Title: Scale Balsa Plane build guidance
Post by: Dinesh.fly on November 25, 2015, 05:01:26 PM
Hello
I'm looking for guidance to build a scale balsa plane from a downloaded plan.I have the materials,could anybody be there in person and teach me the building? I can even come to your place with the materials to learn the building.I would be so incredibly thankful for this.

 :hatsoff: :hatsoff:

@dinesh.fly,
Last year a member Adiboy had a similar quest. Bit he ran away after 2 days as it was too much work!
And it was not even a scale model. It was just this:
http://www.rcindia.org/electric-planes/sunbird/msg239836/#msg239836

If you are REALLY SERIOUS, ie, prepared to spend Rs 1 lac or more, you should look at flyingboxcar's Tiger Moth thread

If you are merely INTERESTED, and want to start with SCALE models in BALSA, you should get a Guillows kit (24" span onwards, i think available in RCB)

If you want to SCRATCH BUILD, look at outerzone.uk for plans, select one (preferably a simple one from some 6000 choices)

Then you can consider coming to Indore, to explore possibilities from chuck gliders to jets...
Regards

Edit:
Meanwhile you can look at the posts of (bangalore based) ashok baijal for Fokker DVII, Me109, and many other goodies.

You can really start simple on this. Even i started by watching utube videos. There are lot of build threads in this forum especially for the sweepstakes. Choose a plan within 30in from outerzone, without dihedral. Then most of your work is simplified.

First thing first. What plan is that you wish to build from? That would help us help you better

Well Balsa kits are available and can be made easily fri=om the build instruction given with them.  The plan is full scale and it help in the build as the model is built on the plan itself.  PLEASE DO NOT BE DISHEARTENED BY PEOPLE SAYING THAT IT WILL COST YOU A BOMB.  My suggestion is:-
1.  If you are new to Balsa Kits and models, try and build a simple balsa model before venturing into a scale one with out the precut pieces.
2.  If you are OK with a simple model first then decide what kind of model you want.  Be it a electrical motor powered or an engine powered one (generally a Glow Plug engine is used).
3.  Decide what size of model you plan to make and then decide on the powerplant for it.
4.  A simple Balsa model with an engine should require a .25 - .35 Cu in Glow engine.  A bigger one can be of .46 -.50 Cu in Glow plug engine.  If you want to go bigger then the Sky is the limit.
5. With a .25 - .35 you can have a good trainer or an aerobatic model of up to 40 in span or so.  a .46 + will give you a bigger model of about 5 ft or bigger.  If you are going for a glider then a six ft span glider can be taken into the air easily by a .15 - .25 glow plug engine.
6.  I will suggest you to contact Vivek Sharma of Sharma Models for the assistance.  His trainer model kit will cost you about Rs 3000 or less and the same for the glider.  You can get the same thing as almost ready to fly at about Rs 6000 - 7000.  But I would like you to buy the kit and then make it yourself.
7.  Vivek Sharma's mob no is available in the RC Gems list of sellers here.  Or you may just put it in the serch on this website itself.

I have been into Balsa planes for far too long and have loved building them and flying them.  Go ahead and build yourself one.  Later you may get into the scale models when you are a bit more comfortable building a blasa model.

best wishes.

@dinesh.fly
If you're looking for static display models, it's different story, and perhaps a different set of members would assist.
However if you are looking for a flying scale model in balsa, without engine, motor, electronics, radio control etc, that is not terribly expensive,
Please take a look at this:
http://www.modelaviation.com/PC6Porter
Available for Rs 1250 from RCB (cheaper than US price!).
And in stock, unlike most other similar models.
RCB site also shows a flight video.
This is a fine way to get into balsa scale models.
Guillow documentation and instructions are absolutely excellent
The only catch is that you have to be prepared to do some fine craftsmanship. She just won't fly with sloppy workmanship.

Since i'm not able to locate where my old Guillows 36" Cessna 172 kit is, i'm inclined to get myself a Porter.
(RCB shipping is a bit expensive...)
Welcome to the fold.
Regards.

Iyer sir
That model besides accurate building skills would require light weight covering skills as well and then the complexity of rubber motor winding and maintenance. And we are not even talking about FF trimming skills required for satisfactory flight performance. A 40 size (or smaller) slab sided model with reasonably scale looks is what would be best for the fledgling builder. 

But we are all shooting in the dark. It is the OP who needs to clarify what he wants to do.

@flyingboxcar,
Capt sir,
I fear i got carried away by thoughts of what i could do with 80 24" strips of 1/8sq balsa.  ;D

After all many of us (you and me too) probably grew up on stick and tissue, before building slab sided 40 powered Cessna lookalikes.

Since OP mentioned balsa and scale, just gave an entry level not too expensive suggestion.
And i did mention that the catch was fine craftsmanship...

Guess i could have led him to my Indore Bipe, calling it a stand off SE5. Which is not too bad, even if i say so myself...

@dinesh.fly,
Sometimes I go off slightly at a tangent, especially in responding to senior members.
Dont mind, we'll not hijack your thread. And all inputs are well intentioned.
But quite often, these diversions may actually be of value...

In your thread, as flyingboxcar says, we're 'shooting in the dark'
For example, when you say 'balsa scale model', we don't know whether you mean:
1. Static or flying
2. Solid or built up
3. Unpowered, electric or glow
4. RC or not
5. Micro (6"), small (24"), medium (36-48"), large

So if you mention more clearly what you are thinking of, you may get more relevant suggestions than my flights of fancy!
Regards

I think the OP has got scared off with the barrage of (well meant) advice  :giggle: :giggle:

I would agree with Shobit though - Sharma models has some good options. A newcomer would be well advised to forget about scale - go for something like Orange Box which flies on 2/3 channels and with any of Electric/Nitro/Diesel, and is an excellent model to learn on

This is it: http://aeromodelsupermarket.com/radio-controlled-model-kit/45-r-c-glider-apple-box.html

Oranges or apples? No worries  ;)

Well... I flew the Orange first and then the Apples started to drop and I got hooked to the Apple.....  I am sure you would understand what I mean....... ha ha.... it does not matter actually.

Thanks for the precious inputs senior members  :salute: .It seems from the comments that as a newbie building a scale plane as first will not be a good idea.I want to build a RC model so will start from a trainer.

Call Vivek Sharma......... he has an excellent trainer model of Balsa and it can be assembled very quickly as the parts are laser cut and they fit well.  It can run on a small more and a 8x4 prop.  Needs a 4 ch Tx set.
best wishes
