I've been rebuilding my Slo V and testing the throw on the servos. I think I discovered my problem that led to the crunched fuse....the trim 'sliders' on the controller have almost no friction, no detents. It is so easy to bump the 'sliders' and throw the trim off that I think thats what happened. Is this true of all Park Zone controllers or did I get a defective unit?

And .... if this is true of all of them, has anyone tried fixing the 'slide' switches?

MCRUSS,
I have 3 of them, all the same. I've had cases apart, don't remember any adjusters.
Hint: I took a Dremel tool with a cut off wheel and trimmed the slider knobs almost flush with the case. No more bumped sliders.
