BRISON

2.4 cu in: This gasoline engine is well suited for the One Design (12 lbs.) and has been used extensively. Vertical is unlimited. The combination of the Brison 2.4 and One Design was used to win the NC region Unlimited IMAC competition in 1998 by Dave Genovese. This engine has been used on the Staudacher as well. The engine is mounted inverted in either case, with a Pitts style muffler. The One Design has a larger cowl which hides more of any engine which is mounted inverted. The Staudacher has a low cowl and fuselage so the engine protrudes more.

3.2 cu in: This really is too powerful for the One Design or the Staudacher though it has been used on the Staudacher. If used, the engine should never be put at full power unless pointed upwards. The plane hovers at just a few clicks above idle.

3W

48cc twin: This is an excellent gasoline engine for the Staudacher as it fits completely within the cowl (even the spark plug caps). It has a very scale appearance as you see the two cylinders through the air inlets in the cowl. This combination is good for any level of IMAC flying. 14.5 lbs.

3W engines are imported into the US by both Aircraft International and Cactus Aviation.

RCS

1.2/1.35 cu in: For sport flying these alcohol engines are great.

1.8/2.1 cu in: These alcohol engines are great for IMAC flying. A Cline regulator (or equivalent) is recommended. The 1.8 is used extensively in the One Design (10.5 lbs.), while the 2.1 is used extensively in the Staudacher (11.6 lbs.).

RCS engines have high compression ratios so they use FAI (no nitro fuels) so the fuel costs are minimized.

SAITO

1.5/1.8 cu in: These alcohol engines are good for sport flying and more, but don't provide gut wrenching unlimited capabilities in either aircraft.

3.0 twin: This powerhouse fits into the cowls of the Staudacher and One Design, and has unlimited vertical capabilities in either. It looks great as the jugs can be seen through the air inlets of the cowl. Many pilots use 30% nitro heli fuel which can get expensive with this thirsty engine.

Saito engines are distributed by Horizon Hobbies.

MAC MINARELLI

We have tested the Mac Minarelli 85cc engine and found it to be an excellent performer. The engine starts effortlessly, is powerful, has excellent transition, and is one of the smoothest engines we have ever tested.

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.
