So i have started building a new foamy 3 days back and have just completed the fuselage. Members kindly put forward your suggestions and reviews. Thanks.
Here are the pics:

Will now move on to the wings. But before that, now i really need inputs from all members.
My 1st question : How do you cover the model(plz briefly describe the process and the materials required) after sanding to cover the minute pores which are formed?
My 2nd question : How do i effectively cut out the block of foam at the center of the fuselage so that i may put in the electronics? Thanks for your time and patience.

Hey that looks great. Did you fuse multiple sheets of depron and sanded it? that causes too much wastage right?
Where are you planning to put the electronics? Will you have a grove to place electronics?

rohitgupta322

Thanks ashok bhaiya. No, i didnot fuse multiple sheets. I had this 100mm thick block of biofoam, i just cut the shape with the help of a hotwire and then sanded it to get those rounded edges.
Yes, placing the electronics is my next task ahead for which i need help. I certainly need to groove out a chunk of the foam to get the electronics in for which i need suggestions on how to do it effectively.

HI Rohit, great job with the hotwire and the smooth sanding. The structure sure looks good :)

rohitgupta322

Whoa! Welcome back Ritesh bhaiya and thank you so much for the compliment.

Anyone with the answers to the questions!!!

1) You can use  colored packaging tape(wondertape). This is the best in my opinion as it gives both glossy looks and great strength to your model. You can also use paint- any water based paint, fabric paint, but it doesnt add any strength just looks!
2) Are you planning the fuselage compartments like easy star? You can cut  it in half by hotwire. I think you can make compartments by heating a block of wood of same size and pressing it hard.( Just try this on some scrap and practice. I havent tried this )

fantastic job!
such a nice design and finishing...............
you can use vinyl sheet for the covering. these are having strength and nice for decoration of rc models.
you will get it from Dalhousie square in Kolkata.
let's make and fly!

its really nice job!!!! great finish like pro....

putting electronics will be little tricky in there!!!!!
u may cut out some bottom and put ur electronics in there.....

or say cut it into half vertically make some compartment for electronics and motor as well...but i think u must not be willing to do this as it looks so nice...

i think more experience people on this forum can help u better!!!!

Thanks so so much for the encouragement.
Yes, i did cut the fuse vertically into two separate parts and took out the chunks where i plan to put the electronics and then glued the two parts back. It looks the same as outside and also has the much needed space for the electronics to be put into.

ohhh so u already did that grt!!!
try to make some hatch or say opening from where u can have access to electronics....
may be from top, where u will attach ur main wing would be perfect place for this!!!! of course if the wing is removable!!!!

cheerssssss

Yes thanks again for the valuable suggestions.
I ll just leave the top part of the space for the electronics open. During the flight, ill put the wing over it and tie it down with rubber bands. Will that work?

rohitgupta322

I just wonder, won't the vinyl sheets be too heavy if i cover the entire fuse with it? If so, is their another replacement?
Be Inquisitive

avishekghosh07

Vinyl sheets are not heavy.it's just like stickers. you have to peel it. We generally use vinyl for foamy as well as balsa models bcoz of reflective and glossy.

You could try with color tape or thin color film for covering.

Sethji,
Happy to see your post. Long back. but your homepage perhaps a little bit bulky as always it opens up slowly with slow response (while Scrolling) even in my 2MBPS broadband connection (Downloading speed more than 400 kbps, uploading speed >144 kbps). Please be with us. Now we have plenty of materials. Styrofoam, High dencity thermocol, Coro, CA Glue, Electronics in Kolkata. Of course, those are not sold for modeling but other purposes.

Rohit, why shrink-ed into Sofa or relaxing after long sanding ? Cut with hot knife or bended 1A bend hot wire cutter for making space of  Electronics. But the space of pushrod, you have to cut in two pieces. What is the current weight of fuselage ? please dont throw the large waste blocks. They can be used for free flight gliders.

Take the 40V/5A Power supply from my office. It's in the office and cut the fuselage. You can take in absence of me also just informing in office.

What about the wing ?Thinking of using Coro or same foam ?

Thanks.
We have to unite and to prove ourself to make indigenous products as well as marketing / Canvasing them. I'm sure we must achieve success if we try unitedly.

rohitgupta322

Well, thanks kalyan da. BTW i was watching TV sitting on the sofa with my fuse on my lap after having already sanded it. My sister decided that it was the perfect pose for a photograph and so there you have it.

Well, Sethji's homepage loads quite quickly in my computer without any problem.

Why dont you use the same technique as half cut fusulage with compartments inside and detachable wings?

rohitgupta322

I didn't understand your question Ashok bhaiya?

Check out some of the Easy Star pics and its fuselage. I said you can mimic the same idea for fusulage.

rohitgupta322

Oh ok thanks.
I got confused since there wasn't any pictures attached with your post, so i was wondering which technique you were talking about?

hi,
long back i was doing practice to open a slot in a dense thermocol block like you have. seen a video in youtube and finally i was able to dig a slot in the block.
see the pic below and try to understand the illustration and text.
