Connect the split flaps of the elevator with a bicycle spoke through the fuselage and just use one servo, it'll be alright. Use Araldit to glue the spoke to the elevator flaps.

didn't get u any pic or diagramm...

You want both flaps of the elevator to work in synchrony, for that you're planning to parallel two servos each connected to one half of the elevator. That's your idea, if I understand correctly.

My idea is, for both halves me the elevator to work together, they have to be connected together. To connect then together, glue a bicycle spoke cut to the end-to-end length of the elevator flaps. Glue it on the hinge side. To glue it on the hinge side, the fuselage is obstructive, so make a small hold through the for the bicycle spoke to pass through and connect both halves of the elevator.

Sorry, I can't post pics. On my phone.

so by that connecting to one side of the elevtor will move both?
can i use .9mm steel wire instead or spoke or push rod??

Use anything that's stiff enough to not bend.

It's looking really good. Great work, Yash

Thank You sir  :bow: :bow: :bow:
Will appreciate any suggestions on the electronic part and more information about CG don't know much about it..  :headscratch:

Take CG @ 1/3rd the Wing Chord from the leading edge.

Re.: electronics, what's the model weight?

A 1000grams thrust motor-prop setup should work.

Cant u tell me more abut cg i have to place cf rod for reinforcement

The CG usually lies at 25-30% from the leading edge.

Installed the main wing servo and engraved the line for CF rod...

Anjan: I disagree with you, For a high winger, 33% is OK. And Yash, in this case, because of the swept back wing, you may have to go 35% +

You might be right, sir ji. ;D

I usually go with 30% behind LE and I build only high wingers. Works well for me.

the engraving parallel to servo wire is final one and i used one cg calculator for that...as my battery will be at the end of the main wing so i think it will counter balance the nose heavy motor....

What's the CG calc estimation? Just curious ;D

30% Vs 33% - what are we discussing here - nano technology? Just fly the damn things and post the videos here - or else, you will end up like me - one dozen virgin models, all waiting to be maidened.

One dozen virgin models :rofl:

Yes VC, only a few more virgins, and Paradise has come to you  :giggle:

hehehe ;p ..i had just asked for information on CG not on 30-33% leading edge..fact is i couldn't understand the concept of cg does it make the plane more stable or make it able to fly?? :)

Problems in my way  :banghead: :banghead:
I have connected the horns of the both seperate elevators but they are moving in opp direction so need some help in that case and also on the landing gear bought reinforced plastic one from rcb how to set up as i know the basic one but is their any specific way???

I didn't quite get you... why don't you put a torque rod between the 2 elevators?
