Kerneels! Another cut and paste, you are outdoing yourself. If you expect answers to your questions then surley you should answer questions posed to you like with who and how long did you fly with and without a HS in a RAF?
Any how, I see you have highlighted some words; is this what you want me to substantiate?
“In my opinion” means In my opinion..
I have taken some exerpts from emails etc that I have received since doing some research.
Firstly when I started the research I was looking at the 130hp motor and two of the mods required an upgrade to the 160hp due to the weight increase – both thirsty and expensive.
Email exerpt in relation to power and speed settings:
“Bo's gyro is almost 15 MPH faster at the same engine RPM than my Sparrow Hawk.. and when your ready for an engine upgrade it's no different on the mountings”
Email exerpt re additional weight:
“If you have the soob 2.2 FI 130 hp engine on your RAF I would look in to how much additional weight the Bo Collins mod adds. The AAI mod needs the 165 hp 2.5 L to get off the ground when close to max gross weight on those high density altitude days”
Comment from a training instructor:
“With so much experience, it's very easy for instructors to instinctively compensate with minor adjustments that are beyond a students level of skill. Using a horizontal stabilizer will enable students to achieve good, safe, flying skills with less frustration and fewer hours of training. I see no reason for it to take 25 hours of training to fly a gyroplane”
...And 25 hours was too much with a standard RAF
- no wonder they had so many incidents.
Data from one type of MOD
Fuel Consumption: 6.5 gph at cruise RAF 6.5 but with mandatory engine upgrade and higher cruise speed
Dry Weight: 900 Ibs. RAF = 790
Useful Load: 600 Ibs. RAF =600
Gross Weight: 1,500 Ibs.RAF = 1390
Performance
Minimum Take-off Ground Roll: 100' RAF = 75’
Landing Roll: 0-30' RAF = 0-10'
Rate of Climb (ft./min.): 650' RAF = 1100 ft/min
Speed - Cruise: 70 to 75 mph RAF= 80 to 85mph
Other MODs do not have sufficient reliable published data but specs and performances are shared amongst interested parties.
Kerneels I am losing interest in this discussion partly because it is not a discussion and is turning into an insult blog. I see one comment has already been removed and the originator has nothing to add so perhaps we should terminate it..
I am however still interested in your motivation as your initial comment was not only opinionated but spoken/ typed with some passion. Perhaps you were a little over eager with your point of view?
I have a box file of research and it is not fair to dump it on this forum and nor is it fair to the HS supporters, as it would be very difficult to put everything into context.
It took me a long time to see the light but I leave you with one challenge: Go to Upington and I will pay for your flight in a RAF with a RAF instructor. You do not have to comment.
Experience is what you get when you don't get what you want.
