我在改隻 1米既 ArtHobby 机,打算將個 V尾 elevator 加多個 rudder 功能。但係用既 Futaba receiver 得 4個 ch. 唔夠用!手上其他既 6/7ch receiver 又太大,放唔落! :(
有幾位師兄都講過、話有方法加多2個ch.落去。
:o 請幫幫手,過D料泥!

K.Y.Mak 師兄你好
國產飛高 6ch 接收機,呎吋和 Futaba 114 差不多,售價145元人民幣,我裝了落ArtHobby DL到用了2天,未死機!!幾好.師兄們星期六中午是不是去坪輋歡迎我嗎?

Hi!亞麥, 有否考慮用mix解決你個問題,如果無用到ch3,可以試下以下方法(係試下) :D
張rudder插入ch3再做以下步驟:
1) mix1 ch3 to ch3 +/-100%(完成後ch3只會停係中位)
2) v tail (on)
3) mix2 elevator to ch3 相對正確動作 +/-50%
4) mix3 rudder to ch3 相對正確動作 +/-50%
我set過哩玩,但無正式用哩飛過因為無需要 :D :D

Hi Mak,

Most of the Futaba receiver use the same channel decode IC for 4 channels to 8 channels.

All you need is to locate the channels output pin from the IC, you can trace the from servo connector side.

You will find out that some pins of decode IC did not connected, they are the extra channels.

Then you need to solder a connector to get them use.

I can show you next time when we meet.

Chester, 個粒 PPM 解碼晶片既輸出腳同 servo 中間有無 driver 線路呀 ? 係唔係 open gate output 黎架﹖駛唔駛加 pull-up 電阻呀 ? 等我試掂之後貼D相上黎比D朋友睇﹐咁就人人都可以用 250 蚊就買到個 8 Ch 接收啦﹗

聽日由于風大同無太陽﹐坪輋不宜放機﹐我地星期日會入深涌比賽手掟機同彈射熱氣流機﹐有興趣可以一齊黎。

I just solder a wire from the IC pin to a connector for servo. Since I have done this with several receiver and no problem found.

I may check the circuit again to see if pull up resistor needed.

Thanks
Chester

多謝各位師兄所提供既資料。我可以用個 Futaba R114F 用到 ch7 啦! :D
好多謝email 泥既相片!雖然個 R114F 用既 IC 同照片上既R115F唔同。我最後將個 receiver 粒 IC D 腳一隻一隻咁試‧結果 ch5,ch6,ch7,ch8 全部都到。
:? 最大問題係 R114F 粒 IC 好細粒,要燒條 signal線落隻腳度都唔係咁容易!
:evil: 要用刀片將隻 IC 腳挑起泥、燒線既時候先冇咁易燒埋落其它IC腳上面!
燒左上去都好怕易髯。我打算用epoxy封住佢。希望唔會飛飛失靈啦!

其實我都唔明佐治所講既 mix 係點set? 用 Futaba 9仔做唔做到? 如果 set 得到就唔洗咁冒險啦! :?

YC, 我開過隻 R116F, 粒IC 既 signal 腳睇泥係直接出訊。中間冇任何子零件既。 :wink:

Hi 佐治,
如果 set ch2 同 ch4 控條V尾, ch1 控右翼,咁 ch3 (throttle) 就要控左翼。
我試過你個 setting, 但係 ch3 會跟條 V尾行! 你係唔係有等二種連接方法呢?

頭先落epoxy既時候,條線真係訟左出泥! E 家想燒返落去都冇可能啦 :cry: 救命呀!!!

HI! MAK, 我誤會左你的原意,如果你是需要多條ch控左翼,咁應該張左翼servos插入ch3再做以下步驟:

1) mix1 ch3 to ch3 +/-100%(完成後ch3只會停係中位)
2) mix2 ch1 to ch3 +/-100%
有時間試下喇一定得 :D

Hi 佐治,
我點都 set 唔到 ch3 停係中位,推條 throttle 上去,條 bar 就由中位開始跟住上!
如果推到中位唔繼續推就得,但係咁會好難飛 :(
你個 mix1 D 設定係入勿野設定?

又得左啦!
今次多得佐治係深夜一點鐘都幫我set個發射。
今次隻1米DLG机點都要整好泥出賽,以報答大家既熱情指導 :D

Mak,

I use "wrap wire" to solder the IC pin then solder to the connection wire. Use hot glue to fix, which is quiet easy to remove for repair.

近日想整番好隻Mininch,但手頭上又冇6CH接收,於是將4CH改裝。但又唔想拖多條線出嚟咁唔reliable,所以將Ch3 cut咗改由Ch6出頭。嘩!焊條線落個IC腳真喺唔容易,我年紀老邁視力哀退,睇都睇唔清楚,點焊啊,好彩抓來一個放大鏡再加上我個女女幫手至搞得掂!而家多咗個6CH接收用囉,真是多謝各位機友提供嘅猛料。

嘩﹗真係叻仔另女﹗ 咁都比你諗得到,唔想要既野掉左佢,想要既野加落去﹗服﹗真係,我地滑機友果個ch3插都真係未用過,家陣知點對付佢喇﹗多謝提點﹗

HI!大家好我有小小個人建議,如果ch3真係唔需要用的話,可參考上次亞麥set隻Art hobby DLG用mix解決此問題,同樣將要用o既CH插落ch3到但係就唔洗拆開個殼焊接入面咁仔細o既零件,詳細數據無係手(我重係公司),亞麥記唔記得 :?

啊麥可唔可以講吓你點樣set到條throttle棍disable咗和ch1 mix 咗 ch3後嘅功能同用flaperon (ch1 + ch6)一樣。

以下係佐治教我係 Futaba 9C 做既 setting.
佢同 ch6 唔一樣。不過就好方便。

ProgMix1 :
Thro->Thro
Rate -100% -100%
Offset 50%

ProgMix2 :
Aile->Thro
Rate -100% -100%
Offset 0%

ProgMix3 :
Rudd->Thro
Rate -50% +50%
Offset 0%

Sorry, I think ProgMix3 should be INH (not used).
That will make ch3 mirror to ch1.
ch2 and ch4 should be used as normal.
