標題: 已经不是新车的XPRESS MRR2
买回来是已经装好的，过年前去室内场试车的时候跑了半天都不顺，回家才发现前轮Caster竟然是往前倾的……立刻拆车重装……
前天再去室内场跑感觉好多了～哈哈～动力是EC POWER 60A有感无刷电调+8.5T无刷，4000KV吧，我就完全够用了
感觉此车前上臂结构优点是不用更换零件就能调整Caster角和Camber角，但是这样完全通过推杆调整的话一套调车尺就必不可少了。
还有担心的就是这结构的强度，怎么看都觉得不太放心，不过跑了两次经过我几乎上20次的撞车还没有损坏零件，心满意足了……

今晚还把M04的防撞海绵DIY上去了……

真混乱的布线……

师兄在哪裡车场玩?

作者: SRGOD 時間: 2009-2-7 21:59
我響深圳南山個室內場玩，賽道掉頭灣比較多，場地有時會噴下糖水，所以好咬下。依家頭彈簧換左田宮M車TRF避震配果對白身黃標的彈簧，后面用Xpress原裝果對，車頭軟車尾硬的設定，感覺入彎系比較靈活，但仲未夠時間試出有咩副作用之類的。仲研究紧甘噶场地应该点SET部车好

C.hing,
HOw big is the Pinion gear you're using in 8.5 TURN ? I feel the car very NOISE when Im using the ECpower ? Is that normal ? And the ESC cannot use 100% Forward speed , I turn it down to 65% speed only..... but the speed similar to 23Turn

THKS.

I use the SpeedMind 64P 30T gear. And I think my car is not quiet too.

Why don't you set the ESC 100% forward speed? Is the ESC have any problem?

IF I set it 100% forward speed , the Belt seems flying...and the car cannot push forward ,because the speed of the motor too fast ... HOw about you ?

I use 64 pitch , Original Spur gear and 40T pinion gear, is that match ???
This car really NOISE

40T is ok for 8.5T motor. I use 30T pinion gear 100% forward speed and the car accelerate very fast.
Maybe your belt or ball diff have some problem? like the ball diff is too loose? Or try to change a new belt

作者: SRGOD 時間: 2009-2-28 03:46
Don't forget the Ball Diff Grease

作者: raymen 時間: 2009-3-3 20:51
師兄,你覺吾覺轉向比較差?
較得太盡,前面兩個轆又會磨到底板辺, 較得太開的轉向度又吾足?!

作者: raymen 時間: 2009-3-7 15:04
May I know what brand of the Li-Po battery U're using now ? The Maximum is 25C or 30C for the EC power ESC ???

Thks......

作者: SRGOD 時間: 2009-3-8 00:52
轉向我覺得都夠用啊，我較到轉到最盡車胎離底板仲有3mm。試下再SET Camber 角同Caster 角應該可以有幫助
