Jos Hi!

NO! you'll have to put up with peaceful coexistence!

Your comments......all valid and taken notice of.

The interesting thing is that already amendments and modifications are being
produced for the device based on a small amount of operational use.

I tend to agree that the TRIM Motor is a dubious component in the system
especially if demand is made of it by frequently by EZ-TRIM adjustments.

At the time it was devised I think that only S-Tec had any sort of pitch
control that was affordable. Hence a privateer design to help Home built
activities.

It can be disabled easily if a nuisance and I've wired mine via DP PL/SK
arrangement so in fact it could be scrapped if not useful at all. My only
other fitment was the Matronics Governor unit that allows singular TRIM
selections from multiple switch sources and also has provision to adjust
TRIM speed. It could be that this will further complicate the EZ-TRIM setup
but it also may have the benefit of allow more accurate manual trim settings
to hold pitch attitude if EZ-TRIM abandoned. The standard pitch adjustment
speed is a little on the excessive side at faster speeds, especially in
cruise.

I'll watch this debate move forward and await with interest as to where it
will go.

The challenge of making it and getting it going is fun enough for me and it
may well end up as many of my other diversions whilst building the Europa...
extend the build time, deplete the bank account and bring a smile to those
others that are wiser or have been down that same road!!

Kind Regards

Gerry
