Thanks very much explaining the flap setup. I’ve been driving myself crazy.

[@FatGuyFliesRC]

Glad to help

[@geofkane2365]

Very helpful and practical guide. Thank you.

[@FatGuyFliesRC]

Glad it was helpful!

[@cdodandeniya]

Nice

[@FatGuyFliesRC]

Thanks

[@craigflowers7884]

Thank you for the video, I just got my first jet with flaps using an ar630 and was wondering what i needed to do to set it up

[@FatGuyFliesRC]

Glad I could help. JUST FYI the flaps have nothing to do with forward programing.

[@lewandlo]

Finally someone tells how to hook up the servo leads and how they operate. Thank you so much. I have a cheap T6A -V2 turnigy radio. I just bought it and they were out of stock of the USB cable that connects with your PC. I wonder if you can just use lets say channel 5 or 6 for flaps and you don't have to configure it on your PC? Any help out there?

[@FatGuyFliesRC]

At the very least hook it up and see. I dont have any experience with that type transmitter. so I cannot advise sorry

[@rogerhartzell544]

I have a very important question. I have a Dx8 transmitter, and I have the carbon cub S2 plane . I took out the flight controller A3230A receiver that came with the plane and put in a spectrum AR 631 I then binded it..elevator is working. My rudder is working. My throttle is working even my flaps which I have on channel 6 Aux 1.. did everything like you said by watching all of your videos. The only question I have now is I have two Aileron arm servos one right and one left i..my receiver only has one output for the Aileron switch. What do I do to get right and left working on one switch? Do I get a Y connector and tie them both into the same switch, any information you can help me I would be so grateful I’m doing everything by watching your videos and so far so good except not knowing how to do my Aileron arms ?

[@FatGuyFliesRC]

Yes stick the ailerons on a y they should work correctly then.

[@irwinwka]

I’ve got a dual servo flap system. The travel is different when I use the three position flap switch. Do you know how to adjust the throw for one of the servos.. maybe if I reduce the total throw on the one with more travel they will be closer at mid flap?

[@FatGuyFliesRC]

If I remember right you mix them and enable trim on the mix screen.

[@corbinboczar5329]

Good tips! I know this is an older video but is it possible to adjust the flap trim individually? I have a Turbo timber Evo and one flap sits slightly lower then the other causing it to drift off to the right only when flaps are deployed. Any good fix for this or maybe its normal?I'm assuming there is some kind of adjustment inside the wing under the stickers where the servos go but I really dont wanna rip all my stickers off and ruin it. The only other option i see is maybe adding some tail mix to adjust for this but im curious what you would do?

[@FatGuyFliesRC]

Adjust the clevis in or out manually to even them out . You should not have to open anything up.

[@BillKisel]

Flaperons next video? 😊

[@FatGuyFliesRC]

Well I know how to make them but not enough experience with them to make a video.

[@kmatch1]

What type of plane and what are you planning for flaperons? It may be something I’d do for a video in the future.

[@richardhensley8281]

That’s your seating on your commander on the flaps, ?

[@FatGuyFliesRC]

With the commander i would have gone with the manual. I dont remember what they were of the top of my head.

[@gleng9286]

Have a question on the Tower Hobbies ASW 28, Should the glider be slightly nose heavy, slightly tail heavy. or balanced somewhere between the two? Thanks

[@FatGuyFliesRC]

Always balanced in between but gliders should climb a little when given throttle.

[@BruceWitt-cu1rw]

Hey big guy liked your video with the Tasman xfly so much I bought one. I have a problem I cant get the ailerons or flaps to work. Think I might have stuffed up the wiring or something. I would appreciate if you could give me some of your expert advice. Desperate!!

[@FatGuyFliesRC]

Make sure the servos leads are connected correctly they all connect light to light darhk to dark. Also the y supplied for the flaps my give you some issue . Insure it was connected correctly with the polarity. Again light to light dark to dark. The now single flap lead should plug into your flap channel and now single aileron lead plugs into your aileron channel in a Spektrum receiver its is channel 6 for flaps and channel 2 for ailerons. If none of this helps take the wings off again and test all four servos in the wings with a servo tester. Trouble shoot from receiver to servo and the entire wire road in between. I hope this helps. it is more than likely something simple and staring you in the face. Walk away and come back later. Sometimes I have even disassembled the model and started completely over. More often than not I discover something I missed or ignored that was actually important. I really hope this helps you.

[@HORRUS29]

I have a tactic TTX650 and I'm trying to setup my flaps on my p-51. The manual calls for takeoff to be 27mm, and landing 60mm. I have a deflection gage that tells me how far they are moving in millimeters, but I can't figure out how to change how much they are moving in my transmitter. Could you help me out?

[@FatGuyFliesRC]

I have the same issue when the manual gives millimeters and not percentages which is the way most transmitters are setup. you must put the gauge meter on the control surface and just keep eyeballing it until your percentage is spot on to the manuals info. Sorry but I know no other way.

[@rogerhartzell544]

Could you please tell me what receiver you have in the carbon cub 2? Is it the ready to fly receiver that was in it or is it a different receiver? Any info you can give me I sure would appreciate .you.

[@FatGuyFliesRC]

I actually have an old Spektrum sport RX a ar36a that only has as3x. no SAFE.

[@kmatch1]

My experience with 1 cub s2 with factory controller A3230A was different than all other planes. Flaps/aux1 default to channel 6 on the tx. The s2 controller wanted flaps input on channel 8 and since spektrum nx10 wouldn’t allow a channel reassignment on aux1 a common fix is to use a mix and ignore the flap page. Yours seems different than other cub s2s.

[@FatGuyFliesRC]

This video was about the principle of setting up flaps. However in my carbon cub S2 I removed the stock flight controller and receiver and installed an older ar36a sport receiver from an destroyed sport cub s2. So a much more basic setup.

[@xfilesseasonteneponeandsix8346]

My e flite valiant has some bulges in the one wing from the factory and the servo for the flap on that wing works extra hard and can't get the flap down all the way.. when I bring it down all the way manually plane unplugged it bounces back up a bit on its own.. I think the foam hinge is too thick on that one I'm not sure.. haven't flown it yet. Still new. What a pain

[@FatGuyFliesRC]

Shave some of the uneven foam out and reinforce with hinge tape. The flap should move freely manually

[@xfilesseasonteneponeandsix8346]

@@FatGuyFliesRC thanks, I took pictures and working it out with e flite now.. what would you use the shave it down? An exacto knife?

[@xfilesseasonteneponeandsix8346]

They're sending me new wings and servos but will try to shave it down.. they say the servos are on backorder.. will any servo work? I have some spares from a crashed aeroscout.. wife crashed it

[@jerryjones8479]

My father has a cheaper version of that remote without the screen (dxe). His flaps are stuck down in(landing mode) and when I press bind, they go up

[@FatGuyFliesRC]

He somehow has that bind channel assigned to the flap channel.

[@johnraylangstonjohnraylang5924]

Hello I have a old Taylorcraft. W/ no flaps. So I program the DX6I transmitter so I have flaps now but only one side comes down there side go's up. Other then that everything work. Any info. Thanks

[@FatGuyFliesRC]

If they are on a Y lead then remove the Y lead and plug one of the flaps into its own channel on the receiver and assign it to flap also. Then in you transmitter reverse its direction and then they will work together. The other option is to remove one of the servos and replace it with a reversed sevo and they put them both on that same y lead again and then they are both control from the same channel. And the last option but it may require a longer pushrod is to flip the one flap servo to were it is in the opposite orientation of the other flap servo and reconnect it and single y lead also. First option is the easiest.

[@johnraylangstonjohnraylang5924]

@@FatGuyFliesRC Hello Thanks for the fast reply. This Taylorcraft plane has no flaps. I'm using the AILE as for flaps once I'm in the air I can turn off. I'll try what you shared with me but it's not making sense. If I unplug one side then I won't have ALIE. THANKS FOR YOUR HELP.

[@FatGuyFliesRC]

@@johnraylangstonjohnraylang5924 No just unplug the one flap. Leave the ailerons alone. Then if your using option 1 then plug that flap into an open channel on you rx.

[@johnraylangstonjohnraylang5924]

@@FatGuyFliesRC Sorry to brother you.. guess I'm not making my self clear. This Taylorcraft has no flaps to unplug. I heard you can program the transmitter so you can use the aileron as flaps using the flap switch so I program the plane and everything is working? But as I said only one flap going down and the other is going up. So again hate that I can figure this out. See once you switch off the flap switch the aileron work like they should but once you hit that flap switch one flap will go down and the other go's up. It sames the one side need to be revised once you hit the flap switch. Maybe it can't be done until I buy something to revise that other side.. PS. THIS DOSE HAVE A Y IN IT . ITS PLUGS IN AND Y OUT TO EACH OF THE WING. THANKS

[@FatGuyFliesRC]

@@johnraylangstonjohnraylang5924 ok it sounds like they have the Taylor craft ailerons mixed already. who makes the Taylor craft and what model. I would need to look it up to get a better understanding in order to help you. or at least try...lol

[@ChrisDaish-xw8xy]

on my carbon cub s2 channel 1 is empty, Why? and can that be used to plug a set of 30ma lights into? Also is there any way I can have flaps on this model with a NX6 trany? Thank you

[@FatGuyFliesRC]

Yes and yes just don't over load the total voltage or something will fail.

[@ChrisDaish-xw8xy]

@@FatGuyFliesRC thanks, i just dont see how to set the flaps up though. they say you need a 7 channel trany and the nx6 only has 6, but it actually has 7, so how do i set it up?

[@ChrisDaish-xw8xy]

also still cant figure why out of the box they do not use channel 1?

[@FatGuyFliesRC]

@@ChrisDaish-xw8xy Channel one is actually zero and it is the bind channel and to program the receiver.

[@FatGuyFliesRC]

@@ChrisDaish-xw8xy Go through forward programing and pick aux2 and assign it to a switch for safe like B that will free up the rest of your channels.
