OWNER’S MANUAL
INTRODUCTION:
Thank you for purchasing the FMA Direct Quantum 8 FM receiver. The new Quan-
tum series represents the fifth generation in a history of high quality radio control re-
ceivers designed 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 and Tetra. By incorporating the highest level of technology avail-
able to the R/C industry, FMA engineers are committed to providing 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 compliant, have limited
range and performance, and hence experience serious problems when used at typical
R/C fields. Quantum series receivers are designed with extremely narrow bandpass
and full-range capabilities. Furthermore, because they are dual conversion, interfer-
ence rejection on all fronts is unsurpassed. You may fly your Quantum 8 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 simulta-
neously. Available in two basic models to accommodate FM shift, the Quantum 8
supports either positive or negative FM modulation. As usual, superior RF mixer
technology and advanced circuitry for detecting and amplifying PPM information
enable the Quantum 8 to out-perform other single and dual conversion designs
presently offered. Heavy-duty, SMT construction on a single, glass-epoxy P.C. board
along with various other circuit improvements make our latest designs the most reli-
able we have ever produced.
