OWNER’S MANUAL 

INTRODUCTION: 

 

 

Thank you for purchasing the FMA Direct Extreme 5 FM receiver.  The new Extreme 

represents the sixth generation in a history of high quality radio control receivers de-
signed by FMA, Inc.  The latest trend in the industry has been the move to  smaller and 
smaller airborne equipment.  FMA pioneered these efforts with the micro 2000, Fotress 
micro, Tetra, Quantum and Magnum series receivers.  By incorporating the highest 
level of technology available to the R/C industry, FMA engineers are committed to pro-
viding consumers with substantial size and weight reduction while at the same time 
improving performance over previous designs.  This philosophy is vastly different from 
other manufacturers who rush to market smaller products that are not even 1991 com-
pliant, have limited range and performance, and hence experience serious problems 
when used at typical R/C fields.  Extreme receivers are designed with extremely narrow 
bandpass and full-range capabilities.  Furthermore, because they are dual conversion, 
interference rejection on all fronts is unsurpassed.  You may fly your Extreme 5 in 
anything from park or indoor models to sport models or helicopters to IMAA legal 
quarter scale aircraft with complete confidence regardless of how many pilots are in 
the air simultaneously.  In addition, the new microprocessor-controlled decoder pro-
vides additional digital filtering to further improve noise immunity while at the same 
time reducing overall size and weight.  Available in two basic models to accommodate 
FM shift, the Extreme 5 supports  either positive or negative FM modulation.  Heavy-
duty, SMT construction on a single, glass-epoxy P.C. board along with various other 
circuit improvements make the Extreme 5 design one of the most reliable we have ever 
produced.
