The RocHobby Critical Mass has become one of our favorite planes. This plane not only looks fantastic but it a true joy to fly. We think you will enjoy the split flaps, servoless electric retracts, and great all around flight characteristics. Unlike many stock planes, this one is not underpowered and has decent vertical. The Critical Mass is very well mannered and capable of aerobatics that would leave lesser planes in the dust. . The combination of a powerful 3648-KV770 motor and 14.8V 2200 mAh battery allow this Sport Racer to reach speeds in excess of 85 MPH with a 4 blade prop. Clean lines, exceptional detail and simple assembly make this model a top choice among intermediate and advance sport flyers. This plane is made from EPO foam for maximum strength and durability. Speaking of durability, the split flaps have nylon hinges and the retracts have metal trunnions. It is one of the most durable and best built planes we have flown lately. Own a part of Reno Racing history with this high performance scale radio control model. 

Critical Mass History

The Dwelle family's 1950 Hawker Sea Fury T.Mk.20 known as "Critical Mass" has been a regular on the Reno Air Racing scene since 1987.  It was very successful in the racing role; ex Vietnam Skyraider pilot and family patriarch Tom Dwelle finished a best of 2nd place in the Reno Unlimited Gold class. This Sea Fury is somewhat unique in that it was originally built as a two seat, dual-control trainer before the front cockpit was removed to support its racing role.  As a dual control trainer, it would be one of only seven left in the world and make an ideal stable mate for the Dwelle's pair of North American T-6's.
