Wing and Spar Tubes
Get rid of that heavy, outdated aluminum and get into Carbon Fiber!!
Light weight and Looks great!! Cannot bend or break. CF tubes are about 1/2 the weight of aluminum tubes, though some aluminum tubes are way too thick and in those cases, the weight saves is tremendous.
We have a new supplier, and are able to offer you much lower price than anywhere in the world.
The first tube we designed was for Carden planes. Cardens are/were heavy and easily bend the stock aluminum wing tube in high G maneuvers. It turned out that the tubes were also lighter, so some people replaced their stock aluminum tubes with the CF tubes to save weight, though the original intent was to be stronger.
WING TUBES: How easy is the installation?
1) Remove aluminum wing tube and give to son for baseball bat. 2) Slide CF tube in place. How easy is that? We've jumped on the wing tube, we smacked it on cement in 30 degree weather, we've flown the heck out of them and they don't fail. You will throw 10 planes away before you even nick this tube. Is there any other product that offers that? No way. You will never need another wing tube in your life!! There are thousands of CF tubes in use today.
These tubes are manufactured by winding CF filament around an aluminum mandrel, then impregnating with resin. Curing at an elevated temperature and pressure, and then sizing the OD by sanding. The surface is treated for improved appearance. The resultant tube is extremely hard, much harder than aluminum. The weight and size is very consistent, unlike the aluminum tubes made today which are badly out of round.
When a 250 lb man stands on the tube with the tube supported off of the ground, the tube barely deflects much less starts any crack!!
We can't cut off the tubes for special lengths though they are very easy to cut, just use a fine blade hacksaw or a dremel type cut off tool.
WARNING: CF is some nasty stuff!! While you drill, cut or sand CF parts to fit your application take precautions to avoid breathing the CF dust and to avoid getting CF splinters. Your body does not naturally repel CF, your body will make some inflammation tissue around it and the CF splinter will stay underneath your skin or in your lungs. Use a vacuum cleaner and a dust mask when machining or drilling the gear. Be very careful to not get the dust inside your house or to breathe it in.
IMPORTANT NOTE ON SIZING: Most wing tubes fit well, though wing tubes vary in size as do the sleeves in airplanes. The difference between a tight fit and a loose fit is very little, about 0.005". The tubes are manufactured slightly undersized so they will fit into sleeves which are properly sized. If you can accurately measure the tube you have and can tell us precisely the size you need, we can find one that will match the closest. If you receive a tube which is too small or too large, you can adjust the size yourself by sanding the large tube or using CA or paint to enlarge a small tube. Or you can return it and ask for a tube which is larger or smaller than the one being returned. We will do our best to get the best tube for your application.
WARRANTY: Wing tubes have a 30 day warranty against manufacturing defects.
Need a sleeve for your CF tube? It's easy to make. First wrap the CF tube with wax paper, wax side out. Then wrap the wax paper with several layers of glass cloth. Then apply a slow curing epoxy. Trim the ends, then slide off of the CF tube. You can leave the wax paper in place or remove it, either way.

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.
