Default Throttle/Pitch curves

What are good throttle/pitch curves to use for hovering? I am currently using 7,28,50,75,100 for throttle and 0,25,50,70,100 for pitch and im not getting into a hover until im almost full throttle, does that sound right??

Wow sounds like you are having a similar problem like me. You are not getting enough head speed of blades. I can tell you that much. I know only one thing. You may want to adjust your neadle valve and speed valve. That is what I am experimenting with now. My helicopter right now will start to hover at about 2 to 3 clicks past mid stick. I can bring it up hight in the air, well I have never really tryied that but I think I can. It just is not getting enough speed, even though I have my pitch and throttle curves set for hover. It's like sometimes my engine gets too hot or something and I don't have enough power to get off the ground. My pitch curves are set at 15, 43, 63, 77, 85. I don't know if this works for others, but this makes for more ease to me. This setting makes the pitch easier to me so that the heli does not shoot up in the air. It just eases up. But this is not the power loss I am talking about. Lets see what someone else might say how to fix your problem. If your servo is hooked up right and the engine is openning and closing propperly sounds like it could just be the valves. Try that.

Yea i dont think im getting enough head speed because when i see vids of other raptors there getting way more speed than me. I think thats also the reason why my heli shakes and wobbles when i set it down. How do i get more head speed?

well its not your throttle curve coz thats in good order by the looks.. errm id say first establish if teh engine is cool or hot, id bet a million bucks your too rich. but stick your fionger on the backplate after sppol up i doubt youyr to lean. thouigh u;ll be too rich . which mean u have to adjust your needles. ummm what engien and muffler?? and where r the needles now?

I was running a tuned pipe but switched to a Mac because the pipe wasnt secure and was vibrating, i have the stock muffler but the holes dont match up. Your right i am too rich because the last time i tried to fly it the engine bogged. The engine is an OS32. Ill check to see where my needle is now.
