I'm courious what to do for best results. I have a little 45amp esc on the mini titan se heli. Is it better to run a "V" curve on the throttle curve menu in my transmitter with a esc set up for gov mode or just a straight 100 across? Why is either of those set up options better than the other? If I'm running in normal mode and not with gov mode which option is better? Just curious.

Thanks, Keith

your best bet is to have the esc set to normal mode and fly with a 100% flat throttle curve as it will phase lock the motor.

Why is it better to run it 100 across vs. a v curve? and I can't say I know what a phase locked motor is. Your reply is very appreciated as I am pretty new to the hobby.

Thank, Keith

Wot to an esc is the most efficient and coolest running mode.

Because that way the head speed stays the same for the most part.
And yes i think the ESC is more efficient too.
NOTE: seems like i heard that 90% was enough. Someone correct me if i'm wrong...

edit: i'm not a big electric guy..

Indoor plumbing??? No, we don't need that!!!

100% is fine if you have good batteries. The throttle position just sets the voltage to the motor. People think you need to run 90% so that when the motor is loaded, "it has a little room to give more". This is true in nitros, but not so much in electrics. The reason I say "if you have good batteries" is because under load, the battery voltage will drop. However, if you run a slightly lower voltage than what the battery is putting out (ie less than 100% throttle), it's more likely to hold that voltage (and thus headspeed). This becomes less and less of an issue with quality high C packs. Further, the higher the throttle setting, the more efficient the ESC as was stated in a previous post. Unless I just completely botch a maneuver, when I'm running my 30C packs, my HS doesn't skip a beat in ANY maneuver. I can tic toc all day and the HS won't change (at least that can be detected audibly). Oh and I run 100% throttle curve, CC35 and JGF 500TH motor.

...now where was I, dh/dt = BS-dx/dt
I will fly you forever... till earth do us part

Wassup drumbum?
You should see the realy sweet canopy I got from guy that lives out by you. The locals here are impressed and I've even passed a few numbers out.

On to the subject and I'm probably the least likely to know but I'll spit it out anyway. On the governor function I've always been told it is mandatory to run a flat curve less than 100% (usually around 85) to allow the governer function enough room to increase the throttle as the pack runs down or under high load and therefore be able to maintain the desired HS. So in that situation you really need to be accurate in your pinion choice to get the desired HS as you'll be limited in what throttle % you can run and dont really have the option to adjust HS using the throttle curve.

As far as which option is better, IMO using a governor is better but only if you ESC has a good governor feature, otherwise just run a flat T/C as a bad governor will more than likely create problems.
