If you're looking into buying some small rc stuff like clevises, motors or props, check out www.rcbazaar.com and www.rcdhamaka.com located in bangalore, they usually have basic stuff in stock all the time. might save you excessive shipping costs and customs hassle ;D

I painted a black patch, masked it off with that text sticker i got cut from a local sticker shop and then sprayed silver over it and the removed the text sticker to  reveal the black underneath. basically, just masking.

Hi Yash,

wow! design

i am building my first foamie,

may be a stupid question but i want to know how the wings are attached to the fuselge, i am struck there plz suggest.


yash10896

U can use hot glue or foam safe glue to attach...many people also use magnets to give extra strength... And don't forget to use carbon fiber rod for reinforcement.....
GL for ur build

Hi Yash,

Thanks for the reply, how ever my query was attaching 2 independent wings to the fuselage as against the simpler single piece wings.

Your wings look like flat wings the doubt  that i had was since the contact area of the flat wing against the fuselage is very less will it be a rigid fix?

so the carbon fibre rod/ bamboo rod be glued(inserted in to the two separate wings) through the fuselage

also wanted to know if flat wings generate lift equivalent to airfoil shaped wings???

Pls suggest. :help: :help: :help: :help: :help: :help:

you could try using bicycle spokes for strength.

In the image, i used angled bicycle spokes to get a proper dihedral angle and also strength, it will give you an idea of how to do it.  :thumbsup:
and you can see how it turned out in the completed wing, pretty sturdy.

Airfoil wings generate more lift than flat one that a simple answer..but acc to my design i can't use airfoil one i have used 10mm depron for wings for airfoil i need a more than one 5mm sheet to make wings...u can say i was saving sheets as i have to bring it from delhi..but as u wish both have pros and cons and anjan idea is also interesting u can try that..

i dont understand why you say your models cannot have an aerofoil profiled wing. besides depron isn't the only way you can build strong wings!
Time for you to build a hot wire cutter, brother. i get  my 2'' thick high density styrofoam from a local shop, they sell it as insulation thermocol, pretty cheap compared to depron. you can hot wire nice wing ribs with it, i glue the ribs together and use an aluminium U-channel at the CG line for strength and use packing tape over the styrofoam to prevent it from cracking and breaking in a crash.

Progress  :)
Recently installed motor mount with araldite will leave till morning  8-) ....made pocket for battery will stick it with velcro  :giggle: ...having some problem on installing servos for elevator....can't decide about putting two and connecting with Y-Cable or making a custom Y Bend wire  :headscratch: :headscratch:.. Any suggestions????   :help:
