Subject: | Re: 914 Battery Locations |
I had a heavy MT prop and 2 x batteries (8 kg) in parallel on the footwell. I had
to put 2 kg of ballast at the tail. Recently changed to one Lipo on the footwell
and took out nearly all of the ballast!! Magic!

A friend of mine in the motorcycle trade after looking at the Rotax charging system
specified a 6.5kg lead acid. Two years later he suggested LiPo and after
7 years Im now on my second one. Its 800 grams and the first failed through age.
LTX9-BS and 80 delivered through eBay. I initially had concerns over an early
regulator failure but thats still original after 10 years and 700 hours.
Fully flooded and VRLA batteries have their place but possibly not in an aircraft.

Subject: | Re: Wheel pants help |
My tri-gear using the standard spats and wheels with 2 x vertical 1/8in lite-ply
formers set approx 2-3in into each main spat moulding. The nosegear spat has
a similar plywood former in the aft moulding. All spats have a 1/4in drain
hole on the underside.
In winter the mud accumulates in the void around the wheel, I normally remove it
using a [small] pressure washer. On odd occasions when it was left and has
dried it shrinks and is prone to lock a wheel when man-handling the aircraft on
the ground.
I once weighed the [wet] mud extracted - approx 10lbs.
If l was to redesign the spats l would add a mud-guard internally - set around
2in from the tyre outer radius. This would limit the mud but possibly also increase
the risk of it getting heavily bunged up.
All of my spats have carbon tows laid around the wheel aperture - this avoids splits
in the woven GF propagating. I leave around 1/2in gap around each tyre.

LiPo batteries are great for cranking amps but it is worth double checking the
capacity, particularly if you are flying an aircraft that relies on only electric
pumps ( 914). The LTX9 has a capacity of only 3.6 AH.

>>LiPo batteries are great for cranking amps but it is worth double checking the
capacity, particularly if you are flying an aircraft that relies on only electric
pumps ( 914). The LTX9 has a capacity of only 3.6 AH.<<
When I fitted a a LiPro to my 912ULS Tri-gear, I worked through the static load
i.e. Radio, GPS, Master Solenoid, Transponder. and then dynamic load i.e. Radio
Transmitting, trimmer and flap operation. With a static load of 8 amps I have
2 hours of battery capability and can extend that if I close down transponder,
put GPS on internal battery and other measures. In other words I can cross
the channel and find an airfield to divert into.
If anyone is considering fitting a LiPro I recommend sitting down first and working
out the electrical load factors first and then considering how much capacity
your would need to divert should you loose an alternator. It's done for IFR
capable aircraft as part of the design.
Fitting a LiPro is not all about weight saving and cranking capacity IMHO.

Hello,
Just for information
I put a lipo battery in my Europa...for better results I change my regulator
by a Silent Hektik. Like this: https://www.silent-hektik.de/UL_R_912.htm

thanks john.
Did you make any mods to the mounting system. The bendy steel bracket
things seem well ...bendy. That said I had mine mounted for the first 150
hours and they worked fine....it's the grass that Im worried about.
Now that you mention it I do have a split on the bottom seam which I have
to reinforce...

Unfortunately, Silent Hektik refuses to sell their items to UK residents. Pe

We have been using a EarthX lithium battery (ETX 680C) for several years. I wrote
an article for the Europa Flyer (EF82) concerning it. We load test it each
inspection and it will maintain rated voltage with a load of 10 amps for over
an hour. One feature of lithium batteries is that the voltage does not decay
as the battery discharges. It stays pretty constant but then falls off quickly.
We replaced the Ducatti regulator with one Jim built. A RV12 owner and electrical
engineer who researched many Ducatti failures developed this replacement.
It is essentially a clone of the Ducatti but with high quality components and
much larger heat sinks. Documentation and PC boards are available and the cost
is roughly $70.
B and C Aero now has a replacement for the Ducatti called AVC-1. The link to the
specifications is https://bandc.com/wp-content/uploads/2020/03/AVC1_Technical_Manual_RevIR_3-11-20.pdf
While not listed on their website yet, I believe the cost is $275.
We have always had our battery located on top of the foot well, even when we had
a lead acid battery. We really wanted to avoid long, heavy cable runs. There
are some loading situations where the CG is too far forward but we just use
a couple 1 gallon containers filled with water located in the rear for those
flights.

Hi Richard,
My building buddy has a Silent Hektik for sale. He might be willing to
send it to you (regardless of Brexit or else ;-).
Sorry, only picture I have :
If interested, do not hesitate to pm me.
FWIW
