Greetings from Seattle.
I've been fortunate to get my hands on an advance copy of the full-production Mini TopSky kit direct from the manufacturer. http://www.topsoaring.com/index_page0002.htm
It arrived via EMS yesterday. I was surprised by the weight of the box until I opened it and found it packed in a second box, surrounded wing core shucks and some interesting one-side veneer plywood.
The kit was well protected inside its own box and is very complete.
Component quality is very nice throughout. The wings are gorgeous, FG pod is nicely finished, it has a CF hatch that fits well, nice boom and very nice laser cut balsa for the tail group, even a plywood servo tray.
Complete accessories including FG control horns, Teflon control rod tubes, steel control rods, fiberglass, carbon fiber, hardware is complete - it even comes with some covering for the tail group.
The wings are beautifully made. My only add here will be to wipe a little finishing resin on the LE's to make them as smooth as the rest of the wing. Construction is flawless and the root areas are pre-finished to the correct dihedral.
There is a three-view drawing, but no instructions were included. Hopefully coming later or on-line for newer builders.
I'll post some photos as I progress with building. Plans are to keep it mainly stock, but since it came without instructions, who can blame me if things turn out a little different?
I'll mainly make a couple mod's to the tail group per my preferences:
Detachable horizontal stab and pull/spring controls rather than the included tubes and wires. No covering, just water based polyurethane for protection.
I'm also a CR2 battery fan, so I'll have to see how the gear layout might need to change as it is designed around a lighter LiPo pack.
I'm also going to build this as a SAL plane rather than DLG. Also a preference, but also due to a bad knee. So, someone else will have to comment on its full out launch height...
Stay tuned, it's going to be a short build. I basically only have to shape and finish the tails and start gluing the small number of parts together. Should be a breeze.

I'll be watching your progress. I have a TS-mini coming and I was thinking of going with the CR2 batteries and pull/spring as well. Do you think there would be any advantage with putting some lightening holes in the tail and covering with a light weight covering, such as Lightspan?
The published AUW of 135 grams seems ambitious (ie: unattainable).
thank you Chris,cheers
our test Mini Topsky bettary weight:
first one is 32 grams,nose is heavy.i added 1.5 grams extra weight on the tails,flew well
other one weight 19 grams,i added 5 grams nose weight flew well.(total weight 136 grams)
tails weight is about 7.5 grams.i think its important to build it lighter to make the tails weight lighter,but we have to find a balance piont between the strength&weight.
the tails 1 gram = 4 grams nose weight
