Auto-Rotation Practice

[jamiem]

Im sure Stef will be along shortly to add to this, but just to start the ball rolling on a strange problem with his, we started flicking the throttle hold switch at waist height to get used to landing under dead engine conditions, and to get towards having the balls to try auto-rotations. mine was fine, generating plenty of lift (enought to take off again to a height of about 2 foot - mistakenly!), and i eventually got it right. however stefs just wasnt generating the lift. at full pitch it was only enough to give a gentle landing, certainly not to hover it for a couple of seconds like i did. his is a raptor 30v1, with 10degrees pitch at the top, 5 in the middle, 0 at the bottom. running standard wooden blades, with a 1700rpm head speed (as checked). mine is running identical, but is a v2, however mine generates loads more lift. any suggestions on why they behave totally different?

If as I read in your other thread you are flying cicuits and such like you really should introduce some -ve pitch to your curves. Not sure what the pros reckon but as soon as I was OK at hovering tail in and had stopped chopping the throttle I set my curves to:

Normal -6 0+9(Only used for starting up)
Idle Up-9 0 +9
Hold -9 0 +9

yeah this is on the cards for the next flight, however this still doesnt explain why our 2 identical setup's behave totally differently - i can produce plenty of lift as and when i need it, stef on the other hand can barely slow his decent. possibly he has a different pitch curve on his throttle hold switch. Stef if your reading this, check it on your new transmitter! didnt think about it while we were at the field!
