How are your flaps set up?

[FunCubParts]

There are many different ways to set up the FunCub flaps, primarily the solution to get your flaps to move in the same direction since the servo insets are opposite, such as similar to aileron servos opposing movement...

I used the flip the servo and a z bend wire to control horn, worked great, am building another cub, am going to try a servo reverser. Will report on that after tested and used.

I had a 6th channel, so I used it to slave gear to flaps and do it that way. It was a pain in the butt to set up, though. Next time I'm going to use a servo reverser and be done with it.

I was stumped with what to do as I've only been flying for 3 months now, but I'm using a Futaba 7c and used channel 5\7(reversing one of the channels) and the air-brakes function on the 3 position switch so I have 0\50\100% settings adding down elevator accordingly. Seems to be working great.

I use a a y reverser and then plug it into the GEAR on my receiver. I have the elevator set to give me 20% DOWN whenever the flaps are used. I have a SPEKTRUM DX6.

Why don't you use the Aux channel and use the flaps switch? Are you using Aux for a separate aileron servo, one aileron on aileron channel and one aileron on Aux?

I don't know why I use the GEAR switch. Thats the way my friend set my first FunCub up on my transmitter so I been doing each one since then the same way. It works good and I'm used to it. The bad part is that the flaps are either full on or full off when you throw the switch. Some day I might like to get them to be gradual but not yet.

You are right about the throw on the flaps using the gear switch. We had to use gear as we were using two channels for aileron, the aileron channel and the aux channel, each aileron servo had it's own channel. You can change the throw on the gear channel, but only to approximately 1/2. (We also have a DX6) However, if you are using a Y harness for aileron, and therefore only using the Ail Channel for Aileron, plug your flaps into the Aux Channel, and the flap switch will operate the flaps, the benefit being that you can adjust the throw on them from 1% to 100%. When you plug it into the Aux and flip the flap switch the first time, nothing will probably happen, leave the switch on and go to the percentages window on your screen for flaps, as you turn the wheel on your TX you will see the flaps start to move down accordingly, when you have a percentage you like, set it, and the flaps will be adjusted to that percentage throw. If you call Horizon Hobby their Techs will walk you through any set up on your DX6 you may desire. The Aux (flaps) channel is more adjustable than gear, it really works better. On the DX8, you get two flap settings, you set yourself as you prefer, and flap speed, anything from slam bang they're down like on the DX6, to very slow scale like movement.

I'm using a Futaba 7c as well and use a reversing y harness from HK controlled from the rotary knob on the transmitter because, like vegasdave, thats where my buddy initially set it up for me! Originally I wanted to move it to the three position switch but now I've grown used to the knob and can roll them up or down as fast or slow as I want. Also, my three position switch is now committed to (the soon to be installed) Eagle Tree Guardian to select between 2D-Off-3D. Several people have said it's just something else to fail (the reversing Y) but to date I haven't had any issues with the unit and would recommend it. I also have the elevator set to give me some down (15%) whenever the flaps are deployed.

Good morning Robin. Don't forget to eliminate mixes when you have the Guardian installed. Boy it's a cold mother today.

Thanks Merv,

I'm glad you mentioned something about that because I must have missed it!  I'll have to reread my documentation and make sure I didn't miss anything else.

I have a DX6i and initially tried programming mixes with one flap on the aux ch and the other on gear. I thought that setup would require a reverser but happily found the gear channel didn't need reversing. Unfortunately, I couldn't manage to program what I wanted with two mixes, three flap positions. Among other problems, I could not get the gear channel travel to match aux travel when shooting for 40%. It was a little better at longer travels but not good enough.

So, I tried a Y adapter off the aux ch with a reverser on one leg but the reverser caused the servo to chatter endlessly.

Finally, I went with plan C and modified the servo connections internally. I was pleasantly surprised the servo still worked when I got it back together.

I haven't yet finished my FunCub. I'm going to modify the tailwheel connection to the rudder horn and am applying decals while waiting for some small charging adapters to arrive. I'm looking forward to flying it but am apprehensive. My experience is with a Hobby Zone Champ and Phoenix 4 flight sim.

donies,

I learned to fly with a HobbyZone Mini Super Cub & RealFlight. I don't think that the FunCub is any more difficult to fly (you have more control). If you're fairly comfortable with an aileron trainer on the sim, your probably ready for the FunCub. I have no idea if you have any help or not but if at all possible get some assistance for the first few flights and you'll be fine!

Good luck and enjoy!

Robin,

Thanks for the encouraging comment. I just purchased Real Flight and hope to get started with it this weekend.

donies,

It's not a replacement for an instructor but if you don't have access to one it will go a long way in preparing you to fly on your own. The sim gives you the opportunity to fly, learn, & crash without the expense of risking a model until you get to the point where the stick movements become second nature (and believe me they will)! I'd recommend something like the Nexstar with ailerons as a trainer as a good choice to prepare you for the FunCub.

I still recommend having some help for your FunCub's maiden flight as any number of things can happen on a first flight that are best handled by someone with some experience! It can be a total non event or get real exciting real quick (don't ask me how I know)!
