Wow, an orange Gripen. I like it. Although it may be a little sickly after a while [:'(]
I like the idea of a two seater, it looks great. The only problem is the delay. Reading Johns post I suppose I could always convert it to twin seat later on.
I had a AMT Olympus in mind for this jet. Any idea of flying weight yet???
I am with Rocket man on this one. I know that for some people the size of this model wont be practical, but honestly once you have flown these 1/5th scale jets and you realize how well they do actually fly you realize that sometimes impracticality is unimportant [>:]

I think this plane is gorgeous,,, but you are right about color schemes,,, I just wish they would do the twin seater,,,, WHY DON'T THEY DO THE TWIN SEATER.

Does anyone have a movie on this 1/5 scaled beast in action ??

Or perhaps some more detailed pictures of the airworld gripe ??

There should allready be a few of these out there flying or in construction...

Anyone got more info, pics etc.? Dave W., Ali M., anyone?

Especially interested in hydraulic landing gear. I have no personal experience with hydraulic systems - sounds great but how's the setup, reliability and maintanance?

Considering this my next plane, probably with P200 power...

Would really appreciate any input!!!

SAAB makes it. That's somewhat larger than (about 5 to 1) Airworld I think...

...and to answer myself, there's nothing wrong with grey... Or white as it arrived just a week ago!

In the 4th pic. there's also a 80mm wheel from my Rookie II to give some idea of the size of main landing gear...

Hello,

here is a picture of my Airworld Gripen
[img][/img]

I've a couple of flights, but snow arrived in switzerland before i found the final settings for pitch control.
See here [link=http://www.youtube.com/watch?v=nPW0Ow_TEWI]http://www.youtube.com/watch?v=nPW0Ow_TEWI[/link]

I like the hydraulic system. I have all, gear, geardoors and brakes on hydraulik. They move very smooth.
For power i use a JetCat P200. That's excellent for this model with 19.1kg dry.

Regards
Martin

Hi!

Great video Martin! Nice to see someone else interested in Gripen too!

I'm also putting a P200 to the plane. Are you using the recommended CG and control throws? Could You please share with us the hardware you used for gear doors/brakes - valves, cylinders etc.!!!

Rgds, Janne

Main gear installation.
Doorzylinders are from Robart.
Valves are all from Peter Hausel (MTH), he has also a proportional typ, wich is good for the wheelbrakes.

Nosewheel:
Zylinder should have a stroke of 80mm, Airworld delivered first with 105mm stroke.

I got my AW Gripen a week ago,and it looks good.I am looking forward to build it.All the fiberglass parts i very fine.
The things I don`t like is that there is no full ducting and there is missing parts to bolt the gearcylinders to the fuselarge.I am gone use P200 for power and I am looking to fly this plane

Thanks Martin!

These will be of great help!!! Good looking setup with the gear doors - that must be the hardest part building this plane. At least for me it is!

Hi Tom!

I'm also missing the ducting, which I don't think is absolutely necessary anyway... (in a functional way i mean - for scale something has to be done ofcourse!).

Martin, did you order the door cylinders separately or was something delivered with the kit??

Thanks for the great construction photos!! Please keep them coming!! I'll be picking one up from Airworld USA shortly. I'm saving all the photos for later, I don't plan to start the build till next spring. I'm just starting construction on the 1/5 Saab Draken now.

Martin, do you have any pics of your airbrake setup - servo linkage, hinging etc.?? Going to attack the beautiful fuselage with a Dremel shortly...

Default RE: Airworld Gripen

the ducts are not part of the kit. I did it by my self. But the plugs for inlet duct and the 3 litres saddle tanks are now by Thomas Gleissner, may be he will makes molds and parts.

For the main gear door I've used Robart #165L Cylinder 3/8x2.5".
For the nose gear door, Robart #165S 3/8x1/2".
For airbreak BVM #5492 5/8x1 3/8".
The 5/8" cylinders are very slow moving because of the small connection. Maybe it's better to use the Robart #165 3/8x1" cylinder.

As you can see on following pictures I use 6/4mm diameter tubing for the hydraulic lines to the main cylinders, only the last part from the Y connector is 4/2.5mm.
For the 3/8" cylinders I use 3/1.5 tubing.
As hydraulic fluid use HLP ISO 22 grade. With 32 grade you will have to wait until gear is up.

About speed brake:
on my first flight I hade a leak in the hydraulic line to the brake cylinder because of the heat in the rear fuselage.
I lost pressure imediatly and i had a unwanted smoke system. It was luck, that i had the gear still in extended position and did a save landing.
Since then I have a full ducting from the main gear bulkhead to the rear, so the engine has no chance to suck hot air from the back. The hydraulic lines are replaced and filled, but not connected to the main circuit. I'll reconnect them when feel save about this lines.

Enclosed are also some drawings of custom made hinges and parts

Thank You, great info!

I was thinking of using JR8411s for airbrakes keeping the hydraulic system a little bit simpler.

Sorry I missed your previous request.
As you see Martin has worked his way through the problems.
One thing needs checking is Martin made his own fuel tank, so it's worth checking that the AW tank does not get in the way of any thing Martin has produced.
I also looked at Servos and air for the airbrakes, rather than more hydraulic lines.
I decided on a separate air system just to drive the airbrakes, though the Gripen is in my garage waiting for some spare building time.
I will also use a big JetCat turbine.

Great video...Now we see why Lewis Hamilton is moving to Switzerland!
