No feedback on my previous question ! Well , kind a use to that in forum's
so i try one more time,
Now it seem's that my Focus 4 went south without a goodbuy and now i wonder if there is any way to obtain a wiring diagram or S/M for this radio ?

Regards
Kjell.

1. No manufacturers release proprietary information relating to the wiring of transmitters.
2. Focus 4 went out of production quite some time ago and replacement boards are no longer available.
3. refer "Focus" under sub section "Transmitter - FAQ - Additions, Adjustments, Mode Change, Clonepacs & Repairs." at:
Alan's Hobby, Model & RC FAQ Web Links

Hello, yeah it may be good with some specs on'it,
Tx is a 35Mhz and i bought a new Rx from UK also at 35Mhz Dual Conversion
to that i got 10 pcs of Hitec original crystal's brand new from a auction site
so now i have 5 matching pair with dual conversion " channels " for $11 ,
35 Mhz is perfectly legal for aircraft here in Sweden .
I also have electronics as a hobby so i dissected my old focus and i think i
found this problem ! in rear at the trainer output is a transistor all at the
edge of that little board and it's tracers are all cracked and of course it's
way to close to a smd so i moved'it to the side and runned 3 thin wires
between board and transistor and secured the same with some hotglue.
After a cleaning and adjustment i screwed'it toghether and powered'it up
Well well ! look at this i have a secondary complete radio system !
Thank you Alan for your time,

Regards
Kjell.
