To my utter surprise and horror, the collective servo frame supplied with the kit turned out to be not solid but filled with light filament structure. This, of course, no sooner than it was glued in for eternity and I tried to drill holes for the servo bolts. The self-cutting threads will never get sufficient grip in this stuff. But this time I have more luck than brains.

There just enough room between the floor and the frame for an M2 threaded brass sleeve. The servo lugs are 1.8 mm and need some carefull rework to allow for the new M2x8 screws.

Note that the servos 1 (elevator) and 2 (rudder) are slanted outwards to clear the ailerons‘ steering rods.


Drilling holes in the tail boom is not a good idea, especially behind the trailing edge of the wing. This is a heavily strained area during discus-style launches. Care must be taken to avoid creating a weak spot here.

My Voltcraft BS-17 endoscopic USB camera comes in handy for working inside the narrow fuselage far behind the cockpit opening. But still, it takes a gifted modeller to accomplish the mission with the resin sticking to the sidewalls rather than smudging the camera’s lens.


Standard receiver for my DLGs is Jeti’s R5L EX. To celebrate today’s successful exorcism of the White House (08.11.2020, Biden 290, Trump 214), I’ll suspend my personal embargo and go for Amercian produce this time. A Spektrum AR617T 6-channel receiver with telemetry and SAFE stabilizer is it going to be.

4.5 grams of bulky plastic casing are removed and replaced by a piece of clear shrinking tube.
