Subject: | Re: Home made soft start module for Rotax 914 |
I concur with Robert on this, My 10year old 914 hasnt been a problem
starting using the standard starter motor,
remember its basically a low compression 912 with a turbo, the soft start
was more for the 912s with the higher compression to stop kick backs,
some start using just the A mag then switch on the B mag when she starts
to fire, i personally havent bothered because its never been a problem,
spend your money elsewhere IMO

Me too. It has always been my impression that the soft start is only
applicable to the 912S. My 914 which must be of a similar vintage has
been starting effortlessly on both mags since 2002 In standard format as
supplied by Europa.

Thanks Ivor and Bob,
All the stuff I have read and watched relates to the 912 including some scary videos
of the damage the kickback does. I assumed that the 914 was equally affected
but your experience is interesting and with the lower compression of the
914 is logical.
The lead acid batteries of course arrived dead, so I am upgrading to Earthx lithium
iron phosphate batteries are a fraction of the weight of the old ones and
put out more AMPs I am told, when required for starting. This should help also
to avoid the damage which apparently is compounded when the battery is low and
can cause it to kick back repeatedly without starting.
Thanks again gentlemen for your advice, is there anything else I should consider
changing ? I am told the older style crankcase can cause crankcase fretting
issues but clearly this is a big job so would prefer to avoid this and the sprag
clutch has been improved to make it stronger.
It has also been mentioned that the carburettor jets on the early type could be
upgraded and perhaps some other things - all advice welcome as I am a newbie
to the Europa (one hour type training so far) and the Rotax, but have owned a
GA aircraft for many years.
Kind regards
Trevor

Subject: | Dynon FlightDEK D180 |
Hello All,
With my incomplete kit arrived a FlightDEK D180 still in the box. Investigation
indicates this is an early one before the Super Bright option arrived. I personally
prefer round dials not simulated by a screen, so I am thinking of "going
back" to getting nice round clear instruments for my finished kit.
Does anyone have experience of the older FlightDEK D180 and if this is worth pursuing
and what advantages if any there of the EFIS are over nice clear round
dials which fail independently. It looks to me that it just saves panel space
and looked cool perhaps 10 years ago... to me they just seem hard to read. Apparently
it can be "upgraded" to the bright screen for $400, but of course it will
still be the small screen.
Thoughts ?
Regards
Trevor

Trevor, The gas recombinant Odyssey battery works extremely well with
the 914 has incredible torquing power and is relatively light,
maintenance free and not expensive.

Subject: | Warpdrive pitch for 912ul |
As i have to replace my damaged fixed pitch propellor I need to identify the required
pitch angle.
Could anyone give me some idea of the optimum pitch setting.

Trevor, I learned the hard way that having a separate starter cranking button can
be very useful. My present engine's an 'S' with high compression and I agree
totally with what the other respondents have stated. My original engine was
a 912UL and never gave starting difficulties, having the same/similar compression
to the 914.
However if you opt for a heavier propeller such as the Airmaster and some day find
that your battery has low charge, then "kick-back" is a possibility because
the propeller inertia needs to be overcome before giving the engine sparks.
First press the separate starter button for 1 or 2 seconds before either flicking
the "mag" switches to ON or turning the ACS key to BOTH.
This technique is used by many/most pilots who have the 100hp 'S' engines with
heavy propellers, or so I'm told. The "hard way" mentioned above involved having
to replace the sprag clutch after repeated "kick-backs". A separate starter
cranking button is a simple and cheap option.

Thanks Johnathan,
Separate starter and mags makes sense - this is a bit like starting the Stearman
or YAK52 - Ha - you have to get the thing moving first before engaging the ignition
coils.
I will do this with the wiring then.
All feedback much appreciated
Regards
Trevor
