Designed for 700/800-class models like the Pantera P6e and P7e, as well as T-Rex and Goblin 700, plus various 800-class models. Depending on the battery pack, this motor is well suited for scale, sport, hot-sport, and extreme-3D maneuvers. Capable of generating 4500W (about 6 hp on tap), there's sufficient power reserves for pretty much any maneuver you can think of.
This brushless 4500W motor is the maximum size, which will fit in a Pantera P6e, either the standard model or a Stage II
- 6S ~1200 RPM (scale 4-blade head)
- 8S ~1550 RPM (scale, 2 or 4-blade head)
- 10S ~1950 RPM (sport, mild-3D)
- 12S ~2300 RPM (extreme-3D)
- Poles = 10
- Slots = 12
- Winding = Delta
- Operating temperature = <260°F
- Maximum temperature = <350°F
Use care when mounting so the screw threads of the four M4 bolts (30mm mounting pattern) don't protrude beyond the stator and into the windings, which may damage them. You've been warned.
- PDRM5858-540 motor dimensions and layout
Basically the largest diameter motor you can comfortably stuff into a Pantera, this 800-class motor is referred to internally as Pmax. Ideal when matched to the Pantera airframe, this is ProModeler's top-of-the-range motor. And you'll love it too because it can almost be thought of as dial-a-motor. E.g. dial the power up or down via the number of cells.
Basically, dial it in for sport aerobatics - like loops, rolls, and stall turns, plus flips and tumbles - by using an 8S LiPo pack. This gives you plenty of power - the approximate equivalent to an OS 55-class nitro engine. With this much power, you can also effortlessly cruise around - for up to 12 minutes on a 5000mAh pack, which is plenty of air time. This combination is great fun too because you get sweet performance at an affordable cost. This is because 8S packs are modestly priced and as an added benefit, these packs can be charged and cycled with relatively inexpensive chargers.
Alternatively, in the Pantera you can dial it up by using a 4400mAh 10S battery pack. Now you'll get 9-10 minutes of rock and roll because the motor RPMs increase with higher voltage as the stunningly simple system of varying output delivers a surge of raw horsepower. How much? It's enough for any 3D maneuver you can think of because you're getting horsepower rivaling 91-class nitro engines. In fact, it will easily exceed the output of any nitro-engine available - no matter the cost. Now you can power through tick-tocks, rainbows, and any other power-hungry maneuver you can think of. Heck, you'll be able to do tick-tocks while climbing - with the reserves of power, which permit you to overcome mistakes without missing a beat. This may be the perfect combo for learning 3D because you'll have the horsepower to save things - before you blow the maneuver - while using moderately priced packs.
However, it gets better because if you stretch your Pantera to a 700-class, you get astonishing performance by dialing things up another notch via the simple expedient of using a 12S pack. Yes, more voltage means one of two things. Either going for uber-intense 4-1/2 to 5 minute flights while using lightweight 3350mAh cells, or significantly longer flights with bigger packs, the larger rotor disk handles the weight with ease because of a reduced disk loading compared to 600mm blades. And if it's a Pantera, you benefit by reusing all your expensive components because a stretched version is still the same basic machine, e.g. the same crash costs and the same friendly handling because all you did was opt for a stretch conversion with more power.
In fact, there are lots of benefits from running 700mm blades and a lower disk loading is one of them. Either way, a 12S set up offers intense hold-onto-your-socks performance. Moreover, the still higher RPMS means you'll get the cyclic quickness of a 450-class heli - but in a much bigger package. The fun is utterly sublime too because it's an honest giggle-maker. Best of all, it's fun with an inexpensive model. One, which is big enough to let you basically ignore the wind. At last, the freedom you've dreamed of without the complication and big ticket expense of other models. Simple really is best!
However, for the ultimate in power, figure on using the PDRM0800 with a 14S pack. When your model is dialed up to the max, the power output beggars the imagination. Awesome inadequately describes the resulting performance because you and your Pantera are capable of performing any maneuver within the bounds of imagination. Whether using 600mm blades, or if you've stretched your model, while using 700mm blades, you'll astound everyone with towering climb outs. And once you race your pals and blown them into the weeds in a drag race you'll get a face stretching smile that will last for days! Thus, even if you're just learning, beginners can enjoy the rush too . . . because the power is delivered effortlessly - without any tuning complications of a nitro engine and fuel. This is real serious fun.
- Pmax - this is the largest diameter motor, which can be comfortably stuffed into a Pantera
And the power will last too because unlike motors using an 8mm diameter foundation, the Pmax features a 10mm diameter motor-shaft (yeah, like many 600-class helicopter main shaft bearings). Moreover, at just over 100mm in length, this massive stainless steel shaft forms the basis of an 800-class outrunner electric motor, which you can stuff into a 700 -class model (and big 600-class models like the Pantera family) without breaking the bank. Moreover, the rotor features 10 Neodymium magnets radially arrayed within the body. And these strongest of rare earth (NdFeB) magnets are secured with high temperature epoxy because pilots flying the Pmax are prone to flying it hard - like they stole it. Thus, high temp epoxy is how you can be assured of handing the power without slinging a magnet.
Designed and manufactured to the highest quality standard, the greatest care has also been expended in making this monster run smoothly because it's been dynamically balanced - at 25K RPM. This is the purpose of the blue epoxy weight material. All this care ensures a seamless and smooth power delivery. One, which won't buzz your electronics to death with vibration. Big, bad ass, and smooth as silk . . . it's a nice combination at the heart of your power system.
- Massive 10mm shaft - rotor is dynamically balanced (blue epoxy) to 30K RPM for silky smoothness
With a low resistance of 0.012Ω, the Delta-wound motor has 6-turns. Moreover, bigger 10mm bearings (as compared to an 8mm motor-shaft design - with all the attendant nonsense of requiring multi-bearing stacks of 3 bearings to support the off end of the rotor in a frantic attempt to support the loads) basically means the frequent bearing maintenance you became used to with popular 4035 motors becomes a thing of the past. At last, serious engineering versus marketing BS gives you a heavy duty motor for heavy duty flying while respecting your wallet. Simply put, installing a Pmax in your model means flying without worry about tiny bearings, e,g, them getting rough and worse, if you don't notice in time, having them fail (with the risk of dragging the rotor into the magnets and thus ruining the motor).
- 6-turn stator features massive bearings - big like those supporting the mainshaft of many 600-class helis
Bigger bearings, bigger shaft, bigger motor equals the bad ass Pmax for powering your Pantera, or other 7/800-class models - it's perfect for powering the rush.
