After winning multiple RES competitions with the Topaz S, Skip re-designed the model to further increase it's competitiveness. To achieve these witnessed improvements, the center section has been increased by 4", the front pod has been modified into a drooping nose which improves aerodynamics and the airframe has been reinforced with more carbon thus making this the most efficient and competitive Topaz to date. The Topaz S V2 Electric uses the same wings as the Topaz S V2, but has a special designed electric fuse that accepts a wide range of power systems.

The wings are made of carbon laminated balsa ribs with a moulded Kevlar/carbon leading edge. This provides an extremely strong wing that can handle the hardest of launches. The fuse is moulded of Kevlar/carbon  with a 2.4 nose, and comes with a servo tray and ballast tube. The Topaz SV2 still arrives at a lean 35oz with out the motor installed after these improvements.

Here are key highlights from the new design:

1. More aerodynamic fuselage...of course 2.4 friendly!
2. 4 inches more span
3. Cleaner spoiler construction/ composite/ balsa
4. Triple carbon laminated leading edge on vertical fin and  horizontal stab
5. MUCH IMPROVED CONSTRUCTION OVER ORIGINAL TOPAZ
6. Carbon leading edge under Kevlar slotted into carbon capped ribs
7. Ready to fly weight  35 oz!!!!!
