hello everyone I took the courage and took the print out of the blubaby 42" kfm3 version now i am going to build the rudder and the elevator first. Then I'll build the wings then the monobloc then the fuselage.

Why are you going backwards? first build the fuse the wings then tail stabilizers
Build planes like feathers rather than tanks, both handle bullets equally well.

at the time of making landing gear , dont follow the traditional build for Blue baby, suggested technique of making landing gear is not OK. you can check my blue baby build log.

sorry for the poor quality of the pics
till now i have made the rudder and the elevator
the cut outs are of waste quality thinking to sand them down and smoothen them

I Appreciate this, Making the Airplane is much better idea then making threads on the RcIndia..

Good Going :thumbsup: :thumbsup:

Instead of using kfm3 I am going to use kfm2 airfoil
as kfm 3 will make the wing more thick.
so is kfm2 equal to kfm3 in terms of lift produced.

or I should go for other airfoil.

I've made many changes in the plans

I've changed only for the kfm2 and the slot where the elevator is going to fit in the fuse
please tell me a suitable airfoil

use the kfm3... why change a tried and tested plan???
.

aniket210696

use a 8*3.8 prop, as specified on the motor specs.... if you use a prop with too much pitch, it can strain and burn the motor...

I have changed because the wings will be too thick then

wow.. that's thick
. OK do a thing, make a kf2 aerofoil.

and don't forget to Sand down the whole thing... try to get some thinner thermocol

If it's low desity Thermocol, use CF rods for reinforcement and layer it with packing tape for strength.   :thumbsup:

That's what I am going to do anjan bhaiya.
@aniket sanding will make the foam more weak its already weak.

20mm should be fine for a 42" wingspan. Just sand the leading edge to make it more like a blunt knife edge.

if you  cant get cf rods, use strips of wood....though they might be a little heavy....

thanks I will use whatever I get
I have doubt will the above mentioned electronics will work perfectly for this plane
