I have tried searching and I'm not finding the info I am looking for. I picked up a pitch control lever: http://www.amazon.com/gp/product/B00HKH ... UTF8&psc=1 You would think install would be rather simple. But it isn't. This part does not fit the transmitter. It almost looks like I have to trim the plastic "tunnel" in the transmitter body so as to allow the shaft to protrude far enough out the back to be able to attach the screw and also not destroy the adjuster itself? Am I on the right track with this?? There are NO instructions for this. (That seems to be a common theme with these add-ons, no info!) I searched on Youtube and found instructions for other types but not this one.
