiver with 7ch. One ch is battery, this means i now have one ch less. Is there any way to use all 7 ch without battery taking one ch. Or is there any 8ch compatible receiver with my Futaba 7c so when i use one ch for battery i will have 7 free ch. Thanks a lot !!!

Martin Whybrow Posted September 10, 2011 Share Posted September 10, 2011 Milan, use a 'Y' lead on channel 7 and connect the battery to one side and the servo to the other. You can cut out the yellow wire on the battery side of the 'Y' as it's not required, but it's not essential to do so. Quote Link to comment Share on other sites More sharing options...
Phil Cooke Posted October 28, 2011 Share Posted October 28, 2011 Im struggling with my 7C to get the flapperon and crow mix I need on a new glider with a 4 servo wing. This is the blurb from the Futaba website... Ive followed this to the letter, but something still isnt right.... "First you will need to plug your flaps into channels 5 and 7. Next you will need to activate Flaperons. Then go into your air brake menu and activate it, again setting the percentages as needed. Now you will want to go into your Elevator/Flap mix and activate it. Select your 3-position switch in the up position for this and once you have set your percentages as needed, you will want to make this active. Then we will want to do two Pmixes. The first one will be OFS as master, to channel 5 slave, put this on your 3-way switch in the Down position, and set the rate to +70%. The second one will be Offset as master, to channel 7 slave, again put this on the 3-way switch in the Down position and set the rate to +70%. Now you will want to go into Para and set channels 5 and 7 to Switch B if you would like to have Flaps alone on a switch. This will give you the following. 3-way switch in the Up position will give you some Flap with your Elevator, in the Center position you will have normal functions of all channels, in the Down position you will have air brake with up flaperons, down flaps, and down elevator (can be changed to up elevator if needed). Switch B down will give you full down Flap. "Edited By Phil Cooke on 28/10/2011 20:03:21 Quote Link to comment Share on other sites More sharing options...
Phil Cooke Posted October 28, 2011 Share Posted October 28, 2011 What is ACTUALLY happening is as follows When the 3 way switch is UP – both flaps go UP to full deflection, the ailerons mix correctly with the Elevator as per intent – but why do the flaps go UP? When the 3 way switch is MIDDLE – all operation is ok – all flying surfaces reside neutral and work normally When the 3 way switch is DOWN – ailerons go UP and elevator compensates as intent but FLAPS DO NOT GO DOWN – they stay neutral. Switch B works as intent – full flap down/up. Ive tried all the parameters I can and double checked all the connections, I cant understand how to resolve the 2 issues that do not meet the set up design intent (listed in RED) Is there anyone out there that can lend me some advice on the 7C - (dont say use your 9C! ) as Ive still not got my 2.4GHz pack for that one yet... Its clearly close, but not quite right, as I still need to operate 2 switches to get into CROW configuration with ailrons UP and flaps DOWN.Edited By Phil Cooke on 28/10/2011 20:02:01 Quote Link to comment Share on other sites More sharing options...
Phil Cooke Posted October 28, 2011 Share Posted October 28, 2011 ok sorted the first problem, using 0% travel on UP for the 2 flap channels 5 and 7... although I think Im masking the problem rather than fixing it - but its functional - so Im still left with the flaps not going down as part of the intended CROW brake setting... the 2.4GHz conversion module for the 9C (a much more capable set up on there for gliders) is looking like it migh tbe going on my Christmas list...

Wingman Posted October 28, 2011 Share Posted October 28, 2011 Phil I have flaps and crow on my Glens Maule set up as per the futaba 7C instructions but I had to use a reversing Y lead like this which is due to how the flap servos are installed. Sorry I can't give you programming details as I'm miles away from my tranny. Quote Link to comment Share on other sites More sharing options...
