Update
Saga of the ICOM A20 repair is Icelandic in scale... Local LAME had a go then avionics dude from Bankstown. Then radio taken away to ICOM skunk works, "repaired", brought back, reinstalled ==> no different..... More farting around for weeks on end...... My new aeroplane sitting in club hangar unusable....... Eventually I bit the bullet and bought a brand new Garmin GTR2000 ( I think it was?). Installed quickly and works perfectly. Whew! Cost me nearly $3000 all up + just received a $550 bill for repair of ICOM which was not repaired and currently not in my possession. LAME told me a bit later that he has had similar trouble with other ICOM A20s and would never recommend one.
THEN, after 10 weeks, I could finish aircraft familiarisation flights and do what my licence says...hurrah!
Learning curve: Rotax hardly ever starts first time like the Jab engine used to: choke toggle turns itself off with vibration. Carb heat toggle a lot more effective at dropping rpm than in the Jab. Might be a good thing? Temperature gauges hardly seem to get above their lower readings at this time of year. Obviously the Rotax rpm nearly double the Jab. More like a Japanese motorcycle engine that I am familiar with.
Leaps off tarmac nearly straight away. Climbs 1000 fpm easily at 50kt and 5200rpm. Had trouble at first with flaps getting "stuck on" but I was holding the release button in. Just press the button once and its OK. Noticed that rpm tends to creep up after its set at 4800.
She's a bit slow in the circuit and long trips will be able to be savoured :-) Suits me perfectly! As a 60 hour pilot I'm not really qualified to make definitive statements but seems to be very forgiving and easy to fly. Taking photos is possible with hands off stick for a few seconds but I have since bought a GoPro.
Have pretty much explored the territory allowed by restricted pilots certificate, time to get into the X-C training and sample a few $100 hamburgers!
