The new Roto 125 FS is completely maintenance-free, has high performance and is also suitable for use in aircraft such as the towing machine.

Our developers have managed to tune the engine for the use of propellers with a large pitch to achieve a realistic sound, and therefore we recommend for the Roto 125 FS engine a propeller with a pitch of 14 "Propeller diameters are from 28" to 30 "for two blade propellers.

The maximum engine power is up to 6 kW.

A unique novelty on Roto 125 FS engines is the factory-installed carburetor control. To control the throttle, we chose the Savox SV-1232MG servo, which is verified in practice on our UAV projects.

The reason for this improvement is to make it easier for customers to install the engine on an aircraft, just connect the servo to the receiver and set the servo deflection. The customer does not have to deal with servo levers or drawbars, everything is original from Roto.

ROTOmotor 125 FS is a twin cylinder 4 stroke inline gasoline engine.

The Engine was developed in Europe with the assistance of CAD systems (Solidworks) and optimized for the liquid flow in the Flow software (made by Solidworks).

All ROTO engines and its components are made and programed by utilizing the state of art 5 axis machinery made by American companies HASS and Siemens NX.

Every engine, made by ROTO MOTOR Company is bench tested and adjusted by qualified technician on the Engine Star equipment to ensure its peak performance.

The manufacturing process involves nothing but state of the art equipment including the latest in CNC cutting technology.

Nice shirt. Wrinkles alot.
Size: 4X-Large Big, Color: Light Grey Vertical Stripe
Like the style and construction of the shirt. Fit and finish are as expected. Unfortunately the fabric wrinkles easily. Definitely requires ironing. Wish this shirt was a wash and wear but it's definitely a wash and iron before wearing shirt. Otherwise I have no complaints. Fabric is lightweight and could be used in summer as a dress shirt.

Very nice shirts
Size: Large, Color: White
These are a heavier fabric than I was expecting but that’s fine since it’s winter. They barely shrink being washed in hot water and dried in a hot dryer. I was actually hoping that they would shrink a little more after losing 40 pounds. But they shrunk just a little and they fit just fine. Also, if you take them out of the dryer immediately there are very few wrinkles.
