The best bang for the buck is the UScomposites 635 thin resin system. It runs around $65us per gallon. It has a 20minute pot life, but i have used small batches of it for as long as 30 mintes.

I've been doing large scale edf builds in this forum for years. I'm subscribbed and following.

Don't take it personal. People don't post in build threads like they used to, but it doesn't mean no one is interested in seeing your progress.

Post, to show interest.

Keep posting pics, great subject!!

Thanks guys for encouragement and online support, i had to get stuff for the next step of this and Constellation builds, so now that i'm almost ready to go, i will start working on it tonite or tomorrow by making couple of ribs and spars still needed, then with use of 2x4 to straighten out the root ribs by clamping them on and using 90 degree triangles to get all angles perfectly right. This way when i will place both wings together on each side of the 2x4, both wings will be exactly same. This is very important and will be crucial step of this build to get the wing right on the money, otherwise there could be aerodynamic problems when this model will fly.

After getting all the angles square and perfectly right, certain spars and rib sections will then get copulated with 5.8oz carbon fibre cloth before i will glue structures together. Since its not possible to split wings into 2 pieces as inboard and outboard sections due to anhedrial curve post engine nacelles, i have decided to make wings plug on the sides of the fuselage by use of 3 wing tubes at load baring points!. I might split the forward wing from centre and rear portions so transportation and storage will be easier to do. If i did that, then forward wings will become part of the fuselage as permanent section.

I looked into getting this or similar version of it here, comp store has System 3 stuff but just to get a pint kit is $60 plus taxes!!, so i will try my Z-Poxy and see how it does as System 3 resin is just too expansive to get in such small quantity... I don't need a gallon of it either, so lets see...

I think its great what you are doing ... be great with a couple of turbines in it a one in the middle .. Ive built extensively from plan, your plans look enlarged?

Scott.

You have to look at the number of "views" your thread is getting to see the level of interest. Lots of guys like to see interesting projects but won't necessarily comment or ask questions unless they are contemplating a similar project...

I didnt say System 3 epoxy, i said USComposites. The pricing was just to show how cheap it is, it is available in smaller quantities as well

Thomas,

I asked them for USComposites 635 thin resin and they said, that brand is not available in Canada so they suggested System 3 as similar alternative to ur brand. Well how a pint kit of System 3 is cheaper then ur resin when u get gallon for 65 and i'm getting just a pint kit for 60 Cdn....If you have some to spare, let me know, lets see if we can work something out ourselves...

Yes would be sweet with turbines but only if i could afford them, which i can't, so EDF is my way to go about it for 2/3rd the cost or even less....Once i start making short kits, it will be great to see somebody to buy it and covert it into turbine version to see the difference.

First off, going through Most "distributors" for composite materials is going to cost you ALLOT of money. I have done allot of research on where to get composite stuff for the cheapest amount without sacrificing quality. US composites is by far the best "bang for the buck" when it comes to epoxy. If you buy a gallon of resin, it Includes the hardener as well. So you are actually getting 1 1/3 gallons of mixed epoxy..

Call them and order it direct from them... (you'll need the medium resin). $75/gallon, $42 1/2 gallon, $24/quart

Awesome. You have skill! Following with interest.

TP.

Alright Thomas, i'll contact them directly and see what i can get from them. Thanks buddy...

Strob777, thanks a lot for complimenting and appreciating my skills in making this beautiful replica of "Queen of the skies"...

I have spoken to couple of custom electric landing gear manufacturers to make all 4 gears for this model, i have provided them with most of the needed information and documentation, now i await there reply with price quotes. I will be adding ply reinforcement plates and carbon to reinforce landing gear bays structures in the wing frames. From the sounds, it looks like main landing gears will have scale 3 point mounts, very similar to actual aircraft's configuration.

Hey Props,

Nice thread. Your subject, is in my opinion, the hottest looking aircraft ever to grace the sky. And not a gun or missile to detract from those gorgeous lines.

I will follow closely.

Roger

It's great to see how much interest is really there in this project. Thanks for chimeing in Roger.



I like to know if a Robo straight strut's main tube leg's length could be extended from max available length of 9-13/16" by adding another 1-1/4" to it. If yes how can this be done and if not, then why?.

The reason why I'm considering this route, is the company who is going to make landing gears for this model dose not want to add side links and drag links to the main nose leg due to higher costs on my end. All they can do is traditional straight leg on electric retract and i'll have add side links and drag links later on myself. To do traditional type both mains with trucks and nose gear they want $1000 USD, now considering that if nose gear leg will be traditional type from them, why have them do it if this option could be done by adding extension myself, this way i can save on cost yet get landing gears done.....

Had to get another table so i could work on both wings together. Both wings were placed on the tables once both tables were set up for this
step. I also got 2x3x96" stud to align both wings. Basically both wings were set on each side of this stud, leading edge strips were loosen up, this allowed spars to move easily, then both root ribs were clamped on the stud, this straighten the ribs against it, then opened up my drawings and started to measure each spar's tip for it's ground clearance, this way i start to match all the ribs that were bit off by taking out that particular spar and cutting the root joint on better angle so tips would measure the same as on the drawing. Took few hours to do this as there were few that needed this attention. After this, i made sure all the spars were 90 degree to the root rib and then did same with ribs to the spar joint angles. I still haven't glued anything as yet, i will go over again to make sure all are perfect before i glue these the joints together.

Another area of concern is where main landing gears will mount, now do you guys suggest to add lite ply strengtheners on both front and back spars and then both rib or should i use triangle gussets on each inner corner, and then do 6.0oz carbon cloth's lay up on the inside of these boxes....

i suggest steelstud

why do you complain about me?

looking good

Eric, go away man, this is rcunivese and there is just NO WAY that you could only possibly like my builds on here and no one else!!, you definitely have some agenda against me hence why you have been chasing me through out this site!. I will keep reporting unless you BACK OFF from my threads and start sharing ur knowledge and building experiences with other guys too. We haven't seen a single build from you in ages, if you know so much then lets see what you can build and if you simply can't, then juss go away man!....

Here are pictures of the wing structure where main landing gears will mount. In first picture, from the centre, 3rd outer rectangular torsion boxes will become main landing gear bays.. Both main LGs will be mounted very close to the nacelles, just behind main intakes on the inner sides of the nacelles. 2nd picture is showing Right wing's gear box, 3rd picture is showing left wing's gear box

Should i make stiffener plates of both ribs and spars n glue them on inner side to reinforce these bays or should i just do 6oz Carbon cloth's layup on present structure and that should be good enough...

Props4ever, when you make your landing gear check which length you want. The Main gear has a shorting mechanism that shortens the gear as it comes up. If you make it the extended length it wont go in the wheel well.

I may be interested in building a Concorde but I am interesting your building techniques. I appreciate that you share them.
