Gyros,
are not any more dangerous than any other aircraft.
ALL depends on maintenance and proficiency (professional initial training/rating - frequent refreshers until experienced to all limits - maintaining proficiency).
 
Also, if an aircraft is successful in sales, that aircraft is prone to show up in the statistics eventually as high numbers are flown (If there are 30M Fords and only 3K Lexus out there, Fords will lead the accident statistics...)
 
A sample is Robinson helicopters (statistically the safest helicopter, lots of accidents but everyone flies them and can afford them, although not everyone SHOULD fly them, mainly it is pilot error...)
 
Same goes for the Mitsubishi MU-2 series - 3 times certified, nothing wrong with the airplane, actually one of the most robust airframes ever made, but pilots are skipping proper training (Beech Bonanza syndrome, but not US-designed/only manufactured, so it is the root of all evil...). Unfortunately this plane does not legally need a type-rating although it needs to be flown (and is no more complex or difficult than...) a Lear-Jet, Citation X, or any high-performance speed demon. To bad it has props on the turbines which with its weight makes it a light twin and only needs a twin rating on any twin....
 
I wonder if the friend mentioned got enough instruction and if he thoroughly understood Gyros. I get some airplane pilots at times who want to go for the helicopter, but do not like the high cost of training - they are dissapointed when I turn them down, as they cannot cut corners with me...
 
Certainly there are more lively gyros than others (....or more boring ones than others) I doubt that any "bad" gyro would last in the market....
 
Some people drive Porsches/Ferraris/Corvettes and shouldn't even drive a Chevy Metro....
 
Just make sure the machine is healthy and you get thoroughly trained - rotorcraft need no control movements, just think about applying pressure no more.
If you ever got a ride in a Glassair III - what that bird needs for smooth control at speed is all a Rotorcraft needs at all times...

Rusty, here is a picture of the vents, both have tape on them, one is on the oil fill tube and the second one is to the right and comes out of the center rotor housing. 
 
Hi John,
 
Both of those are open to the crankcase, so you can use one for the vent, and just stick a rubber cap over the other one.   
 
Be careful with the gyro, we lost a good friend here, summer before last on his 3rd solo landing.  On final he apparently unloaded the disc at 80 feet AGL.   
 
Sorry to hear that, but unfortunately, there are a number of unsafe gyros out there, and this is a reasonably common story.  I've done enough research to know which ones are the most stable, and will limit myself to those models.  Truth be told gyros "can" be one of the safest flying machines there is, and that's one of the reasons I'm attracted to them for the single rotor testing.  
 
Cheers,
Rusty (haven't flown the RV-8 in weeks...)
