I agree,centre of pressure is detemined by airframe attitude and speed,not power.Control stick friction can inhibit coupling between airframe and rotor motions in an airframe,destabilising the whole gyro .The gyro should self stabilise.Interesting that you also experienced this in straight and level...

Yes, in the cruise, I've had the violent forward and aft what felt like rotor flap before. Very scary when it happens. Goes away if you reduce power immediately. My previous VPM M16 we converted to a Rotax 914 did it. Horrible. Glen,do you think it is power problem?Did it ever happen again? Did you...

Anyone ever experienced a rotor flap while flying straight and level? SCARY PILOT Hi, I support Greg's explanation. The higher the DA the faster the rotor will spin. The faster the rotor spin the higher the centrifugal force, hence less chance of rotor flap, as the blades becomes even more rigid. A...

The database of RAFSA was comprehensive and complete enough for Eben to determine the manufacturer and the date of manufacture of the set of rotors bought by Jozef.Congratulations on your system RAFSA.Your assistance and quick response is commendable.ROTORS TO BE SCRAPPED.

Waardeer dankie Eben.Sal Jozef vra om jou direk te kontak

Die eienaar is Jozef Hugo.maar ek het nie die mandaat om namens hom te praat nie.Met die inligting wat ek het sal dit nou weer n kan wurms oopmaak wat die gyro gemeenskap nie nodig het nie.Die stel rotors het blykbaar ook n balansering nodig.

Thinus,hierdie projek het tot stilstand gekom,maar nie as gevolg van die engine nie.Iemand het aan die eienaar n stel RAF rotors verkoop en nou wil die eienaar nie daarmee vlieg nie vanwee die veiligheids vraag teken.Hiedie gyro is in pragtige kondisie,maar die eienaar het alreeds te veel geld gespa...

That is exactly the problem CrazyDoc.Getting all the gyro pilots together at the same time is almost impossible.Much of the animosity around is because of a lack of communication.We do the proverbial thing and stick our heads in the sand,hoping the problems will go away.Carnavon was a a good example...

LOVE IT.Now we need a 130Hp plant.
Francois Strydom

Details are very sketchy,but i sincerely hope that the extra weight of this powerplant was added to the engine casings for reinforcing.As it was the casings were clapping hands and transfer of material between the two casings are a common phenomenon.130Hp with the same crank?No No No!!!!(and still i...

Hi Francois, dis scan het nie baie mooi uitgekom nie. Kan jy dit asb weer scan? thx! Thinus,dit kom daarop neer dat jy n modifikasie goedkeuring van die ingeneurs afdeling van CAA moet kry soos omskryf word in die SA-CATS 44 dokument. Daar moet n fooi betaal word en alle goedgekeurde modifikasies m...

Thinus,ek weet nie hoe om die e mail direk aan te hak nie.Ek print hom,scan hom en save as n JPEG.Dan moet ek hom compress om klein genoeg te wees.Ek moet n ander plan uitdink.
