Thanks guys!
Erwan though I didn't show it I've got a spring starter on the back, they've been nice to me over the years on other engines so digits crossed!
andrew wallace:
I like the idea of that just like a cox .049 engine :lol: I've been hit so many times by zenoah 62 I don't like using it :shock: once you got it going it stayed going it was just getting it started :?
selleri:
In my experience they like to be WET but not too wet, lol.
It can be a fine line!

I've started to ponder over the wing and the next steps.
Notice the nice Cyparis I picked up at Cosford back in 2006
Bought the first bits for this build back in 2004 so if all goes on according to plan it will be a five year(yeah right) project when finished.
Here the shims are flat while the ribs are glued to the bottom spars.
The wing will be split outboard of the flaps so W8 was doubled. Next two pictures show the the wing tube holes more clearly.
Moving along.
Here the shims have been put on their edge and we can glue in the leading edge spar, top spars and some more sticks and stuff.
Better get the angle of the root rib correct.
And here we are today.
And here we are after today, I also started the other wing half but that is just copy/paste work so no picture of that part.
Starting to look like something
Bottom of the wings has been sheeted.
Bigger flaps might be needed. :lol:
Oho, what happened here? :shock:
I wonder if these nice little rings have something to do with it? :wink:
The wing tube was bought from Ralf Petrausch Modellbautechnik. Pretty impressive stuff from them
The wingbolt goes through the balsa block on its way to the fuselage.
The flap actuation rib and blocks for the hinges.
Rolled up paper was used for servo wire guide, thin CA keeps it solid where needed.
Dowels were used for anti-rotation with a bit of plywood for holding power.
Decided to go with tongues.
Voila! Only thing missing is a bit of balsa to box in the tongue.
Caps for the wing tubes.
Attached.
Flaps.
Top wing sheeting.
And the LE, you might notice that there is plywood under the balsa on the center section.

I've started to work on detailing the fuselage, 1/64" panel line tape from Fighteraces as was used on the empennage.
Getting there!
Decided it was time to plug the hole round back.
Bit of filler, sanding, painting and we have this.
The dashboard, well, it's not white anymore.
One of the flaps is covered.
Almost done with the wings. One aileron left to finish, aileron hinges, wingtips, servo installation and who knows I might even manage that and glassing before Xmas.
Notice the curve in the ailerons, we'll get to that in a couple of years!
The wing has been joined... not getting any smaller.
Wingtips cut from a 3"x1" balsa. Currently the wing is weighing in at 2.6 kg(5.73 lbs) so the wing + fuselage is 5.2 kg (11.46lbs)
Nothing big happening, wingtips have been cleaned up and servo hatches for the ailerons made up, plus a lot of sanding and filling.
Always fun when you can assemble the major parts for the first time
The wing center join was glassed.
Started to lay up the cloth for the gear doors.
Carbon tows.
More fiberglass cloth.
Started to glass the wingtips, used a tad of a grey colour pigment.
Well I was a bit closer to the suggested daily dosage of the pigment today.
I began by placing a brown parcel tape on the center section to keep from having a single large wing tomorrow.
Then I applied some filler(P38) to the wing end, maybe a tad too much here but I got away with it, I hope. :lol:
Then I pressed the wing end home, allowing the filler to squeeze out.
Then I removed most of the filler that squeezed out. Tomorrow I should have a nice clean edge at the join.
Red circles show where the filler had grabbed the tape a bit. Better stick to better known brands in the future me thinks.
Here we see how the filler has spread out, besides giving a neater seam it also makes the panel more solid when attached.
Voila, nearly invisible seam, well it will be when I've blendid it in and filled in the area around the joining tab.
I offered the wing to the fuselage tonight, I was rather pleased with fit even if I say so myself.
I'll also need to fasten the wing to something.
Hard to believe it's been two years already, so a good day to mate the wing and fuselage and do some drilling.
Starting to look the look.
Threaded inserts were used for the wing bolts.
Time to do some cutting on the bellypan, made a W2 rib for a rough outline.
Tada...
...well almost, had to add a bit of material on the other side. :oops:
