Ours is a sheep paddock, and pretty muddy too.
Haven't built a full-bodied foam model yet, maybe it's time, and maybe this is the model.

cheers
Mind you the Cammo might also be a bad thing when ( always when never if ) those magnetic trees grab it.
The cows don't seem very interested, the Roo's usually run away into the bush accept one big one watches me walk down the driveway then up to where I fly, does not move just turns his head to follow me. I think he waits to see if I am going to crash.
I have a friend that lives in your area and he tells me it has been pretty wet and cold lately.
This is a nice Sunday driver mine weighs about 850 grams RTF, it is made of polystyrene sliced to about 3mm then covered with brown paper.

Very interesting!
Have also used the sliced poly method, very light, with a few balsa or cf spars/longerons, makes a good structure.
Dunno if I have any 3mm left, some-one said there were too many models and foam sheets inside, offered to help clean up, seems she has stooked it somewhere. (Lots of 5-6mm),
Have Roo's when I fly at home, can be inquisitive at times.
Anyhow, one Slowfly out of sliced poly coming up!

cheers

Tim,

I like the looks of your plane.
Is your tail wheel steerable?
Still haven't flown mine yet.

Believe it or not i did not even think of making the tail wheel steerable.
I just bent the wire up and glued it to the end panel, seeing you mentioned it
I will now remove it and make it steerable.
The main reason i put a tail wheel on was that my main wheels are about 20mm
smaller in diametre than what they are supposed to be and the belly was a bit
close to the ground. I used a drink bottle for the outer section of the wheels, and then foam board
for the sides, as the last one I made the wheels out of polystyrene and they just disintegrated
on the first hard landing ( the glide test ). so I made them more robust this time.

FYI / tips

I just put 1/2 of a Ping pong ball on mine, back at the tail.
It's Slides around just fine !

The tail has low loading and with a touch of down elevator
and a touch of throttle
you can get it to Stand Up on the mains alone.

Do Wheel landings with a little power on.
The actual stall is a bit touchy to predict due to the UC foil IMHO.
Stall = Slow Sink with this bird.

Extend the LG width away from the body which will add a little "spring"
for those not so perfect touch downs.

I put/laminated strips of very very thin ply down the insides of the Fuse all the way to the LG plate.
And the same ply across the top between the Wing hold down pins.
Some real small CF rods or Bamboo skewers from Shoulder back to tail on inside top corners of fuse.
Very little weight penalty and LOTS of integral strength added.

Strength where it's needed and Lightness where where it's not.

Now that is a good idea, I have plenty of ping pong balls on carbon rods from helicopter training gear, that I have been trying to work out what to do with.

In my tail section I installed formers at the lattice sections and a 3 x 1mm carbon stripe along the the bottom of the fuselage to the back of the cockpit . As in my last Slowly It seemed to have excessive twist in the back section.

My mate , over in Caloundra , has a Slowly that I sent him about a yr ago.

He is finding his to be an interesting flyer.

I'm the mate mentioned above, and it's true that building and flying this plane has been most entertaining.
My usual planes are self designed, foam scratch built, overpowered, aerobatic weapons or things for FPV.
When birdofplay sent me his excellently cut-out MPF tabbed version of the Sowley it propelled me into a whole new (for me) branch of the hobby.
Building someone else's design? What!
Not going from thought to foam without drawings? Weird!
RET? Hmmm! Don't know about that!
Anyway it was a fun build and is fun (sometimes funny) to fly and I'm impressed how well the big MPF wheels are doing their job.

The build and videos are here: https://www.rcgroups.com/forums/show...l-Build-For-Me
In the first post I mistakenly refer to it as a 36 inch version. In fact it measures more like 42 - 43 inches across the goofy dihedral I put in it.

Finally, got to fly my "Slowly" ,and it was heck tick.
Took off fairly quick and just kept turning left. Got into a tight 5 foot circle, almost knife edge flying. The trim was way out. Seems that I built my plane with the vertical stabilizer quite out of line.
To make matters worse, I kept trying to correct the turning left by using my aileron stick ( all the planes that I have flown, a total of three, have ailerons and that is where my reflexes kept taking me.)
Finally, I got full right rudder in the medium rate range to get "Slowly" straightened up.
I kept it in the air for a couple of minutes and then got in trouble again.
Made a quick hard landing as not to crash into the airfield's shed and broke a wheel and the axle.
Going to switch the rudder to my aileron stick, readjust the rudder to compensate for my poor vertical stabilizer alignment. Bought a carbon fiber target arrow at Walmart for a stronger axle and ordered some wheels off of eBay.
Hopefully, I will get things right. But, I was amazed that something that I built from scratch actually flew.

Congrats on the successful Maiden.

New build inspections need to be done from the front centerline
and scrutinized for wing warps , symmetry right an left,
and empenage "squareness", for lack of a better description.

I also mixed my Aileron and Rudder so that Either makes the rudder work.
No thinking necessary as either stick results in turns.

Those big FAT Multiplex , bologne round wheels made out of EPO are Perfect for my over sized Slowly. They add to comical "Look" of the design.

I expect to see a half dozen CLOWNS emerging from the cockpit !

By eye, my vertical stabilizer looks inline with the fuselage.
I will check the wing next.
The elevator worked correctly.
Thanks for the advice.

Been OFF LINE since a storm last Saturday.

Wing warps can be easily seen when looking straight down to Fuse
and carefully looking to either side.

Hey momo5400.

I like the pilot looking through the camera. very nice flight.
what motor and prop are you using.
