Big T 40 power model is on the way.  Based on Dave Clarkson's THUNDERER, but a little enlarged.  K&B 40 power.  Rear fin with AR and VIT worked via a Sellig timer.  Hard tank crankcase pressure.

Wing semi finished, over 6'6" span.  Still lots to go though.  Hope to have it finished mid year.

Why Big T?   THUNDERER and TORP. 40 so sounds about right I guess using the T letter.

Gos, looks like a larger Galaxie wing! Should be a great floater with the high aspect ratio wing. The K&B 40 you're using, is it the 6.5 or the 40RR version? I'm in the middle of building a class C Satellite myself with the 6.5 K&B as pwr. Keep us posted on the build looks really good.

So many kind remarks......well mostly I guess. Tongue

It does look a bit like the Galaxie.......your right.   I did build the large size Galaxie about 40 years ago with an extended fuselage......fin on the rear, AR and VIT.....ST29 power, and it went okay.   
Do a Google on Dave Clarkson THUNDERER and it should come up with a plan to give you the idea of my wing.

The K&B40 is a Series70......fairly old engine, but I got it from a buddy here and it's in good nick.......enough for me to handle I reckon.  The wing is just over 700 squ. inches projected area......ie. as it is with the polyhedral in it.

I need to add my good Wife took the pic and of course caught me blinking........she hates taking pics so there was no point in asking for a re-take.   Will put more pics on as we progress.

Been doing a little building on Big T.   Stab. is done now and will be covered later on as well as the wing.

K&B 40 will hopefully pull it up there.

Have made a bit of a start on the fuselage.......cut the sides out.  I'm in no hurry to finish it.

Very nice , still working my way up to the big ones.
Models from the Dave Clarkson stable had a good showing in our state Slop champs last week with Noel McMillans 455sq PAW19 second and I my 525sq K&B20 model first, they climb fast and glide very well.
After the Open Rubber and Slop contests Noel test flew his Dave Clarkson Trainer with a K&B 29? but it looped on launch for reasons unknown and sustained a little damage.
Next model on the board is a W Hobby kit Sija Mk2

Still plodding along on Big T.

Stab. is covered.  Esaki Lite Japanese tissue in red, then double covered in red Starspan doped on.

Wing inner panels white Polyspan covered top and bottom.    Tips underneath as per Stab.   Tops to be covered next week.    Black lettering and AUS # on top of inner panels. 

Fuselage.   Rear covered from stab. mount to very rear including fin with red Starspan.   From stab. mount forward to front some sort of light white tissue doped on.........Anybody have a couple of sheets of lightweight white Modelspan they don't want?   

Front to rear of pylon to be sprayed with deep red 2 pac.   Rear of pylon to stab. mount sprayed white.

Should be finished in June at a guess?

Thanks Craig and John..........Now all I need to find is a square mile of open area with 2 inches of grass all over. LOL.

I need to fire the engine up.......maybe at home if all the locals are out.......it's not been started for over 30 years.   Can get the glide right close by, but after that?HuhHuh   Perhaps the Nats at end of year?Huh?

Nice looking beast Gossie. launching one of those must be a real adrenalin kick - lots of noise and fury.
good luck with it,

John, there's nothing more exhilarating than preparing to launch a power model with a big honkin' engine, that's trying to tear itself out of your hands and get free.

I even get that terrific kick out of my old Rossi powered things.

I can imagine that too. I still remember being impressed by a young West Ausssi modeller launching a DixieLander with a fine running MVVS at a Nats at Camden NSW. He lost it during the contest.
It was probably a little tame compared to your Rossis and 40 powered model.
Good luck with it.

Camden Nats?Huh?   Would that have been 1974?Huh?   I think that was the last one there?Huh?   I only ever went to one Camden Nats. that year.

I was at that one and had built a rather large power model for a Rossi Mk2, as at that time I felt the larger the better to control the power of the engine......I'm afraid it was a flop.
I can still remember flying something or other over the river that was there, and getting myself through nasty thorn bushes then crossing the river to get the model then back again.......No wonder it was the last Camden Nats.

You could be right Gossie - It could have been 1974. The young West Ozzie's model i mentioned also went across the river and I remember joinging his search party and swimming across the river in our underwear and then searching on the other side for an hour or so. We never found his model - he was really keen on getting his hot MVVS 2.5 back.

It was a stinking hot nationals and I also rememeber taking regular walks out to a garden in front of the airfield to stand under the sprinklers and saturate.

As a spectator I really enjoyed having all the disciplines in the one area - certainly one of the last nats to do that.

I competed in many Nats after this but in RC Glider - well also a bit of chuckie and EZY B.

I have just been talking to Ian Dixon,we both think the young power flyer from WA would have been Paul Drayton ,Paul dropped out of modeling and went full size,he was the guy who hired a Cessna and flew around over the flying fields at the 1976/77 Bunbury nats, I think a photo of a RC glider taken from the plane got into Airborne?
He managed to get an apprenticeship as a airframe fitter,a position I also applied for,shame was he quit straight after his time and joined the police force.
Paul had a lucky escape when his Corby Starlet had its engine cut and landed in a shallow swamp tipping upside down,he now races speed cars,last time Dicko saw him was while being pulled over by Paul for speeding.
The only other young flyer it could have been was Steve Coy who also flew Coupe

Oh dear me......I've been found.

I had three of those ORCA F1C models with Rossi's in them, and yes they did go to the '77 WC in Denmark.  They were all on trim before I left Australia, and we practiced for 3 days before the main event, and all was well.
I flew first out of our F1C fliers and was given an overrun......Could not believe it, as we were all taking care to run just over 6 seconds,so I got out #2 ready to fly if #1 never came back in time, but it did.
Set the timer, fueled up and as the others had flown and I had plenty of time I waited until I felt it a good time to go.  On with the glo lead, into the starter and away..........ANOTHER OVERRUN......Absolute rubbish, but the timer was adamant, so I just shrugged my shoulders.  Both flights in cool early morning conditions had been 180.   Dave Anderson our team manager wanted to protest, but I said no, I'll just fly the next 6 rounds "for fun".  I ended up 54th.

Perhaps the only good thing was that even on 6 flights I had the most seconds/time up out off all our other team including F1A and F1B.   We did have a great trip/holiday though.

Thanks Phil,

Yes I think it was Paul Drayton. He was flying with a mate and both had Dixielanders.  He would have been only 17, or so at the time.
He came over to NSW for a while a few years later and flew RC glides with my club – Heathcote Soaring League.
If Dicko ever gets pulled up by him on the road again Grin – ask him to pass on my regards - John Haren
