5. 3Range Testing Your R / C System ^
Please note that d i f f e r e n t systems demonstrate d i f f e r e n t range checks and the same system w i l l
range check d i f f e r e n t l y i n d i f f e r e n t conditions. Also,the r e c e i v e r antenna's i n s t a l l a t i o n a f f e c t s
the range t e s t — e x i t i n g the top of the model i s i d e a l . This i s a b r i e f explanation of range t e s t .
For more in-depth s p e c i f i c s onreceiver antenna mounting, additional checks i f u n s a t i s f a c t r o y rage
i s demonstrated,range checking with gasoline powered engines, etc,please see our F. A.Q.page at
www. f lyskychina. com.
. Leave the t r a n s m i t t e r ' s antenna r e t r a c t e d and be sure both b a t t e r i e s are f u l l y charged.
. P l s i t i o n the a i r c r a f t away from w i r e s , other t r a n s m i t t e r s , e t c .
Test one-engine/motor o f f , minimum of 1 0 0 f t . range:
. Have a f r i e n d view the model but not hold i t , engine o f f . (People conduct s i g n a l s , t o o ! )
.Walk away from the model,working a l l c o n t r o l s c o n s t a n t l y . S t o p when the servos j i t t e r
s i g n i f i c a n t l y ( a j i t t e r here and there i s n o r m a l ), c o n t r o l movement stops(PCM),or you lose
c o n t r o l a l t o g e t h e r .
.Measure the d i s t a n c e . I f greater than 1 0 0 f e e t , great!Proceed to Test 2. Less than 1 0 0 feet of
range check means you need more information to determine i f your system i s safe to f l y . Please
see out web s i t e or c a l l support f o r a d d i t i o n a l t e s t s to perform before f l y i n g your system.
.Repeat with f r i e n d holding the model. Note any d i f f e r e n c e s .
