Yea, well I had my Furion 6 inverted and hit throttle hold. That was exciting. Now my telemetry is programmed to yell at me if the head speed drops below a set value.

I'm sure we've all hit a switch accidentally during a flight. I was playing around with the E640 doing pitch pumps to check the tail holding power and hit my flight mode switch while switching from full negative to positive pitch. This dropped the head speed from 2300 to 2050 and made me think I put the ESC into overcurrent shutdown.

That is a very valid point. I don't actually "use" normal mode. Last season I would leave the flight mode switch in idle-up and I would flip out of throttle hold to spool up. This season, I started taking off in normal mode and then switch into idle up once in a hover. But I usually hit throttle hold a foot off the ground to land.

My bigger problem may be that I'm the only heli pilot in my very small club and I have a little voice in my head that says to invert the heli as soon as possible to get a crowd reaction. I may need to work on that personality defect.

Sound advice. I wish I could promise to heed it.

Yup. If you ever hear somebody say "Hey guys watch this" you darn well better watch. Odds are its going to be expensive and spectacular.

I didn't say one more flight or watch this for this one, though I almost got taken out by a football:

I still use "normal" mode for a few reasons:

1. old school, I started on a nitro FP heli with an airplane radio - no such thing as throttle hold

2. safety, throttle stick held at 0 by thumb, "normal" mode and TH switch on gives me multiple off switches thus if one is bumped (in theory) the heli should stay put

3. when doing a maiden (insert your own joke here) "normal" mode is usually a tame headspeed and if anything goes wrong on spool up or first hover I can put the thing on the ground ASAP. Yes, hitting TH would accomplish the same thing - see #1 old school (I tend to move the throttle/collective stick before hitting TH)

I'm all for doing whatever you're comfortable with so it is all good.

I appreciate Hance flying lower when I gently suggest that he fly lower...

All good points. I do the belt & suspenders thing myself when I walk to the flight line - heli in right hand with ring finger on anti-rotation bracket (so it won't spin as I'm walking), and transmitter in left hand. Thumb holds throttle at 0, flight mode set to normal, and throttle hold on. I've also got my 500 set up (and will soon do the same to my others) so that the ESC doesn't initialize until I move the throttle trim to almost 0 - and I don't do that until I get to the flight line. The internal BEC is energized as soon as you connect the main battery, so the only thing that isn't armed is the motor.

I'm not saying you SHOULD program out normal mode, I'm just saying it can be a viable option. You'd just have to program in other compensating controls.

If you are flying electric, there is no need to use a throttle curve that is not "flat" - let the governor handle the head speed. If you want multiple head speeds, use the flight mode switch to set the curve at the percentages recommended by the governor. Use throttle hold to set the ESC to "off." Your Tx turns the motor on, and it turns it off. Let the governor do the rest. And yes. an external governorconnected through your FBL unit works better than the one in your ESC.

Right, hopefully my post didn't read like you were advocating removing normal mode. That was not my goal at all.

I'm a big fan of using a method that is comfortable and familiar ... 'cause when things go wrong it'll be your muscle memory that shuts it down.

Edit: forgot to mention that yes, I am weird, I run governor in all 3 flight modes: normal, idleup1 and idleup2.

It's all good.

Perfect for those "unexpected" landings in the deep corn. As small as it is, you could move from frame to frame as you switch-up aircraft.
