adjusting the low side to me can be most dangerous if you do it while the engine is running using a screw driver. I have seen several propellers shatter, this happened to me once and I learned my lesson. I was lucky the propeller was all that got damaged. most people don’t wear safety glasses when working around a running engine. I was a mechanic all my life and have had my eyesight saved several times thanks to wearing safety glasses. we all have made dumb mistakes at one time or other. I like the remote high end screws, but like anything caution and common sense is always needed.
