Just purchased a new unbuilt ARF KIT, S2G-ASW 27,4.2 METRE WINGSPAN.It has flaps,double height 370mm Multiplex spoilers installed,ailerons,elevator and rudder.Total of 5 channels.S2G are no longer,RKM Top Model bought them out.It has foam core wings,sheeted with obechi,oracover over the sheeting..Airfoil is HQ 2513,.Wing rod is steel pipe-18mm in diameter.The ASW 27 will join my other big gliders-DG 808S-4 Metre,PIK 20-3.75 Metre,DISCUS 711-4 Metre,and will be the last addition to the fleet.I will commence work on the ASW 27 soon,there wont be a build log,but will post some pics once its completed.......Updated-16/1/2011-Its completed......Flying weight is 5.550 kg-27.5 oz/sq foot wing loading. NEW-Wing rod is 18 mm diameter aluminium bar,to replace the bent 18mm diameter steel pipe supplied.Extra weight comes from strenghthening the cockpit,wing fairings of fueslage and tail fin and base of fin with fibreglass-the fueslage was like an eggshell,you could twist and buckle it with hardly any pressure applied,Hitec HS 225 MG servos control the rudder and elevator,both located in the fin-direct no slop linkage with accurate centreing.HS 82 MG servos control spoilers/ailerons and flaps.Overall opinion-A tad on the heavy side,at 5.550 kg,wings have no spars,but are glassed,then covered in obechi.There will be alot of outer wing flex as a result.The wing tubes were also epoxied inside the wings,this added weight also-but had to be done-S2G did not epoxy the wing tubes in the wings-which would of resulted in delamination of the obechi and wing root area, as read on rc universe forum.The extra weight means it will need more wind/lift to safely keep above the slope-20 plus knot winds.It will also fly quicker,because of the increased wing loading/weight gain.Well,its completed,after 40 hours work,Will post a pic soon,-

I am awaiting delivery for a Discus 711-4 meter semi-scale glider,via EMS airfreight-ETA-12 days.This glider is cheap,but has 440mm spoilers pre-installed,and it will be a slope only model.I am going to strengthen the entire cockpit,wheel cavity area with epoxy resin and woven cloth,and install a dubro 2.75 inch fixed front wheel and a dubro tail wheel-25 mm diameter.Hitec HS-225 MG and Hitec HS-82 MG servos will be used.I will post some pictures once it arrives,it will be built during the winter months-year 2011.regards damoUPDATED-9/12/2010-IT ARRIVED TODAY-Everything is okay,nothing was damaged in transit,the spoilers are free working and sit flush to the top of the wing,in closed position.The fueslage is thin,l have removed all the cockpit formers already and the entire cockpit will be glassed from the nose to the trailing edge,the formers will be epoxied back in,etc,after glassing.OVERALL-Happy with it,big straight wings,big wing area,no warps,spoilers are great,the fueslage is the only negative item-too light a lay up,this will be rectified by a proper lay-up.Other mods will include tailplane mod and wheels to be fitted,nothing to hard,looking forward to working on it.I will post some pics when l get around to it.regards damoCompleted this model just before christmas 2010

Semi-scale Flyfly Condor evo magic 4-well made arf kit-straight fin,wings align perfectly with the fueslage.I highly recommend this glider,big wing area,well made,high lift- flat bottom eppler 205 airfoil,and a good buy at $300 Australian dollars delivered.

The final flying weight is 3913 grams,wing loading 22.98 oz/sq foot.Apparently the roll rate of the DG 808S is mediocre,so coupled ailerons and rudder is what l have got,with full rudder throw.I have also worked out a better throwing technique using two hands,my left hand will below the cockpit area and my right hand at the base of the fin.With a strap for the transmitter,it leaves both hands free,it should be okay to launch by myself,using this method.

Everything is in the fueslage box required for flying-extra ballast,CF rod,electrical tape for the winglets,scissors,rubber bands for the wings,tailplane,winglets.I also added cardboard chocks to stop the fueslage sliding from side to side.The wing boxes only cost $10 including a reel of tape,and they are strong-cheap & practical.They fit in on an angle between the seats of my small 4 door sedan,and by moving the passenger seat forward the fueslage box fits no problem,and by putting the back seat down also.The transmitter and 12 volt swallow charger go in a separate flight case,and l can charge transmitter and receiver batteries at the slope.It was worth spending the extra time making these boxes, and it only cost $10 for everything,by using the original kit box and outer as well.I can now load the car in less than five minutes,and charge batteries after flying for one hour.I am using 2100 mah batteries for the receiver-varta fast charge-15 minutes-4.8 volt battery pack.I built a charger facility so l can charge 8 varta batteries at once,as my futaba 4exa uses the varta 1.2 volt batteries also.

The rain has not stopped-just balanced, so l decided to take a quick pic whilst the wings are still on.

This model flies well,and l use a y-lead coupled with ailerons and rudder to make it turn better.Light as a feather-750 grams total with lipol 1300 mah 11.1 volt battery,used for thermal mainly but have used it on the slope and its a real joy-just add extra ballast-handles 15-20 knots no problem.Looks good in the air,after all it is made entirely of foam,so doesnt look as good as the flyflyhobby Dg 1000-2.6 metre on the ground.Wingspan is 2 metres.Have flown this model many times,and have had no problems with it.
