Stingray Engine Options

The Stingray UAS can ship with or without an engine. The two engines typically used in the Stingray are the AR731 rotary engine or the AR741 rotary engine. These engines can come fuel injected for use over 5000 ft, or without fuel injection for use under 5000 ft.

These are not a high endurance engines. If you have interest, we can substitute a ZDZ or other gas engine which has greater endurance.

AR731

The AR731 has the highest power to weight ratio of any rotary engine in the world. It has been specifically designed and developed to be the ultimate engine for small target drones and short-life UAVs. TBO (Time Between Overhauls) is 10 to 50 hours depending on duty cycle.

This remarkable power unit offers many advantages over previously competitive twin cylinder 2-stroke engines.

AR731 Design Features

  • Exceptionally high power to weight ratio.
  • Small frontal area concentric to propeller axis.
  • Low specific fuel consumption (allowing greater range or payload).
  • Low levels of vibration.
  • Both tractor and pusher versions available.

AR731 NOTE

Certain design features of the engine are covered by British, U.S. and other foreign patents.

AR741

The AR741 has an outstanding power-to-weight ratio combined with much longer life and better SFC than any alternative engine. It has been developed from the mature AR731 target drone engine to meet the needs of small surveillance-type UAVs. The engine has successfully completed a 150 hour FAR-33 type endurance test.

AR741 Design Features

  • Exceptionally high power-to- weight ratio.
  • Economical fuel consumption.
  • Low cross sectional area.
  • Low levels of vibration.
  • Long life

Allied countries of the United States regarding shipment of any products from TBM

WARNING - Gasoline and Turbine powered R/C model aircraft are not manufactured to withstand unlimited G's. Any R/C model aircraft can fail, be it a wing folding up or a fuselage breaking in half under too high of a load. Just as any full size aircraft, model R/C aircraft have a maximum G rating. Because you are not in the plane flying it and experiencing the G's and reading the G-meter, it is more difficult to judge the G's on the aircraft, and it is very easy to exceed the limits of the aircraft. Understand that if you perform a snap roll, parachute, wall, blender, knife edge loop, or pull hard on the elevator at almost any speed, you can be putting in excess of 15 G's, even in excess of 30 G's, and most aircraft can only designed to take 10-12 G's. If you perform any violent maneuver, you can break your plane. When I perform hard maneuvers, especially for the first time on an airframe, I am prepared for a failure and am prepared for it as best I can be. This mainly includes performing the maneuver far enough away from spectators that in event of a failure that I am not endangering others. In addition, be prepared for the manufacturer to not pay for a new airframe which is broken during flight. It is common practice for any manufacturer to not replace an airframe which breaks in the air or upon landing. I have only seen manufacturers replace airframes when they have received many of the same failures and the manufacturer determines that there was a design or manufacturing error. If you break an airframe, and you are the only one to do so, then it is probably not the fault of the manufacturer. Please fly safely, and avoid full throttle operation other than at low airspeeds.

R/C model jets, warbirds, aerobatic planes and UAV Unmanned Aerial Vehicles to name a few are not a toy! If misused, it can cause serious bodily harm and property damage. Fly only in open areas, and AMA (Academy of Model Aeronautics) approved flying sites. Follow all manufacturer instructions included with your plane, radio, servo's, batteries and engine. Aircraft manufacturers guarantees each kit to be free from defects in both material and workmanship at the date of purchase. This warranty does not cover any component assembled by the customer. All parts of high stress must be inspected and reinforced if necessary by a competent builder. Some parts should be glued again. High stress areas such as firewalls, motor boxes, wing mounts, landing gear mounts, etc., are areas of high concern. Seek help if necessary. In not case shall TBM be liable for the cost of any product it offers which is not manufactured by TBM. The liability to the manufacturer cannot exceed the original cost of the purchased item. Further, TBM reserves the right to change or modify this warranty without notice. In that TBM has no control over the final assembly or materials used for final assembly, no liability shall be assumed nor accepted for any damage resulting from the use by the user of the final user-assembled product. By the act of using the user assembled product, the user accepts all resulting liability. The kit manufacturers have provided you with a top quality, thoroughly tested kit and instructions, but ultimately the quality and fly ability of your finished model depends on how you build it; therefore, we cannot in any way guarantee the performance of your completed model, and no representations are expressed or implied as to the performance or safety of your completed model. It is the user's responsibility to inspect each component for worthiness.
