Default RE: I have a question

CHRISTANEAGLE: ... Before it came up at half throttle now it comes up at nearly 3/4 throttle. My friend set the pitch and test flew it between rain showers. He thought it was ok but it's just not the same.
On a very beginner setup, the tendency is to achieve hover pitch/power about mid-stick (in NORMAL mode). Once you graduate from just hovering and flying around, pilots tend to set their normal mode pitch/power (at least mid-stick to full forward) to reflect what their Idle Up modes are set to (ie 0 pitch at mid-stick and hover around 3/4 stick). Your friend might have set your Normal pitch/power curve up the way an advanced pilot would have theirs. Might want to ask your friend about this.
CHRISTANEAGLE: ... My question is on the frame is a scale (I guess this is for pitch) it is not even close to what the book says. He set the pitch with a pitch guage so is this the same as using the scale just a diffrent way of doing it?
The scale represents the positioning of your pitch servo NOT the actual pitch of the blades. As barracudahockey said, the frame gage is only accurate if you adjust your blades actual pitch to the same as what the frame gage is reading. So ... you have to measure your blades pitch with a pitch gage in order to see if the blades are set to what the frame gage reads.
CHRISTANEAGLE: ... Should it be set up per the book using the scale then use the pitch guage to fine tune it ? Should the pitch be set using the pitch guage and not worry about the scale.
Again ... the frame gage is used just as a reference point to where your pitch servo is. It CAN NOT be used to set the actual blade pitch ... this requires a pitch gage.
CHRISTANEAGLE: ... I have a 9 cap futaba radio.
These are nice radios except that the left stick (assuming mode 2) is ratcheted ('bumpy') on the aircraft version (9CA). In order to have any success in heli flight, this "bumpy - ness" needs to be removed so that the stick can move smoothly (like the 9CH version).

Good Luck,
