Now that I have built a quadcopter, I am considering trying a plane. I have shortlisted the Flite Test scratch build series. I would like to start off with a smaller plane since I have limited flying space (24 inch span). I have decided to build one of these planes using Laminated Depron:
1. The FT Flyer (or Nutball)
2. The FT Mini Scout (Or Speedster).
I need some advice as to which of these I should go for. I would appreciate any other suggestions as well. I am not sure whether to go for the Swappables or Mighty Minis. I am completely new to scratch building and planes in general. I have some knowledge of RC electronics/ power and control systems etc. and I have been watching the FT Beginners Series. I would like to choose a model based on ease of building and flying and also it should be able to fly in relatively limited space.

Re:

Don't use laminated foam it's heavy.

As for the plane go for the blubaby 24 scaled or not scaled your wish.

I thought the foam used in FT builds was laminated with paper? What sort of foam would I need for the Blu Baby and where do I get it?

Actually, you can even look at the Old Fogey or the Speedster.
Check out the video of the FT-Speedster

Thank you for the suggestions sir. The only problem is that these planes have a larger wingspan and for me, space is somewhat limited. I am now seriously considering the FT flyer since it is supposed to be easier to fly than the Nutball though not as easy to build. i am going to get some Depron ASAP and build the plane before I get the electronics. Does anybody know where I can get ply for making the firewall? Are there any other materials I can use. Also, what do I use to make the control horns and where do I get the push rods?

As for what foam you should use, nitesh is right. Laminated foam is heavy.
Flite Test uses Dollar tree Foam which is pretty good quality. In India, the laminated foam we get is pretty heavy compared to Dollar tree foam and thus FliteTest planes made with laminated foam do not fly well (Look at Sanjay Rai sir's @sanjayrai55 FT-Spitfire and FT-Racer builds)
If you are building a FliteTest model, I would suggest using unlaminated Depron and covering the outer side (Only one side) with clear packing tape.  It's pretty strong and light as well.

Thanks for the tips sir. The only place I have found with Depron in stock is Edall Hobby and they have Depron either laminated in paper or PVC. WOuld this work? http://www.edallhobby.com/en/building-materials/587-high-density-thermocol25-mm-.html?search_query=depron&results=2 I have also sent a PM to foamybuilder. I hope to get some unlaminated Depron from him.

Cycle wheel spokes make very good push rods. They are available at any cycle shop near you. Not very expensive and are pretty stiff. They are 2mm in dia.

Sir, but Spitfire was heavier than expected. Slow fly models will not fly well if they turn out to be heavy

That was because of the Landing gear and the LG mount. The original did not have it

I had seen the thread of material sources already, the dealer mentioned has a minimum order quantity of 5 sheets. How does 32 kg/ m3 compare with the foam being used by the experienced builders here?

I was under the impression that it was the laminated foam board that caused Sanjay Sir's Spitfire to be heavy and hence was apologizing for my mistake.   Undecided

It would have been lighter with plain biofoam.

But then it would not have survived a single landing on our field  Giggle

@SK1701,
I would suggest the FT Flyer. From what I've seen, it is more stable than the nutball.

Do you have the electronics for it?
If yes, then posting the electronics you have will help people in suggesting a model which would fly with those electronics.

If you don't have electronics, then you should go with parts that will be of use to you in future as well. If you go with tthe Mighty Mini Series, and buy electronics for those, later you may not be able to upgrade to bigger planes without buying new parts.

Ok. I have decided on the FT Flyer. I am going to get some Depron from foamybuilder here in Bangalore and these are the parts I am planning to buy:
HexTronix 24 gram 1300 kv outrunner
Red Brick 20 Amp ESC
Avionic AV9A servos
WolfPack White 900 mAh 25C 11.1V
8x3.8 prop and 3mm prop saver
2.1 mm linkage stoppers (will they fit the servo?)

Is this setup OK? I would like a confirmation before ordering.

Well I built this plane and am using 2s 1300mah lipo with avionics motors and emax servos don't ue the redbrick 20amp it's costly at 750 get a better one for 680 from rcdhamaka.

Yes use the linkage stoppers.

You will have to melt the servo horn for fitting anything into it.

if want any help building pm me.
