If you demand high performance precision flying, high energy 3D/freestyle aerobatics, extremely light and rigid Biplane, the Ultimate AMR is the machine of choice for you.

Forget what you have heard about bipes..Hard to handle? Stalls easily? a handful to land? well CERTAINLY NOT WITH THIS ONE. Many months of design, testing and experimentation brought about this exceptional model.

The new Ultimate AMR features the revolutionary FiberFusion® construction making it the lightest electric built up Biplane produced to date in this size – about 38.45oz ready to fly (!!!) yet is rigid enough to withstand the most extreme high energy maneuvers we know you will be tempted to try!

FiberFusion® is an engineered construction method, combining carbon fiber, balsa and ply in a way never seen before, utilizing the strengths of the fibers within each raw material, with the end result being lighter, stronger, more rigid aircraft that fly like nothing else!

The Ultimate AMR is easily transportable and will fit in any backseat of a car without the hassle of removing the wings. The wings are still removable for convenience of storage if desired.

Many months of testing and experimentation led to the design of a new airfoil specifically created for this airframe in order to achieve the pre-determined performance we had set. The unique aileron design enhances aerodynamic airflow and control efficiency. To complement the Ultimate AMR performance and CG – we had to design a new brushless motor the PA Thrust 40. The combination of the AMR unique design, exclusively designed airfoil, and our new Thrust 40 motor gives the feel of flying on a 4S pack with unlimited vertical performance although it is only using 3S 2200mAh 20c Lipo pack, without making any compromises on any maneuver or on flight duration and without having to make a costly investment in expensive battery packs essential on other heavier biplanes!

The PA Ultimate AMR is built using finest grade material, all cut by state-of-the-art laser and CNC machines and pre-assembled by our own skilled factory staff. In order to attain uniform performance for each and every model produced, we produce the planes on highly precise jigs. Each set of wings are matched individually to each fuselage (this is something most factories don’t do even in giant scales production).
We assemble each airframe before shipping to ensure wing incidence, alignment and fit. All you need to do is bolt on the wings. The ailerons (as well as the stab/elevators) are already pre-hinged with the gaps sealed and as such assembling the wing is quick and easy.
We have thoroughly researched full size Ultimate versions as well as experimental modified aircraft and although you will not find a similar full size Ultimate, the PA Ultimate AMR is an extremely scale looking Ultimate with a unique PA touch.

Although the Ultimate AMR looks stunning on the ground, its performance in the air will be the one that will simply blow your mind. From quick paced high energy, jaw dropping aerobatics all the way down to slow graceful 3D, the AMR does it all and it really up to you to set the pace.

On high rates, the handling is crisp and lightning quick response. It will lock in Knife Edge at any angle of attack and at any speed. Both upright and inverted harriers (a disability in many other bipes) are stable and rock-free while the hovers are vertical and easy to control. Torque rolls are simply beautiful to watch and the 4 huge ailerons provide adequate authority to torque in the opposite direction on demand. As for the flat spins:- How’s flat for you?
On high rates the PA Ultimate AMR is an excellent tumbling machine able to perform extremely tight waterfalls, spins, violent snaps etc that is would make it a hot pilot’s dream come true. The lightning fast axial roll rate provided by the 4 huge ailerons coupled with the rigid construction of the airframe give the Ultimate AMR the ability to execute violent axial Knife edge spins, high speed blenders, lomcevaks and insane tumbles that will bring your excitement to a whole new level.

Although the Ultimate AMR is an unlimited 3D/Freestyle beast, switching the dual rates onto low rates sets it’s personality to smooth, precision IMAC or sports style flying you would get the distinct impression that it’s flying on rails. Rolls are axial, well balanced and could be easily performed slow and persistent. 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 of landing? Forget what you have heard before about bipes. The PA Ultimate AMR is probably the easiest biplane to land. It practically lands itself at any speed without the risk of wing stall. It is easy to grease a landing without the need for speed or long runways. You can even land during a harrier.

In the words of the Ultimate AMR designer: This plane will challenge you and allow you to perform many new maneuvers that other planes just don’t allow. It’s you getting used to the plane, squeezing the juice out of it that makes it so exciting.

In line with PA’s tradition, this fine model spells QUALITY from the design to the construction, the hardware and the level of finish - the attention to detail is second to none.

Available in three striking colors the Ultimate AMR looks simply awesome in the sky. The two wings allow easy orientation in flight.

This plane is nearly complete and has very little left for you to do:

Wings and ailerons are pre-hinged and sealed!
CA hinges already pre-glued on the rudder side.
Horizontal stabilizer with the elevator pre-hinged and sealed.
Fiberglass cowling is pre cut and is reinforced with carbon fiber. Its aerodynamic design allows air to flow in and cool the motor, battery and ESC for maximum setup efficiency. Two air scoops are also included in the kit.
Prefabricated and pre-painted tinted canopy and hatch as one integral unit attached to the model with very strong magnets.
Pre-drilled stiff CF landing gear and pre-installed blind nuts in the fuselage for quick installation.
Pre assembled motor box with the correct thrust line already built in (taking away the guess work).
Pre-drilled FiberFusion® firewall is ready for Thrust 40 outrunner installation.
Pre-cut fiberglass pre-painted wheel pants (optional carbon wheel pants are available)
Semi-fabricated heavy duty Carbon fiber push rods.
Pre-drilled Carbon fiber control horns.
Pre-installed battery and RX Velcro fasteners.
Pre-assembled tail wheel.

The brief assembly is a joy and most modellers will have it set up in one evening in-spite of the two wings! We have also included a deflection gauge to ensure precise control deflection is easily achieved to attain the designed handling characteristics.

Couldn't find the cost of shipping. Any idea how much to 100 south of chicago?

aerofundan

Not sure about shipping price, but if there is any it shouldn't be much since its shipping directly from USA.

That's cool. I was wondering where it was coming from.

reyn3545

I just finished building mine.. will maiden tomorrow.

At this point, the only thing I don't like is the canopy/battery access. I had to cut one of the formers off at the top to get clear access to the battery tray for installation. Also, getting the canopy on/off is a bit of an exercise in contortion.

I have the Extra 260 and love it. If this plane flies anything like the Extra, I'll learn to live with a little inconvenience on the canopy.

mrbigg

My Feedback: (21)

What color did you get?

reyn3545

I got the red and black.

Got the maiden flights in today... overall, a very good flying bipe. It takes off and lands very smoothly, holds a hover and harriers well, like a good bipe should. There's a little more coupling in knife edges than PA would lead you to believe, but again... it is a bipe.

I went with the stock config, purchased everything from PA. Plenty of power and motor, flights are in the 10 minute range with moderate throttle management.

PA does mention in the instructions, and there is one little quirk you must get used to.....

When properly trimmed, the plane will naturally climb at about 1/2 throttle. This is due to the wing configuration. If you trim that out with elevator, then it will want to dive at slower speeds. The wierd part is that when inverted, you would normally put a little nose pressure on the elevators... but with this plane, you have to pull back just a little. Very strange, but you adjust to it pretty quick.

There are 2 things I'm not crazy about...

Canopy - as I mentioned earlier, you have to twist it around a bit to get it on/off, and I had to cut one of the fuse formers to make it easier to get a battery in and out of the plane.

Tailwheel - I don't know if its the wheel or the rudder wood that it's going into, but I haven't been able to glue the tailwheel in and make it work. It constantly falls over to the side. I've glued it in 3 times so far, and at the field today, it was all but useless. Fortunately, you don't use the tailwheel too much. I've re-glued it again and we'll see now it works. If it doesn't work this time, I'll just go with a metal dragging bar instead of the wheel. No big problem. the PA Extra has almost the exact same tailwheel setup, I glued it in once and haven't had to touch it since then. But this one, for some reason, is giving me fits.

All in all, a good flying plane. I like the way the extra flies a little better than the bipe, but for a bipe, it's a pretty fun plane to fly.

reyn3545,

Thanks for your review. As you gain more flight time with it, please post more. I am thinking about something like this but have not made up my mind yet.

Thanks again.

Electric planes and me have a historically short relationship... They are so easy and fun to fly near the ground, its usually not long until the ground jumps up and reclaims the balsa.

But... to PA's credit... I cartwheeled my PA Extra a few weeks ago, and the left wing crushed most of the left side of the fuse in the mishap. I just assumed the plane was trash, and I wanted an electric bipe, so I bought the Ultimate.

While I was working on the Ultimate, I decided to take a good look at the Extra. Most of the wood was missing from one side of the fuse, the canopy was completely trashed (prop ate it), gear was knocked out, but the wings, motor box, cowl, etc... looked in good shape. So, I went to the local hobby shop, bought a new canopy and some balsa. After about an hour, and without even peeling any covering off, I was ready to fly again. I took both the Ultimate and the Extra to the field today. The Extra flew every bit as good as it did when it was new! Dead solid elevators, harriers, knive edges, a great flying plane.. even with a few blemishes.

I don't expect a biplane to be quite as lucky in a tumble, so I'll try to respect that and keep it higher for a while.

That's freaky and kind of a turnoff. Seems like the incidences are off or the down thrust is off. I'd redo the down thrust first as it is easier to adjust. I can't believe they would design this plane like that. Weird.

today was unusually warm and calm for January, so I wen to the field again.. still working with CG and KE mixing... its getting better.

aerofundan

It sounds like your plane is tail heavy, talking seriously i was flying a lot of precision flying on my ultimate last week and i didn't experience any change in trim, it flys precision like its on rails.

I recommend you guys give a check to the RCG post for the Ultimate, A LOT of people there

Just maidened mine today, beautiful weather, snow still on the ground except for a few grass "islands" took off and landed on the same 6 foot island each time with the greatest of ease.


Love the plane, best rolling harrier in history, awesome torque rolls. best flatspin I have ever done. So graceful and predictable... So... AWESOME!

If you haven't yet you need to get your hands on one!

I can't say enough good things about the PA IPS pro package, it's just... perfect. Everything is cool, nothing is being pushed anywhere near their limit and power/ response of the Quantum 45 and T40 combo is just outstanding!



I devised a trick to help with the PA tail wheels, this works on all their electrics so far that use the T30 and 40; you dig a channel for the piano wire, drill it's hole for the 90 degree bent part at the end and then; you cut hinge slots on both side of the wire, both at the bent end where you drilled, then at the other end at the root of the tail gear (near leading edge of the bottom part of the rudder)

then you fold CA hinges and insert them in the slots you made, this acts as belts strapping the wire in, you want it nice and tight, and if you can get a bit of the hinge to overlap the 90" point that you drilled for, all the better as it will increase resistance to torsional forces (it is better to cut them shorter and smaller as otherwise the leading edge one and it's slot would meet up with the control horn; you don't want to go that deep)

You then proceed by wicking thin CA into the hinges and let it cure on it's own (no kicker) Finally, when this has cured I like to go over with medium or thick CA (I usually use foam safe as it's consistency is just perfect) and fill the rest of the groove.

Haven't had a tailwheel come out in 100's upon 100's of great, good and not so good PA landings.

Rhus

Hey guys,

Does anyone know the bolt pattern of the motor mount and/or the Trust 40? Can't find it on their site. I'm trying to figure out if my Scorpion 3020, with a 25 mm spacing will fit properly. On the Ultimate if I order one.

Thanks,

Daniel,

I have really enjoyed your videos and they have been a real inspiration to me in learning to fly 3D. Your flying abilties are just awesome! I don't yet own an Ultimate AMR but do have the Electric Shock (2), Addiction (5), Katana Mini (1) and Katana MD (2). I have owned quite a few brands and think that the PA planes are the most refined. I have found that using the standard PA setup tends to have excellent results so apparently most of the tinkering has already been done with these models. I was wondeing of the various PA planes which might be your personal favorite? Also, could you share any advice on trimming a Katana MD for 3D? I have been fiddling with the CG so that the plane flies level upright and inverted but I am not sure if that is optinum or not?

James

aerofundan

Hi James, i'm happy to hear you enjoyed the videos!, You will love the Ultimate AMR, to be honest every new PA plane coming out it gets better and better! About 3D Setup for the Katana MD, most important things, get as much throw as you can on the rudder and elevator, the optimal cg for 3D, is right between the spot you are right now, i do recommend not going too tail heavy or you could have problems when landing, and the plane will get unstable for precision flying, the spot i like is where it drops just a bit while inverted. I see that you in FL, I will be at this years SEFF which is in GA the last wek of april, there PA will be presenting a new airplane!

Daniel,

Thanks for answering my question about CG on the Katana MD, I will set it up as you suggested. As to your videos, wow how could anyone not enjoy them, your flying is awesome and it is really helpful to see what a plane is capable of.

I haven't yet ordered an AMR but will consider adding it to my bulging collection. I am curious about the new plane that is to be released, Shaun has been so secretive about it. I think that you made a good choice to represent PA, they really produce an excellent product.

Take care,

James

Has anyone used the E Flite 480 1020KV motor for this plane ?


I am not sure if it is enough motor for this bipe.


I run 3 cell 2200 packs with that motor and they are a good combo.


Thanks Scott

Jet_Plane

Rhus,

I've just stumbled across this thread so sorry for the late reply. Bolt centres are 25mm so the Scorpion should physically fit.I think your main problem will be weight. The Scorpion 3020 is about 170g (i have one) whereas the thrust 40 is 140g. You will end upnose heavy with the 3020 installed. The battery tray isn't long enough to allow enough adjustment to make up for an extra 30g in the nose.

The hacker A30-14L is a decent alternative to the Thrust 40. Same weigh and same power rating, a little lower kv on the Hacker but in practice i don't think there is a lot of difference in performance.

Steve

Jet_Plane

Scott,

That motor would be probably enough to fly the AMR as a sport model but if you want 3D performance your going to need something close to the Thrust 40 spec (500W, 140g, 850kv). I've tried the Hacker A30-14L which works great and also as a budget optionthe E-max GT 2820/07 which is ok but a little down on power compared to the Hacker.
