Behotec E Line retract systems (up to 55lbs)

We are proud to introduce the new Behotec E Line Retracts based on the proven quality and reliability of our C36-2, C40 and C50 air retract series.

The special gear motor achieves an absolutely realistic retraction and extension action.

The electric motor is a very special design and uses an encoder for accurate retraction and smooth operation with over current protection.

Retraction and extension times are between 4-7 sec. The Behotec E-Tract v1.0 Control unit allows full programmability as well as proportional electric brake control (1.5 to 12V).

You can depend on the Behotec quality and Altecare's support to give your scale project an added touch

More importantly, you can pick and choose your retract system. Each retract unit is sold individually. You can mix and match to suit your project. Our large selection of STRUTS will fit all these retract units.

C21 retract set - 1 oz each retract unit

C21/C36 Retract - Brake valve instructions

The C21 retracts are air up spring down units. Any pressure loss during flight will cause the struts tocome down automatically.

The retraction angle is 90°. Unlike other manufacturers, our one part retract bodies with cylinder are machined from solid block (F50 specifications), and all aluminium parts are anodized to minimize wear.

This retract is extremely strong and very light. Set includes all necessary fittings as well as a retract / brake valve to eliminate the need for an extra servo. The C21 retract is compatible to the 602 Spring Air retract.

Set contents :

  • 2 main retract units
  • 1 nose retract unit
  • Festo tubing, Festo quick links, Festo filler valve, and air bottle
  • NEW 3 way actuating valve (brake operation)

Retraction angles of 75, 90 ( standard ) and 105 are possible. The retract bodies are available as standard in "flat mounted" or "front mounted" units. The 105 version is only available as a front mounted unit.The actuating valve is also able to operate wheel brakes without the need of a separate servo ! ( 3rd output )
