VIPER™

Based on the classic Estes EAC Viper Model Rocket Kit

The VIPER™ is an upscale based on the Estes Aerospace Club (EAC) Viper, and was co-developed with QBAR Team Member Bob Cox. The VIPER is the first of QModeling's top quality sports class model rockets designed and produced under our QBAR Team Program. The QBAR Team Program is a chance for a selected customer to become part of the QModeling Development Team and help design, implement, and test a new Metro Retro Series kit.

Bob was a perfect choice to help us unveil our QBAR Team Program. His vast model rocketry experience and concise constructive feedback enabled us not only to produce the VIPER but also help us refine the entire QBAR Team Program.

Thanks Bob!

The QBAR Team has created a MEGA BT-80 version of the classic that enables the use of E or F size 24mm rocket motors for impressively powerful launches. The VIPER is a 2.66:1 MEGA scale of the original EAC Viper making it over 36 inches tall. Combined with QModeling's high quality laser cut parts and renowned easy step-by-step instructions your own VIPER could be streaking across the sky in no time.

QModeling's VIPER comes with a their unique Engine Mount eliminating annoying Primary Fin alignment problems while providing a very robust easy to build design. The kit includes QModeling's BT-80-OGIVE Nose Cone produced from their high quality nose cone liquid plastic process. The kit comes with a full set of unique RMS upscale decals as well as an interlocking Primary Fin design for strength and easy construction. An extra Centering Ring is provided to form a parachute compartment enabling better control of the CG and recovery system deployment. The VIPER also comes with QModeling's unique retractable engine hook design.

Like the other RMS kits, QModeling has broken the deployment barrier by offering a wad-less high performance Recovery System based on a partnership with Top Flight Recovery. It consists of a 30” Octagon, Thin Mil, Ripstop Nylon Parachute with sewn in 24” Nylon shroud lines, Nomex 9” x 9” Heat Shield Parachute Protector, 9’ Kevlar Shock Cord, and a Snap Swivel. Now there is no need to search out any after market recovery system components, because QModeling builds top quality into all aspects of their kits.
