Electric Aileron Trim System

Installation of the Ray Allen Company, Inc. electric servo, connected to the servo tab on the aileron, is a worthwhile modification. You can eliminate the existing springs and cable system, which reduces the control friction and gives the ailerons a lighter feel. The system can be installed during construction or on a finished aircraft.

If you are interested in this modification, you can contact Doug Poli for detailed drawings of installation or complete kits. See drawing below.

Electronic Ignition

ElectroAir offers an electronic ignition unit that works well and is a breeze to install. Jeff Rose, owner and designer, has developed a timing unit that takes the place of the removed magneto so there are no remote mounted pick-up coils. The ignition unit is self-contained on one tray and is easily mounted to the firewall. You can use automotive spark plugs and you do not have radio noise problems associated with unshielded high tension leads. A sample drawing of the electrical hook up shows the simplicity of the system. See photo below drawing.

Power Pak Fluid Recovery Can, “Burp Cans”

When checking the “Free Fall” Landing Gear Extension System, we all know that you will lose some fluid out of the overboard vent. The large capacity can catches the fluid that would normally go overboard and drains it back into the reservoir. For more information and kits contact Doug Poli. Two drawings and photo below.
