alright the kid won't post so I will, he just got his new dx7 yesterday and programed it last night. Today he flew a 1100 pack and the headspeed was crazy and the motor and pack got hotter then ever.Can you guys give some pointers on throttle and other curves for the HBK. Maybe some of your setups can help any help will be appreciated. He is currently running a basic -2, 5, 10 pitch and 0, 50, 100 for throttle setup. Thanks

I'm running a straight diagonal pitch curve in all modes on the DX 7. Throttle is setup 0, 50, 100 in normal mode, 100, 95, 80, 95, 100 in idle up 1 and 100 straight across in idle up 2. The blades are setup for -10, 0 at center, and + 10 at the top.

I fly it in idle up 1 about 98% of the time, get an easy 7 1/2 minutes flight time on a 3800 KV motor, 10 tooth pinion and MegaPower 1350 lipos.

It's been my experience that a hot motor and battery usually mean a head speed that's too LOW, or a pitch curve that's too HIGH. Either one will make the motor have to work too hard. and draw too much power from the battery.

Hell... I can fix that.
Uh oh..
Nope.
It's ***ked!!!

For normal mode I'm running 0 33.5 90.5 95 100. I like more consistant headspeed when pulling back on the stick. I'm working transitioning over to idle-up, but in normal mode I don't want to give up much headspeed.

As I recall you are running the Esky 3800 with an 11t pinion. I just went to an 11t from a 9t and there is quite bit more current draw, even for hovering. My batteries are getting much warmer and the motor and ESC is finally getting a tiny bit warm. I'd say if you are concerned about the batteries getting warm, either get better batteries or drop down 1 tooth on the pinion.

Congrats on the radio. I love mine.

Thanks for the info,I'm sure the boy will look at the board when he gets in. Gregor the only thing is that he's been flying that motor and pinion for a while with the stock radio and the motor never got hot and the batterys only were warm,it seams only with the radio change things are getting hot.Thanks again for the setup hints

It seems logical that if nothing has changed except the radio, that the radio is the culprit. Maybe the stock radio was never giving it full throttle or maybe the ESC was setup with the wrong throttle end points and the new radio fixed one of those problems. Just adjust the th and pi curves to be how you want and fly it.

Hmm... that's kind of odd. I'm with TJinGuy, if the radio was the only thing that was changed, it may be that the old throttle curve was not giving the motor enough welly. Last weekend I found it that it also ran well dropping the throttle curve to 80%. That might give you the current draw and headspeed you are used to. Its harder on the ESC so that might run hotter. Personally I LOVE the 11t at 95% throttle. Too bad it brings out a nasty vibrations my bird.... but I need to fix that anyway.

Norseman set your pitch up so that mid stick is 0* in each mode
normal pitch mode -2 -1 0 +5 +10
both Idle ups -10 -5 0 +5 +10
normal throttle 0 25 50 75 100 I like 0 50 80 95 100 but I like the higher headspeed when landing..
idle up throttle 100 95 80 95 100
The key to setting up your throttle curve is to have the same throttle value at mid stick because this is where your going to flip the switch in and out of idle up..when you use it... so if 50 is your mid stick setting use 50 in idle up
By doing this the rpm won't jump up or down when switching in and out of idle up and give you that torque rolling effect..... If you have any questions on this setup just ask away or you can PM me....

Thanks a lot for the info. I am running the 3 point setup now, so now im gonna play with a 5 point to smooth out everything. The only other thing i was wondering is with setting up the gyro sens. and the revo mixing on the radio. I have never played with this and any general pointers or basic setup would be great. Thanks

The rate gyro should work without the revo mixing. I have never used it so I leave it Inhibited, if you have a rate gyro there will be no sense lead I wouldn't think....
