RC India

I have been wanting to build a light weight, slow flying, simple to build and very stable plane that beginners would love to fly.

Here are the specifications:

Wingspan: 760mm
Fuse length: 550mm
Chord: 150mm

Please forgive me as the size of the model has nothing to do with the name of the model  :giggle: However, it's going to look like one.

It would be a low cg design. Benefits would be:

1. Very very stable.
2. Doesn't require landing gear (Beginner's nightmare.)

Disadvantage would be flying in windy conditions. Due to it's fuse design, it will be very sluggish to turn in windy conditions. Only maiden will tell the complete picture  ;D

Attaching photos of build...

Fuse material is 3mm biofoam laminated with clear tape.

Attached formers (7mm biofoam, width 20mm).

The other side of the fuse cut. This is not cut according to the dimension. Slightly excess is left.

Have used hot glue to glue the formers. However, will use Fevibond (rubber based adhesive) to glue the other side of the fuse as the area to be glued is large and hot glue will set soon.

As fevibond will eat foam, have taped the bare foam surface first and then have applied fevibond.

The other side is then glued and excess cut carefully.

Fuse ready...

About 40gms

Looking good, Vishal  :thumbsup:

Thank you Sanjay sir!

Coming up very well Vishal.

Good going Vishal  {:)}

Power plant and electronics:

Motor - Motrofly 2204 KV1600
ESC - ZTW Mantis 12A
Servos - EMAX 4.3g
Battery - Haiyin 7.4V 500mAh 20C

1. Cut door for accessing electronics
2. Fixed motor
3. Fixed servos

Wing getting ready...

Maiden on Wednesday  ;D

@vishalrao,
This model is begging you for floats ;D
You can make it work as you demonstrated some months back. Just right for the monsoon...

That will give you a second Sweepstakes entry without building another model ;)
Regards.

Nice Build Vishal sir  :hatsoff: :hatsoff:

@K K Iyer Thanks for the inspiration sir! Will think about it. Sounds fun.

@Nithinraj Kotian Thank you Nithin :)

Wing ready...

Electronics access door, wing holders fixed...

Push rods made...

Model ready for maiden tomorrow  ;D

AUW: 196gms

196!!Wow

Vishal, I think you make them from papad  :giggle: :giggle: :giggle:

@vishalrao,
In the test flight be prepared for inadequate directional stability, poor rudder response and dutch rolling (maybe severe)

This will be caused by too much side area ahead of the CG.
(This is what i faced with a deep bodied old timer type. Compounded by low power and tail heaviness ;D)

Best of luck.

Suggest frying/roasting before use, to increase rigidity  ;D

Mission accomplished! Here's maiden video...

No bad tendencies. Turns well. Flew for about 7-8 minutes. Drained half the battery. Requires 5gm nose weight.

Here's another of me trying to catch it...

Nice flying  ;D

nice one vishal bhai..... awesome

Thank you Rajesh and Jayant :)

Really nice flier/flying Vishal  {:)} {:)}

I think in the second video you had added the 5 gm nose weight

This is not ordinary, but Masala Papad  ;) ;D ;D

 :rofl: :rofl: :rofl:

Thank you sir! No, all the video have the 5 gm lead nose weight.

Here's the first launch without masala... I mean lead weight...

@kamalsahai Thank you! Will post the drawing by tomorrow.

Very nice Vishal.

Thank you Ashok sir :)

My god sir,that is one amazing plane.
The least weight i have ever reached is 260gms,probably i'm a little too easy with the hot glue :P

Thank you Priyum :)

Attaching plan of the Whale...

awesome :thumbsup:

@vishalrao,
Kit it, sell it.
As a proven product!

thanks

kp

@ wingmanbunty Thank you :)

Iyer sir, yes I'm considering that. Thanks for the motivation  :thumbsup:

Will start another build thread on slightly modified version with landing gear. As I also see the lack of landing gear as an hindrance to beginners as well.

Gd one Vishal Sir

Great like always
