Its a big hit but what price safety? As with the fuel bladders it is a small price to pay for your head or, more important, those of your innocent passengers.
And how many more "as with" AD's before the substantial sums involved mean it was false economy to not buy a better-quality Helicopter in the first place?
I'll bet there was a very good reason that Denis Kenyon stuck with Enstrom
, and so many Ex-Robbo owners have not bought another.
It is, what it is, -a very cheap entry to Rotary flightbut the hidden cost of lifting the safety-level to an acceptable level, means you may as well have enjoyed the safety, security and comfort of a more airworthy aircraft from the get-go.....and before anyone argues about the Robbo's airworthiness, why are you wasting money on bladders and blades and...... if the thing is serviceable anyway?
Never flown in one and no intention to.
