JR8103 setup help

       Remove this ad - become a site supporter!
I just bought a used 8103 and could use some advice on setting it up so it works well with my heli(I previously used a Futaba Skysport6ch so I am totally new to PCM) . I've got a Hawk III with a TT36 engine, a CSM 180 gyro and JR811 digitals. I've flown micro-electric heli's and became pretty proficient at hovering and some basic circuits so I'm not a totally green flyer. What I need is some advice on how to setup the various radio functions . Is there anyone out there flying a similar radio/heli setup that is about the same skill level, and wouldn't mind sharing their setup with me. Or an experienced flyer who would be willing to walk me through the setup process. I think this heli is pretty much ready to fly, I just want to make sure the radio is setup right, the first time.

Spring is just around the corner and I can't wait to get flying. I've got a feeling that this is going to be a great year!!

What exactly do you need to know? The 8103 is a very user friendly radio, it won't take you long to figure it out (if you know anything at all about radios). Did you get the manual with it?

Do you have a pitch gauge? This is going to be crutial... As far as setting up the helicopter with a 8103, it is very easy, just as charlie said... Both of us should know, I use one, and I baught it off charlie.

You will need to go into the pitch curves and set up the correct pitch for each flying mode.

If you want some help, post more detailed questions. Another thing you can do is go to raptortechnique.com. It is a raptor web site, but will provide lots of useful information about setting up a 30 sized helicopter.

If you have any more questions, please feel free to ask.
you don't need CNC if you are handy with a torch.

I've got the manual, pitch guage and all that stuff. What is the correct pitch for each flying mode? Also my tail servo is jittery and I'm wondering if this is a radio setup problem and how do I fix it. I'll check out the links you guys have suggested and see if that answers my questions. My biggest problem is that I have no one to check my settings and see if my heli is performing like it is supposed to. My micro electric was easy to fly with almost no setup, the nitro's are more intimidating to setup(more moving parts & adjustments) especially when you're new to the hobby. Thanks for the tips.

Don't let the setup intimidate you Warren. Do some reading and take your time. A simple rule of thumb for the Ergo's are keep your servo arms at 90 degrees at neutral or half stick. Stick to a simple pitch curve of -4 degrees to about 11 or 12 positive depending on blade profile. Adjust your throttle curve to maintain rpm thru all pitch settings. Once you are comfortable and out of the hover mode then look at an idle up setting to maintain rpm in a descent. A good blade rpm to start with on the Ergo is about 1700 to 1800 esp with composite blades. A little less with the woodies.

If you can, get some guidance from a seasoned vet.
