Do you mean "to hover" at 1/2 stick ??

Either way you'll need to adjust the pitch to about 6 degrees at 1/2 stick and then adjust the throttle to suit ....

And last question, why do you want to do this ?

Been there, done that and old enough to know better.....

Thank you.......I guess i'm trying to find out the best way to "hover" my Mongoose at 1/2 or 3/4 stick.

You could set the head up mechanically for -2 to +12 degrees of pitch.
You could set the curves in your radio to limit the neg pitch.
You will have to fly in idle-up because the heli will not come down without bringing the collective down far enough that it cuts the throttle.

First you need to know your gear ratio so you can set the head speed for your engine then when you have that set adjust your pitch to get it however you like it on the stick easy as 123 All of my gassers hover at three-quarter stick,,, that's -12, zero, +12 pitch. It helps if you're running a governor if not you'll have to adjust throttle and pitch curves. XGM/VGM

well technically, yes, you do all three...

showing a preference will only get you into trouble, 90% of everything is crap...

One could assume from this question this is not intended as a 3d setup.

I would have thought most non-3d flyers are hovering at ½ stick as it gives far nicer stick resolution.

Just set -2, +6, +12 and adjust throttle curves to suit. The best tacho is your ears, if it sounds right then it probably is. Not really sure why you would need to think about gear ratios except for initial governor setup. Not everyone picks a headspeed based on power curves.

Good luck.

Mongoose

Run the head speed at 1320, 1400, and 1480.

Gear ratio is 9.09.

You can hover it at 2/3rds stick and it will fly inverted and hover symmetrical stick to the downside.

Probably won't be sble to swing 12 degrees my guess would be less due to the larger disk. Put as much pitch in it as it can take to climb out holding 1480.

Enjoy!

1/2 throttle isn't

Predator Gasser here and I found out also that half stick is not half throttle with a gasser. I run about 1/3 throttle at half stick 6 degrees in a hover. I run mine very scale with a lower head speed than most. My blades are even wider chord like FBL blades with a fly barred head.
