Hi! Tony William and all,
Hey ! Don=99t put me down as an authority on all things electrical
please. No way am I competent in this regard. However I would expect
that a relay does two things One :- it acts as a preliminary switching
device to save full power going through your micro switches . Two :- it
ensures that the polarity of the current is not crossed in a circuit
that employs reversed current operation.(Like in duplicated switching of
the same operation from both panel and control stick top.
The original Europa Kit no doubt presumed that you will utilise a switch
big enough to handle full power but then left you to get the switches !
NOW perhaps someone will pop their heads and help you with some better
knowledge on subject than me. please.
Regards
Bob Harrison G-PTAG

Hi Bob and William,
Here is the relay deck. Not sure why we need one, or if, as to my
knowledge I was never supplied one, nor have I checked the manual to see
if it is included in the wiring diagram. Pretty remiss of Europa if the
servo actually needs one of these things, which is why I am wondering if
it is a mod, Bob. It says for every servo you need one of these relays.
Does anyone know what they actually do, and why it states they are
needed? I can run my servo directly from a 12 V power supply with no
problem.

Hi! William.
The question initially has revolved around the length of the control
stick and loads needed when out of maximum trim.
My issue was nothing to do with the trim motor, however in your position
you should plan the securing of it so that you would be able to remove
it in an unlikely eventuality of failure because when the top is on it
is a bastard to access. However recently there was much chat about the
plastic clevises needing 1/8=9D removed from their threaded ends
before linking them with the brass threaded rod to facilitate more
movement of the trim and stabilators on final inspection.( Hopefully you
picked up on that ?)
My trim reversal problem was not to do with the trim motor but the relay
deck it had an inherent fault which became masked once the motor had
travelled to full trim and I had numerous major debates with the
Menzemer chaps always culminating in them alleging my wiring was at
fault. Until one day I had yet another event and when I contacted them I
discovered that they were now supplying the MARK II relay deck which is
faultless but of different shape also making it an arse to shift things
around on the back of the panel.
You need to shout out on the Europa Club pages as to how many others
have had this problem and then probably =9Cbite the
bullet=9D and get the MARK II fitted and done with it.

Thanks...but you had a runaway trim? if is was a particular model I am
wondering whether I shd change my trim motor (Mac) prior to putting the
top on (I cant imgaine this is much fun with the top on!)

Hi! William
................Just don=99t shorten the control stick ......use
the bent one and fix it by rotating it to best position.

Thanks Bob. That is about what I suspected.

Answer:- NO SHORTER WHATEVER. TO LAND FULLY NOSE UP TRIM IT WOULD BE
Extremely difficult on your own ! but power assisted by the passenger
probably ! But the extreme loads are a question over the mechanical
strengths of the linkages ! When I had to go to fully trimmed up to get
the damn relay deck to reverse it was easier to let it go fully nose up
trim and pray the deck would let itself reverse when it got to the end
of travel. Been there done that when Menzimer was insisting my problem
was wiring when in actual fact they eventually discovered that the end
of the travel by the relay masked the actual problem in the relay .
Since I fitted the MARK II relay deck never a problem !!!!!

Question for those who have test flown their Europa.
How far can you shorten the control stick and still comfortably land the
aircraft with the stabilizer stuck at full travel in either direction ,
without being Superman?
