The Tracer (T2) is all finished and ready to maiden. It took roughly 6 hours to complete the kit including a fair bit of thinking and covering time. The balanced AUW is 570 grams (20.1oz). This includes 4 x 14g servo's. So using 9g servo's would take you well under 20oz which is pretty good. It also took 17g (0.6oz) of lead in the nose to balance on the advised COG. Here are a couple of photo's of the linkages

The two halves of the Tracer now make a whole. Prior to gluing together I rebated out some EPP just to take a little weight out of the boom. I used Latex to glue the two fuse halves together. It's quite runny stuff so I dripped it and spread it out with a brush, both halves received the same treatment and once dried clear I slapped them together, gave a gentle squeeze and the joint was securely made. All together with the aileron extension leads just protruding out of the fuse on each side. Then I started to router out the wind servo apertures after which the iron made it's debut and the covering has started in ernest.

The weeks previous forecasts leading up to the 2nd IOM SWDCS (south west district championship series) at Yeovil had varied form + 15mph and heavy rain to -5mph and wall to wall sunshine. In the end the wind never rose above 5mph and the sun never really shone through the clouds. It did however always threatened to rain with a few very light showers at times.
Sixteen Competitors arrived at the lake and racing started just before 10.30. There appeared to be more wind on the opposite side of the lake as the control and racing area was in the lee of the steep tree lined railway embankment. What little wind there was did generally come from a North West direction so a triangular course was laid and remained un-altered for the rest of the day. At the start of the event there was a slight bias to start nearest the bank. This was only due to the fact that it was approx 3 boat lengths nearer the windward mark. As the day progressed so the wind filled in slightly, probably making 5mph in the gusts, this slight change made for a more equal and fairer start line as the stronger wind was found in the middle of the course making up for the extra distance to travel.
I would imagine that at least 12 races were run with a short break before lunch and another small break prior to the last 3-4 races. No one skipper appeared to be taking the majority of the bullets, in fact I doubt if anybody had more than 2 bullets to their name. Although, to my mind the one person who managed to...Continue Reading

Build an EPP glider that is! So I've built a couple of EPP wings but that's different, they aren't real planes. The build is that simple that no instructions come with the kit and the info on the web is..........lets just say it isn't worth the cost to print off. The only information which I can see will be of any use is the COG.
I thought I'd start by deciding on the location of the servo's, bearing in mind I want to keep them well forward but not enough to interfere with the battery pack. Servo apertures are now cut out, battery and rx locations sorted. I have kept the rx well above the fuse carbon tube recess. Both fuse halves have been rebated and chases cut for cabling. I have rebated the AMT control horn into the fuse to allow full movement which would have been difficult if the clevis protruded outside of the fuse. Then more chasing into the fuse to take the rudder clevis & control rod. Note both snakes run into the carbon reinforcement tube towards the servo's.
Magnets are fastened into the fuse wing root supports which have then been glued into the preformed fuse rebates.
