SAET-M90 Shulman Aviation Medium E~Tract 90-Degree Set

Scissor Link Oleo Mains Ideal for Top-Flite P-51 or Hangar-9 and ESM Planes

Scissor Link Oleo main E-Tracts are the perfect upgrade for most airframes up to 15 pounds.

Add the realism of functioning Electric retracts with fully machined suspension struts  to your airplanes.

E~TRACTS are a completely self-contained retract system that does not require any Special box, air tank, complex linkages, or even extra servos. They simply need to be bolted into place and plugged into the receiver. A specially designed Y or W-harness is also included, allowing pilots to use a single receiver channel to control all retract units.
