無刷馬達數位伺服機

jkhung888

請問這顆伺服好不好--Futaba BLS451 無刷馬達數位伺服機,
又有這個Ni-Cd USE only註記,
有這麼嚴重嗎?一定要鎳鎘,
這好像是首顆可以用在90油機的無刷伺服,
但不知風評如何?
謝謝.

日本標示Ni-Cd的用意
其實就是表示了這是個耗電量比較大的伺服機
用鎳鎘電池才不會有太大壓降

其實鎳氫電池的表現也不錯
只是到了後段時的放電曲線表現比較差
所以原廠直接標示著鎳鎘專用

現在如果用BEC則是沒這些問題了
直昇機我建議用5A以上是最為保險的

我現在大大小小的油直都用亞拓新款二合一
方便也好用

最近我有拿到一顆也是國產的15A測試樣品
正在用放電器測試中
如果跟二合一樣又帶點火該有多方便阿！

BLS-451有飛友用在T-REX 700N CCPM十字盤上，效果很不錯唷!!不過價格上不便宜，也可考慮亞拓DS-620或是DS-610!!請參考~~~

謝謝,
以目前的景氣,是應以亞拓為首選,
但610和620據說在國外的風評出現兩極化,
先別管無核或無刷,兩個應該都是台灣製造,
差別在於一個是台灣的QC,一個是日本的QC,
不良率的部份,兩者應該都有辦法控制在合格的範圍內,
但在QC觀念的不同,日系產品在品質的穩定度和耐用性更勝一籌,
相對成本高,售價也高,讓我再想一想.

Dear 大大:
我看了你的留言說國外對DS610這顆的平價反應很兩極 所以上網google了 一下
在應該算具指標性的Helifreak論壇上看到 都是正面的ㄝ

擷取幾段給您做參考

I've used them on my T700 for about 30 flights and a flying buddy been using them on 8V on his 700 for about 50 flights - so far so good - I tortured one to death on Bob's Tech room under using CBDANES servo tester

IMHO these servos gonna do to Futaba/Hitec what the T600 did to the Raptor 50 !

主要是說這位玩家用DS610在他的TREX700上已經飛了30趟 他的飛友甚至用8V的來飛 也已經飛了50趟 so far so good (到目前為止都很好), 他用CBDANES 伺服測試機把一顆折磨死了 (我也不曉得他沒頭沒腦的說這各幹麻)
最後是說 IMHO (In My Humble Opinion)照字義上來翻是 我個人的淺見 這幾款伺服會對Futaba和Hitec造成 Trex600N 對 Raptor 50的影響 (至於是甚麼影響 大家各自發揮囉)


以下為另一飛友的po文

I took a look inside and the circuit board and solder joints are well made. no sloppy work at all. ( I used to work for SONY electronics in greensburgh PA.) I know a good solder joint when I see one. definetly recommend these servos. and as far as I'm concerened this post will probably never get old. only more popular....:-) Any further update on these servo?

I'm not even sure how many flights total that is ( lost track ) , but I'm well over 70 now with 2 crashes. no signs of wear, they center perfectly and now I'm thinking about buikding a second 600E soon, as a back up for when I go to air shows. I'm just affraid that the second one will become a shelf queen . the castle creations BEC's are the best inventions yet they perform very well even under serious load and have had no hick ups with them either. __________________ you will only crash so many times, before you get it right

tick77第一篇文寫到DS610的超值價格 並且拆開裡面看過 不管是電路板或是銲錫點都做的很好 , 他曾經在SONY 電子工作過 他一眼就能看出好的solder joins(銲錫接點) 他絕對推薦這顆伺服

後來隔了數天後又有另外的飛友問他 後續如何

他就po了第二篇文,內容如下:
他之後又再飛了23趟,他表示DS610是他用過最好的伺服.他說他也不曉得總共飛了幾趟了 但是他說他已經飛了至少超過70趟並摔了兩次 但目前伺服看來皆無耗損(wear)並且中立點還是很準 (center perfectly) 接下來就是在說Castle電變的事


以上給您參考!!!

目前我的450、500、600、700、F3A機
已經全面改用DS620原廠所製造的伺服器
能夠讓我全面更換....我自己也感覺蠻不可思議的
倒是換下了許多H與F牌伺服機～呵呵

經濟、耐用、速度快

最重要的是Mide in Taiwan啦！
