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
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.
thanks mjet
Rc neil I am actually cutting the pieces till now I've cut the elevator and the rudder.
Please post the pictures of the build progress.
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
Go for it young man {:)} {:)} {:)}
All the very very best. BluBaby - great choice!!
I Appreciate this, Making the Airplane is much better idea then making threads on the RcIndia..
Good Going :thumbsup: :thumbsup:
hello everyone I am thinking of using this power combo will it be good

i guess you must be knowing which one
If any other alternative to the elecs please tell me.
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
follow the plans to the t...! don't change unnecessarily!
Sent from a potato using a lamp
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???
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
what thickness material are you using? post some pics...
Sent from a potato using a lamp
10mm thick normal thermocol.
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
Sent from a potato using a lamp
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.
Ok I will surely do it
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
read the part about the prop i posted earlier... an 8*6 might be too much for the motor...
this motor can also be used with a 3s so I don't think 8*6 is too much but if it is more then I'll change the prop
Sanjay sir thanks for your inspiring words
why dont you use a emax cf2822, with a 20A ESC, a 10*4.7 prop, and a 1000-1300 mah 3s Lipo?
this was the same setup suggested by another member via pm's but he told to use a 9*4.7 and 850mah lipo
that's good too
Sent from a potato using a lamp
will it produce enough thrust and will i get atleast 10min of flight time with it on variable throttle
850mah? for a 42" WS? thats a bit low, even a 1300mah 3S is good enough.
yeah that was the same question I asked
though the emax motor generates 700g of thrust... that's more than enough... get a 1500-2200 lipo...
Sent from a potato using a lamp
i started with the monobloc
it is made out of 1.5 mm foam pieces.
i will be going slow for this plane
Hello
should i add ailerons is it neccesary please reply fast.
and I am going to go very fast because before 10 min. I got to know I am going out of station on 18th so Please don't mind if I can't post the whole build log.
plane is getting shape
plane is getting shaped
