Hi ,

I have just got a Chip DV, 4 aileron biplane, anyways , what wat do you recommend setting the radio up to allow me have the flap option as well?? i have asked twice on DV thread but no replys, in the DV manual it says use 2 x Y -Leads which allows use of flap option, that cant be correct,even though I havent tried it I cannot figure out how it would allow me have a flap option and still have use of ailerons.

Any help much appreciated , Thanks

maybe they mean to use a y lead on both the right aileron servo's, and then another on the left servo's

you cant cos a y-lead will reverse one of the servos , both servos need to go the same direction on each side of fuzz, i know two yleads will allow me to work but not with an option of flaps as well

A Y lead won reverse the direction of one of the servo's, just spilts the signal into two wires so 2 servo's can operate of the same channel. I believe you have one servo per aileron per wing. So one top and bottom on both wings. If it does. SO right servo's operate off of channel 6 and the left ones of channel 1, then set this up on the tranny. Just try it will work.

Ok ,you are right but sorry I misrepresented my question, my opinion was the best way to use flaps on a Biplane was to use flaps on top wing only, therefore is ther another way to setup my top ailerons act as flap only???(witout introducing bottom ailerons)


thanks

depends on your tx
you could set up the top ailerons on channel 7 and 8, run the bottom ones using channel 1 and then mix 7 and 8 off of another channel such as 6 to give you flaps and channel 1 to give you your ailerons, that's the only way I think you can do it, will take 4 mixing funxtions though.

Sorry I misinterpreted your question.

Why do you only want to use the top ailerons, is that what the manual says?

Thank u foofydoo ,
that is a good solution,but infortunatley it takes 3-channels and a lotta mixing, the reason i ask is because i have been thought that on a small bipe that flaps(non extruding type) were more effective on top wing only , to reduce wingloading but still have a drag effect.

But i realise ur solution is the only flap option available.


Thanks

Sorry If I missed the question on the DV thread - (too much to read out there :-))

Here is what I wrote with a few notes added later.

Some computer radio priming options:

Four-ailerons -

The Double Vision will fly very well with all four ailerons simply connected with Y-leads and no computer mixing. Although this is possible, it is not recommended, to run all four servos from one channel using three Y-leads. It would be possible to use an expander such as a JR Matchbox and also a separate aileron power supply.

A more desirable load sharing option would be to use two receiver channels and two Y-leads. One for left ailerons and one for the right ailerons especially if you want flaps etc. Most of today’s computer radios offer this option. One channel; being the aileron channel and the other, being a standard or user-selected mix option. (One lead to left and one lead to right side) (JR uses AILERON and AUX-1 for example)

A two-channel double Y-lead installation allows the use of the Flaperon option, (Elevator can be linked to move the ailerons up and down in concert). It also allows the use of the Flap option (A switch or rotary/slider control can be employed to lower or raise the ailerons as a form of flaps.) (With JR it would be the LAND/ELEV switch and the standard options that come with the radio).

The Flaperon option can be used to tighten loops or aid in landings and take-offs. The Flap option allows the pilot to experiment with very slow flight or high angle-of-attack maneuvers such as “Harriers” or “Waterfalls”, etc.

A third option is to use three channels, one for each top wing aileron and a third mixed-channel with a Y-lead for the bottom two ailerons. This method spreads the load over more channels and keeps the bottom two controls as pure ailerons, while allowing Flaperon and Flap mix options on the top wing.

A bi-plane with the top ailerons deployed as down flaps will fly very slowly and allow steep descents into small landing sites, The bottom two ailerons keep on providing a lot of roll control while the top two, even thouogh they move, are basically only functioning as flaps.

Four channels can be used to give a wide range of mixing options. It is suggested that no matter what mix combinations experiments you try, that you always have a condition that you can return to normal aileron flight operation. Also, although the Double Vision is a relatively forgiving airplane, these experiments should be performed with a good height safety margin. (This would use the standard mixes for two of teh ailerons, Say teh top ones, and then mix aileron with #3 and #4.

Then mix Flap with #3 and #4. This would take four free-mixes. Then you can have

4 ailerons - for hoigh roll rates

Bottom two only as ailerons

Top two as flaps

All four as flaps or, dare I suggest it CROW-----Ailerons in or ailerons out - - top ailerons dowm and bottom alierons up or vice versa.

All four as flaperons.

A few spicier options woul dbe to drop, or crow or raise only one or two ailerons on onse side I hvae seen some wild and vertically climbing flat spins around the dragging wing....



In all cases, remember to program the computer radio to include trim on all four ailerons.

Please note that the above are only suggestions that you might like to try to add more fun to flying the Double Vision.
