We're in grave danger of resurrecting an age old debate about Robinsons and their suitability for training here, but for the record I don't believe Robinsons are 'twitchy'. However, being a lightweight machine, the R22 is particularly susceptible to gusty wind conditions and very sensitive to W&B/control inputs. Remember, all helicopters are inherantly unstable and coming from a C150/152 or PA38, a plank driver will initially find any helicopter a handful by comparison.
I think the issue in this thread is more about the quality of rotary training and subsequent testing. The suggestion here is that if these were not delivered thoroughly and effectively, could this have been a contributory factor in this and the 6 or 7 other similar R44 incidents?
