Use at your own risk........all I am saying is that I personally could not get CH 3&4 to do anything(basically dead on my unit).
So, I have a HL Tiger 1 that drives nice...but has NO turret function[&o]
Also.....they did NOT "meter out" anything with a multi-meter..............
Maybe I just got a bad unit......
This Tiger is now my "hanger Queen" for spare parts


I personally will never buy one of these again....but, thats just me
PS-on a side note..........even with capacitors installed....is VERY noisey!!!!!!!!!!(high pitch whine)
