Back to the original post.... I was the pilot of said Rotax powered aircraft that got grounded at William Creek, upon landing in William Creek I discovered coolant was pissing out everywhere, we let the engine cool down then did some further investigations to find a split in the radiator, a new radiator was flown up and the aircraft flew back to Gawler yesterday nearly two weeks after it departed Gawler for William Creek. I am very grateful for the friendship us aviators form together, without it I would have been sitting in William Creek twiddling my thumbs for two week waiting for a new radiator. On the whole Jab vs Rotax thing they are both very good engines, they both have had and still do have their issues but I will happily fly an aircraft with either engine. One pilot at Gawler has said they don't want to fly that aircraft anymore because of the radiator, if I was to stop flying an aircraft every time it had an issue there would be none left to fly in, every plane has its issues throughout its lifetime and I'm sure it wont be the last one for this aircraft but am I going to fly it again? YUP.
