Re: Super Sport empty weight
On the subject of weight; for those who might be considering the 912iS
engine, my super sport with 912iS has an empty weight of 820.4 lb.
It has GLASS PANEL, 1 COM, XPNDR, ADS-B, INTERCOM, ELT, 2 GPS, and
a extra Aero-volts 12 cell battery used as a dedicated engine computer
back-up. It is my understanding that the 912iS weighs about 40 lb more
than the carb equipped 912. I am using a tricycle gear at present.

The weight and balance term is "Empty weight" and should include only the unusable fuel.
Re: Super Sport empty weight
I stand corrected, basic empty weight is 820.4.
Re: Super Sport empty weight
Neville,
Your 40 lbs more weight comment sure caught my attention :eek: as I plan to use the iS engine also. Checking the Rotax site, they list 124.5 lbs for the ULS and 140.2 lbs for the injected iS engine. A 15.7 lb difference, which is more palatable to me.
Re: Super Sport empty weight
From what I've researched, the 15.7 Lb is base engine weight difference and does not include the external component changes/weights: Different air intake, different engine mount, different dual electric fuel pumps or the ECU.
From what I've been able to gather, the total weight change should be in the 20 to 22 Lb. range. All in all, still not very significant when you consider the fuel burn advantage, no carb icing and simpler control - other than the price of course!
The 40 Lb difference mentioned might be closer when comparing to an 80hp 912UL.

Re: Super Sport empty weight
My 40lb statement was based on a casual conversation back when the 912Is was introduced. I agree that 20lb more is a lot closer. I do know
that the figure does not include muffler or fuel system components
not supplied with engine. However, I am very pleased with the engine
performance even without the Sport upgrade (on order). Because of
the computer control it is a joy to start at any temperature and restarting
when engine is warm. One down side is the cost of a BUD's adaptor
to check engine performance/faults ( $900.00).
