Sahilkit gave me my V Tail mixers and has been absent from this forum for quite some time now. He is brilliant. I will try and arrange it for you, but you could try Rcforall, they sell V Tail mixers, albeit at a higher price.

I know rcforall has them, but shipping them to Kuwait will be a headache for both!

BMP is an extremely inefficient image format.  Please use something like MS-Paint (which comes in any Windows install) to convert it to a JPG, and then upload.

Got it! thanks Prateek, That is a "Y" wire setup which I am aware and have access to, I suppose this setup will make both servos move in the same direction?
So I probably will have to place the servos with its horns parallel to the ground right?
I mean if this is an option then why the V tail??

Admin bhai! shed some light please!

Hey Dorwin! I can't believe I missed out on such a awesome build!!! I've been busy working :( Its come out really good! And considering its you building it, the end product is guaranteed to be beautiful!!  :bow: Oh and I don't think you'll have any problem with the Tx-Rx as long as they are running the same frequency crystals.. And the Y-connector aileron method is a tried and tested one so don't worry :) (I'll be using the same method on my trainer using 2 x HXT900s).. Best of luck with the build man!!  :thumbsup:

Hey Aneesh! there you are...and I was wondering where you disappeared..work eh? the health of Mandur people is in good hands, so no worries buddy.
Thank you for the prediction on the build, yes! it is coming out nicely.
Some sanding still balance on the tail side, and as VC said the canopy still has to be sanded to get the tear drop shape..
So, that's that..how were you and how is your trainer? painted it or still deciding?

Btw, the fields adjoining the Taliegao to St. Cruz road, is a good place for flying after the rains give up innit??

:) yea, those fields are pretty good.. Just passed through that area today.. Also these fields on the way to Aldona are pretty good.. Huge open fields.. My trainer is getting landing gear first, then paint.. When are you gonna be done with the sanding?

Ah! yes, the Porvorim Mapusa highway, awesome fields there..
We shall try there when I come down!
I will try and finish the sanding latest by tomorrow, if I have the time as Thursday and Friday is "Fiancees' day out"  :giggle:
I wanted to ask you one thing, about your AUW, How much was your AUW and what setup did you choose?
Let me know too because my Mustang's AUW is around 250gms, the wing stiffening is still balance, but I don't think that the kebab skewers would be weighing much..
If I can get the electronic setup here, then its not far from completion and painting, if not then again like the Predator, packed and ready for, you know when.. :giggle: :giggle:

Lastly, I don't know what to say, I was idle for like 2 hours(forecasted idleness) so I made myself 5 control horns :thumbsup:
will make the linkages as soon as I get some Ideas...

guys please don't laugh, its not that I don't want to buy these little things, they are just hard to find these here :bow:

Cool! You could start selling those control horn thingies there! ;D My setup is Towerpro 2409 motor on 3 cell 1600mAh LiPo.. My fuselage fully loaded weighs 520gms, didn't weight the wings but should be about 250gms.. So my best guesstimate is about 750gms.. With this power setup it goes vertical a shade under full throttle..

One question! do you have a circuit diagram as how to configure a 4 channel Tx to pair with this bird?
What I mean is can you tell me how to control 2 servos?

For Example: If I move the right stick to the right and the aileron on the right wing
moves upward while the aileron on the left wing moves downward and visversa.

Can this be achieved by using a "Y" servo wire?
Any help will be greatly appreciated!

-Dorwin
If you wanted to control a flying wing or a delta, or if you needed flaperons or stuff, then you would need a mixer, However, If you just want to control the ailerons with two servos instead of one, it can be done without a v-tail mixer. Just cut the leads of the two servos, join them in parallel and connect them to one of the servo leads(cut off previously) and connect it to the receiver. now both will work togather. I assume that you will fix them on each wing. fix them one facing the left and another the right and they will turn in opposite directions. I have done this on my spads and they work fine.

Here is a pic with servo extension attached but it is essentially the same. Hope this helps.

Thanks a lot Edwin,
That answers all my questions, I will do this as soon as I get my servos in some days.

Remember that whether "one control surface goes up and other comes down" depends on how the servo arms are connected to the servos.  They have to be pointing to opposite directions.

If they point to the same direction, they will both move together.

I need some control horns. How much you charging for a bag of 100 pieces? I'm serious! {:)} {:)}

hahaha! thanks VC! I got the message....
If I make a 100 pieces, I will stop going to work and start this as a business;D
These are easy to make, you know those square PVC tubes? used in electrical house wirings?
Well I made them out using a knife edge cutter, a pencil and PVC tube.

Extremely easy to make, just mark, cut the outline and break with a pliers, then you can smooth-en the edges.
fimple!! isn't it ?
