標題: 美國Steph對SPROT感想
I had a chance to build one and it certainly is a nice upgrade from the V2. I believe this is a natural evolution of the original T-Rex 450 series for people who prefer the belt tail and double stacked frame.

Here are some closeups and I'll note the differences from the original SE V2 kits.

Packaging is different. Since the Pro didn't get the nice aluminum box, this one didn't either. But the parts are individually bagged and stored in boxes as shown.

The head, tail and frame are pre-assembled and all screws had loctite (at least in this kit it did).

Here are some new designs:

The new head block is wider with similar spec as the Pro, and I believe sharing the same spindle shaft. mixing arms seems to have different geometry. two pairs of the links are pre-made one piece design.

The flybar support ends have been extended on the flybar cage. This is an effective way to stiffen up the flybar. And the kit comes with two aerodynamically efficient flybar weights.

The frame contains some of the biggest changes. While it's not as dramatic as the pro, these changes certainly are welcome improvements over the original SE frames.

We all know what sloppy battery can do to a heli in 3D. So Align redesigned the battery tray to make it more rigid.

The belt pulley assembly now rides on a platform which is part of the tailboom clamp. This effectively creates a very rigid structure, yet reduced the part count.

The motor mount has two slots which the top frame assembly gets sandwiched, and then compressed together with long machine screw. This removes the needs for front standoff posts yet increased the sitffness of overall frame. The back standoff are replaced with two aluminum machined blocks which fit perfectly with keyed frame.

The gyro mounting platform has also been reinforced. Stable platform is always good for maximizing gyro gain and performance.

The landing gear did not go with the one piece design of Pro. They continued the use of original design, but with pre-slotted holes for set screws to hold the skids in place. I hate using any type of glue here so this is a welcome change.

The tail gearbox has been strengthened and part count has been reduced. The bellcrank mount is now part of the gearbox. The weighted blade grips found in most newer Align kits are also found here.

The servo mounting tabs is one of the biggest improvements. No longer do you have to fiddle with the little plastic nut inside the frame where most fingers can't reach. The tab just slides onto the frame, and servo tightened down. This is a huge time saver. And in addition, the frame is keyed with a small oval hole as a reference to servo centering point.

As discussed above, the new outrunner motor is included. It seems to have a lot more cogging than the older design.

The canopy is slightly revised shape from the pre-Pro line. A lot of people prefer this style, but I prefer the stubbier shape of the Pro/250/500.

Just eyeballing the swashplate between the Pro and Sport, they look to have the same geometry, so I would think the frame can be interchanged. I personally like this traditional double stacker frame for wire routing and receiver access, but the single plate Pro frame seems more rigid. Of course there is no way for me to verify what is stronger, suffice to say either frame is sufficient for heavy stick banging.

我看了一下 PRO and Sport 的十字盤，它們都有近似的幾何設計及尺寸大小，所以我在想主體側板應該是可以共用的。我個人較喜歡傳統單邊雙片式的側板，可以容許接收器的線進出抽換。但是單邊單片的 PRO 側板設計似乎較堅固。當然以我的飛行級數是無法證明它們哪一個是比較堅固的，整體說來這兩款的側板(PRO & SPORT)都夠堅固了，可以承受一般的碰撞。

I have been flying the pro for a few months, and until I got this Sports up in the air, I almost forgot how quiet belt drive is. Torque tube is nice, but noise and maintenance is always on my mind while flying, so suffice to say I will be flying this heli in the foreseeable future. The tail performance is excellent, and to my surprise, the included DS420 servo actually held the tail extremely well. The heli felt very stable, yet comes alive very quickly on the cyclic. It has the same floaty precision characteristic of the Pro's head. Between the Pro and this Sports, my T-Rex 500 will probably become a shelf queen.

我已經飛了 PRO 有幾個月了，直到我拿到了 Sport 升空後，我幾乎忘了皮帶傳動有多麼安靜！軸傳其實很好，但飛行時的聲音和維持保養總是讓我掛心。所以在可預見的未來，我會以這台 Sport 為主要飛行器。尾翼的表現也相當出色，超乎我的想像， DS420 竟然可以鎖的這麼好，這台真的感覺非常穩，而且十字盤在打 Cyclic時也很敏捷迅速，跟 PRO 的表現是一模一樣的。相較 PRO 與 Sport，我的 Trex500 應該要當展示架皇后了。

The little outrunner motor is excellent, and dare I say it, better than the one in the Pro kit. Running Thunderpower ProPower 30c, there was absolutely no bogging at 11degrees + and -. But care must be taken when routing the excess wires, as I had one of the servo wire rub against the rotating can. Motor came down cool to the touch after 6 minutes.

另外這個所搭附的外轉馬達也是非常出色，搭配 TP30C電池，我敢說它的表現比 PRO 的馬達還好！行程設定在 11°+ & 11-° ，但是還是要小心，設定伺服器角度時不要過量，以免干涉，這是我的經驗。馬達感覺溫度不高在飛行了六分鐘後，還可以用手觸摸。

I love it!!!
我愛它！！！

多謝大大組裝心得分享，這T-REX 450 SPORT真是大進化...

作者: frr439 時間: 2009-7-20 21:32
裡面有寫到PRO跟SPORT的側版可以互相共用，是真的嗎?

到底可不可以呢?

sport... 真是又讓我心動了...... 景氣不好, coco不夠..

不好意思各位飛友  剛看了一下  對

他所說的這句話  有點百思不解

設定伺服器角度時不要過量以免干涉<---這句

不太懂是指哪一個的設定EXP?? EPA

因為最近  飛SE450  怪怪的  常常遇到  干涉的樣子

會NO控  但一下子又好了害的我最近飛的心驚膽跳

一直覺得是接收器的問題但也有人說可能是機械故障

最近摔兩次  都是突然無法動作  而摔機但斷電可以動作

所以我在想是不是我遙控器上面設定有錯誤  在遙控器上的EXP

有三個顯示  1 2 4  這三個我都設20%  (HITEC7動遙控器)

想請教各位飛友有沒有遇到我這樣類似的問題  另外我機上的三顆伺服式新買的DS410M

作者: slk320 時間: 2009-7-23 11:52
他指的意思,許多飛友不自知在設定十字盤動作角度行程(SWASH)與PITCH時過量,這種情況如果只打單動作可能沒事,但一旦有較大的幾個動作一起打時,可能會讓主旋翼機構打架干涉,下場就不用說囉!一定發生類似干擾的摔機

SOGA 謝謝飛友的指教!!

多謝SLK320翻譯.

其實我那段"But care must be taken when routing the excess wires, as I had one of the servo wire rub against the rotating can." 是指伺服機電線安裝時要小心, 離馬達要保持距離. 以前亞拓馬達都有外殼所以電線碰到也無所謂. 這顆外轉式馬達不能有任何東西碰到.

不過SLK320的指點也對. 十字盤過度角度是會造成干涉,甚至摔機. 所以要儘量避免.
