Where do you want the throttle stick to be in the hover?
If you want it to be half way up then this needs to correspond to hover pitch and throttle. This will be about 5 degrees pitch and 50% throttle.
In this case start with the following:
MAIN BLADE PITCH
Pitch curve: -2 degrees pitch at bottom, 5 degrees at middle (Hover) and 9 degrees at top
Throttle curve: 0% at bottom, 50% at middle and 100% at top
Any other points filled in to give you straight(ish) lines on your curves.
HOWEVER, for a beginner I
might think about setting the bottom to 0 degrees pitch initially. This will soften the pitch response slightly.
ROTOR BLADE PITCH
I've got my rotor blade pitched mixed with throttle such that from
50% throttle to 100% throttle it goes from 0deg pitch to 12deg pitch.
I suspect that may be too agressive, as I'm taking off before I have
full rudder control.
If you are trying to hover at half stick then here is you problem. As I stated in another post you will need some pitch on the blade to prevent the torque reaction from spinning the model in the hover. If your Raptor blades spin clockwise when viewed from the top (they should) and the tail rotor blades spin the right way round then the trailind edge (back part) of the lower blade should point very slightly to the right to prevent constant spinning. The best way of setting this up is to ensure that at the tail rotor end, the pushrod is at 90 degrees to the part of the tail pitch control lever that it is connected to. This will give you a rough starting point.
If you want to hover at 3/4 stick (there are reasons for doing this) then the curves are different.
It is hard for me to explain this but I can tell that your heli is not set up correctly. Go to
www.raptortechnique.com and have a look. This will explain the setup process. I'm not sure if he uses a Raptor 60 but the process (and most of the figures) will be the same for a beginner.
Hope this helps
