The Whisper.. and other Carbon rod and Film/Fabric models, including indoor...
Thread starter's only
basic fuz shape from 2,5mm CF rod
tail assembly ..bearing tubes hold stub rods which will take the tailplane halves and the fin
wings made in two sections.. main frame , then a tip bow... If you try to use a single rod all round the tip bend will distort the main frame
the half wing assembled..not perhaps as neat as a single rod, but all good and straight
An under cariage is made from a front triangle with a rear brace
the tail assembly
depron wheel with a tube hub on a 1.5mm rod U/C..restained with another bit of the tube glued in place..using a long hub tube the wheels dont wobble if the rod U/C is too thin
dental flossers are heat bent and make the horns
tail plane halves and fin get lashed to the stubbs in the tail assembly... make sure they are all lined up, square and even, as needed before you add the CA glue to fix them fully
weight here as seen is 27gms.. 3mm depron outer ribs and a 6mm depron center rib are glued to the frame with UHU por
Its only a fraction but on the reflective foil the change in lines is more noticed
Motor has a few degrees of down thrust.. The block is hot glued to a 3mm depron part.. the depron is glued to a very thin ply part.. this is to make later removing safer for the block
guide tube are supported on short arms.. lashed and CA'd like the rest
here its been bound to the TX and all the controlls adjusted... directions.. dual rates etc... all done
closer on the block... you can see the 3mm depron its fixed to, and the ply layer... this should make for easier removal at a later time..
there is a bit of a depron body, just a couple of layers arround the CF rod.. I put some tape over the body layers where the block is fixed.. the block assembly is glued to the tape with UHU then some hot glue was put along under the overhang
this arrangement of bends raises the rod enough to avoid the block
with a standard Z bend on the other end and an upright Z this end .. first connect the rear Z... then the CF push rod is twisted so the upright can be fed through the servo arm.. once through the twist is released and the upright will now keep in the arm.
with lights this is flying at 40+gms nice and easy
the basis for my idea
The fuz is done, but I got side tracked to the Whisper
Fuz ..now with repositioned vertical rods..tailplane brace added..stubb wing spars added ..and bracing thread
tailplane braced bearing tube
with tailplane and tailfin fitted.. some packing rods were needed at the back so the tailfin bearing tubes could be lashed in a more accurate line up
a matched pair with bearing tubes on the main 2mm spar...next to make another pair..
just the sort of links I am looking for
Building the Kolibri Slow.pdf
just the top set added here
Its getting hard to see from pictures where all the rods are going..too many lines and too many shadows
a small area of depron to take the gear on velcro strips
the servos are hot glued and lashed to the CF rods
all movingwing pullpull
cog from a small glider trial is showing 105mm back from the leading edge of the covered wing
decor by solvent based marker pens
mid air damages colliding with the Whisper model
now stripped with a body
3mm depron fuz cut TLAR
snapshot from the sketchup file
Myfobug-v1 with body.zip
the longer fuz gives good rudder yaw action
now it needs some decor..
just over 1sqft.... at 79gms AUW.... 2.67ozsqft this should give me slow fly cruise capabilities.. with 150 gms thrust it will have good vertical...
decor by marker pens the thrust measured at 170gms .. the model weighs 79gms draw 5A at max with a 6x3 gws prop
the horns lashing came loose and because it was separate from the rod the elevon could move and the horn stayed still.. the two should have been lashed together figure 8 style
mid air damages.. now I am thinking of going back to heavier polyester cloth material for indestructability.. the extra weight will not be noticed.
it only takes a few seconds to make alterations in sketchup.. or when you are building these things
its a simple build...
