Engine help

[Tresguey]

i have my needles set as per what the book says. i have been flying airplanes for a long time and everyday berfore i fly one i readjust the needles by a full throttle and adjusting by sound. im sure this is not how i would do this on a heli. how is it done? and how often. also i have been looking around and seen that people use different servos for the tail rotor and throttle. im guessing for torque or speed purposes. what is recomended as i only use the ones that came with my radio.

Generally you should not have to adjust your help motor more than a couple of clicks either way. The Gyro your using usually determines what tail servo you can use. The throttle servo is much less critical. Even some of the top flyers use cheap servos on throttle. What radio did you buy and what servos did it come with?

[Tresguey]

i use a RD8000 and a JR g500t

[WillJames]

The 500T is a good Gyro. I'm a Futaba guy, but I think you need a 9253, or 9254 or JR 8700G servo for that. I have heard that the Airtronics radios are good, only had JR and now Futaba myself.

thanks baja, i guess that those servo's are a bit quicker than the stock type? and what about moveing it to the boom instead of where it is mounted by the manuel? it looks cool there but what is the reason people do it? is there a performance advantage of doing this? thanks again.

[WillJames]

I would recommend against moving it until you get some serious time and experience under your belt. It is much better protected up front in the event of boom strikes which will happen to you sooner or later during the learning stages.

The tail servos have a lot higher frame rate than standard coreless or digitals. Other than that, I don't really know exactly what is different.

well the main diffrence is they are twice the speed of a regular servo :cool: guessing you forgot that bit.

Personnally i much prefer the boom mount as:
a) no readjusting the TR linkage when you adjust belt tension (not that you will be doing too much of that where you are)
b) straight line carbon shaft -- no flex and alot freer then those guide things
c) helps balance on my particular machines (hugungous :mrgreen: DL pack at the front)

But on the down side there is a great likelyhood that when you crash you will rip the wires out of the servo along with the oil to contend with, that said i learned with a .22 second servo in the stock location and didn't need anything better until started FF and aerobatics.

Haven't tryed the 500T yet myself but have one waiting for spring and will be using a 8700g servo with it.

IF you do choose to go to a fast servo with it remeber some have special requirements (8700g is PCM only and a battery hog for one)

man do i have alot of learning to do. i thought that since i am a pretty good airplane pilot that it would be a snap to get into heli's. man was i wrong. i should of started out with heli's. but thanks all for all the help!!!!

Hey i started with planes too, still fly them as well -- dispite what people say alot of it carries over, FFF with a heli is alot like a low wing symetrical winged plane (just you hae to use rudder with heli's).
Just in genral heli's use better servo because on a plane you can fly without rudder or throttle if it dies -- not so with a heli and a heli isn't as equipment freidnly as a plane. Also heli engines are less picky about tuning the planes, most people tune their plane for absolute most power at top end -- on a heli the only time you will be flat out is in a full power climb (at most i adjusted my needles +-3 clicks all year flying at diffrent elevations and within a 30*C+ temperature range) plus most heli's fly with higher nitro then planes which makes the needling less sensitive to atmospheric changes ect.

Finaly, heli's don't knife edge very well :wink:

[WillJames]

Right on Spitty. I fly planks and helis both. Probably 50+% of people I fly with do.

H to the C always says that flying 3D foamies helps with reflexes, stick skills, coordination of ail-elev and rud and orientation. If his flying is any indication, he is 110% right. Clintstone and Jody Greer were also large scale plank (IMAC or whatever)

Aviation is cool so why limit yourself. :lolol

[Tresguey]

i am not into 3d plane flying which basicly lets you know that im not used to useing the right stick. what i was trying to say that if i got into heli's first that it would make me that much better of an airplane pilot. not trying to make excuses of my lack of heli pilot skills just wondering on what could of helped me out better in the long run. :mrgreen: and i will never give up on helis or planes!!!! there all fun.
