LAZER RTR

請問 各師兄, LAZER RTR 個原裝電變 頂唔頂到 lipo 2 cell ?

dont use lipo on it~~~ it will burn very easily.......

今天去買(壓電片).跟一堆其他件.d廠好浪費.

not  waste in their point of view because it is YOU ( not them) who pay for the extra material and parts which is no use . .. . .

真係!?
因為上星期見友人係TRC玩得好開心(LAZER RTR+LIPO)
用原裝電變,原裝MOTOR~~

唔多覺~~但唔明點解舊電會令到個電變燒 ~~~ 可否解釋一下..

NiMH is 1.2 x 6 = 7.2V and Lipo is 3.7 x 2 = 7.4V 因 lipo 電壓是比 nimh 高, 所以有d 唔放心個電變頂唔順 .. . .. ( nimh & lipo 充滿後都會再高d 的 )

計落又好似係呀 .... lipo 差滿 8.4v .... nimh 差滿都不過是 9v.... 個電變一定頂唔順 lipo
千期唔好 full 雞呀！慢慢行... 或者鎖入夾萬唔好玩就最好 ...

我 full 左一晚咋，唔好信我呀！

Hi all 師兄, before I read the reply from byron.c I have tried to run my LAZER RTR with a pack of 2S lipo. Below is my running report :

1. I checked the Lipo voltage before testing = 4.1 + 4.1 = 8.2V ( LIPO fully charged 3 weeks ago...... no time to play)
2. In the beginning, I only run at half or 3/4 throttle.
3. then I full the speed is not very fast, so I tried full throttle and speed is ok but still not fast.
4. after 3 ~ 5  min running, I check the temp of the ESC ( only a bit hot), and motor (only a bit hot), but the motor connector to ESC is hotter than I expect.
5. I keep running for another 3 ~4 min, over 1/2 of the time is at full throttle.
6. Then I check the temp of ESC ( still a bit hot only) and motor ( hot, but less than I expected.) and the motor connector to ESC is the hottest among 3.......

I tried the above test in the open playground of Olympic city 2. I did not bring the lipo voltage tester last so I dont know what is the lipo voltage at the end of the test but i would say the speed did not drop when compare to the beginng.

In the view of the above test, I would say it is OK to use Lipo to run the LAZER RTR but should change the T plug for motor & ESC connection......
Hope the above test is useful information to all brothers.
