Length 29inches wingspan 36inches wing loading 8.465 Ounces per Square Foot (approx) Propeller 8x3.8 sf (emp) Motor avionic 1700kv Esc avionic 20 amp Battery wolfpack 900mah 25c 2 cell Servo avionic 9 grm Tx/rx avionic rcb 7x All items are from rcbazaar pune store Wooden spars for support Design material 2mm coro sheet I am introducing my new fully aerobatic trainer anti stress machine Which I build in Coro actually this aircraft I build few months ago but do not install Electronics on it Here now I have powerful motor to fly this model I am showing you some pictures of the construction of this model also I made some modification in the model Title: Re: coro build anti stress machine Post by: wingmanbunty on August 11, 2014, 10:28:21 AM Initial plan done to build airframe
Fuselage construction Title: Re: coro build anti stress machine Post by: wingmanbunty on August 11, 2014, 10:30:24 AM modification in the Fuselage Title: Re: coro build anti stress machine Post by: wingmanbunty on August 11, 2014, 10:34:37 AM construction of landing gear
the prop i am using is 8" it is very large size so i design lending gear in such a way that when the plane take off run still their will be clearance for the prop , so that it do not touch the ground i use wheel of the remote racing car which i bought for my kid and few iron rods Title: Re: coro build anti stress machine Post by: wingmanbunty on August 11, 2014, 10:37:06 AM installation of elecronics
Title: Re: coro build anti stress machine Post by: wingmanbunty on August 11, 2014, 10:40:04 AM i use large size rubber band to attach wings landing gear and prop

Title: Re: coro build anti stress machine Post by: wingmanbunty on August 11, 2014, 10:46:31 AM inverted climb
Title: Re: coro build anti stress machine Post by: wingmanbunty on August 11, 2014, 10:49:23 AM i fly this airplane without landing gear also
Title: Re: coro build anti stress machine Post by: wingmanbunty on August 11, 2014, 10:52:36 AM sun and fun
Title: Re: coro build anti stress machine Post by: wingmanbunty on August 11, 2014, 10:55:49 AM conclusion of the project
it is a hit machine i call it anti stress machine i am not expert pilot i can handle this airplane so does i think for other now i am trying to hover the airplane if got success will share with you thanks for all your support . :hatsoff: :hatsoff: :hatsoff: :hatsoff: :hatsoff: :hatsoff: Title: Re: coro build anti stress machine Post by: ponappa on August 11, 2014, 12:37:30 PM Cheers !!! :) :hatsoff: :hatsoff: :hatsoff:

Congrats on success. {:)} Single layer wing? Be careful of wing bending. See pic 'inverted2' in reply num 8. Wings bending towards undercarriage. Lovely photo! Title: Re: coro build anti stress machine Post by: wingmanbunty on August 11, 2014, 02:35:26 PM @K K Iyer
today is rainy day i was not able to go for work i am watching you on line and wait for your reply thanks for showing interest i use double rods for the strength of the wing yes it is single layer wing thanks again for kind words Title: Re: coro build anti stress machine Post by: v2 eagle on August 11, 2014, 11:31:15 PM Bravo Bravo bunty.
SO hows the feeling of first getting something up in the air? Ashok.P Title: Re: coro build anti stress machine Post by: vishalrao on August 12, 2014, 10:43:52 AM Wow! Surprised that flat wings can fly beautifully too! Would love to see the video. Cheers!
Title: Re: coro build anti stress machine Post by: iwincar on August 12, 2014, 03:25:13 PM #vishal rao surprised to see such flat wing to climb seamlessly.. {:)}
Title: Re: coro build anti stress machine Post by: wingmanbunty on August 12, 2014, 04:57:03 PM It is single layer wing ,i want to reduce wait ,but for strength
it has double rods . Title: Re: coro build anti stress machine Post by: vishalrao on August 12, 2014, 05:02:45 PM Isn't there too much pitch variations (nose up/down), especially during winds?
Title: Re: coro build anti stress machine Post by: wingmanbunty on August 12, 2014, 10:19:41 PM Thats the flutter kind of problem comeup with coro structure,i know you doubt about the single layer of wing ,the airplane is very stable ,no pitch problem

(Smoke test)as I call it :- very light adjustment of table fan airflow and smoke of burn sticks These are rough surface Flat wing as I use first it in my anti stress machine And finally the cut view of the airfoil used in anti stress machine to increase endurance and glide performance of the plane Result Yesterday morning made test flight The performance of the wing was superb I enjoy thermal with eagles and return back safely I also perform loops the smoothness is awesome I say to eagles “ye kar ke dikhaoo”(do just like me)loooop I suggest anti stress machine is complete from my design point of view wing perform beyond the expectation and really It is going to take all the stress Title: Re: coro build anti stress machine Post by: wingmanbunty on October 12, 2014, 10:59:17 AM test flight
Title: Re: coro build anti stress machine Post by: wingmanbunty on October 12, 2014, 11:05:05 AM coming out of thermal
Title: Re: coro build anti stress machine Post by: topalle on October 12, 2014, 12:00:55 PM Have you used any reinforcement on the wing sir?
Title: Re: coro build anti stress machine Post by: wingmanbunty on October 12, 2014, 05:05:40 PM it has dual spars and 3" brown packing tape covering ,it can handle small crashes easily.
Title: Re: coro build anti stress machine Post by: wingmanbunty on January 30, 2015, 05:04:25 PM anti stress machine , today morning flying.
Title: Re: coro build anti stress machine Post by: sahilkit on January 30, 2015, 05:11:14 PM nice plane, what kind of flight times do you get and how many packs do you fly ?
Quote BORN TO FLY FORCED TO WORK ;DTitle: Re: coro build anti stress machine Post by: wingmanbunty on January 30, 2015, 05:24:33 PM 10 minutes flying time with 900 mah 2s.
Title: Re: coro build anti stress machine Post by: sahilkit on January 30, 2015, 05:37:40 PM okay, AUW of the model ?
Title: Re: coro build anti stress machine Post by: wingmanbunty on January 30, 2015, 08:15:59 PM sir ji pls check the build log for all details . thanks.
Title: Re: coro build anti stress machine Post by: aman1256 on February 01, 2015, 10:28:51 PM That Are Really Good Photos Of the Plane Flying.I Really Like the Plane Its Really Awesome.
Regards, Aman. Title: Re: coro build anti stress machine Post by: wingmanbunty on February 02, 2015, 06:08:22 PM :thanks: aman
Title: Re: coro build anti stress machine Post by: VC on February 02, 2015, 08:44:55 PM I love the smoke test for testing the airflow. Lateral thinking at its best!
Title: Re: coro build anti stress machine Post by: wingmanbunty on February 10, 2015, 08:22:09 PM for increasing endurance i test fly airplane high above the ground , now when we are in a thermal can enjoy flying for long endurance
airplane glide so well with almost full throttle stick back. Title: Re: coro build anti stress machine Post by: wingmanbunty on February 11, 2015, 08:53:23 AM Anti-stress machine
landing Title: Re: coro build anti stress machine Post by: wingmanbunty on August 04, 2015, 02:21:12 PM The anti stress machine is so far my best trainer airplane, but I want to build some classic that do not have any aerobatics or not have much power, I want something that I can fly relaxing, which I do not have to do much on control stick, just enjoy the lazy Sunday morning, I build a Coro box and add another wing on it. Biplane ready to fly
I was expecting some very slow flying airplane and I got it I really enjoy the biplane conversion, if we face the airplane to very little strong wind it seems that it can almost hover at that place for some time.
