We got rid of tubing. Now you can put even the largest aircraft with the wings attached on the stand and you still are able to roll it to the right and to the left without interfering with the stand structure.
We named this design “Barless”.
The number of this new item is RP-0052.

The old one (RP-012 is discontinued) Upgrade Kits for this model are still available. The most current one
(RP-052 and RP-090) - are available. The previous versions of Snap-Stand remain the
same. New version gives you much more versatile opportunities. All
sizes and woods are available. Please check price-list and photographs. You’ll love it!
And finally, if you already have previous versions of a Snap-Stand, you can upgrade it without buying a whole new stand. Just purchase an upgrade kit, item number RP-052-07. It fits to any version of previously sold stands. And if there is a need you can switch back and forth from one version to another.
New industrial grade ball-ends now in stock. All made in Germany by INGUS. Rod-end size is M3 or 4-40. All come with M3 bolts, washers and nuts.
After certain amount of new tests and researches we had developed upgrades for the Snap Stand. What is it you would ask?
It is an actual mechanical upgrade of some parts of the stand. We thought about the planes of a super giant scale. The upgrade increases the diameter of the aluminum tubes, as well as side plywood brackets have a thicker and wider wood.
The utmost good thing about this upgrade beside the increasing of durability is fact that you don't have to buy a whole new Snap Stand but rather remove the top part of it and replace it with new
few parts and a little wider webbing. We also decided to keep 3 original styles of the wood that we used from the most beginning till now. Thus the upgrade kit comes in 3 different wood types: Poplar, Oak & Maple. Starting as low as 49.99$for Poplar upgrade kit for 530mm long Snap Stand. Another new feature of a snap stand is a 2 color webbing: Purple and Gold. Please specify which color would you like when you place your order online.

New design of the transmitter tray will fit almost any JR, SPECTRUM and FUTABA transmitters.Transmitter tray gives your hands absolute freedom to operate the sticks precisely and reach any switch on your radio during the flight without accidental affecting sticks movement.
It’s made of white acrylic and 6061 aluminum extrusion. The transmitter is secured in place with the simple nylon “WELCRO” strap at the bottom of the tray.
Removable hand rests and adjustable nylon strap are included.
If you prefer narrower hand rests, additional “wings” (removable hand rests) can be removed instantly without any tools. With removed wings the tray with transmitter fits to the standard aluminum case. When it’s needed you can install it back the same easy way.
This tray works well for both “thumb” and “two fingers” pilots.
Very neat design allows easy excess to the charge socket, bind button and even to the battery compartment at the bottom of transmitter.
The tray will also protect your transmitter when you put it on surfaces like wet grass, dirt, asphalt or concrete. The tray’s normal position is horizontal but it can also stand vertically if needed.
WHAT TBS SYSTEM IS?
TBS allows to gang two, three or virtually unlimited quantity of servos together to increase output torque on rudder or to anywhere. If surface is large, one servo is never enough.
WHAT PROBLEMS ARE WE TRYING TO SOLVE?
There is the main problem of commonly used co-called Bell-Crank System, which uses ball-ended push rods and servo arms to connect servos and the bell-crank.
This problem is - adjusting bell-crank system. To have whole system work properly and to avoid servos to fight each other you have to make the length of each push rod absolutely the same. Technically it’s almost impossible so there is some difference always. We just cannot see this or measure it but it exists. And it’s also some loses of power.
There are some limits of the angle you can turn your rudder using bell-crank. It’s because of at some moment the rudder horn sets against the fuselage and it limits the angle of deflection. In order to increase the deflection it is impossible to keep enlarging the rudder horn size till infinity. Using pulley-pulley system you’ll have no limits of it. You can experiment with any size of deflection!
WHAT THE NEW APPROACH IS?
Our system is an absolutely new approach to solve the problems mentioned above.
First of all this system keeps the torque steady all the time regardless the angle of deflection.
It happens just because we use so called Timing Belt, which is commonly being used for millions of different purposes everywhere. You can find these kinds of belts almost in every machine: starting from printers, faxes and scanners on your table and up to the cars, motorcycles, elevators, transporters and etc, you name it.
By unknown reason it was used everywhere for tens of years except model aircrafts industry. But it’s not anymore. We have done it.
Timing Belt is actually just a tooth belt. It’s very flexible and very robust belt made of special rubber reinforced with glass fiber. This product of highest quality made in Germany. Obviously it speaks for itself.
There is no need to lubricate it, or to strain it. These belts work precisely without any creeping or play transferring gigantic forces. The only play you have is the one, which is in the servo gear. But there is unfortunately nothing we can do about it.
The tooth pulleys made of very strong and rigid fiberglass filled plastic. Each pulley can be installed on top of each other, letting you design practically any configuration of the system.
DIFFERENT CONFIGURATIONS
We currently designed three commonly used configurations. TBS-2 designed to gang TWO servos together. TBS-3 designed to gang THREE servos together. TBS-4 is ganging FOUR servos together. There is also TBS-1 (not shown) which just allows you to transfer the torque from the single servo to the bell-crank or the pulley. It allows you to transfer the force to the cable, which pulls the rudder through the same bell-crank so the bending moment, which is created by tightened cables, is not being transferred to the servo shaft. You can use it for smaller aircrafts. (Servos are not included!)

There is no fundamental difference between systems TBS-1, TBS-2, TBS-3 or TBS-4. The only difference is the size of the base made from aluminum and quantity of the pulleys and belts used. All parts are standardized. You can use standard size servos of any brand you wish. TBS system allows you to adjust it easily. For example if Hi-tech servos have 48 mm distance between mounting holes, at the same time standard Futaba servos have 50 mm between similar holes. The same servo tray (Base Plate) could be used for different brands. Servo mounting adapters have special slots so you can position the servos exactly where it is to be.
If you want to get full advantage from this new system, and it’s HUGE, one very important thing must be done. Some day you’ll have to reject bell-crank. You will have to place pulley on output shaft. If you place absolutely the same pulley at the bottom of the rudder and join them with regular cable, you’ll get this advantage. No more heavy and cumbersome cranks. The rudder deflection becomes unlimited.
In some aircraft designs TBS even allows you to make cables invisible. By the way, we are going to use this system in to our new ARF kit, which is coming very soon.
If you are not ready for this yet, it’s ok. We have bell-crank as well, which could be installed on top of output pulley. And you still have some advantages, which TBS system gives you. If you don’t want to use pulleys and belts, you can buy our SERVO TRAY set WITH BELL-CRANK and keep using ball-links and push-rods. Output pulley has two ball bearings as you can see at the pictures. You can also design your own system using TBS spare parts.
WHAT’S THE ADVANTAGE OF USING TBS SYSTEM?
First - you gain the power. You don’t lose energy to make servos to fight each other. You keep the same torque and angular velocity regardless the angle the rudder turned. If you wish it can be rotated 90 degrees or even 360!
Second - the adjustments are simple. Just install the pulleys on the servo shaft and sub trim it till tooth on the belt seats between proper teeth on the pulley.
And finally third – it’s just cheaper! It’s because we use very effective and at the same time simple tools to manufacture our products!
