Hello Cliff,
Yeah. Paid by Paypal on the 5th Nov. On the 15th i emailed Barry to ask for a date that the canopy was sent but haven't heard anything back from him yet. I'm looking forward to seeing it finished as well. I have the C/G all sorted. Radio is all programmed up. Paint work is curing nicely. Weather is warming up, 31c yesterday at our flying field. I don't mind the waiting time as it gives me an opportunity to tidy up the shed a little before messing it all up again with another build. First up will be a storage/travelling box for the PWS and then a non scale Leprechaun glider which i will electrify.
Cheers
Lawrie.

Here are a few more photos to bring the build almost to the finish line. The Canopy was the job to finish off. Thank you to Cliff and Barry for a wonderful job. I would like to thank Stuart Ward from NZ for his concern about the red snaky tubes visible in the early stages of the fuselage construction. They have served their purpose of guiding the pull-pull wires through the fuse up to the rudder servo and have now been removed. I have to say that I have really enjoyed this build. In the main it has gone together very well. Parts were cut very nicely and slotted together with a minimum of sanding and filing. The gull wing construction was a first for me and i'm hoping I have engineered the join in the wings sufficiently. I feel confident they will be good enough. It wont be a speed machine and hopefully it wont ever be doing snap rolls and loops.
I am hoping to fly it this weekend coming. Its 41C outside right now and a fair bit warmer in the shed so its not real conducive to modelling at the moment. Anyway i am hoping we can get an early start on Sunday with the aerotowing and get in a couple of flights before it warms up too much.
I'll keep you posted.
Lawrie.

Well finally after nearly 9 months of fun and games the PWS takes to the air and goes up where she belongs. After putting it together and checking everything to make sure the control surfaces were going in the right directions, for about the hundredth time, did a range check, the tug pilot was ready so it was out to the flight line, hook up the tow line and before I knew what was happening, it was away. It was airborne after about 8 metres and going up like it was on rails. It felt rock solid on the tow and all I had to do was stand there and watch and let the tug do its work. At about 250 metres I released the tow line and straight away I could see it start to slow down so pushed in a little down to pick up the speed and then pushed in 5 clicks of down trim and that was it. She floats around very nicely, will pick up speed if you need it and will slow down without any sign of tip stalling. Control surfaces are working just fine. Ailerons are very positive, they are very big, and go up 25mm with 50% diff and 50% expo. Elevator is nice and positive. It goes up 60mm, down 50mm with 50% expo. Rudder is 60mm left and right with 50% expo and mixed with a switch to ailerons to 70%.
It doesn't take too long to assemble, hooking the wings together is the fiddley bit, but it can be ready to fly in about 10-12 minutes which is fine by me.
I had thought about making up a small 2 wheel dolly for it to take off on but it was not needed in the end. The tug with a DA 120 up front had plenty of power to haul her up off the ground.
Landing was long and flat. it does float on, the air brakes do slow it up but not in a great hurry so care is needed. If you use down elevator to lose height you will also pick up speed and float on even more. I was landing into a light cross wind which doesn't help to slow things down so a head wind would the preference but not an option on the day because our cross strip, where the wind was is quite a bit shorter with a steeper approach. After the first landing and carrying back to the pits, it does take 2 people to carry with hands under the join in the 2 wing panels, it does weigh 12 kgs and is quite a lump to try and carry on your own, any way I sat down with a bottle water and I don't think I moved for about an hour, just sat with a silly grin on my face whilst trying to analyse the flight with the tug pilot and our spotters. The second flight was more of the same but maybe a few minutes longer. After only 2 flights I don't feel the need to change any of the control throws or the C-G. It was thought to be slightly nose heavy at 140mm back from the leading edge but for now it will remain there till I get a few more flights under my belt. 2 flights were enough for me on its first outing. It was very hot at 35c and the cross wind was getting stronger so I packed it away in the van and sat some with that grin.
Thank you to Cliff, Vince and Brian for your kind words.
That's it from me for now.
Cheers, Happy days.
Lawrie.
