Walkera HM-4G6 micro CP heli hovering

Walkera HM-4G6 CP micro heli. Main rotor dia: 11.9" (302mm), AUW 3.1oz (88g), 3.7V500mAh single cell Li-Poly battery. My bird was factory assembled but NOT RTF. Adjusting and tuning were required. This vid shows my fourth flight. As this bird was so twitchy to hover in my small living room, I replaced the stock flybar paddles with heavier ones (1.6g each) and reduced down the D/R for aileron and elevator to 50%, EXPO5%. I also set an aileron to elevator mixing +26/+13/0/-13/-26 and an elevator to aileron mixing -26/-13/0/+13/+26 for better cyclic controls. Although she is a bit docile and stable now, still very very challenging machine for me.

Hello,

Good video.

What are your settings for a machine as docile and stable?

What throttle curve and pitch curve?

I read that you had put 5% expo on aileron and elevator, right?

Thank you

Yes, 5%.

Kudos to the successful indoor CP flight.

Ducky - LOL! I see 'em now. I look like a chatterbox! Non-stop.

@bscfo1 lag time buddy...all 4 of ur comments posted.

Looks very twitchy, I would add a little bit more expo to reduce the sensitivity\throws of the servos.

I tried to comment 3 times. Not posted. What's up YouTube?

Nice little helicopter, I think I may need one of these! You're doing fine - I have a Micron, they are very twitchy and always a challenge. Have you tried shortening the total pitch range and raising the hover pitch? That will reduce the head speed for a more softer feel for hovering. If you do this you'll need to retrim the tail.

[bscfo1]

Very cool - these little guys can be very hard to control, even your air conditioner can affect it. You can try shortening your total pitch throw, and raising the hover pitch to decrease the head speed. That will make is softer in the hover. You'll have to retrim the tail after. Use your exponential settings if you have them to make the sticks less sensiitive too. Have fun.

That is such a cool little helicopter. They are very tricky, even the air conditioner can move enough air to push it around in a hover. Along with the dual rates, you can try the exponential settings to make it less sensitive at short throws of the sticks for hovering. Maybe less pitch range, higher hover pitch and less head speed would help make it less twitchy too. Try getting it way out of ground effect (waist high) so the rotor wash doesn't effect it. Carpet helps too. Have fun.
