Been seeing outerzone.co.uk a bit nowadays

Also wanted a low winger aerobatic mid-size to practice some mischief with before busting my lovely Multiplex Tucan.

So adapted the Pilot Attacker 28 to corro.

The OK Model Co. of Japan which produced the Pilot kits and accessories was a world leader in it's time. I got 2 kits in 1985, a Piper Cub 20 and a QB 40 (QB for Quick Build.) I also built 2 QB 20s shoulder wingers from kits made by the late Clarence Pinto of National Models, Bombay. The Pilot kits were extraordinary; at a time when lasers were only seen on Star Trek they produced die-cut kits of extraordinary precision, that literally just slotted together!

I downloaded the plans for the Attacker 28, and adapted them to Corro. Changed the name from Attacker to Zattack, as the Boss said, Make In India! 

Sir Subscribed.

with front row seats booked. 

Colonel Saheb 

Plans printed - printed for the Birdie 10 too - will make that as a balsa scratch built sometime 

Fuse and Tail Feathers cut, wing built

On the field

Let's see who can identify correctly where the cockpit canopy came from 

Nice build.
Well you bought a new mouse I guess. Nice juggad for the canopy.

Maiden (this morning) was uneventful. Needed some downtrim, and reduced aileron EPA on low rates from 50% to 37%, giving about +/- 8-10 mm throws. Expo set at -40% to calm those maiden nerves, but will now make it 25% - should be crisply responsive

Video was a flop show   . For some reason (probably wrong button pressed by the cameraman) there was no video  

Will try to take another tomorrow

Nitesh is right on!! He is the "Mouse of the Year!" 

I got the mouse 3 months ago, and was saving the packing 

Span - 53", AUW with 2800 mAh 3S is 1.3 Kg. Plans said 1.6 Kg 

Getting 7 + minutes flying time, using a 3536-1250 KV with a MAS 10*7 prop. Used a 40/50 A HK ESC, motor maxes out at 43 A 560 W.

Sorry, the link for the plans

Yet another beautiful models sir.  
Sir app itne models rakhte kaho hoooo ?  

"Mouse of the year" let it be "troublemaker of the year".

Quick and nice build Sanjay sir    Thanks for the  website   i was looking for 3D Plane Balsa Plans and i got "Extra 300" balsa plan here http://www.outerzone.co.uk/plan_details.asp?ID=3606

Great build sir....  Hats off

Thanks Nithin, Manoj, Doc 

Actually it was a longish build by Spad standards. To adapt from a balsa plan to Corro is difficult - you have to measure dimensions, draw extension lines and measure angles, figure out where to reinforce.......

Flies well though, so it's all worth it

Manoj, earlier I used to crash a lot, and I was building lots of high wing trainers.

Now I don't crash so much, and am enjoying flying low wing aerobatic models. So I have a whole bunch of High Wingers.....which will soon suffer from Hangar Rash

(Watch the For Sale space )

great build sir   {:)}really inspiring

rohan

Thank you Rohan. Where do you fly in Delhi?

Awesome Plane sir ..
Nice Colour scheme..
Will miss flying field tomorrow ..
Last time i visited field was an excellent experience with You , Girish sir and Fun Cub ..

eagerly waiting for one 

Thanks Aditya, will miss you

If these planes being good at Expressing themselves like you , they will definitely refuse to go from such an awesome space in your Hangar . May be some already learnt expressing themselves .  
Fun Cub , What's in you mind?  

sir i havent flown any of my models yet i have a quad under progress but i have flown 2-3 planes in dwarka and the janakpuri district park, but i am looking for another place to fly coz its dangerous , people might get hurt so if you know any empty ground do tell me...
regards
rohan

Build log came out in the same speed as the name sounds. Zatt...ttak.

One more beautiful creation Sir. 

should've been named jakaass !!

What a design...what a make ..surely my next one

Awesome model sirjee...
WHy always same colour scheme?? try new colours sir, be creative...

One query... Why so you use wooden reinforcement instead of coro

Please donate some of your superb models...

We fly in Gurgaon, Sector 29 Leisure Valley Park Sat & Sun from 6:15 am to about 8-8:30. You are welcome to join

Thank you Colonel Saheb. My builds are not that fast. This took about 5 days @ 3-4 hours per day

Gusty sir 

As long as it's not "Jackass" 

Thanks iwincar

1. Thank you 
2. How many of my models have you seen to comment on the colour schemes and my lack of creativity?
3. Wooden reinforcement - you are intelligent enough to answer that yourself
4. I have donated over 7 models in the last 1 year. And am now giving more free with some other products

Missing pics

I'll be happy to join you sir, as my exams are ending i'll be making planes for a few months but i'll try to come as gurgaon is a bit far from my house...
Regards
Rohan

which metal u used to make your rc plane ?

The Big Nasty 3D plane you built had a similar wing...
The Corrowot had a similar fuse and wings were white like this but you changed it later...
The avispad also has blue fuse with white wings...

I was asking that using wooden reinforcements increases weight doesn't it?
 
Another question....
What thickness coro has been used on the tail?
 what have you used to reinforce it?

Not metal. I used corrugated plastic sheets, called SunPack locally

Colour is a function of available corro
Aeromodel building is always a judicious trade-off between strength and weight
4 mm on tail, no reinforcement

Thanks sir...

Topalle, Colours - a function of available corro. Let's see yours?

My models all siezed... The electronics taken away by my parents...
;(
Just a matter of 6-7 months... I just managed to log a ~20 hours on the simulator
I'll be back after all entrance exams are over...

Yet another model by Sanjay sir. but this time the looks are much better than a balsa one.
If the side flute ends and wing tips are covered anyone could mistake this plane as balsa without a close examination.
amazing build  sir..

Ashok.P

 

Do your parents know you have spent 14 days, 57 minutes so far on this forum  > >

Thank you Ashok

Coincidentally, ive been watching outerzone.co.uk for a last few days after seeing a jr falcon fro a fellow modeller. and another trainer model and planning to adapt them in Corro.

Ashok.P

Ashok, make the Spad Cap

Excellent model. Mine is going strong, not flying it currently as I need some more Lpos - 2700-3000 mAh. I have only 2, and am using them on the Zattack.

That model is superfast and awesome to be captured in a frame, and you blame the drunk cameraman, unfair

Great model from a superb builder.

That was really some good photography! I don't blame the drunk cameraman, the problem is when you are sober 

Sanjayrai55 how do you fix wing On red coro stick? In extreme top photo
It is without rubber bands.
You have used screws to fix wings pl explain method

On most of my models I use Bolt Down systems.

See the build log

See Reply # 4 onward

http://www.rcindia.org/electric-planes/spadstick-electric-(full-size)/

See this picture:




The holes drilled and M4 Blind Nuts fitted. Wing bolts (Nylon, M4) fit into them

Finally. Video was taken on Sunday (yesterday) and originally is 1.3 GB 

Really strong cross-wind, but the model took it reasonably well

Awesome sir!

superb sir

sirji as usual the model is wonder the full.....but cameraman need training... to use zoom and focus....

& he mentions camera is not good!!!!

I mean with such models we should be seeing Hobby king style flight review etc.



Ps - Sorry if i have hurt the cameraman's feelings.

The cameraman is strictly amateur - my younger son. Congratulations, you have just been appointed official cameraman of Boltz

PS: The ex-cameraman wants to meet you in person

Very nice Sir 

  guys   

sir, you're oozing builds, emitting builds, radiating builds now, 

Thanks GS

Jebelsky wing anyone?

Er, Jebelsky, sir?

Apologies, bade saheb 

JEDELSKY!!

Any experience on these wing designs? Will be a first for me, although when I was in school (i was, you know  ) I made a Mercury Marauder (I think) a sailplane with an undercambered wing. Covering was ...... with tissue and dope! Had to glue the tissue to the ribs for the wing underside 

Returning to Zattack, I cannot praise the designer enough.

Without electronics, but with Landing Gear the cost is under Rs. 400.

Any 300+ Watt motor will work fine.

With low rates it makes a great aerobatic trainer, capable of all FAA Aerobatic sequences, and at high it is Hot! Real Hot! 

very good sanjay sir bravo 

  Gaurang

Sir ji ,
which glue u use for coro ( plastic cardboard ). I use quick fix but it doesn't work.

Cyano, SR 998 (from Fevicol) and Hot Glue

http://www.rcindia.org/electric-planes/(yet-another)-avispad/msg155045/#msg155045 for SR 998

Can use Cyano with the same preparation

For 90 degree joints (butt joints) with less surface area for gluing, use Hot Glue. But careful - adds weight, especially in the tail section

Thanks sir ji it helps me a lot.

Wow Sanj, you have churned out another superb looking plane this "Zattack" in 4 to 5 days.... amazing!!

The decals and colour scheme is lovely... it looks a proper kit built plane. But then again all your models have some super stripes and decals which I admire... (Pleased to hear Spad cap is being saved in the hanger ....... still reserved I hope!!).

After nearly 10 months I completed the Depron one metre span model D & A. I started it last year and will be maidening it soon if weather permits, was being distracted by this Mako which I have managed to build 2 of now, both extreme pleasure in flying and no problem at all in landing in tall grass or muddy field.

Winter is here and am thinking a coro plane would be a good project.. Lets see!!

BTW, please do upload some measurements for that stand... need to build one for this D & A....

Have fun and safe landings with Zattack!

Hi Dee. Good luck with that Corro model. Also looking forward to reading more about the 1 m span D&A

Hi Sanj,   D & A is completed and flying quite well now after moving the C& G a lot forward and adding quite a bit of lead in the nose. Very responsive and quite a fast plane.... trying to learn side slipping on it... Rudder seems to drop the plane quite a bit so need to sort that out. It happens with my Mako too, on straight flights rudder can be compensated with elevator but when trying any manoeuvres it just drops out of the sky like a brick!

Did I read Zattack is in hanger for repairs somewhere on the forum..... That is sad, how bad is the damage and when is it out flying again?

Deepak, the Zattack is fixed and flying again; as good as ever

Good to know... Enjoy it Sanj....  ( Spare the Spad Cap 232 for me)

It burnt!

A tip stall, extra hard landing hitting a wingtip, and the battery caught fire. Dense smoke, flames, big crowd collected until I told them it's going to explode

Have some photos, will upload soon

Oh no... that is sad... which one Zattack or Spadcap.

Touch wood I have crash landed my Mako and other electrics so many times and have found Lipo at intact in the bay... it must be the foam that has been protecting it. A lesson for us all to adde some extra foam in the battery bay.

This was




This is

Deepak: There was foam - the foam burnt fast and furious 

sir, wings are still safe to some extend and model looks repairable

Anand - already thrown
