OK! Finaly my package arrived from AeroTetris Spain. The build can start.
First, numbering all parts. It took me aprox. 2hours.
Todays build. From section 1-9
Section 11-12
A couple of more sectons assembled today
at this point im at section 19. There are many pieces in every section so it takes time to build but it is super fun!
Todays build. Section 20-23
At this point the front section os only layed on top of the aft section, not glued. Noticed that its not perfectly straight so i have to adjust the top section by sanding it straight before gluing.
Day 3, Another tetris build day.
Wings and wing tubes
Time to fit in the EDF.
Im now at section 32 were i think is a good place for the EDF.
Here i have made two wood blocks to screw the edf unit in. They are glued in place with 30min epoxy.
Building the fin
Weight is now 422g That includes carbonfiber wingtubes and the two wood block motor mounts
Installing the servo for rudder.
Markings for rudder
I hope the size of the rudder is ok.
Gluing the wings to the fuselage using epoxy, not UHU!
Here i made a simple jigg to make sure the fuselage is perfect streight.
Wings seams to be in perfect level
Checking the TP.
Here i have straighten up the battery compartment with balsa.
Made a bottom plate in balsa for the lipos
The top hatch is hold in place with the carbon fibre rod. The rod is not glued so its possible to drag it out
Perfect fit of the lipos
