A quick note about the supplied control tubes for the tail. RE: Nothing sticks to them ie:C/A, epoxy etc.
It has been mentioned that 2mm heat shrink can help but it does not stick to the teflon tube even with CA applied. I confirmed this but found that if I give the teflon a light sanding before adding the CA I cannot get the heat shrink to move. Many are purchasing etched tubes for about $20

Topsky CG Location

Where are you folks setting your CG on the Topsky? I have my TS2 Disser around 68mm from the leading edge. Wondering if I should push it further back.

Hi Dave
Suggested CofG for my TS1 is 78>84mm, not sure if the Disser wing is the same but it should be close. Can't comment on where I like it as I just finished my build last night

Another one ready to fly

After weeks of slow building, my first DLG is ready to test fly. Many thanks to everyone here for the information I needed to complete this build. I can honestly say that without the info in this thread or linked from here I would not have finished with the same bird. I tend to make them strong and sturdy so I would have had a 20 oz DLG

Some details
AUW= 302g or about 10.65 oz
2s 300 mah lipo 17g, can be moved about 1.5" fore and aft (moves CofG from 78>82mm)
10g lead shot and epoxy in the nose
Max flaps is only 30 deg. (my first top drive) The ailerons are faced with bias ply F/G cloth and I have a patch of glass around the ail. horn. I read that top drive tends to cause delamination at the ail. horn and didn't want to go there.
I had mismatched C/F spars on the wings so I used the supplied C/F on top of the wing to try to hide this. I then used a heavier than supplied F/G cloth on the bottom of the wing. Hard points where installed along with the C/F tubes.
Boom was cut 2.5" and slotted for the fin. I could not get the C/F tow to stay in place so I used a 1/4" strip of C/F cloth and "clamped " it with stretch wrap to prevent the slot from growing.
Instructions say 644mm from wing TE to LE of fin, I am only 580mm
Everthing is set up on the TX as per info found here, all throws are per specs.

I will use the smaller 300mah at 17g and room to slide.Held in position and adjusted with 2 small blocks of foam.

I have since read 75>80mm and the HK file lists it at 70>80mm
I need to sort this out before I test fly.

EDIT: Topsoaring web site says 78>84mm

I have the viper and am settling at around the 79 / 80 point wich is working nicely, too far forward is easy to fly and set up but makes the model poor at indicating lift, too far back and i spend all my time recovering from stalls. It takes quite some time and calm days to get it all set up to your liking.

One of my NEW DSM44 servos has the jitters.
I noticed that when I apply very slight pressure on the aileron the servo jitters like mad.
Don't know if it could be fixed or not but not this one,as I willl have to grind it to dust to get it out.

Is this the Versus from HK ?

EDIT : Sorry, just looked further back to where you started posting and noticed you'd ordered from HK, so it is a Versus.

I'd say that the Versus is actually made by Topsky, they are way to similar

A guy who has both DLGs side by side offered his comparison here in the Versus thread. HK Versus came up on top, seems they make it a bit better.

Wow. Good service from Aloft Hobbies, Wayne is sending me a replacement servo no charge. I didn't even contact him to complain, he saw my post here about the jittering servo and is replacing it.

Thanks Wayne

Maiden Flight(s)

Finally got a chance to give it a try. This is my first DLG and my first launches.
Started with a couple javelin throws to check trims. After some small adjustments it was time to have a go at discus launches. I started with a couple 3/4 turn stationary throws which were almost vertical and not high enough to register on the "Howhigh". As I was throwing so high, I stopped using the launch preset (up ele.) and finally got a reading 47' Next toss was 62', then 90' The balance of the readings where 83',75' and 90' again.
It would have been very obvious to anyone watching that I didn't know what I was doing. Mixed in with the above "readings" were several vertical "loop" throws as well as one that came out of my hand early while I was thinking about my feet it was near horizontal but straight through the top of some 8' trees. The branches slowed it right down and turned it straight up at about 20' and it just missed the ground pulling full up ele. after the stall.
The wind picked up to about 10 kph so I packed it up as I didn't have a lot of room in a small school yard. Hope to get it out to the club before we freeze over.

In summary
I NEED A LOT OF PRACTICE !!!!
I had a blast!!!!!!!!!
I got sore finger tips.
