As you all know the Twin competed in the Chinchilla Easter comps. Following is a brief outline on the twins performance.

Firstly a big thanks to Brian & Anne who's administration roles made the whole week work brilliantly, there is no doubt their contribution is what made the competition possible. David Higgs and Mick Maloney had the unenviable task each night ensuring the scoring was correct as well as helping many pilots submit their logs. Neil Muspratt spent all of his time at the airfield standing behind the bar serving. Garrett Russell also put in a big week keeping the flight line under control. Thanks to you all.
Practice day. Karl Bodie. 209km at 83km/hr total flight time 3hr03min Low point around 1500' and a couple of 2000' points. Run to finish line at 110 knots.
Day one. Alan Graham. 248km at 81 km/hr 3hr 04min on task 3hr57min total flight time. A low point of around 1000' near the Bunya Mountains. Another couple of low spots below 1500 feet had us well practiced in paddock selection. The inbound call to Chinchilla 20km from the airfield at 3500 feet above ground made for a quiet glide to the finish line.
Day two. Nathan Cornwell. _km at _km/hr. 1hr 43 min duration. After struggling for height before the start we finally made a start at about 3000' AGL. Gliding toward Miles we passed 2 single seaters returning home. Another weak thermal up to 3000' had us back on track. However the weak conditions and low heights convinced me to return to Chinchilla, where gravity eventually won. We did score, 17km. Mick Maloney and I still managed to retrieve a Twin. The Bundaberg Twin outlanded a few km from the airfield.
 
Day Three. Neil Muspratt. 210km at 85 km/hr 2hr 20min on task 2hr 46min total. On task we had a bit of a struggle early getting away from 1200' at one stage. We then had a great run with strong thermals until about 30km from home we had to take a weak thermal under an overcast sky to make final glide. That was our 2nd flight. The first flight saw us being launched first, struggling to get away. After trying to gain height in vein for half an hour at 1000' or less we gave in and joined the end of the queue for a relight. 
 
Day four. Lindsay Mitchell.  This was going to be an interesting flight right from when Lindsay's phone started ringing as we commenced the ground run. 256km at ....... oops we outlanded.  Only about 10 km from the airfield. We had had a great run, strong thermals, long glides 20km or more without thermalling. Just past Condamine we had a discussion, disagreement on which way we should continue. I won, taking us another 10km further from Chinchilla. What neither of us knew was that the battery had about another 20 minutes of power left.  So with 40km still to go our varios fell silent. We were only about 500' too low to make it back to the airfield. A nice paddock was selected, we parked right next to Pierce Mitchell's Mosquito. Lindsay did mention something about 'if only we hadn't flown so far from Chinchilla', but I wasn't listening.
 
Day five. Simon Descovich 4hr 36min for 4h on task covering 296km at 73km/hr. Best flight of the comp. The first 150km gave us great streeting and strong thermals. Ask Simon what it feels like to pass up a 5 knot thermal and he'll no doubt tell you it was nothing compared to flying straight through 10 knot thermals because we had enough height. Averaging 100km/hr gave us a huge amount of confidence turning back toward Chinchilla, 100km and one hour to go. We then fell to a great looking paddock and checked it out from 1500'. A climb back to near cloud-base renewed the confidence of penetrating into the 20 knot headwind. Then the battery went dead. 60km from home 4000' No varios, again. We continued on, trying to feel the thermals when we spotted someone thermalling. As soon as we got to their thermal they left. We proceeded to try and feel our way up the thermal when we were joined by David Higgs in the Gympie K21, the Boonah Twin joined us, then more gliders till there were six gliders all in our thermal. We followed them to the next thermal and then safely made it home.
 
5 flights covered 1219km in 15 hours.
