| Ray Allen trim systems were designed specifically for experimental aircraft. Ray Allen servos are small enough to fit in individual control surfaces or can be used with lighweight springs acting directly on the control system.
Ray Allen trim systems also come with RS2 rocker switches and RP3 LED indicators. All Ray Allen indicators operate off of feedback sensors located inside the servo. These feedback sensors are purposefully isolated from the power supply to the servo motor to guard against possible electronic failure. Ray Allen trim systems also come with a RC8-7 clevis/pushrod kit.
Ray Allen has three different T2 and T3 servos available:
T2-7A Trim System has .7" (17mm) travel
T2-10A Trim System has 1.0" (26mm) travel
T3-12A Trim System has 1.2" (31 mm) travel
In addition, we also have available the T4-5 Trim System which has .5 inch (13mm) travel. This servo does not have a compatible indicator. |
