this was sent to me by a fellow member of the hinterland model aeroclub. a huge scale c17

the details:

The four builders are shown in the image above. Colin Straus, the owner, is at the nose of the aircraft.

This 1/9th scale radio-controlled C-17 model was built in theUnited Kingdom. It was built as the centerpiece of a 15 program television series produced in the U.K. for the Home and Leisure satellite TV channel.

Built with the aid of three friends, it took one year to build and is powered with 4 Jetcat P-120 turbines with a total thrust of 108 lbs. The model weighs over 250 lbs fueled, and carries 12.5 liters (3.3 US gallons) of 95% kerosene and 5% turbine oil fuel. Other details include 5 Futaba PCM receivers, 16 battery packs (93 cells), 20 Futaba servos, on board air compressor, electro/pneumatic retracts, etc. Wingspan is 20 feet 8 inches, and the top of the fin is 74 inches (6 feet 2 inches) above the ground. Takeoff weight is 264 lbs.

The rear cargo doors open and they drop an r/c jeep on a pallet, as well as 2 free-fall r/c parachutists.

The model also has smoke systems both of the inboard turbines, and uses a 2.4 GHz dat a link to provide real-time data to a laptop computer on the ground while in flight. This data includes airspeed, turbine RPM, EGT, fuel consumption, etc. Built mainly from balsa and ply, with many glass and carbon fiber moldings to reduce weight. It is covered in fiberglass and epoxy resin. Complete with retractable landing gear and pneumatically operated flaps.

This C-17 Globe Master III is one of the largest jet models in the world today!

Far canal!


Can't imagine that thing taking off on the mown grass strip we had at the R/C club back home.

I wonder if there are regulations for something that huge... it would make a mess of anything it hit.

Far out, you might aswell just put a seat in it and ditch the R/C controls

Bigger models fly better. I bet that was the excuse he used when he told his missus he was gonna build it too

Do it! I love my R/C flying, but haven't had the time of late. I've got a whole spare room in the house full of R/C gear, much to the GF's dismay

I used to have R/C helicopters many years ago. If you want a good cheap R/C simulator check out this one: www.rcflightsim.com/help.html

It is quite life-like for helis so I assume it would be for planes to, not that I've ever flown a powered one. You just need a cheap gamepad.

Flying is cool but no no no get a car!!!

I used to race 1/8 scale buggies (4WD, offroad) and they rock. Anything that does 0-100 in 2sec and idles at 3000rpm with a 38,000rpm redline is way cool

Yeah, I must admit, it's a lot easier finding somewhere to run an 1/8th offroader than it is to find somewhere to fly my heli. Perhaps I should sell my airborne stuff and go into buggies

If my GF sees this post, I'm a dead man

1/8th nitro buggies are cool dont get me wrong,
but if u wanna spend more time racing and less time cleaning and rebuiding and tuning and cleaning more castor oil and more tuning and starting ect ect , then you should get a electric buggy .
i have a 1/18 scale electric buggy with LiPo batteries and 5.4 KV brushless motor .
absolutely rips , and the battery lasts about an hour or so going pretty much flat out the whole time . its a 4x4 but it still monos and spins all the wheels on the road for about 2 meters top speed is about 45kmh but with taller gearing it could go about 80.

Forget the Castor! Go synthetic, or mix.

And that must be one damn expensive Lipo

This is really creeping me out how many people are into the two hobbies, I too have a spare room dedicated to a workshop for my planes, helis and all else radio control.

I've just sold my heli and have some planes on ebay too. Should clear out a fair bit of space in the spare room, but I've just picked up an 1/8th nitro buggy (with the funds from the heli/plane sale ), so I'm at least keeping *something* radio controlled....

OK just to completely freak you out here's a robotic dog I made for a local theatre group:



6 channels (head pan, jaw talk, left arm, right arm, steering, drive) and I had to hook up my two R/C controllers to an XBox controller as I ran out of fingers to run all the channels.
Also I put in some bicolour LEDs, a microcontroller and reed switch so that he blinked his eyes green most of the time, except when his right arm is raised then the eyes flash quickly red (used when he is 'scared' in the performance).

The dog performed flawlessly for the three weeks of performances, and every kid there loved him.

They are the 2nd best set of rims I've ever seen on a dog, Have you considered racing it at the greyhounds? I used to do gas planes but have now turned to LiPo's, no cleaning required. Just gone EDF.

I was considering going electric with this 1/8th buggy, but I don't have a charger that will do LiPos, so I would have had to shell out for that as well. Plus, there's just something about the smell of a nitro engine

Damn it, who's been posting under my name! It wasn't me Stribo, honest, IT WASN'T MEEEEEEEEEEEEEE!!.
