Vin,
As Michel has indicated, the new "ARF Plus" kits are being manufactured using new technology and materials. Using higher quality resin and cloth in addition to entirely new mold techniques, Skymaster has reduced the weight substantially in their new airframes. Live hinging, pre-installed gear doors, tube spar system, bearing stab mounts and dual engine mounts (on some airframes) are just a few of the outstanding upgrades in the Skymaster lineup. Stay tuned, lots more info coming
