Mine is between 55-58mm from the leading edge. I also did use a 415g 3S lipo and didn't have a problem balancing at all.

Need to monitor my climbouts with the Eagletree so I can set my timer on my radio for a more accurate time to bring her down.

Mines @ 62 mm too, slope only. And i'm a little nose heavy and i like it that way

Been taking a break from gliders recently and spending more time on my helis after the crash.

New asw28 will be with me next week so it starts all over again, only problem now is i will be stuck with flying weekends only as its dark after work now

coyote 64-my 4s batteries arrived,and the 14x9.5 folder,connected it up in the cs discus-2.6 metre,and its power galore.Will hopefully get to fly it next weekend or the following weekend,depending on weather conditions.If l ever buy a asw 28 electric version,this is the combo l will go for,l still have the slope one.

Coyote 64-It took me three attempts to get the epoxy to finally start holding inside the fuselage,around the crack/break.Apply plenty and open the crack as wide as possible,and let it run in the inside,its a sticky,messy job,After two attempts l nearly gave up on it,but the third attempt worked.Micro balloons is good,as you mentioned.After all that cursing and swearing its worth it.regards damo

Just a little info the fuse's are all polyester resin so to ensure your repair holds it is better to use polyester on polyester as Epoxy although it looks stuck is not a structual bond and lets go quite quickly. I did a mod to all of them when I received the kits before attaching the rudder (but you can still do it) the rear spar of the fin is balsa cut carefully down either side (you want to put it back when finished)you can then get some glass reinforcement into the area concerned (a light spray with 3M77 helps to locate the glass). I used a small art brush to wet the glass out ( I used carbon on mine) and then used a peice of 5.0mm dowel to compact the resin and the glass , once cured replace the spar you cut out and your done.

Thanks steve for that, i was just thinking about strengthening my replacement 28!
This is going to be a even heavier ship now, i will also put some fiberglass tape around the leading edge of the vertical stab and around the sides and bottom of that area too.
Seemed to me thats where the gel coat likes to crack most.

You'll find also that the gel coat is actually just enamel paint

Coyote 64-I repaired my flying dream cs discus with epoxy,as it is a HIP fueslage,and not fibreglass,its PLASTIC(High impact plastic).Anyway,my slope asw 28 is still in pristine condition,in its box,it still has not been maidened yet-l have a ton of work on at the moment,so it will remain in its box.In future,if and when l need to repair, the asw 28,l will use polyester resin as steve pointed out.Have fun-damo

Actually, the fiberglass parts of the Aerofever/Flyfly/Hobbyking Asw 28 kits & similar are Vinylester, a resin produced by the esterification of an epoxy resin with an unsaturated monocarboxylic acid, What usually works well for repairs is to sand first around the damage, then apply a coat of thin CA glue, and then use epoxy for the repair. The CA works as a sort of bonding agent in this case.

Are you sure ? I use Vinylester on my moulds and you can tell the difference by simply sanding, the smell is without doubt poly not Vinyl, however using Vinylester if not slightly more expensive than poly will adhere structurally with a positive bond without any problem

Martin,
put a T/edge Thickness of reflex in the ailerons and reduce the elevator throw slightly which will help overcome the tip stall by forcing some washout into the wing. You may even move the CG back just a smidge.
