Yesterday built a very simple pusher type plane . I had only one 9gm servo left with me, so used it for rudder. Elevator trim with Sellotape ;D Flew pretty wellon first attempt itself!
Specs:
Motor: Avionic 1600 KV outrunner
Esc: Mantis 12 Amp
Lipo: Hayin 500 Mah
Servo: one 9 gm
TxRx: Flysky 6ch
Building materials: fuselage- 1.5 cm thick usual Thermocol piece+ 3mm thick carbon fiber tube 50cm long
Wing - 65cm* 17.5 cm depron , dihedral
Tail- made of depron
Video just now shot ;D http://youtu.be/m3NBb8SEwYA
Very nice can you share the plan.?
Yes sure .All you need is
1. This motor - http://www.rcbazaar.com/product.aspx?productid=2397
2. 10/12 amp esc
3. A lipo -I used 500 mah
4.two servos
5. A carbon fibre tube of about 50cm length.
First make a wing of around 65 cm span and 17.5/18 cm chord. Dihedral is easy to fly.
Then cut a thermocol piece in shape. The height where you mount motor should be such that your propeller ( I used 7*5 apc ) should have enough space to spin.
Using hot glue attach the wing to the top of the thermocol( cover the top with Sellotape piece so that you won't burn thermocol with hot glue) when you attach the wing, leave some space at the back so that motor can be mounted.
Now hot glue the motor to an inverted "U" shape of depron so that it can be glued to the top end of thermocol .
Next, attach the stab/ rudder to one end of carbon tube. And then glue the tube to the thermocol body at an angle so that the front end of the tube is at a lower level.
Now connect all the electronics and make sure the cg is ahead ( of 1/3 from LE of wing)
Attach a landing gear which doesn't add too much weight(this I am yet to do😊 didn't get time)
And that's it! 👍 try it! And post pic/ vid. Any help if needed, ask me(here)
Plan I'll draw and post soon.
Make sure AUW is less than 170gm for best results( with this motor). I used usual rubber bands across the thermocol so that the wing is sturdy .
Awesome sir !
Tail doesn't look good because it is scrap ( from a previous plane) , used it to save time😃 The thermocol could be smaller, I cut big one because I thought even if I use bigger prop, this should suffice . I'll modify it to make it more beautiful 😃😄
@a3ruz , thanks👍
sweet! great work
@Girish👍 thanks.
One more thing, if anyone is planning to replace it with a better motor( of more weight) , then choose a higher lipo to balance the plane. Then make provisions to keep it in place( difficult to paste it over thermocol) , but may wrap it in place.
Modified a bit-1. Attached a self made box ;D to keep the lipo, 2: reduced height of fuselage 3: Attached landing gear. 4: 6gm FPV hd camera in front (:|~
Thought of giving it proper ;D shape; so fuselage built with depron.Lipo/esc went inside.AUW 160 gms. Truly a beginner pusher.
This motor also will suit http://hobbysea.com/products.php?21&cPath=127&sid=906e41bf1a815512c7987ec8d8c3a8d9
Flight video? Really nice and simple design!
Hi Nitesh, maiden (fresh) video for you :) It requires 1. Elevator trim (since it doesn't have a servo , fixed) 2. Rudder trim (since the videographer is difficult to get( he is busy with his own plane builds :) ) , I could not trim it properly. 3. Tail heavy since the plane was balanced with camera in front, which is not attached. Anyways , enjoy ;D.

Today evening this plane has served its purpose.😃 ;D Found a place in its home , the sky ,with beautiful videos from above :)

Absolutely right.
Not a candidate for a beauty contest, but would easily win a duration contest for models with battery limited to 2s 500mah, and field size restricted to tennis court size.
You have achieved reliable outdoor flight in severely limited space, something I never got around to doing.
Well done. Congrats.
Try a bit more downthrust!
I am going to build this thing and fly it in a park near my house! I will use a bigger motor, battery and prop than the one you used!

And fly in a bigger field, i guess.
SI74's biggest achievement is that he can fly in his backyard!
Thank you so much Iyer sir! I'll reduce the elevator trim for a better, stable flight. ( since today evening had perfect weather for outdoor flight, I didn't waste time modifying it) And I know "need is the mother of invention", one of the reasons why I prefer a slow flier with less AUW, since I have a rather small backyard for my leisure time flights.
And Nithesh, if you plan to use a bigger motor/ prop, it is better if you follow ramarao's design.
I am going to increase the wing size and then fly. I am going to start work on this today and fly it by this Sunday. I am going to modify my FT flyer.
How many I am going to's?. Let's just shut up and build this plan Nitesh.
Nice idea...:) good and simple plane.....:)

I will Sir, I will fly it in a bigger field! I will fly it in a park which is near my house.
Edit: Build Started I have already built the wings! Build thread coming soon.
Another good motor ( best among the three) , but price has gone up (by 355 Rs)

funny looking plane.
Yes! :) and real fun to see it fly and record video :)
And it has simple accessories ;D attached for night time flying :giggle: Attached CR2025 cell ( used in calculators or remotes) to a colored led 😝
Built a bigger brother ;D (to test my FPV kit http://www.quadkopters.com/product/fpv-kit-and-accessories/fpv-kit-mini-5-8ghz-600mw-32ch-txrx-with-mini-600tvl-camera/ ) And yes , it is another excellent slow flier . Pics & Specs attached.
For a beginner, AUW may go upto 380 gms,(light park flier) with this config; even though the motor can give (up-to)650 gms of thrust.
Simplicity at its best sir...... :D
