Is there any c-hing running 12 son by 1s lipo without booster??
Cause I would like to buy 12 son but cannot find booster in KWS

Novak Booster on 1/F.
Another option is to use receiver pack.

c-hing could you please tell me what is receiver pack??

作者: hardmankam 時間: 2009-12-15 16:26
a receiver pack is a separate battery pack to power the reciever and servo. So the main battery (1s lipo) will only power the motor via the esc.

icic, that is the one we used on GP RC car.
thanks

作者: hardmankam 時間: 2009-12-15 16:31
a receiver pack can be:
a) 4 cell NIMH (4.Bv)
b) 2s lipo (7.4v) may need external bec to down to 6v
c) 2s a123 (6.6v). this is the best because its small and light.

Why use 1 cell lipo with booster?
Why dont use 2 cell Lipo directly?

作者: hardmankam 時間: 2009-12-15 18:04
1S lipo on 1/12 seems to be the future legal racing spec.
but i agree, 2S is more simple than 1S

Can I use 2S on R5? If yes, which one should I buy and where to buy??

作者: hardmankam 時間: 2009-12-16 01:15
yes, some 2s-lipo will fit the r5. my friend used 7.4v 1800mah GE brand. you can buy it at KWS. i think it costs about $120 each. Just pair it with 3000kv to 4000kv motor. the speed should be pretty fast.

Very good suggestion & want to try....
Can I know how many minutes it can be played?

Thanks All !!

作者: swswsw 時間: 2009-12-28 16:18
9minutes with 4000kv motor + 1800mah Lipo -> end voltage 7.6V

作者: yokomo 時間: 2009-12-28 17:22
Thanks C Hing, Very gd news.... ..

Booster is available at cat shop

又唔用 Novak SMART BOOST 1-CELL LI-PO STEP-UP MODULE (升壓 MODULE)

唔用接收電 -- 1:12 Pan Car 1S LiPo 電應該 3.7V 1S 有呢隻好用

我用好盈60A電變配5.5T摩打駁1S鋰電, 加咗 NOVAK BOOSTER 後行唔夠一分鐘就節電(設定是3.2V)而且車速很慢, 請問是否要用埋對應1S鋰電的電變先玩得呢?

作者: hardmankam 時間: 2010-3-15 10:00
回復 19# 湯瑪仕

Can you set the voltage cutoff to a lower voltage? (or disable cutoff)

作者: chestertai 時間: 2010-3-15 10:26
if using booster, with ESC switch off, booster on, then voltage cut off should not kickin. Which I confirmed with LRP SXX.

作者: 湯瑪仕 時間: 2010-3-15 21:12
原來唔駛著電變, 多謝 CHESTERTAI 帥兄指點!

作者: 湯瑪仕 時間: 2010-3-16 08:04
但係無著電變就無節電功能, 舊電會否因過放導致死電呢?

作者: 湯瑪仕 時間: 2010-3-16 12:48
咁有乜辦法可保障舊電唔會過放呀?

作者: hardmankam 時間: 2010-3-16 14:44
When the car is slowing down, stop playing.
or
after 7-8 minutes, stop playing.

作者: r003 時間: 2010-3-22 17:00
i dont think using 1 cell with booster is a good idea.

作者: hardmankam 時間: 2010-3-22 18:19
using 1S + receiver pack is better

請問師兄如果我用receive pack A123 6.6V
ESC SXX,1s lipo,futaba 604FS接收。
1.須要開電變開關嗎？
2.A123 充滿電會超過6.6V ,對接收會有影響嗎？

作者: hardmankam 時間: 2010-3-23 02:43
1.須要開電變開關嗎？
--> esc can be 'off' (but not 100% sure)
2.A123 充滿電會超過6.6V ,對接收會有影響嗎？
--> When fully charge, 2SA123 is about 7.4v so it is slightly over voltage. It should be 90% safe to servo & receiver. but you may add a voltage regulator to drop it to 6.0v to be on the safe side.

作者: mschumi 時間: 2010-3-24 02:26
receiver pack A123 200mah 6.6V
BEC to 6V

作者: mschumi 時間: 2010-3-24 03:17
有無人知依舊 200mah 可以玩到幾多排電哩?

作者: hardmankam 時間: 2010-3-24 22:43
200mAh about 2-3 packs.

作者: mschumi 時間: 2010-3-24 23:12
thx!
玩 2 packs义一次,又或者買多pack 咪OK law

作者: hardmankam 時間: 2010-3-25 14:39
I think 2S123 @ 6.6v (or 7.4v charged) can plug directly into the receiver without problem. Some people even plug in 2S lipo directly. Also 5cell NiMh full charged will be around 7.2v and people has been using 5cell NiMh as Rx battery for a long time without problem.

Of course with a 6V regulator is the best, just a little bit bigger/heavier.

請問用receive pack ,esc 開關唔須要開，
敢點set ESC 既中位呀？
定係插左receive pack 個ESC自己會著架？
然後就可以set 中位及set program架？

作者: hardmankam 時間: 2010-4-21 14:13
Not 100% sure, but I think you can connect in 2 ways:

1) ESC Off, RxBattery plugs into Rx.
2) ESC On with red data cable taken out (this will disable the internal BEC), RxBattery plugs into Rx.
