In 2012, after two years of development we were able to celebrate the launch of the Banshee 700 and the incorporation of our company. Today, almost four years later, the Banshee 700 is still one of the most uncompromising model helicopters on the market.

With two years of further development and almost four years of valuable customer feedbacks regarding the Banshee 700, we present you the next level of evolution, the Banshee 850. A mechanics, which is designed for rotor blades up to 850 mm. Our main development goal was to take the original Banshee to the next level without compromising our previous concept of a rugged, rigid, low-maintenance and lightweight mechanics with a unique sound characteristic.

This lead to an unchanged mechanical concept, which was improved and further refined in many aspects. Therefore, at first glance it might seem that much has stayed the same since we consciously proceeded with sensitiveness. We didn’t want to develop only a scaled mechanics; our intention was a load-dependent improvement. Thereby we were able to reduce the weight of some parts despite their higher load carrying capacity. We are really proud that this leads to a model helicopter with a mechanical weight of only 1.95 kg * which is able to withstand all loads in 3D or speed flying. Consequently, the Banshee 850 makes it easy to set up a take-off weight below 5 kg. 

The entire design, particularly the canopy, landing gear and the tail boom were adjusted to the new helicopter size, resulting in appropriate proportions while noticeable improving the visibility. The new canopy, with its beefy but elegant design still embodies the Banshee typical aerodynamic shape.

All this points are resulting in a complete new sense of flying. Due to the reduced rotor disc load, the Banshee 850 gives a very good locked-in feeling, while doing moves very powerful even at low rpms and low collective pitch. The performance at 1700 RPM and 12 ° collective is comparable with a 700 class helicopter at 16° collective and 2100 rpm. The performance at high rpm combined with high collective input has to be controlled very precise…

* Mechanics include all bolts, velco straps, canopy with applied decor and tail fin with applied decor.

General concept, designed for:

  • Drive power > 15 kW peak
  • Rotor blades up to 850 mm length
  • Motors like Pyro 850 or Scorpion 5035
  • Up to 16s lipo stick-packs
  • Big speed controllers like the Kontronik Kosmik 200 Cool


Gear innovations:

  • Bigger motor carrier for a better transmission of force to the mechanical core and a better heat conduction.
  • Wider motor belt drive with a new free-wheel pulley and new motor pulleys to withstand extreme loads.
  • Motor belt tensioner which is also a counter bearing for the motor and intermediate shaft at the same time.
  • Reinforced bearing of the free-wheel pulley.


Chassis innovations:
  • New landing gear with appropriate proportions, produced using force transmission optimised carbon fibre sheets for more stability during hard landing manoeuvres.
  • New antenna holder for a save radio transmission despite the use of carbon fibre canopies.

Tail rotor innovations:

  • Boundary layer hardened tail rotor hub made of high-strength heat treatable steel.
  • Tail rotor blade grips with a new, extreme narrow design which lead to a better aerodynamic resistance and less weight. This is possible due to the first-time use of crash resistant needle bearings in tail blade grips. Furthermore we use bigger thrust bearings.
  • Cone-shaped tail boom (Diameter reduction from 38 mm to 30 mm) from our own production with a special carbon layer structure for minimal weight, maximum stiffness and the leave of tail struts.
  • New tail belt with 7,4 mm wideness.
  • New tail rotor housing with bigger tail rotor bearings (6x15x5 mm).
  • Tail boom tensioner for an easy adjustment of the required belt tension.


Rotor head innovations:

  • New swash plate design for lower load stress on the ball sockets. Especially in the low rpm range big angle of attack appears resulting in higher forces.
  • Stronger rotor head linkage (3 mm) with bigger ball sockets.
  • Revised feathering shaft with more wall thickness and easy thrust bearing assembly support.
  • Improved rotor head dampening with new, temperature insensitive silicon o-rings and the possibility to use three o-rings.
  • Optional: Thrust needle bearings from in-house development and production for a permanent wear-free application while flying extreme high rpm and heavy rotor blades > 800 mm.


Mass distribution innovations:

  • Longer intermediate shaft for a higher motor position and center of gravity closer to the rotor plane.
  • Torque effect reduction of big Motors.
  • Better flight characteristics with less energy consumption.


Canopy innovations:

  • New canopy design with improved visibility and enough place for big speed controllers with additional heat sinks.
  • Very good aerodynamic performance, due to the canopy wideness of only 110 mm and the closed rear side, for speeds over 250 km/h.
  • New integrated canopy mount from in-house development:
    • Clear lines without gaps,
    • easy use fastening and removing,
    • secure fastening in flight,
    • low weight.
