This is one smooth and beautiful airplane! And with a big enough wing area it should have a wide speed envelope too!

Status: Ready for maiden flight!

I present you the prototype of the ARGUS.

​

A 45mm spinner fits perfectly and completes the scale look!

Here are the GENERAL SPECIFICATIONS:

• WINGSPAN: 1100 mm | 43.31 in
• DRY WEIGHT: 502 g | 17.71 oz
• ALL UP WEIGHT: 644 g | 22.72 oz (with 1300 mAh 4s)
• CHANNELS: 4 (THR | AIL | ELV | RUD)

The ARGUS is a mixture of classic and modern FT building techniques. It uses the FT Mini Power Pod. The scaled ARGUS has a very short landing gear – it is a „low rider“ and for this scale look, you should use a 7" propeller with a 1400 kv 2212 brushless motor. The wheels have a diameter of 45mm (1.75 in). Of course you can build them yourself with the templates in the plan.

For the maiden flight I will use the following SETUP:

• MOTOR: 1400 kv (2212 Sunny Sky)
• PROPELLER: 7 x 6
• ESC: 30 A
• SERVOS: 4 x 9 g
• BATTERY: 1300 mAh 4s (Turnigy nano-tech)

The ARGUS works with the FT POWER PACK B. I will also add longer landing gear parts to the plan for using an 8" propeller and the FT Power-Pack B motor on 4s with the landing gear. If you don't want a landing gear, you can also build it as a belly lander.

WOW!!

Everything was quiet, and then BANG! What a beautiful build! Very nicely done!

Excited to see how she performs, and how the landing gear pylons work out - that's a neat approach!

 

[whackflyer]

That is one beautiful aircraft! Can't wait to see the maiden...

 

[TooJung2Die]

That is a very well executed balsa to foam board conversion. Starting with a control-line design makes it extra challenging. If it flies one tenth as good as it looks it should fly great. Nicely done.

 

[SP0NZ]

Amazing! As usual.

 

[JClaude]

Wahouw, it's beautifull.

 

[skymaster]

awesome love your builds

 

[cdfigueredo]

Incredible building, very well done. I had been wondering if a CL to RC conversion would work, and I think I'll get the answer soon. Waiting for the maiden flight.

 

[AircPirateNinsei]

Unfortunately the maiden flight was not successful! It took off well and then it turned right and dived the nose.

Then it hit the ground - too bad!

The brushless motor is undamaged! The spinner intercepted the impact. The battery is crushed.
The heat shrink tube of the ESC is torn, but it is still working correctly.

Now I build a new Argus out of my last four FT Foamboard sheets. I will change a few things on version 0.2, so stay tuned.
There is still some time until 31 January 2020.

@flitetest : Please send FT Foamboard to Graupner Germany! It's sold out!

Dam, it was looking so good!!!
Can;t belive that.
Don;t dissapoint, make a new one and try it again, we will be all waiting.

 

[TooJung2Die]

Thanks for the the first flight report. It's only a failure if you don't learn something. That type of crash right after launch is consistent with having the ailerons reversed. Guess how I know?

She was so sleek and beautiful! What do you think the cause of the crash was?

 

[AircPirateNinsei]

I think the rudder deflections were way too small. I was a bit too shy with the first acro. It's a shame, but it doesn't matter, because you learn from every mistake and hope to make it only once.

 

[AircPirateNinsei]

V0.2 of the Argus is ready for maiden:

It has a full acro wing, air outlets, an enlarged battery hatch and the landing gear is reinforced with BBQ-Skewers. Mounted is an Emax mt2213 kv 935 (compatible with FT Power Pack B) and an 8" propeller. The wingspan is 1100 mm (43.31 in) and the AUW with a 4s 1600mAh is 667g (23.53 oz).

 

[Grifflyer]

Looks great!

 

[cdfigueredo]

Waiting for maiden results... Looking excellent

 

[TooJung2Die]

That's a beautiful airplane.
