It looks like a Raptor with some head parts from the Sceadu and some other custom metal parts.

EVO Ripoff?

Might want to take a closer look at it. The only thing EVO on it is the canopy. I think?

Metal and plastic head blocks, flybar carrier, main blade grips, paddles, swashplate plus the hex start adapter all look similar to Sceadu parts. Main frames look like a Raptor.

This is just a Raptor 50V2 with a modified Hirobo head and a Hirobo canopy.
gotta laugh at it ! My guess is that these guys found the OEM manufacturer of Hirobo and TT...

Hi guys

Thanks for your interest in Precision Aerobatics.
At the moment we have two helis available: Challenge 50-glow heli and
Thunderbird- an upgraded electric heli.
We are international company (ship worldwide) and most of our products are manufactured especially for us (per our own designs and modifications..) so the Challenge 50 is not an exact copy of any heli. However this heli combines some plus points the factory found on other models with new designed parts.
We also provide parts & accessories for our products.

You are all welcome to visit our website at http://www.precisionaerobatics.com

Definate EVO canopy. The head and other stuff doesn't look EVO.

Looks like a solution for those people who can't decide between a Raptor or an Evo.

Must be a coincident that their model looked like a Raptorchassi, with EVO head (kind of) and Sceadu canopy...

What is the infringement really?

What's to stop any of us doing the same thing. Does that mean we'd be infringing or being inventive?

Just for argument's sake, Jason Krause and Todd Bennett have announced they are in the process of developing an all-out 3D heli called the "Synergy".

Surveying the current crop of commercially available helicopters -- especially the 50 size, and 60/90 kits -- how much difference is there between the popular ones when it comes to the mechanical design?

What will the reaction be if the Synergy is introduced and it just looks like someone else's heli from a short distance? There are great expectations, and most likely, the final product will disappoint many simply because it looks like any other pod-and-boom chopper already on the market.

There has been a very little innovation in basic helicopter mechanical design since Dieter Schluter came up with his "beller" (Bell/Hiller) designs in the 1970s. Most of the innovation since then has simply been refinement of the basic layout. eCCPM mixing has arrived simply due to the evolution of radio electronics.

At this point, there are only so many ways to control the swashplate, rotor head, and tail rotor system. It would be extremely difficult at this point to actually come up with a unique, never been produced before heli basic mechanical design. To date, everything that has been produced has only been a variation on the Schluter basic design, and manufacturers have been able to leverage new materials (plastics and carbon fiber) to improve on that basic design. Rotor blade design has improved due to the use of CF and fiberglass. Engines have improved greatly. The heli is still based on the Schluter floorplan.

The only thing left to really differentiate one heli from another these days is the aesthetics -- what it looks like. And frankly, a pod and boom is a pod and boom. At least the Raptor and Caliber 30 -- both fine helis -- took the road less traveled and developed a real butt-ugly canopy to differentiate themselves from the rest of the pod-and-boom crowd. (Well, the Caliber does also have a very innovative belt-driven drive train, too).

So what if it looks like a cross between a Raptor and an EVO. The proof will be how well it flies, how well it is supported, and how well it holds together.

i see nothing wrong with bringing what a lot of people might consider the best of a few different brands.

Strength of the Raptor frames
The tail gear box of JR (I think)
A metal CNC head of some brand.

Personally I'm not much for the Sceadu canopy.

If it flys well it will sell. It's going to take someone to give it a whirl though.

Challenge 50 review / Airborne magazine

Advertised on Nov 2004 Airborne mag by Trent Collins

Immediately after laying eyes on the Challenge 50 for the first time I knew this was going to be a great machine. The metal head block, metal auto hub and metal pitch arm showed that this machine meant business straight out of the box. After a quick inspection over the Challenge 50 I was very impressed with the level of ‘standard’ parts that came with the ARF package deal. The fibreglass canopy and carbon fibre blades put the Challenge into a class of its own when it comes to 50 size ARF models. No other kit comes with these as standard which shows the value for money aspect of the Challenge 50. With a metal head block, there was no flex in the head which meant there would be no flutter during hard 3D manoeuvres and the Challenge would have a rock solid hover. The metal pitch arm again reduces flex to ensure better pitch response during flight. As standard, the Challenge 50 comes with a metal auto hub unlike many other 50 size machines which come with a 1 way gear. With all these standard features I didn’t expect to need any upgrades at all.

After a quick check over Challenge 50 to ensure the radio setup and control linkages were ready for flight a normal and 3D flight modes were programmed into the transmitter. Radio gear used included 4 x JR DS811 servos, a JR R600 receiver, a JR X378 transmitter and a Futaba GY401 with S9253 tail servo. The pitch ranges chosen were -5, 6, 9 for normal mode and -10,-6,0,6,10 for 3D flight. Achieving a 20 degrees pitch range on the Challenge 50 was surprisingly easy. The Challenge 50 has a total pitch range of approx 30 degrees without any binding in the head, making 3D pitch curve setups a breeze. For the test flight, approx 50% travel was used on cyclic controls and the GY401 was setup as per the norm. I also setup the throttle hold curve to be the same as the 3D curve so I could test the carbon blades with some autos.

In typical O.S. fashion, the OS 50SXH started first time and settled into a sweet idle. Spooling up slowly just to check everything was ok, showed plenty of smoke coming form the OS50 and after a quick control check the Challenge was lifted off into a steady hover. With the blades perfectly in track, the hover was rock solid and I felt comfortable straight away. The GY401 was working perfectly with the Challenge 50 tail setup and it was quite easy to hover “hands off” facing any direction. Hovering side on showed the nice lines of the fibreglass canopy and after a few tanks of hovering it was time to expand the flight envelope.

Starting with some short climbs and returns to check the engine tune and low end pickup I headed out on some circuits. The first thing I noticed was the steadiness of the model in the air, It felt and looked more like a 60 size machine than a 50 sized machine. Control response was smooth and precise, and with a small amount of exponential on the cyclic the Challenge was very nice to fly. Some high speed circuits showed the ability to retain speed and I expect the Challenge to perform quite well at F3C type manoeuvres. Some hovering for photos followed by a complete check of the control linkages at the conclusion of the flight to ensure everything was still tight was carried out.

Next up it was time to check the 3D performance. At a safe height the 3D flight mode was selected and after some small adjustments to the pitch and throttle curves the Challenge 50 was ready to roll. With the carbon blades and the standard paddles the Challenge took everything I could throw at it. I can honestly say that I love the standard paddles that come with the Challenge. The rolls were perfectly axial with no engine bogging. It was quite easy to string together 20 plus rolls without loosing head speed. Inverted hover was solid as a rock and could be entered by either flipping or rolling into place. Over subsequent flights the Challenge showed is ability to perform more complex manoeuvres like death spirals, tic tocs and tornadoes. With the carbon blades and the OS 50 on full song, the Challenge has plenty of pull, and a lot of torque to get through those pitch intensive manoeuvres.

Next it was time to check the Challenge in an auto. Wow those blades really carry some energy. It was quite easy to auto down, pull back on cyclic to stop forward movement in front of the pilots box, feed in some pitch to climb a little, spin the tail around 180 degrees and set her down gently. It’s not very often that you can do that with a 50 size machine.

What impresses me the most is that the guys at Precision Aerobatics are open to suggestions and recommendations to design modifications and improvements. This is really the only helicopter on the market where you can request design/hardware changes and be told straight away if your recommendation is being utilized on the next production run. Precision Aerobatics are also carrying a full range of spares to compliment the Challenge 50, and more importantly the spare parts are reasonably priced.

As a comparison, currently I fly a highly modified Raptor 50. I have installed a full metal head, am currently using white Fury paddles amongst a myriad of other upgrades, all of which have cost me a small fortune. I have my cyclic movement set to max deflection, just before it binds. On the Challenge I had the standard paddles and approx 50% swash movement and I much preferred the flight performance of the Challenge 50. The Challenge feels very stable, more stable than my raptor. It runs super smooth and I am very impressed with its 3D performance. The combination of the paddles and head that come standard on the Challenge really produces a remarkable machine.

Subsequent weekends have shown that the Challenge 50 has hit the market as one of the new mid sized powerful models that you can take out for a gently fly around, or a good old fashioned thrashing. Is it often difficult to some up a model as most people have already decided on which helicopter/brand is for them. Still, here’s my own thoughts. The value for money that the Challenge offers is second to none out of any deal currently available on the market. All that metal is both very functional and also provides that “bling bling” appeal we are always after. The fibreglass canopy and carbon blades really set this model apart from the rest, and as far as the flying performance goes, it will do anything straight out of the box and most importantly doesn’t need any upgrades.

The Challenge 50 is definitely worth a second look whether you’re a learner or an experienced flyer alike.

Hi guys,

Just follow the link above and take a look, i think it's the completely same mechanics just with an evo 50 canopy on it.

Best regards,
Gio.
