The Diana 2 and the GP15 are probably the most splendid single-seat competition gliders currently on the market.
The Royal Model Diana 2 (SZD-56-2) seemed perfect. Just under 4 meters at 3.75m, allowing me to easily transport it (wings below 1.9M – detachable winglets), the cool look full gfk and carbon dbox in the wings and allowing me to enhance and reinforce the build to fit me needs.
First impression, surfaces are well finished, no gelcoat glitch, carbon layered from the wing to the tail, provided hardware joiner could be okay for a basic build. Wings internal is fine and everything seems in order (checked with my endoscopic camera) – wing spar properly glued on the whole length, good epoxy/filler joint.
For the record, I tried first to order a “deluxe version full carbon” of this RM Diana 2 from the only reseller providing it (carbon reinforced, …) and I never got it after months and three rescheduling. In February, I felt back to classic resellers and got the model in less than a week. Thank you Weymuller.fr and Royal Model.
In the end, I am pretty happy to have a vanilla version. It is perfectly eligible to modifications and I was able to enhance what was missing, and I guess better than the phantomatic “deluxe version full carbon”.
Here are my modifications:
Carbon reinforced fuselage from wing to nose.
Carbon reinforced servo skin/surface – I only did the elevator… but I regret. If you read this, you should do the aileron and flaps also.
rudder internal structure refactoring for stiffness
Hinge gap epoxy/microballoons sealing (using curved klapton tape as mold)
light carbon/steel wing joiner
seamless aileron/flap to servo – no external horn.
