stall turn飛行時, 該用gyro的normal 模式還是AVCS模式 - 亞拓遙控世界討論區

是喔~所以直昇機沒辦法像飛機那樣飛到最高點自動轉彎ㄌ?!
快慢問題不會影響自動轉彎的程度嗎?!

陀螺儀應該會把您尾巴鎖住的,所以,當沒有速度時,也只會"退回來"~~ :-)
如果沒有退回來,那表示您的尾巴平常停旋時應該是鎖不住的~!!!

正確

我練習直線前進後退盪鞦韆的時候
都是這樣玩的
陀螺鎖得好應該是不太需要動尾舵的
直去直回如果會轉彎表示陀螺鎖不住了
既然要他鎖得好又要他可以自己轉彎
不太可能吧

除非他可以猜透您的心事

不是可以調整敏感度 ?
如果夠自然stall turn的最高點自轉,再配合設定的gyro sensitity就更完美ㄌ

如您所說,假設在最高點時馬上切換感度為前提.
即使是如此,小弟推測可能有兩種結果:
(1)感度調得"要低不低"的-->尾巴會晃啊晃的,也不知會往哪邊晃.
(2)感度調得太低的話-->尾巴直接往左偏(當作沒有gyro)

p.s.第(2)點,會依您使用AVCS與否來變化.
　 -->若您沒有設AVCS,而使用混控的話,那就不會偏了.但也不會"自然"的轉彎就是了.

若有推測錯誤的地方,還請大大指正喔~!

直升機在上空飛行的任何動作~都是手控制出來的~不可能設某開關動作切換自動執行~也來不及啦!
直升機最怕的就是~它會自動或不預期的自己作動作!

是喔
有些不是可以交給大自然力量去處理嗎　
因為我看一篇文章是咬提到
用REVO的設定不採用gyro索定
也就是把基本的扭地抵銷(靜平衡)
關於風力造成的動平衡上的問題
就要靠自己處理
到達最高點它會自然的受到重力影響
慢慢頭往下掉

貼一張敘述 for reference

FORWARD FLIGHT

When starting forward flight, keep the speed slow and fly at a comfortable altitude. You want to see the heli since you are developing its "visual cues."
Push forward cyclic gently to start forward flight. Be ready to reduce collective slightly to prevent the heli from gaining too much altitude.
If the heli is trimmed for hovering, it might pitch up, climb a little, and possibly stop. Give a gentle forward cyclic to keep it moving forward. You may want to add forward trim for steady flight and practice hovering with slight back cyclic. This should make forward flight easier.
Use left/right cyclic to bank the heli to start a turn. Avoid steep banking for now, and practice using both cyclic and tail rotor to execute a turn. Work on keeping steady altitude during turns.
Helis with low gyro gain or no gyro tend to turn naturally in the direction of main rotor rotation without any tail rotor control (i.e. right turns for clockwise rotating rotor). Turns the other way (left turns) will require tail rotor assist. For helis with gyro at high gain or with heading lock gyros, you'll need tail rotor assist in either direction.
High-speed turns with steep banking usually do not need tail control assist. Instead, use back cyclic ("up elevator").
Practice the correlation between fore/aft cyclic and collective in controlling forward speed. The more you pitch the nose down with forward cyclic, more collective you'll need to keep it flying level, and vice versa.
Practice landing approaches. You'll be looking at your heli nose-in most of the time. Keep the heli level (or nose-up slightly) during descent, and avoid diving the heli. This is a good time to adjust the Idle Up throttle curve to keep the rotor speed constant for collective below midstick.
Practice different forward speeds, angles of banking, and steepness of descent. When you are acting on the heli instead of reacting to it, you've mastered all the basic flying skills.
The next maneuver to learn should be autorotation. Not only is it fun, it may save your heli (I've saved three of my helis by autos). You may need to spend $$ for heavier/more efficient blades or buy a .60 size heli - you'll want plenty of reserve rotor inertia when practicing autos. This should be your first upgrade, and now you are no longer a beginner...
