Add Classified Feedback | SOLD SOLD SOLD SOLD: EFR-801 electronic needle valve controller. $105 shipped within the USA. Shipping elsewhere extra. Payment by money order or Paypal (add 3% for Paypal).
The EFR-801 is an electronic needle valve controller. The unit includes a thermocouple, solenoid valve, and a control box. The thermocouple is mounted in the muffler mounting flange and measures the exhaust temperature. The solenoid valve is placed inline between the fuel tank(s) and the carburetor, and meters the fuel according to the engine temperature. The control box has a small processor which calculates the modulation of the solenoid valve based on the exhaust temp and the throttle setting. The throttle servo, receiver, thermocouple and valve solenoid all connect to this control box. Everything is powered via the receiver from the existing flight battery. The EFR-801 reads engine temperature off of the header and via a small computer processor, changes your engine mixture settings for you automatically!
It works well, and instructions are of course included.
