Not including shaklets due to difficulty of construction...
Took inspiration from many build logs at RCG
They all were in depron...
I have never worked with depron till now, so I built it with coro

The dihedral brace is coming out... any sugesstions for a better one?
Title: Re: Airbus A320 under construction
Post by: prateek13 on November 12, 2013, 11:43:00 PM
Make one using 1/2 inch wood dowels, I used the same for my Glidiator's wings.

Post by: topalle on November 13, 2013, 06:47:22 AM
I tried using the beading strips but the glue doesn't stick satisfactorily ( or I don't clamp properly...)
I nailed one to another but? He next moment there is a crack on one of the strips...

You should spend some time reading the posts on this forum before asking
Title: Re: Airbus A320 under construction
Post by: topalle on November 17, 2013, 03:26:09 PM
Improvised the wing... dihedral brace is strong now... used araldite..
The problem was improper clamping and lack of patience..Now I made the fuse skeleton but I am unhappy with it...

Can I use pvc gutterpipe ( round big pipe) for the fuse...it will be heavier but more crash resistant
Any comments on this?...
It will also be a new spad model

Trailing edge needs to be stuck at ends
The control surfaces are added
Title: Re: Airbus A320 under construction
Post by: topalle on November 19, 2013, 09:09:54 PM
Control surfaces... flaps and ailerons

The 35" fuse pipe section alone weighs 1 kg... should I use it? I will try to get some lighter pipe of the same size
Title: Re: Airbus A320 under construction
Post by: madaquif on November 19, 2013, 09:34:12 PM
this just a suggestion.....

has any one tried using 2 pepsi or coke pet bottles???  ..    the 1.5 or 2 liter one

should be much lighter in weight...and somewhat crashpoof

Title: Re: Airbus A320 under construction
Post by: topalle on November 19, 2013, 09:46:21 PM
Oh... what an idea... thanks... but do you know how to join two bottles?
Title: Re: Airbus A320 under construction
Post by: madaquif on November 20, 2013, 02:43:51 AM
Cut the bottom of both the bottles...make a notch on one of the bottles...

then join both the bottoms of the bottles...

use any industrial grade glue Araldite ..... thn wrap it with a fiber tape....;)  just for strength

u can try hot glue but i dont think its gonna be as strong ..

do post some pics if it works...

cheers

Due to issues in construction of fuse... I have decided to build a rather boxy fuse than a fancy round fuse...
After this flies well I will definitely remove this boxy one and try to get some depron to make a round one...

Ambitious project. Don't bother about the comments/feedback. Just keep at it. All the best!

What is the fuse made out of?
Title: Re: Airbus A320 under construction
Post by: topalle on December 07, 2013, 01:20:28 PM
Didn't make the fuse...
Its a pvc gutterpipe...
I will wrap coro around it and remove the pipe afterwards...

Restarted the work... left the wing in a dilapidated condition...
now renovating the wing.. boxy fuselage to be done soon...
I used very thin control surfaces and thy were not even placed properly... removed them and i am going to add new ones... should scale sizing of control surfaces do?

Great bro. Just a suggestion. Try contacting shantanu borate sir from mumbai here. Few days back he build a similar model using round thermocol tube. You can ask him where he got that. I remember he told me once he got it from a gift shop.
