Question: My VMAR Aero Subaru 06-15 ARF was supplied with control horns that appear to be made of wood. Are these OK? 

Answer: Yes these are laser cut from aircraft plywood and are strong, light, reliable and easy to install.

Additional Information: There are two styles of control horns used on this model.

• Style A: Please see Page 2, Stage 1, Picture 1A. These are used on the ailerons and are inserted into pre-drilled holes in the aileron using 30 minute epoxy as shown in Picture 1D, 3B and 3C.  
• Style B: Please see Page 9, Stage 13, Picture 13A. These are used on the rudder and elevator and are to be inserted into pre-cut slots in the rudder and elevator using 30 minute epoxy as shown in Picture 13C, 13D and 13E.

After installing the control horns, we recommend wicking thin CA such as Pacer ZAP (Pink) into the plywood of the control horn to "harden" the plywood and holes. Do two applications about 1 minute apart.

Please see Page 7, Figure 11K. This figure shows the 3mm nuts evenly spaced at .500 in. (12.5 mm) from the firewall. This works well for many motor shafts and may be shortened or lengthened to reflect different lengths of motor shafts. The important thing here is that the motor shaft be able to extend through the front of the cowl and still securely hold the propeller without the propeller contacting the cowl.
