The Robbe FS 4509X is an extremely powerful and robust servo in a compact, CNC-milled standard aluminium housing with milled cooling fins for better heat dissipation. It has a brushless motor, a stable and backlash-free metal gearbox and ball bearings on the output. The FS 4509X has an enormously high actuating force of 45kg/cm at 8.4 volts and an extremely short actuating time. It can therefore be used in all aircraft categories on all control surfaces, especially in large models and jets. The FS 4509X is also the best choice for long-lasting control in RC cars or boats.

The new Robbe X series servos are precision-manufactured high-voltage digital servos in various sizes for different applications in RC modelling.
They have CNC-milled aluminium housings with cooling fins for better heat dissipation and robustness, metal/steel gears for low backlash and high positioning precision, high-quality ball bearings, coreless- or brushless motors, high protection against external influences (IP56) and a soft start function that moves the servos slowly and gently to the neutral position when they are switched on.
These features ensure a long and reliable service life for the servos and therefore also for your models.

BUY THESE
Color: Black, Size: 8
Shocked at how comfortable these shoes are. I spend a lot of time standing and moving around as an esthetician. I wore these 8-9 hours straight at work for 2 days and it was shocked at the comfort. They are just right height and cute with long pants. Super cute, I’m so glad i took a chance on these. I bought black and tan
