Here's a bit of footage of the 3 attempting to fly together last Sunday.
Not easy to do, especially with the low sun as they all became the same colour at distance!
Great fun though which is what it's all about.

Beautiful. If it arrives in the mag, I may do my third ever mag plan build. Following Nigel Hawes small Tucano many many years ago, and a PushyCat (the swoopy twin boom one). Still got both in my stash of 'benched' models.
Both great simple to build models 😎, you will like Shifty
I will get a materials list together in the next few weeks and post it on this thread, I am unsure of when the article will be printed though.
I will also start collecting empty 2 litre bottles in case anyone wants me to make them an optional canopy, I wouldn't want anything for them just the cost to cover P+P (doing our bit for the environment and all that).

Thanks for all the info gents and for the link to your excellent teferb thread Roy.
The mini Jim I have is from the stock that was present at the time of the shop fire.
Here is the other kit gifted, you can see the smoke damaged on the box but the contents are as new.

The weather finally improved for a few formites to get together for an afternoon of flying.
Steve's Shifty looks even better in the flesh and is a credit to him
I did manage to get a couple photos of it in all its glory but the light wasnt great.
We set up mine on Rich E's transmitter and he had numerous flights along with Steve's in formation (ish). I did get some footage but will need to go through it all.
The good news is that I've got to make another canopy for Rich E.
Here they are after flattening several batteries.
We had a good comparison over both of the models, Steve's CG is about 10mm forwards of mine which seems to make little difference. His motor is about 6mm lower which may be the reason for this, he's going to reposition it to match mine which is line with the canard and wing centre line.
As for trims neither have any dialed in which is reassuring.
One thing that was discussed was the ballast weight added to each, there is enough room to possibly fit a larger capacity lipo to give an even greater duration.
Hopefully a video to follow.

Met up with a couple of mates today for a flying session.
Rich has now finished his Gyroo II and has made a super job.
Here is a video I took of one of his many flights.
A few photos.
we also managed get 3 models into the air, I need to go through my video footage to see if I captured anything.
Great fun

Down this way it's a bit HOT and windy.
Chris...😎
I'm not jealous, honestly............

Interesting, must have been the normal thing then with pre built fuselages. I always thought the Slim Jim was the bigger version to the one I have.

I've been gifted a couple of old kits, a Graupner glider and a Mini Jim ARTF kit.
My dad informs me they were bought by his friend from a place called International Stock in King's Heath Birmigham. They sold the smoke damaged stock from Jim Davis Models after a fire apparently.
They have to be at least 43 years old as around the same time my dad and his friend used to fly off John Bonhams land in Cutnall Green and he passed away in 1980.
What surprises me is that it's an ARTF kit that is more than likely late 1970s.
Although in single figures at the time I do remember the Slim Jim trainer as it was quite appealing, so I quite fancy getting the Mini Jim up and flying one day and save it from the bin.
The kit comes with a pre built fuselage typical of its age and is quite heavy for its size (as are the tail components).The wings however are looking a bit sorry for themselves. Pretty much all of the veneer has come off, I would like to save them if possible so as to keep most of its authenticity.
The veneer is scrap along with leading and trailing edges but the foam cores may be OK.
I'm thinking that if they are ok I could sheet them in 1.5mm balsa.
My dad used to use copydex years ago, is there a better adhesive for undertaking this task?
A few photos of the old girl, if anyone knows more about these models I would be interested to know a little history.

They've scrubbed up ok Stephen, it's just a waiting game now.
Have you checked your thrustline position?

Looks great Stephen, needs some colour on those boots...
Fingers crossed this weather improves soon

Beautiful plane, weird prop!
Agree, but they are the recommended props for these bullet proof motors.

Interesting, my CG is around 85mm infront of the LE with an AUW of around 550g. I'm guessing the extra weight is because I widened the fuselage a tad to accomodate larger Lipos on the finished plan.
I'd be interested to know how yours performs inverted Steve, mine requires no pitch input for straight and level flight.
-
Well done Steve, your a braver man than me undertaking a maiden in todays breeze!
Glad it flies well and thanks for taking the time to build it.
It looks the business
We need to get some flying shots and video.
I will compare my CG with yours and see how close we are.

Here you go . Beta build complete.. Another great model Rich . If it flys like yours I flew last year it’s going to be fantastic 🤟
Love it Steve, great covering job. A taste of Mercedes W08 there for sure, just needs a couple of Petronas decals.
Looks like we have a race on our hands.
Out of interest, what's the AUW?

The end draws ever closer… a few hrs spent on this one !!!😎😎
Your just teasing us......

Chris,
Shame you can't get lite ply down under but I think you will be OK as yours is not that much heavier than ours.
Sounds a bit frustrating waiting for the motor, haven't you got Australian online shops you could go to?
My thrustline is parallel to the boom and 90 degrees to the mast, its an optical illusion as the models not quite square to the camera.
I've been out with mine again today, this time with the higher kv 4max motor and smaller prop fitted. Can't say that it felt any different to the slower motor.
I even managed to fly it at my local park this afternoon, kept it close in and managed to fly around the trees.
Good fun.

Hi Steve (no1).
Yes, I have gone with a push rod rather than a closed loop system, it's just easier to cut a hole in the fuselage for me. Mine is supported halfway across the boom with a tube simply sellotaped on so its easy to remove. Like wise Steve's is easy to remove but a little more effort is needed to mount the servo.
There are 3 completed models so far and all have needed ballast weight up front to achieve the correct CG ( not sure about Chris's yer?).
I've tried lengthening the nose and shortening the tail boom but the proportions just don't look right.
Unfortunately there are too many variables like wood mass, different motor weights etc.
So the easiest way to get around this is to mark a ballast area on the plan,the rotor disc area is good for a considerable amount of added church roof.
I think I added about 20g to my nose, AUW of mine is 1070g and it is quite floaty in calm conditions.
Steve, Rich and Chris will know doubt confirm their weights when they spot this?

Nice work Stephen
I am about to fit an available motor to test on my Gyroo II, this one is has a higher KV so I will prop it down to a 7 x4 and gauge the difference. It's the same size and weight as the turnigy one so there is no need to re-aligne the thrust position.
https://www.4-max.co.uk/po-2834-1680.html
I have been promising Chris for a few weeks to take a photo of how mine hangs from the motor centre so here you go mate. Hopefully it will help the other Beta builders too.
As you can see I'm above the vertical CG slightly as the airframe is anglled nose to the right a tad in this orientation. The string is the vertical datum and the tail boom is my thrust datum as I know its edges are parallel with the thust line. This seems to work well with this airframe, Steve J2's example pretty much matches this and there is another set up the same awaiting for it's maiden.

Great imagination Steve, looks like I will have to tint my canopy glass....
-
Its also worth keeping an eye out on Ebay for the magazine, they crop up from time to time.

NoPaniC,
I am pretty sure PDF's or digital files are not sent out for obvious reasons. That said, SARIK hobbies do post worldwide so getting a Gyroo plan to Belgium is not a problem.

Rich,
Bang on, next bay to Perranporth, I grabbed 10 mins whilst the kids were at the arcade (which probably cost me more than the balsa to build Shifty).
Pierce,
Good to hear, always a gamble with a new shaped model. Hope you give it a go when it arrives on our pages.
Steve,
Coming along nicely.
I've seen the office work you do for fellow Arrows Hawk owners so I'm not expecting a rushed /bland matt black offering like mine.....no pressure....

Cracking paint job

Rich,
That video was taken on a pretty calm day so not really slope soaring as such, there were windier days but I didn't take my camera. Beautiful place to fly though, I can see why the slope lads enjoy it so much.

Excellent, I didn't know.
No problem Ken, your top of the list mate regarding the canopy. We need to persuade the Wease to have a crack!
