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 succesful 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. However the years had been hard on the Sea Fury and its utility was limited to a "one week a year" mission. There was much discussion within the Dwelle family on the future of the Sea Fury but a phone call in Dec 2006 set the course. The 4,200 HP hybrid racing engine on Critical Mass was to be sold to the new owner of Unlimited Racing Icon "Rare Bear". Within a month, Critical Mass's clipped outer wing panels were traded to unlimited heavyweight "September Fury" for that racer's spare set of stock wings. The path was set, Critical Mass was to be restored back to stock!

We felt the Critical Mass was deserving of a high speed power plant to give it the performance many are looking for. The Critical Mass was already one of the favorite planes around but now it is even better. We added a larger 3648-770Kv motor, 70A ESC, and 9g metal gear servos. In addition the plane now runs on a 4 cell LiPo. The Critical Mass can now reach speeds of 90Mph and has unlimited vertical. The critical Mass still retains the amazing flight characteristics it has become known for. Landings are still slow and very predictable. It is a true joy to fly.

Don't forget about the great features that made this plane popular in the first place. It still has split flaps, servoless electric retracts, and fantastic good looks. Unlike many stock planes, this one is not underpowered at all. In fact, this plane may be too fast for some. The high speed Critical Mass will absolutely leave lesser planes in the dust. The high speed version has the same strong EPO foam construction and retains the nylon hinges for the split flaps. The retracts have proven very durable on the original Critical Mass so the same retracts with metal trunnions have been used again. The same upgraded problem free paint has been used to match the later versions of the regular speed Critical Mass. We think this is one of the most durable, most fun, best built planes on the market. Like all RocHobby planes, this one is made by FMS.
