the lehner 1930 and bk9918 esc - Page 3 - RC-Monster Forums

Thanks guys I'll be running the t4 along with the 1930 and the 9918 to day at my local track on 7 cells and i'll see how it will behave. I have also equipped the t4 with an ACER RACING ceramic kit which I think is a very good step to bring out all the power from the motor or most of it since it's times and times better than the stock bearings and much smoother.;)

Here's my report about the T4/1930 5 turn motor and BK9918 controller: - VERY POOOOOR ACCELERATION.
- VERY LOOOW TOP SPEED.
- BATTERY GETS DRAINED OUT IN LESS THAN 5 MINUTES.
- THE MOTOR GETS HOT TO SOME EXTINCT
- I'M VEEEEEERRRRYYYY DISSAPOINTED.
- I'VE ONLY GOT THE CHANCE TO DRIVE IT ONCE CUZ IT SUCKS. IT REALLY DOES.
- COULD THE PROBLEM BE FROM THE BATTERY?
- COULD IT BE FROM THE 9918(WHICH DIDN'T GET HOT AT ALL WHEN I DROVE THE TRUCK).
- GEARING PROBLEM?( I'M USING 20T PINION/87T SPUR)
- COULD IT BE FROM THE MOTOR ITSELF?
- COULD YOU PLEASE HELP ME?

Easy does it mate, i understand your frustration, but easy does it, every single time..

What batteries are you using? Lets start with that.

No binding? the whole drivetrain runs freely?

I have a lehner 5300 on a 9918 I got from Mike , installed in my bandit. It absolutely screams on 8 cells. It should be comparable to your T4. I run gearing around 25/81 with incredible take off speeds and top speeds 50mph+ on this gearing.

How many cells are you running? If you are using the BEC on the 9918 you should at least run 8 cells and no more than 12.

Also answer serums questions. It really sounds like a battery issue.

Guess he's out testing it.. ;)

Enjoying his 60mph + T4, leaving us with his capslocked story...

:D

I'm not testing it outside or something its there inside my tool box sleeping like a stupid bear. ARRGGGGGHHHHHH. I just dont understand why? this motor can inflect icredible damage upon my drive train, but in reality its just like 19 turn brushed motor with no acceleration at all. I'm using a 7cell pack 3300 gp and my drive train is smoother than any skin you've ever touched in your life. I'm using Acerracing ceramic kit too.

Did you learned the 9918 the setup of your transmittor/receiver?

captain harlock · 04.07.2005, 10:38 AM

You mean programming it? yes i did

Serum · 04.07.2005, 10:43 AM

I don't know it either. did you tried another batteriepack? (last option in my bag...)

captain harlock · 04.07.2005, 10:47 AM

This same pack was tried in the t4 with the 1920/8 motor and it was really fast and good.

RCcarnut · 04.07.2005, 10:55 AM

Do you still have the 1920/8 motor? You could test that on your 9918 and rule out the motor as the problem.

Also I would try an 8 cell pack if you are using the controllers bec . Do you run a receiver pack or use the bec?
