今年以來心力都放在三軸飛行器上，當然就對直升機疏遠了，雖然偶爾也飛一下，沒想到才稍沒關愛就問題叢生，抖動、擺尾、不好控制等問題都來了。既然三軸升天了，還是好好把直升機調整好才對。
雖然有人建議我拿台 EP200 去換 EP255，但我對舊愛感情已深，也知道他的毛病在哪，只要多加呵護，一定可以恢復青春活力的，不必一昧追求新歡。
上回 EP200FES 曾遇到擺尾讓 2612V 鎖不住的問題，經過一番拆解分析，問題全在"震動"上，現在的陀螺儀感度都很高，因此對於振動的防制是絕對必要的，不然陀螺儀就無法發揮應有的功能。
而老機子的振動來源就多了，除了主軸橫軸外，竟然連主軸軸承固定座都磨損了，新軸承放上去還可在裡面左右移動，難怪主軸和旋翼頭換新後，剎車盤還是無法定在中央，轉起來振動還是很大。
換過固定座和軸承後，原本以為摔歪的旋翼頭其實還是可用的，正好利用他改裝無平衡翼，以便使用那顆裝不成三軸的2702V。
後來發現直接拿舊的相位器來裝也可以，因為中心座其實是同一零件，上面還留有螺絲孔，用內六角鎖進去就不用再買專用相位器了。
現在主槳夾由十字盤直接驅動，為了減少伺服機負擔並增加解析度，我把十字盤螺距拉桿的球頭換成短球頭。
後來實測發現伺服行程還是太大，因此又把伺服擺臂球頭往內縮一孔，無形中又增加了力矩和解析度。
安裝 2702V 時，為了減少振動對陀螺儀的影響，於是把它裝在加強的底板上，遠離振動最大的第二層板，也為將來測試更靈敏的陀螺做準備。
裝好試飛沒問題，但是看到這張照片後才驚覺陀螺儀沒有緩衝空間，萬一摔機就危險了。
最後還是乖乖裝回肚子裡，加厚泡棉來隔振，看來安全多了，只是調整比較麻煩一些。
設定 2702V 很簡單，搖桿控制十字盤方向弄對後，跑一遍十字盤設定程序，就會抓到 AILE 和 PIT 伺服機方向，若自動調整方向相反則切開關就能解決。
由於我的機械結構和別人不同，更和華科爾V450不同，因此要自己找設定值，不能硬抄原廠說明書。
最後決定把伺服行程調最大，先把十字盤混控的 AILE 和 ELEV 設 100% 再跑一遍設定程序，這樣可以把伺服機可動範圍調到最大，設好極限後才調降混控率。
會這麼做的原因是觀察來的，若依照說明書把混控設 80% 去調極限，得到的結果有點詭異，當螺距打到極限時再動副翼的話，只見 AILE 和 PIT 兩顆伺服機只有一顆會動，因為不動的那顆已經達到設定極限，不能再轉下去了。
若真的這麼飛的話，除了螺距會跟著變小外，連俯仰角度都會被拉走，飛到緊要關頭時應該會欲哭無淚！
調校完成後，EP200 又開始新生活了，少了平衡翼，主旋翼的振動極小，陀螺儀可以發揮應有的功能。
第一次試飛時採取保守設定，接收機上的 DELAY 都設 50%，感度也是 50%，發射機上螺距和十字盤也都是 50%，飛起來極其平穩但動作緩和。
後來慢慢調整嘗試，DELAY 全部最小，感度全部最大，十字盤 65% 混控，螺距 55%，這樣保有靈活性並兼顧穩定性。
感覺 RX-2702V 的平衡效果比 2612V 好，鎖尾強了許多，飛行高度的控制較精準，所以我可以穩穩的起飛降落，個人感覺比以前好飛 20% 吧。
(只是兩個接收機的價差卻遠多於20%，不過若以整台機子的總成本來看的話，差不多就增加20%)
測試時把十字盤感度調到 100% 飛起來手感不錯，有種機子變大台的錯覺，而且在正負螺距交替時的機身晃動可以減到最小。
唯一還不滿意的是鎖尾，感度大於 65% 則自旋剎車會彈，等於 65% 又沒辦法把尾巴定住像根棍子，瞬間大螺距會輕搖一下，下次再改變拉桿位置試看看。
整體來說 RX-2702V 算是有進步的，因為以前的我好像很少能像這段影片這麼穩的起飛，現在翻滾後更容易控制高度，也比較不飄。
雖然最近左岸不斷有人說 2702V 飛行中途會讓馬達斷電等問題，然而我在 RCG 上面看到的卻是好評不斷，只要不要買到第一版就沒問題，所以我還是繼續用吧。
同樣的經驗也在 V120D02 上印證了！因為比較喜歡 4G6S 所以對 V120 沒有特別照顧，這次特別拿他來回味一下，不料飛沒多久十字盤就傾斜，另外機子也滑溜到很難控制。
十字盤傾斜是因為電池沒電，而飛沒多久就沒電是因為 JST 插座氧化，把電池和機子上的接點都用復活劑保養過就好多了。
但是機子滑溜則有點出乎意料，那種感覺應該就是許多人說的難以操控吧，因為明顯感覺三軸陀螺的介入，快速飛行要停止時沒辦法定點停住，反而像隻小船搖啊搖的，即使靠靈巧的雙手也只能減少而不能消除。
為此又重新嘗試所有調整項目，才發現 Delay 的功用，只是他的動作比較特別。
當Delay最大時，搖桿打副翼則十字盤能立即移動的範圍很小，接著才慢慢偏移到極限值。
當Delay最小時，搖桿打副翼則十字盤能立即移動的範圍大多了，然後再快速移到極限值。
所以Delay最小的時後自動修正很靈敏，造成機子過度搖晃，但Delay太大的話又反應不夠快！
最後調出一個折衷值 50%，配合最大十字盤感度，飛起來比以前好許多，既有穩定度又不至於搖晃。飛起來終於不會喝醉似的搖晃了，而航道飛行似乎又比以前好一點，只是抬頭狀況還是免不了，但是輕微些。
呵呵，這周末幫張無忌試飛他剛到手的 Trex 450 Pro，雖是二手機但沒飛過幾次，看起來質感比我的粗糙小機好很多。
原來 PRO 版和 SPORT 的差異還蠻多的，雖然緊實但比較難修理。
原機主裝了一顆台製新陀螺，選單功能強大，但是不大會用。
電變用上高檔的卡斯特 50A，不管怎麼飛都夠用。
可惜這天有點飄雨，加上新機螺距沒調好，只知道很好操控，鎖尾有點怪怪的，因雨就沒再試了。

Thanks so much!!!
I finally get my little heli up in the sky......
after I burnt my ssd-101us. I suppose it is
dead. It works in very first beginning. After 10
sec, it build up heat and running slower and
slower. 30 sec latter, it stop moving and draw
out all the power and make the receiver stop
working. It keep like this and finally I get my
7601 to the heli and the problem gone. But why
it burns my servo??? The issue happened when I
was setting the servo travel point. I remember I
came across this when I setup the heli. It keep
build up heat but actually it is on the ground.
But in one time it stay cool. Do you have
similar experience to share????
I am so exciting. The heli is so stable as I use
both flybar and 2702 at the same time. I still
got some tail wags in 62% gyro sense. Anything
to go for it? Tail delay??? BTW, is there
anything like belt tension which affect it?? - Ah Ng 於 September 27, 2011 10:54 PM 回應 | 來源:123.203.136.169 |

Thanks a lot!
I think I have no mechanical binding. I take the
servo and let it stays without any action, it
still build up heat. But anyway, I just let it
go..
For the 7601, I will try the shortest horn hole
and I will test it tonight. Hope that I could
have good result.

Are you using 6V BEC setting for 2702?? BTW,
poor me has the set button broken in my 2702. I

broken button.
On the other hand, I still have tail wag on it.
What setting you use in the tail delay and gyro

cause tail wag. Would you share your experience
in setting the tail???
Thanks a lot!

- 19樓Hi ej大,
Thanks for your advise. I've finally found out
the problem. Which I use sub-trim in my tail
rudder. It causes excessive vibration as it
keeps the rudder servo in command. On the other
hand, do you use sub-trim to level the servo
horn for those CCPM servos? I doubt it cannot do
it as well. Even though I have flybar install
together with rx2702v, I have to set the
sensitivity on the cyclic to lower to make it
works. Otherwise it will suddenly shake like
crazy. I suspect it is because I use a lot of
sub-trim to level the servo horn.

Thanks for explanation!!! I have ordered the new

ordered one??? It is much more cheaper than
Align and Microheli. Around 170 HKd! BTW, will
共震 happen with fbl head as well?? I hope the 共
震 is not caused by subtrim like tail rudder.
Because I use a lot of subtrim to level the
servo horn on CCPM servos.

- 21樓Hi ej大,
I have just tested with using a longer servo
horn on my rudder servo. The result is negative.
The shortest hole result in good tail hold in
normal flight. But it hunts tail when pump up in
pitch and thro to climb up suddenly. With longer
servo horn, result in decrease of force and
resolution, it get worse in tail hold under same
gyro sense. As a result, I suspect WK7601's
torque is not large enough to hold the tail. Do
you have similar result?? I plan to change a
rudder servo with more torque. Do you have any
suggestion??
Thanks in advance!

- 23樓Hi ej大,
Finally I drill a hole which make it 4.5mm in
length for the rudder servo horn. Now the rudder
delay set to min and gyro sense on 67%. The tail
is ok for normal flight but still has around 20
degree draft when giving a pitch pump.

- 24樓Hi ej大,
I think the subtrim that I previous set for the
rudder servo wk7601 had done an unforgivable
mistake that the rudder servo dead yesterday.
Finally I went to get a henge md922 and it work
very good. I am now have my gyro sense set to
72%. It holds the tail great! However it still
have little (around 10%) anticlockwise tail
draft in hard throttle increase. On the other
hand, I found that the tail delay must match
with different servos which vary from speed. The
henge md922 is not very fast. It moves 60 degree
in 0.07sec under 6V. If I decrease delay time,
the same gyro sense cannot hold the tail. If I
increase the delay time, the tail can be hold
still even increase the gyro sense, it heat up
the tail servo.

- 25樓Hi ej大,
For 0.07sec 60 degree speed, the rudder delay I
use is around 3:30 (in a clock). This makes my
rudder servo run cold. For the instance throttle
up caused draft, not sure how to fix it. But I
notice some drop of motor speed indeed. Would
you mind share your setup such as thro curve and
pitch curve??? Thanks!

- 26樓Hi ej大,
Thanks for your information. I have finally
install the FBL head from tarot and have a test
flight. I still use sub-trim for the ccpm servo.
When I decrease the balance delay and increase
the sensitivity, my little heli suddenly swing
and shake and cannot control. I finally switched
to throttle hold and let it fell from around 15
feet high. I broke the featuring shaft only and
it is the best I could have. Now I have question
that is the subtrim affecting it?? Or even I use
no subtrim and level the CCPM swash by adjust
the linkage, it still get crazy when balance
delay and sense too high. I doubt the 3-axis
gyro act like take gyro. - Ah Ng 於 October 15, 2011 02:28 PM 回應 | 來源:123.203.136.169 |

Thanks for your advise. I think why I lost the
control is because the SwaatMix value is too high.
I use 80% to setup. I down to 60% afterward but it
seems to be too high. I am using Tarot's new
250FBL head and it give to much when stay in 60%.
Now I am waiting for the part to repair the head.
I will double check on the pitch next time I
install the head. Thanks! - Ah Ng 於 October 18, 2011 04:53 PM 回應 | 來源:218.103.111.83 |

I found that I might come across too much
correction on my 2702 in my last crash. I
remember there was a wind blow and my 250
started to swing and no longer able to made it
stable again. Actually I came across similar
situation on my m120d01. I finally turn down its
sensitivity and Aile/Elev.EXT to ease the
situation. I saw that you have quite a lot
experience on walkera 3 axis gyro. Should I use
100% swash mix value to set the 2702 and turn it
down when actually fly it. Will it result the
same over correction??

- 30樓Dear ej大,
Thanks a lot! That's why I wonder! What I came
across was the heli suddenly look like it lost
the balance function and made me very difficult
to stable it stable. I can hover the machine on
3 sides and fly the 8 figure (outward). It
happen when I hover the machine. Suddenly a wind
blew, it loses it position rapidly. I start
correct it with stick movement. However,
whatever small among of opposite stick input I
gve, it responses like I have given a full stick
movement and swing back to the opposite
direction even faster. And finally, it out of my
control and I have to let it flaw in throttle
hold. But of course, I did not try just let it
swing and watch whether it will slow down or not
(flying field is not large enough).

Thanks a lot!
I think I have been a fool and made a great
mistake. I suppose the gain on the movement is
pretty the same btw flybar and bell head. But I
was wrong. Today I got my heli fixed. I serious
measure the pitch it gives and found that a 50%
of pitch swashmix already produce +- 10 degree
pitch. While I did fly 70% swashmix value on the
day I crashed my heli. I suppose the it
mechanically exceed the limit and finally cause
out the problem. I measured and adjust all
swashmix value and it is now a:40; e:40 (+-7
degree); p:50 gives me stable hovering and fly
if 8 circle. Hope it is the root cause but at
lease I safely have 2 batteries of flight!!!

- 34樓前輩您好,
看了您的回覆..有照著您建議的方法修正了一下調整~
小弟我的450是軸傳版的..這次把全部的齒輪,尾橫軸,傳動軸
都全換新啦~~
把震動減到最小..在不裝主槳的情況下,手拿著試機..已經沒
麼振動啦~
今天又去試飛了一下,開了IDEO 模式,尾巴已經鎖得住了~
(2801遙控器 GYRO 是設定 NORM & IDEO 都是 78%)
也可以小做鐘擺 & 翻滾 的動作了~~~
但現在就只剩下一個問題,停旋的時候 或 做完動作要恢復停
旋的時候~
會發生..機身左右搖晃(這時是50%),我試著把感度慢慢調低~
45%-->40%-->35%-->30%-->25% 這區間都會抖動(停旋
時)
再調到20%的時候...停旋時就會倒了(無3軸的感覺)
請問前輩您..是否有建議的調整的方式?
看到您上述的調整經驗..還開過最大耶^^我的開最大..抖到
不行^^
(後來慢慢調整嘗試，DELAY全部最小，感度全部最大，十字
盤65%混控，螺距55%，這樣保有靈活性並兼顧穩定性。)
對了~~可否再請較前輩您一下~~有關於 另一個調整扭
DELAY.
小弟我的尾伺服機是 亞拓DS520 所以把 DELAY 關到最小,
而十字盤的3顆是 DS929 ...那 DELAY 也是要關到最小嗎?
有點搞不懂 DELAY 的功能到底是什麼耶~~
(如果都關到最小,就不用設計這個調整扭啦)
小弟我..為了調這顆2702V ..已經重摔了3~4次..一直不願
意放棄這一顆~~希望前輩您指導一下唷^^
謝謝!!

- 35樓回覆32樓的飛友~~
小弟我也有這個經驗,除了混控值要調到最大100%(PIT也要)
~
還要注意.D/R是否也要開到最大,(我是連伺服機也調到
120%)
之後再去設定2702V的流程(中立點,前傾角,右傾角=循環螺
距)
之後再去降你的混控值(我的要降到65% = +-12度)
再調調整您需要的 D/R 大小動 & EXP 靈敏曲線..等等
這樣再去看您的十字盤,在最低點&最高點..是否有CCPM 動作
囉~~
這是我看到前輩先前的經驗,再去開最大設定後.解決的方式
唷^^

- 36樓前輩您好~~
參考了您的建議..今天把十字盤的delay與感度
(ELEV&AILE)慢慢的做搭備性的調整,現在NORM已經完全不會
抖動了..至於開到IDEO 模式,ST1的時候也不太會抖動了(機
身左右搖晃)..就只有 ST2 的時候..在停旋點(半空中吊著)
會發生抖動..但上下飛行(直上直下..正負 PIT)或做鐘擺..
側擺..翻滾..的時候..都不會有抖動的情況發生 ,但一停
旋..機身總是會給我抖個幾下~~
剛這樣調整..就上上下下來個幾十回,雖然不盡完美..但至少
已經可以小爽了一下~~
對於delay與感度的概念..慢慢的已經有所體會,就像您提到
的..不是每一台機子..都是固定的度數..因為硬體用的廠牌
不一樣~~
就像我的尾伺機..用亞拓500的 DS520 大顆的~~ 尾巴的
delay 就不能調到最小,現在大約在15%~18%之間,太小尾巴
會抖動到不行(因為訊號太快了)..轉過20% 又反應過慢,打尾
舵又不夠準,會拖泥帶水的感覺,後來調到15%左右剛剛好,鎖
的準..尾巴轉的又夠快~~~
後面要再解決 ST2 停旋時候的抖動..相信再調整個幾次..應
該會有所改善~~
非常謝謝前輩您的指導,好讓我繼續延續這一顆2702的信心~~
我是從4#6,CB180Z,V400D01..等等一路走過來的~~
現在有2台2801pro遙控器,因為飛機也好幾台在玩,甚至多買
幾顆RX-2437S(CB180Z 直升機的三軸接收)來應用在飛機
上,會自動平衡飛行動態唷^^ 風在大也不怕..因為住風城嘛
^^
後續若遇到其他的問題..到時候再請教前輩您囉~~
祝...飛行愉快!!

- 37樓前輩您好~~
回報好消息..我終於把小爆450抖動的問題找到了~~~~
就是一顆伺服機(副翼) 間隙過大的問題~~
原來伺服器使用時間一長..間隙變過大^^手拿機子加一點油
門..擺臂都會上下跳動~~ 實際飛行..在停旋的時候..就很容
易造成主旋翼上下震動..所以停旋的時候陀螺儀就會一直修
正~~~(難怪..航道飛行& 3D做動作的時候不會抖動)
剛剛沒事做 把先前掃齒的929拆掉~對調內部的金屬齒輪^^交
換間隙較大的伺服機齒輪~~現在間隙跟其他兩顆的間隙一樣
(多少會有一點..正常 新的也是有點間隙) 結果好啦~~ 抖
都不會抖一下~~~
現在換過之後...手拿著加油門..還有實際停旋..超穩的說
~~ 證明這一顆 2702V 華科爾3G 還蠻OK 的說~~~
跟前輩您分享一下囉^^ 也謝謝您的指導!!
