This is what I said:
Just to add my 2 cents. I don't think the Jazz needs to be spun up (rotor blades spinning and all) to 100% throttle the first time. That is only for the AMP mode (mode 1) and needs to be done on every battery connection. We use Heli mode (mode 4).
So no you don't need to spul up the heli to 100% at all, never during the setup process or after that. You only need to do that if you were using mode 1 which is AMP mode but we fly helis in gov mod so we use mode 4, Heli mode instead.

I just spooled up the heli without the blades to full throttle. Man, the box (from TP Packs) makes a big noise (metal gear against metal gear) but is very cool! I'll post some pictures later in a new thread.

Dnam, I am sure you know this but if you have the gear mesh to tite in the box it will sound alot louder, make sure you have just the right mesh in there Let us know what you think

I am setting up my Jazz controller now, and I understood the throttle normal curve setup explained by Dnam. But what ablout idle up1 and idle up2, should the idle up1 be a straight line at 45% or so, and idle up2 at 80% or so?

Thanks
Duc

Hi,

I have mine set like this,

Normal 48, 48, 48, 48, 48
Idle 1 55, 55, 55, 55, 55
Idle 2 72, 72, 72, 72, 72

I use throttle hold for connecting and disconnecting the flight pack.

On the first spool up set idle up 2 too 100% straight across. Let it spin up at 0deg pitch at 100% for a few seconds until the headspeed settles, then switch off and reset your idle 2 too whatever throttle % you want, you can leave it at 100% if u want.

Simon.

Thanks Simon. Does that mean you have to setup throttle hold at 0% straight across, and use it as when you shut down, or when the throlttle stick goes below 48% throttle, the Jazz will automatically shut down the motor?

Thanks
Duc

One thing about the ESC is that the juice it pumps out doesn't always correspond to the radio throttle percentage. For example on my JR radio a setting of 90% throttle on the radio meant 100% on the ESC. However on my new Futaba radio 100% full blast from the ESC when I am at only 45% throttle on my radio! Easy way to see what corresponds to 100% ESC power is to disconnect the motor from the ESC so it won't start spinning. Just set a default throttle curve going from 0-50-100. Arm the ESC and start pushing the throttle stick up. The red light on the Jazz will come on and stay lit when it is pumping out 100%. Just note the position the stick is at now. Let say it is at 90% when the ESC is at 100%. To set 80% for the ESC you would have to set 90% x 0.8 = 72% on the throttle curve.

Just remembered something. Duc if you are new to e-helis I would suggest taking the blades off before you first spool up the heli, to see if the throttle stick reverse setting is right. When you want to initialize the Jazz you have to pull the throttle to full down position, the motor should give a little sound and the red LED lights up on the Jazz. If this doesn't happen your throttle channel might need to be reversed!

Thanks Dnam. I had indentical equipments as yours with one exception that I use the Futaba 9ZWC2. But all Futaba heli radios should be the same on servo direction. What direction do you end up with for your thottle channel?

Yes, it will be flown this weekend. David, I use the orbit pro charger, should I set the the max mAh limiter at 4000 mAh or just let the charge do it job. I going to charge the TP pack tonight with 2A charge rate.

Thanks Duc

Duc, you can set the max mah setting to 4000, if you would like I am willing to bet most guys are not using that and just letting there charger do its thing. I set mine to the max mah 4000

Either way you should be fine, you will only put in around 2000 mah any way, it comes with some what of a charge from the MFG

PM me or call me after you get a flight or two in I can't wait hear what you think
Take care and good luck

Thanks to Simon, Rcman, and especialy to Dnam for your support with the setup of my 3DMP. I loved the setup procedure from Dnam, straight forward and quick without the need to spin up the heli at 100% throttle. Dnam, my max throttle with the 9ZWC2 is 90%.

I got m 3MP in the air today, and all I can say is wow...it felt like cotton in the air. I never use expo. to slow down the cyclic on any of my gas machine, and I had to installed 30% to the 3DMP to keep it in still hover...it was windy this morning, too. I did about 8 min. of flight time at 1650 RPM...that thing rolls and loops so quick even at this speed, and climp out is unbelievable. Check the pack after and still got 38 volts.

Thanks every body. I need to save money for another pack.

Regard
Duc

I had three flights this weekend, and what a machine. I have not seen any thing climps that fast before. And the V-2 box was so quiet it's difficult to judge the HS. SUnday the wind was 25 MPH, and the 3DMP with the pointed nose pennetrated the wind like there was no resistant, and yes hover steady at this wind speed. Inverse backward knife-edge was so fast, it's scary.

I still don't like the 401/volz combination. I had to do too much adjustments at HHS. Have a good head holding, but I am so use to with the solid state of the 601. I have a spare 601 laying around, so I will put it in. I don't thing the weight is and issue here.
