Official Freewing Twin 70mm AL37 Airliner Thread

[xviper]

Hello to everyone, I have done my maiden last week using a Graphene 5000 45c 6s lipo Admiral 10ch receiver with a satellite.The plane take off , fly and then land safely ...Only one problem...I could not activate flaps with my SPEKTRUM DX9 BLACK.3 people at the field try to help me but really no one has solved the behave.Problem is that when i activate take off flaps , all the 4 flaps do not move together and at different positions and speed.When i activate landings flaps again they are not synchronized and stay all 4 in different positions.When i put the switch to zero position they all come up at different speed and not together.You can imagine that not using flaps for landing in this airliner is a problem it came fast...I check the blue box but it seems that all connections ar correct.Can someone please post a picture of your connections to the blue box ? I don't want to risk flying again without flaps and really want to sorted out the problem maybe due to a mistake by me...Regards

Re: Flaps.
1. Are all the rods in the same hole on the servo arm and control surface horn?
2. Did you tell the TX that you have "1 AIL, 1 flap" in the aircraft (wing) type?
3. Did you go into the flap menu and do all the settings in there? And assign to the desired switch?

Fredardi: Also try not to deploy the flaps and the landing gear at the same time as I've read where others have had issues when doing so.

With your assembly manual there was an insert showing all the ports.
Also check the connectors where the flaps plug into the ports on the wing.
If you removed the connector on the wings to fish the motor leads the flaps (and all other plugs) could have come loose.

Tom

Well i believe the connections of the wings are not loose because all servos of the wing work but flaps all 4 are not synchronize when you activate the and they stay at different position all 4...I will double check again...Maybe is the blue box ?Thank you for your advise

If I use just the mix to turn off the steering it rotates to the left or right before the gear retracts
Tom

That's really odd. It shouldn't happen. Some setting is a bit off.

[I-fly-rc-aircraft]

Your mix 2 alone should have turned the steering off when the gear is up. Your AUX2 being operated by RKnob may allow you to trim anytime you want to but I find that doing the trim on the steering using the sub-trim on AUX2 is fine. Once you've got the plane rolling straight, you should never have to do it again - at least I don't. With the RKnob in play, if you change the knob for some other plane (like for master gain), then you have to trim it every time.
So, I take it that you're using switch G for the retracts? What do you use for throttle cut? G is fairly standard for throttle cut. Does your switch A turn the gyro on and off? That's the standard one for retracts.

If I use just the mix to turn off the steering it rotates to the left or right before the gear retracts, which would be fine if I didn't have the dual landing lights on the strut.
I was using Rknob for master gain but can't now. I mechanically adjust my steering to go straight so I just have to make sure the knob is centered.
Switch A is for retracts and switch H is Throttle cut, which is what I use on all my planes. Switch G turns the gyro on/off. The stabilizer uses the gear data.
I have each surface on a separate switch for my rates for now (B for Elev,C for Ailerons and F for Rudder). Once I get the rates where I want them I can combine two or three surfaces.
Flaps, of course, is on switch D.
Every switch but I (bind button) is being used and if I wanted recovery mode I would use that.
I've not had to use all my switches on any of my planes until now,
I almost need a label on each switch Lol\

Love the angle and is that a 3d printed pod made for the runcam? Would love to try that out with the stabilization of a gopro7, but I wonder if the height/foward facing square shape would cause too much drag.

Hello, yes this is a 3D-printed mount specifically for the Runcam camera, the file is available on Thingiverse for free download. I posted a link but moderators removed it (not sure why, since its not for sale) Anyway I have used it on several planes, including my Radian glider. It does create some drag but its quite minor and not noticeable. The mount has a hole in the back so air can flow through. It is the exact size for the Runcam and a different camera will probably not fit.

P-mix 2 : Rud> Ax2
Rate....100%.....100%

Switch...Switch A

Mix 1 is to allow me to turn the stabilizer on/off via a switch. Switch G.

This is the only way my steering servo will not steer when the gear is up. Note: even though my Rud to Aux2 is assigned to Switch A (Gear) The Rknob turns off the steering.

One benefit to this is now my Rknob will trim the nose steering without affecting the Rudder trim.

Ok, so after pulling out my last hair this is how my DX8G2 tx is set up. Keep in mind I'm using the Admiral rx600sp which is a 7 channel rx using the bind/aux2 port.

He only needs 7 channels. AUX2 (ch.7) on a RX600SP can be used if not using gyro.

Got it. I didn't know that the 600SP had a 7th channel. I see now that the "bind" port is also the AUX2 port. He's good to go. He just needs to know how the do the mix. Here's one of my mixes to get the steering working via the gear switch:



Note that the switch is whatever you use for the gear. Mine is "A". Yours may be different.

I'm using an RX600SP rx. I'd like to be able to have the steering off when the gear retracts but I'm pulling my hair out trying to get it set up on my 8 ch tx.
I have the first 4 channels as usual T,A,E,R. 5 is my gear, then Aux1 is flaps. I have the steering servo on Aux 2.
Almost to tears here trying to get it to work.

Tom

You can't use AUX2 (ch.8) for a servo* when you don't have a channel 8 on the receiver. Your RX only has 6 channels. You say you have the steering servo on AUX2 BUT what's it plugged into on the 600SP? *If it's anything like the Lemon equivalent, Ch. 8 can be used to control the "master gain" of the gyro even without a 8th port but that's a different scenario. To work a servo, it must be plugged into a port.

[Spinny Testaverde]

Thanks guys! This was with a run-cam 2 (available from Motion RC) - mounted to the bottom rear of the fuselage with a freewing weapons mount (the camera is sitting inside one of these)

Love the angle and is that a 3d printed pod made for the runcam? Would love to try that out with the stabilization of a gopro7, but I wonder if the height/foward facing square shape would cause too much drag.

[MikeT]

I installed a double landing light on the nose strut and it binds when it's retracted so I'd like to keep it from turning when retracted.

That explains it.

Mike

[I-fly-rc-aircraft]

Heres my landing light

[I-fly-rc-aircraft]

I'm a believer in if it ain't broke don't fix it. Since it's not binding and working as designed I'm leaving it be.

Is yours binding up when retracted? Or are you like me and want to be able to adjust steering trim separate from the flying rudder? I'm using a Lemon DSMX 10-ch. with satellite. A 7-ch stabilizer PLUS would also work and give a little stabilization for those cross wind wing waggles.

Thanks, I'll need to get another rx.
