美國飛友Silverstreak328
在國外專業模型網站發表對T-REX450XL(CCPM)組裝心得~分享
配備:
Align 420LF3200KV
Align BL-25T
Hitec HS-56X4

It's finally here! A CCPM version of the T-Rex from Align . I will be reviewing the new version of Aligns new micro helicopter the T-Rex 450XL CCPM.

First impressions: The box is bigger! It looks a lot better in black and the color scheme of the new helicopter shown on the front looks excellent aswell.

作者: DEDE 時間: 2005-6-13 00:35
I quickly found out why the box was bigger, Align has packaged the helicopter with a very nice aluminum case! It's not big enough for the assembled helicopter to fit into, or even a controller but I know I'll find it great for storage of accumulated heli stuff. I haven't checked yet but I believe a micro heli such as a aerohawk/hummingbird will fit into it. Another plus is that the inside is lined with foam padding!

作者: DEDE 時間: 2005-6-13 00:37
The kit I received also came with Aligns new 3200kv 420LF brushless motor and the new 25 amp RCE-BL25T brushless controller. The kit is well packaged and the metal case should protect anything from getting bent or broken during shipping. The kit comes with 2 sets of blades, 335mm wood blades and the yellow abs blades for beginners (easier to hover with). I also noticed that the R48 glue is now in a sealed bag so there won't be any more leak issues that some have experienced in the past. The kit also comes with a extra parts bag filled with a couple of every piece of hardware such as screws, ball links, washers, etc. As always you get a nice little tool kit to build the kit with.

Next up is the assembly

作者: DEDE 時間: 2005-6-13 00:44
For the electronics in the heli I will be using the following:

Align 420LF 3200KV brushless motor
Align RCE-BL25T 25 amp brushless ESC
Futaba GY240 HH gyro
Berg 5 DSP II Rx
4x Hitec HS-56B servos

Assembly:

First I started examining each of the parts bags getting familiar with the kit. Each bag is nicely labelled and corresponds to each step in the directions. I noticed while building the head how everything was fitting together much better. Every joint and rotating piece had ball bearins in it! Instead of previous kits where you had to torque the screw down and check for friction each time , now you can just torque it down snugly and it rotates freely without friction! Awesome . On a few parts there were "burs" sticking out from the molds but you can quickly trim these off with an exacto knife.

作者: DEDE 時間: 2005-6-13 00:45
Assembly of the head went well and I was very pleased with the design and how frictionless everything was.

Time came to put the flybar paddles on. I got out my trusty scale to weigh and balance them.

First blade was 5.06 grams

作者: DEDE 時間: 2005-6-13 00:46
And the second was 5.31 grams! That's .25g more

作者: DEDE 時間: 2005-6-13 00:48
I had to attach six ~1 inch long pieces of scotch tape for it to match the other blade in weight

作者: DEDE 時間: 2005-6-13 00:49
Head with FB blades on and main gear for test fit.
I highly recommend weighing and balancing as much as you can on any heli kit, it may not seem like much but at 2400 RPM's it can cause a high frequency vibration that can greatly interfere with gyro performance

作者: DEDE 時間: 2005-6-13 00:51
Assembly part 2:

(I got ahead of myself guys and finished the heli . I'll still go through the review as best as possible.)

After the head assembly I started assembling the main frame. Not much has changed here. The area where the pitch slider used to be now has two bearing holders for the rear CCPM link. They simply fit in the existing slot by friction and with the cap/servo link connected two screws hold it securely in place. It also moves very smoothly due to the ball bearings here too .

Bearing holder circled in red.

作者: DEDE 時間: 2005-6-13 00:52
Obviously the servo cage is new. It feels a lot more rigid and reinforced than the previous one. This also could be because Align claims the new black plastic is both stronger and lighter!

One important thing you will have to do on the servo horns is mount the TOP ball link on the inside of the horn. If you don't do this then the body of the helicopter will rub when installed. The Align instructions say you "May" have to do this but I don't see how it would work if they were on the outside. Even with the ball links on the inside and shaving the servo horns down a bit the left CCPM servo (the red circle on the right side of the picture) still slightly rubs the body but not enough to be concerned.

You can see them circled in red in the following picture

Other small changes on the main frame are reinforment braces at the rear just under the tail pulley and at the front behind where the battery sits.

作者: DEDE 時間: 2005-6-13 00:54
Assembly part 3:

Tail assembly, the tail is not much different than previous ones in the way it is put together. Instead much of the parts have been "optimized" for less slop and less friction. The tail slider is especailly good. It also has ball bearings in it to make for very smooth movements. The "fork" is a much better design aswell, it holds the tail slider at both the top and bottom!

Tail pitch slider:

作者: DEDE 時間: 2005-6-13 00:56
In addition to holding it in two places instead of one the slider is also allowed to "pivot through the fork" slightly as you can see in the picture above. This puts much less strain on the servo operating it.

A nice finish on the tail is the vertical stabilizer. It is made of CF (yes real cf, not the fake stuff ) and looks very nice mounted on the back.

Rear tail rotor:

The rest of the tail (horizontail stabilizer, supports, servo brackets, etc.) go together exactly like the previous T-rex kits

作者: DEDE 時間: 2005-6-13 00:57
Assembly part 4:

The electronics were installed as Align recommends in the manual. Originally I wanted to mount the gyro inside the frame for better protection but the BL esc/motor would be too close to the gyro and be susceptible to interference.

For the servos I had to drill center holes in the HS-56B mounting tabs. The 56B's come with 2 holes on each tab at the corners instead of one in the middle.

作者: DEDE 時間: 2005-6-13 01:01
The Align RCE-BL25T is zip tied to the bottom with the heatsink facing downwards for airflow

作者: DEDE 時間: 2005-6-13 01:03
I attached the translucent window with two screws at the top and bottom rather than using CA to glue it on permanently. To make the small holes I simply heated the tip of a paper clip up over a candle and then melted a small hole with it in the plastic body. It came out well and holds the window on very securely

作者: DEDE 時間: 2005-6-13 01:04
And now the completed helicopter　

作者: DEDE 時間: 2005-6-13 01:05
Final Thoughts:

This new helicopter kit from Align is a very nice kit! Everything fits together very well and many of the issues from the past helicopters have been fixed. I really like how it is packaged with the metal case etc and the new color scheme on the heli is easy to see when flying, very attractive and sharp looking.

Almost every rotating part has ball bearings in it to make rotation silky smooth and slop free. The addition of a eCCPM setup is even better. This helicopter is VERY sensitive to any inputs while flying, I had to turn down -50% exponential or it was way to jerky for me.

For the pitch range on this heli i am getting +14 to -14 which is quite good! The new ball links are not too loose and not too stiff, they eliminate much of the sloppiness of the older links.

I must say I have not had much time to fly this helicopter or push it hard in some aerobatics, the weather in Florida has been horrible this whole week. I did get a couple flights in the other night and from what I can tell it hovers like a champ! I first tried it with the the yellow ABS blades, they hovered quite well but cyclic reaction was dampened. Put the 335mm woodies on and it's a totally different helicopter! Cyclic inputs react faster and climbout is excellent on TP 3s 2100 MAH lipos. For some reason the yellow ABS blades have the stickers on the bottom, still can't figure that one out .

+ CCPM helicopter kit from Align
+ Cool aluminum case!
+ Instructions are easy to follow and all parts bags labelled
+ New head is much more precise and slop free
+ Good price, you get what you pay for
+ Head balance "wobble" issue is fixed
? Why are stickers on bottom of yellow ABS blades (look backwards)?
- Not a beginner helicopter, CCPM setup can be confusing
- Computer radio for CCPM mixing is required

老外做事情真是鉅細靡遺
佩服

感謝 DEDE大大分享
這篇真是很有參考價值

不過看來原廠真的還有改善空間喔

作者: mikado086 時間: 2005-6-13 01:14
公仔還是在正面用個絹印的 ALIGN Mark，這樣大家才不會一直 Why..

把 Mark 印在接近旋翼頭的地方，這樣比較不會有不平衡的問題

作者: DEDE 時間: 2005-6-13 01:19
pico版大

我想公司明天會針對Silverstreak328的平衡片為何會有0.25g差異作檢討
謝謝!

作者: pico 時間: 2005-6-13 01:26
不過講了這麼多
好像只有這一個小小的缺點
算是好事吧

但是這個小缺點算得上是重大的問題喔
塑膠射出應該不至於有這麼大的出入
會不會是塗裝的問題

有問題改善了就越來越完美了

這個why會有那麼多飛友提出!!是我比較意外!

槳貼紙!貼於下面是延用原黑色碳纖設計而來!!!那時就沒有why

想想可能要如您所建議!正面非印個ALIGN Mark素不行啦!

XL版『WHY』的問題小弟還是在最後上主旋翼時赫然發現，怎麼新版是『逆槳』XL版改這麼多呀

後來才發現，原來是貼紙是朝下貼滴………

詢問各方高手發現，這種貼法才是王道！！

理由是飛3D才知道正反

好像也蠻有道理的喔！！

本來 QC就是只能抽樣檢查
東西到消費者手上有問題也不是誰願意的
這沒有什麼心態的問題吧

人家發表的心得也說啦
很多原先舊機型已經發現的問題也已經有改善了

既然已經發生了原廠也表示願意檢討改善了啊
不知道大大有沒有更好的辦法
也歡迎給原廠建議囉

這樣後來買的飛友拿到品質更好的產品

不過這個問題雖然是個瑕疵
飛友也是可以自行修正的

已經購買的消費者可免費郵寄回換新阿

作者: pico 時間: 2005-6-13 19:58
可以參考一下老外是怎麼做的
而且這個瑕疵並沒有列在他的結論裡面
人家就是貼了一塊膠布就解決了
0.25g 其實塗裝的誤差一點點就有這個重量了

對原廠而言這是一個抓到產品生產運輸到消費者手上
到底會有些什麼問題可能發生當作品管的參考
當然也要有這麼龜毛的飛友才會真的拿來秤
而且精密度到這種零點幾克的計較
放輕鬆啦
這種誤差貼個膠布就可以解決了

反倒是主懸翼的貼紙提出來討論

不要強迫我做功課我英文學得不好

我強烈建議任何直昇機的套件都要量一下重量並且儘可能做好平衡
也許他看起來不是那麼大的差別但是在2400轉/分的轉速之下將會產生高頻的震動
這可能會對於陀螺性能造成很大的影響

123大則兼顧了未來的文法(人不是你殺的)以後的人,說話也許會像電腦一樣!
(現在常上線的人,已經慢慢開始有這種傾向)

不過話說回來!
主旋的平衡問題,在這兒真的上了一課!
我們總會忽略一些小地方,而影響整台機體的平衡!
要神乎其技,相對也要有職業及的調教~!

我的翻法是

我強烈建議對任何一組直昇機套件盡你所能的秤重與平衡
看起來可能沒什麼大不了
可是在2400rmp時小小的不平衡會造成高頻率的震動影響陀螺的效果

英文如果逐字翻譯沒人看的懂說

小弟以前幫住外代表處翻過文章通常才幾行英文叫要翻成一串中文說很累的

作者: 電動漢堡 時間: 2005-6-14 11:42
看來,如果有天平加上動靜平衡儀,那就理想了~!

像偶們公司用的32000轉刀桿,旁邊都會鑽動來作平衡,
用意就是確保加工精度,與主軸長期使用的壽命!

這個Silverstreak328飛友真蠻囉唆的, 他還有提出這個:

Important update!

I have recently found there is some friction in a part of the head that lets the flybar "seesaw" back and forth. It isn't a critical thing but after fixing it I found it hovered even better!

The part is circled in red in the following picture:

What you need to do is roll some 600+ grit sandpaper into a small roll/tube and lightly sand the inside outer edge of each brass fitting. If not the screws that go into the brass fittings will cause some friction! Keep test fitting the screw in each until there's no friction!

其實我覺得還好啦,畢竟降低所有連動機構的阻力,對機子的反應及穩定度都會有正面的幫助!!
況且措詞都還蠻中肯的,比起國內少數飛友來說真是天壤之別!!

或許在國外沒辦法像在國內一樣,拿著雞毛當令箭,找到一樣小毛病(有時候還是自己的疏忽),就準備利用網路的討論區當工具進行變相勒索....

可是這也是樂趣不是麻
