ROC Hobby Critical Mass (High Speed Version) - ARTF
UK Delivery: Free
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 Motion RC 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. We will retain the normal speed Critical Mass as a product since not everyone needs extreme speeds. The high speed Critical Mass will absolutely leave 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 at Motion RC 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.
