Pilot-RC Yak build

Here you will find a pictorial update on the building of my YAK54, in the “Madd0g” design……


This will be the servo used on all rudders:

Savox SC1256-TG combines leading edge technology with a super high 12 bit (4096) resolution and Titanium Gears. Extremely powerful with 20kg-cm torque at its size Extraordinarily light in weight, 20% lighter than its kind in the field. The Coreless motor inside has brought the output performance to the top level – smoother, faster and more efficient. The metallic case design not only exudes an exquisite style but helps the servo to stay cool and smooth. Super strong and precise-made Titanium metal gear form as the solid framework of this servo. Totally Green from material to production, our servos are environmentally friendly. Ideal for TOC, steering servo on 1/8th scale Buggy, Monster Trucks and Rock Crawlers
