Designed by Josh Bixler....of HK Bixler fame.

I've never built a foamy before, flown 2 though (Easystar 2 and Multiplex Fun Cub)

Managed to get 6 mm Biofoam from Sitaram Stationers, South Ex. 1, New Delhi. Rip-off at Rs. 300 a sheet!!!!

Warning: This is not a beginners model!!!

Plans printed on a plotter

As it is printed on a plotter (very big printer actually) the finish will be excellent. :)

I missed the maiden :(
Very sweet build and superb finish...Really wanted to see the 3ft takeoff and the landing.

Rai Sahib, that is a stunner! Are you on your way to becoming a professional modeller? If there ever was an award for the most prolific builder on this forum - it would have your name on it. How many, so far, this year Sire?


Title: Re: My first foamy Scratch Build - Baby Blender
Post by: sanjayrai55 on October 16, 2013, 12:40:18 PM
Don't know VC sir  :rofl: Lost count  ;) ;) :D Thanks so very much :)

To transfer from plans to the foam, I use a sharp pencil and poke through at the primary points. Then I play join the dots :D


Title: Re: My first foamy Scratch Build - Baby Blender
Post by: sanjayrai55 on October 16, 2013, 01:25:35 PM
Build is fairly simple. However, the Flite Test swappable series goes together with notches slots and tabs, so you need a high degree of precision and accuracy in marking and cutting


Title: Re: My first foamy Scratch Build - Baby Blender
Post by: sanjayrai55 on October 16, 2013, 01:31:09 PM
I had bought some monokote (clone) from Ganguly-da of Lotus Hobby many many years ago. Decided to check if it had dried out :D  Worked fine

I prefer to put the trims before assembly


Title: Re: My first foamy Scratch Build - Baby Blender
Post by: sanjayrai55 on October 16, 2013, 01:34:37 PM
Sunburst design on bottom, stripes on top.

Had bought these "snake" pushrods a year ago, decided to use them


Title: Re: My first foamy Scratch Build - Baby Blender
Post by: sanjayrai55 on October 16, 2013, 01:41:45 PM
Swappable Power Pod. You can use this in many FT foamie models, it's a modular design you unplug from one model and plug into another 8) 8)

I wanted to fit the L/G on this, but as things worked out, it interfered with the battery :(


Title: Re: My first foamy Scratch Build - Baby Blender
Post by: sanjayrai55 on October 16, 2013, 01:52:46 PM
All 3 servos HXT 900. Motor is Turnigy 2826 1400 KV, and prop (thanks Girish!) is 9*47 SF. Needs a 30 A ESC, I only had a 40A so used it

Finally made the LG as per the plans. Didn't like the idea of so much load on the wing (I specialise in rough landings  :rofl:) but there seemed little choice


Title: Re: My first foamy Scratch Build - Baby Blender
Post by: sanjayrai55 on October 16, 2013, 01:59:40 PM
The wing hold-down rubber bands also keep the L/G in place. Good, else on a rough landing the bottom wing will get damaged. Should reduce that

Added a tail skid in the form of a small piece of Bamboo Skewer

Ready!! Finally :)

It's not in the pictures, but besides the flat velcro to fix the battery, I also used a velco strap.

It takes of within 5 feet and goes vertical! Throws have to be reduced - the model is too sensitive

sanjay sir that is beautiful! just a tip, if you laser print the plans, to transfer them to foam, put them face down and iron them... it will transfer the ink to the foam.. (mirrored though)...

Thanks Swizera - actually it's called Baby because there was a model called Blender. It was built for a competition, wherein a Blender was fixed to the plane and a milkshake was made  :giggle: :giggle:

sanjay ji , very beautiful. pl let us know , that Indian Biofoam is not laminated , what you did with foam to bend it for wing profile and control surface hings.

Mohan, if you see the build instructions in Post #1 - what I do is put a piece of tape on the back, and then 2 x  45 deg. cuts. Then bend to 90 degrees, put hot glue, and when dry take out the tape. For different angles use different angle of cut

superb finish when will i reach there :banghead: :banghead:  what was your experience with your first foamy scratch build sir?,i wanted to build a bipe plane but travel is the prob as wings are not removable,still thinking  :headscratch: :headscratch:,whats the airframe weight and auw of this baby


Title: Re: Re: My first foamy Scratch Build - Baby Blender
Post by: sanjayrai55 on October 16, 2013, 08:04:02 PM
Thanks Roman

With a 24" wingspan it is easy to transport. The airframe with thr 2826 motor is about 490 gm. AUW with 2200 mah is about 670 gms

Title: Re: My first foamy Scratch Build - Baby Blender
Post by: sanjayrai55 on October 17, 2013, 08:23:28 AM
Mohan, it just won't work out.

The weight will be more, the wing struts and their anchoring will be a problem.

IMHO with 2 mm corro one needs min. 40" span & 8.5 " chord. That will give you a model flying weight of 900 gms or so

Even a bipe with 24" span and 8" chord like the Baby will weigh about the same ie 900 grams. This will not have the same flying characteristics - you would have to use a more powerful motor, the stall speed will be higher, the descent will be fast and rapid etc.  8-) 8-)

How about this??
You seem to like Flite Test quite a lot now.
BTW, I've always wanted to build the Baby Blender, ever since they released it, but plan on getting into electrics before that.

Taitil, if you are using foamboard/biofoam, I suggest you build the fuselage from foamboard, and the wings from biofoam, thus keeping the weight manageable


Title: Re: My first foamy Scratch Build - Baby Blender
