thanks for the advice and it looks good i just got home and i read a bit of it but 1 question before i ask my next question if i have one after i read.

if i were unseeing governor mode my headspeed would only be for example 1800 in normal mode straight across in relation to what ever my pitch curve would be right ?

and i think i understand what your saying im gonna read it now and thank you sorry if I've been a pain.

airdodger In normal mode the curve should be something like 0-25-60-80-100 with atv around a 100. The pitch should be around 5 at mid stick hover if you think it will pull 11 use 11 top pitch. It is important that the throttle is advancing before the pitch. Adjust the high speed needle so the smoke trail is steady and smoking good, do a vertical pull and see if the head slows down it will be apparent. Check to see if the engine is getting too hot, if it slowed down always open the needle first, if opening the needle made it worse lean it, if neither works you are pulling too much pitch. If you are not sure use a new plug and pull it, should look no different than when you installed it. If the coil looks frosted or distorted or any color at all it is too lean. The throttle has to be full open to adjust the high speed needle. If the engine does not settle right down after you throttle back it is too lean and getting hot fix it, if at anytime you think it is too lean don't wait a second fix it. It is easier on the engine to rev than lug it, to a point. Listen to the other replys that stated the engine likes a high headspeed in the 2100 range. I don't know if the low mid needle affects the high if it does you need to have it open enough to supply the high. If you can get with somebody with experience they will be a big help.
wow awesome i got it you explained it just like bert smacktalk rc .

so if im at 100% throttle with my motor and pinion will not go over 2300 rpm ?

just so i know.

and if 35% throttle gets me 1700 rpm then mid stick should get me around or a little over 1800 rpm to 1900 rpm max ? and 100% want go past 2400 rpm ? i dunno what 100% max would do and ive been afraid to try it but if you tell me it wont go to 2900 rpm @ 100% then i want be afraid lol i trust your word. (smiles)

and i will get some field help and thank you for helping me to understand so i will know some what of what they are talking about when i get to the field

and yes im feeling kind of small

Please note I said run your engine at 18500.

NOT 1800 on the head! There is a big difference. 18,500 divided by the gear ratio of your heli will give you your head speed.

The Novarossi likes to rev more than O.S and YS

Check the spec

one last question.

if my throttle curves are linear how do i keep a 1850 rpm headspeed without using the throttle curves ?

atv's

Why do you have your throttle curves liner? What if your governor goes out?

Heli 770 Why do you have your throttle curves liner? What if your governor goes out?
suppose to set it up with out the gov first.

but still .

i guess if i use normal curves mid stick head speed will be 1850 and max 2250

i guess what im tring to ask is how do i adjust the head speed if its not done by throttle curves ?

my thr curves are 0-15-35-35-35 for normal mode
but i think ive been told to run it linear in this post.
read back.

Run the engine a few clicks richer than normal that will keep the headspeed down.

sure but i want 1850 rpm for normal mode and 2250 for idleup

how do i do this if i cant be done by the throttle curves ?
atv's
airdodger In normal mode the curve should be something like 0-25-60-80-100 with atv around a 100.
100% throttle is gonna give me over 1800 rpm

You can do it with curves but first you have to tune the engine. The curve I mentioned was just a ballpark figure to help tune the engine. after that just limit the end point of the curve, or turn the gov on. Yeah a 100% might give you the headspeed around 2100-2200, you can set idle up one and two to get different headspeeds, after the engine is tuned. Get with someone who can help you life will be a lot easier. Most people don't use curves except for backup.

not sure if i can setup the end point for the throttle per idleup condition.

but im sure i could use throttle end point if the hs exceeded 2250 rpm @ 100% throttle .

but to have a 1850 rpm hs max for normal mode i may have to use the throttle curve to do so ? or is their another way ?

then after its all tuned and setup ill plug the gv-1 back in.

also last question id like to ask is tuning done in idleup ?

and thank you im stating to understand.

The throttle needs to be set going through the full range it will be used in, does not matter what mode you are in. Once the end points are set, you use the curves, the end points set the throw limits, full open full closed, once set you leave them set.. The curves work to reduce the opening without effecting the end points. But the throttle has to be set correct also. That is why you need to tune using full open. If you reduce the end point you are tuning the engine for that throttle opening, if you reduce the opening you reduce the airflow hence you reduce the fuel able to be drawn out of the fuel bar. So if you set the opening at 3/4 and tune you have reduced the fuel flow by limiting the air mass. You may be able to turn the engine almost the same rpm but you have cut the oil fuel by some percentage. The carb was designed to flow the correct amount of fuel for the design parameters of the engine, full rpm, carb full open and max fuel= max torque. Most of the time once the rpm is set the increase in throttle does not give an rpm increase but a torque increase, torque is what the hp is derived from. Again you need to get with someone so they can check the setup it will be painless.
