Precision Aerobatics Ultimate AMR 60 ARF, Yellow / Chrome

Words from Shaun, the designer and PA chief engineer

AMR 60 was designed in mind as a competition class bi-plane and NOT a park flyer. Built strong and precise with high technology engineering, the result being THE lightest bi-plane ever made in mass production. The flight envelope is incredibly wide from high speed super energy aerobatics to crawling super solid harriers and landings. That allows ANY pilot to confidently fly and enjoy the AMR 60, regardless of their piloting skills. The AMR 60 simply breaks the known barrier most biplanes earned for their high-speed landing and rapid stalls. No time or money was spared in the process of the design to the production. I was extremely picky while selecting every tiny bit whether it was a small nut or bolt, to the hinges of which we tested six different materials to get the best stiffness.

I had a lot of challenges during the design which made it my toughest project to date. The battery compartment and the ease of installing and removing the batteries was one. Also the hatch design and ease of installation. The quick installation system for the wing was a big challenge. There’s a lot of difficulty in the production process which makes this plane extremely expensive to produce at the high level we set. The result is an exceedingly enjoyable plane to assemble, transport and fly.

The extremely detailed and user-friendly manual took hundreds of hours to complete but the idea is to allow ANYONE to assemble the plane with ease.

AMR60 can be flown as an excellent sport plane, IMAC practice plane or the most energetic extreme 3D plane. All you need to do is to set up high and low rates (preferably three rate switches). Its large size and vibrant colour scheme allow excellent visibility and orientation in flight. I find it one of the most graceful aerobatic planes to fly, even if you just perform basic aerobatics like rolls and loops. It’s super smooth and precise.

I designed the AMR 60 from the ground up ignoring the full-scale Ultimate aerodynamic design, however, at the same time I did a HUGE amount of research on all versions of the Ultimate ever made and took every tiny bit I liked along with my own lines and combined them into a fine looking, highly modified Ultimate. By looking at it, it feels like an Ultimate, however, it is far from being scale. It exhibits no KE coupling and extreme maneuverability with unprecedented stall characteristics which will allow the pilot to perform every maneuver they can come up with.

Due to the challenges of the design and the targets we wanted to achieve, this project development and design spanned over more than 5 years. We went back and forth to the drawing board with new ideas refining the design each time to complete this model which is a real engineering achievement.

To name just some of the targets:

• Just a few minutes to assemble at the field, which are easily transportable even in a small car – Shaun developed the IWRS (innovative wing removal system) which requires only two bolts for the bottom wing, and two carbon retaining pins for the top wing.

• Unbelievably low flying weight for optimal wing loading and flight performance. The AMR 60’s weight all-up is about half of competing brands which makes it the lightest bi-plane ever made.

• Built extremely accurately with pre-set wing incidence (done twice, before and after the covering process). Wings and CF tabs are preinstalled in the factory to ensure excellent alignment and fit. All you need to do is bolt on the wings.

• Unmatched flying characteristics – no gyro is needed!!

• Simple and efficient control surfaces set up using only 4 powerful, yet economical servos.

• A new airfoil was specifically designed, tested and refined for this airframe to achieve the performance target.

• The unique aileron design enhances aerodynamic airflow and control efficiency, complimented by the optional carbon fibre Vortex generators.

• Wing carry jigs and a deflection metre included with the kit.

• Top quality unique wing bags specifically designed for the AMR 60. 

Assembly

It was our target that the assembly would be easy for the modeller and require only a few evenings.

• The instruction manual is the most detailed you’ll find and takes you step by step with high-quality large images and attention to detail that simplify the process (for example - CG set up by inserting a fishing line through a designated hole in the cabane struts – no measuring required).

• No pull-pull on the rudder, we were able to accomplish having the rudder servo on the tail with a direct drive, special oversized carbon fibre pushrod, to provide maximum strength and zero flex for best flight performance.

• The ailerons are already pre-hinged with the gaps sealed and as such assembling the wing is quick and easy.

• Elevator/stabiliser hinge slots are pre-cut and ready for you to glue the hinges.

SET UP

• Unlike others we don’t offer our team pilots superior gear and sell you cheaper stuff – what you see in our flying videos is what you get!

• Truly powerful set-up: 

  We raised the bar once again making the lightest and most powerful motor in its class! the Thrust 60 Revo 24 poles with the latest generation RotorKool® system making it lighter than our Thrust 50 yet even more powerful and cool! This motor is so efficient it allows us to power the model with 3s 2200 or 2600mAh packs or a single PA 6s 2600 mAh 22.2v battery. We chose to use 2 x 3S packs to allow these packs to be used in our smaller models. The 3s 2200 / 2600 is also a pack that is already owned by most of our customers so investment in a single 6S pack is not needed.

• This plane/gear combination is incredibly versatile, with the use of 3 different props, you can completely transform the plane, VOX15x8 for all-around freestyle performance, VOX15x10 for extreme high-energy aerobatics, and VOX16x7 for all-out low and slow 3D.

• We developed the new NXT-200 High Voltage (HV) servos and with them the new Quantum 80 EVO HV ESC with powerful (8amp peak) selectable voltage SBEC, which allows you to choose between 6v, 7.4v and 8.0v! These powerful servos are significantly lighter yet offer more torque, and a smaller footprint taking its performance to the next level! The NXT-200HV will beat ANY other servo brand in value for money, hands down!

• Easily accessible battery tray, a common issue with bipes – but not in this one!

Construction and hardware

• FiberFusion® engineering at its best, exploiting knowledge from the past 14 years, utilizing the strengths of the fibres within each raw material, with the end result being lighter, stronger, more rigid aircraft that fly like nothing else! No black spraying of components just to trick the eye! No cheap lamination that you’ll now see in so many RC models. There is a LOT of construction engineering and testing work done on each part of the plane.

• No compromise on smooth flight performance, we sourced the hardware from multiple suppliers worldwide. The ball links and couplers from Germany, selected quality anodized socket head cap screws throughout, making the assembly a breeze. * Top quality high-temperature Carbon fibre components are all made in-house: from the carbon fibre CNC machined control horns and cabane struts to the landing gear and spinner cone. Carbon fibre wing tubes and pushrods as well as the many reinforcements and formers in the structure are all made of the real stuff! Even our T60R motor X mount is made of CNC machined thick solid carbon fibre plate for extreme rigidity and significant weight reduction.

• The AMR 60 is built using the finest grade material, all cut by state-of-the-art laser and CNC machines and pre-assembled by our skilled PA-owned factory staff. Competition-grade balsa is selected to ensure consistent quality and density through the entire airframe in each and every airframe. This means no wavy balsa sheeting and full control over the model weight.

• To attain uniform performance for each and every model produced, we build the planes on very precise jigs. Each set of wings is matched individually to each fuselage (this is something most factories don’t do even in giant-scale production).

• Metal hatch latch

Flying

• No bad flying tendency – This is a one-of-a-kind biplane on the market capable of flying as well as a monoplane and yet offers the unique cool biplane experience and unbeatable stunning in-flight appearance. It also makes a cool wing whistle during high-speed passes and KE!

• It tracks like it’s on rails, high-speed knife edge circles, superb precision, incredible high energy maneuvers (crankshafts, pop tops, blenders, this plane loves it all), graceful walking speed low and slow 3D, harriers with no wing rock in any position, super rolling harriers, hovers and torque rolls, this plane does it all! It’s up to you to set the pace.

• The AMR 60 has a quick, crisp response at high rates and will lock into KE at any speed or angle of attack. It’s an excellent tumbling machine able to execute tight spins, violent snaps and crazy waterfalls. Its fast axial roll is provided by four huge ailerons coupled with rigid Fiberfusion® airframe construction.

• Low rates tame the AMR 60’s personality to smooth and precise. Perfect for precision IMAC or sports-style flying. Long fast turns are very accurate and without adverse yaw or loss of attitude and beautiful straight lines. Four-point rolls and eight-point rolls are simply beautiful.

• Worried about landing? Forget what you have heard about biplanes. The AMR 60 is THE easiest biplane to land. It will practically land itself at any speed without the risk of wing stall. It’s a breeze to perform perfect landings without the need for a fast approach and a long runway.

• With such a wide flight envelope, whether you are after sport flying, precision or extreme 3D/freestyle this plane is for you!
