Willie,
In my XS Trigear G-CBYN I have 450 hours behind a non induction heated 912S
and 100 hours on one with a coolant heated connector on the manifold side of
the carb as supplied by Skydrive.
The former has regularily given a burble as ice is swallowed from each carb.
Before the burble the effect of the ice on performance is unnoticeable.
The twitches generated on me are not.
With the heater I have never had a suggestion of the burble.
The heating is effective and I am sticking with it on the new aircraft.
Installation is simple but moves the intake plenum chamber rearwards about
15mm.
The inspector did not consider it as a mod and just signed up the logbook.

<willie.harrison@xxxxxxxxxxxxxxxx>
Folks, 2 questions:
1. What experience does anyone have of electric or coolant-based carb
heaters for Rotax engines?
2. Can anyone tell me whether either of these is regarded as a standard
mod by the LAA?
Many thanks in advance.
