Originally designed as a Balsa Model for 25 size engines, this has been adapted to corro.
Plans are on Outerzone.co.uk
Brief Specs: Fuselage - 990 mm 39"

For anyone making this, I would recommend narrowing the fuse front by 1''. It's too wide - guess it was originally supplied with a cowling, with dual air intakes so the width was to accommodate that

I will be using the following power plant:
Motor : 3536-1400 NTM

I make the supports as in the picture above, and trial fit the wing with rubber bands. Then drill through, and remove the wing; fit blind nuts into the support plates

Habituated as you are ... An excellent model once again... All the best for the maiden sir
Thanks Doc :thumbsup:
Nice model sir .. :thumbsup:
Waiting for maiden..
How did you get the glossy finish sir?
I mean the finish of the black area.
Thank you Aditya

If you read the post.....I use Vinyl Trim
Sir,
Besides the quality of professional workmanship and the quality of the accesories used, it is the small details that blow me away.
This time it is the rivets on the windscreen...
:hatsoff:
Thank you Iyer sir
Believe me when I say my total spend (without electronics & Landing Gear) on a model like this is less than 600 Rs.
After crashing I recycle the parts ;D
Rivets, glad you noticed them. I didn't :rofl: Unless you meant the 6 mm long Self Tapping Screws holding the windscreen (which is cut out from an Indigo Air drinking water glass ;) ) to the 6 mm balsa base plate, which is black because I covered with coloured tape
Someone PMd me as to how I got full size plans
1. Why PM? Put it on the forum; someone else too might have the same query
2. If you read some of my earlier posts this has been answered before
3. Go to a big photocopy shop - the type who have A0 A1 printer/plotters, normally do Engineering/Architectural drawings. The rate in my place is Rs. 80.
4. Please don't ask where I got the plans. Take your plan in a pen-drive in a .pdf format and ensure printing at 100% size
Sanjay sir... Thank u for ur words... I won't do pm here after...
Hey Dev, you are always welcome! Jut ensure Personal Messages are of a personal nature ;D ;D
Once more a beautiful model sir.
Awesome work sir.
Awesome Sanjay sir :) Beautifully done!
Sanjay sir excellent build {:)}
Sir how to make cuttings in formers I want to know whether it is with jigsaw motor driven or hand driven

Once more a beautiful model sir.
Thank you Colonel! Now come and fly it while it is still fresh :giggle:
:thanks: Vishal. Now if only I had your flying skills....
Beautiful model as usual
Thank you Prashant
To cut the inside holes/rectangular openings in the formers, I first drill holes in the corners of the opening to be cut. Then either I use a coping saw, or small circular saws on a Dremel or flexible shaft grinder. Finish off with a file
(http://s25.postimg.org/5l4jm7osf/IMG_20150612_162911.jpg)
Thank you Ashok-ji. Now that the sweepstakes are here, I am really looking forward to your builds, to see how a master does it! :salute:
WOWWW.... as usual what a superb build... in await for the maiden videos... can we share these pics on our facebook page?
regards
Sujju
Thanks Sujju. I'm honoured
Sir your patience while working on a model is great {:)}
Also landing gear for models are readymade or made from aluminium
Both - readymade and aluminum (an Alloy) :D :D
See this - http://www.rcbazaar.com/product.aspx?productid=1177
Available also at RCD & HK
Good till 1.6~ 1.7 Kg models (25 size)
Ugghhhh!! The worst build I've ever seen (being sarcastic)
What to do, you have blowed up my mind leaving only such words.
Thanks Nitesh (I think ??? ??? :o :o)
Last pics before maiden

Where is Calvin?
I used a Balsa spar :D :D :D
No maiden possible today - Gale force winds :o
Beautiful Build as usual sir. Waiting for Maiden.
Personally, I feel the thick fuse looks very good.
superb build sir I love the colour scheme {:)}
Maahin, thanks! But you said the fuse had to go on a diet........ :giggle: :giggle:
Thanks Jana :thanks:
Sir, Excellent built. But I am not able to see PICs......( I have seen it on the BOLTZ Whatsapp)
May be its office LAN or some security thing, request you to put pics the normal way on RCI.
In case you want to put High quality images you put both so that everyone is able to see your fabulous builtz.
regds
Saurabh
No
Lovely plane Sir :salute: :salute: :salute:
Always make nice and Attractive Look Model.
Taitil-bhai, thanks :thanks:
Haven't seen very much of you on RCI. Hope to see more builds from you :D
:thumbsup:
I find wide fuses great because of the large volume that one gets inside. They do add to the drag, but if the front of the fuse is adequately tapered, I believe the drag/air block can be smartly tackled with.
Look forward to the maiden.
I was busy in work Sanjaybhai. I also want to make model for this sweepstake. And i will Try.
Good luck, all the best :thumbsup:
Finally, the video
Expert Test Pilot Girish Sarwal at the controls :thumbsup:

As usual chief, Awefffssum build
Very nice plane. Flies very stable
Awesome build & great flying :salute: {:)}
Another super build Sanj.... The build quality has got better too what super decals and finish..Too Good!
Thanks Dee
Really amazing especially the video.
Sanj compared to MPX Acromaster, how different is this in specs and characteristics?
Also now that you have perfected the build and planes, which model flies the best in your opinion... I mean which model flies best at slow speed but is good in aerobatics at fast speed too..... Which one is the most stable model out the ones built so far?
You recommended Spad Cap 232 ..I have got that on the build should be read soon... Is coming to around 1,6KG without Lipos... Lets see how it flies??
Need to build one of these two next; .......Chris Foss Acro Wot or MPX Acromaster! Any idea where I can get some plans?
Dee this has no link whatsoever with the MPX Acro. That is a 3D, and this was created in the 1970s when 3D had not yet entered aeromodelling
A model with very good slow flying characteristics - and good aerobatics at high speed? Most of the corro ones I've built have met their demise through the dreaded tip stall at low speed, mostly on the landing approach. So no, have not really come across something like the MPX FunCub
1.6 kg - something is wrong Dee! Mine was 1.1 Kg without LiPo.
I will weigh the wing and fuselage separately and upload... Ended up fitting metal gear 17gram servos throughout. The lipo hatch is 6mm Depron (2 sheets of 3mm with scrim tape in between) on the fus with hot glue instead of chart paper... Also needs some nose weight as the balance point is not as desired...
Was just reminiscing the very sad end of this model. No, it didn't crash. Was unsighted, and went off the field onto the road.
Never found it

Very good build rai sir and good flight :thumbsup: :thumbsup: :goodjob:
nice {:)}
Thank you Gaurang and Bunty
(It's one year old though ;) )
Sanj,
My Spadcap met the same fate...Its lying in the Rapefield crop somewhere. I left my number with the farmer but he never called so either it was chewed up by the combine harvester or he has passed it on to someone.. ahh never mind..
However my Akromaster is coming up very nicely, will post some more images on the blog soon..
:thumbsup: :thumbsup:
All the best, and waiting for it :D
Nearly completed the Akromaster today.. Will post the blog on a new thread.. Sanj you have probably made 10 models in the time it has taken me and Allan to make this one. :) But we have had fun and its been very enjoyable.. Thanks for your inspiration. All we have to do now is fly it... :)
Congratulations Deepak! Looks superb {:)} {:)} {:)}
Especially love the little curves on the wing and tail feather's tips :thumbsup: :thumbsup:
Beautiful model sir.
me to like those curves.
Thank you Sanj and Manoj... Had a lovely day yesterday flying other planes, would have been good if we could have test flown the Akro but Allan had to make slight alterations to it and he could not complete the same and bring it to the field.. Maybe next time..
