Brushless Advice

[Nick]

10L & 9918 it looks like then. :D

Thanks alot, just need to order another pair of cells and an extra 2 to jump to 16. Then some differentials/CVDS and stuffage.

UBEC too, I heard this can cut runtime? But then I really can't be botherd having more cells in my truck to power things.

Can't wait to go Brushless, know someone who thinks hes unstoppable with a 18.97KWF and Hacker B50(10L) on 16 cells - now I can compete. :D

Ubec doesn't take that much. you probably won't notice it.

are you planning on mixing used cells with new and unused cells?

[Nick]

I will be buying a new pair and make a fresh 2x 8cell packs (3600s).

Then buy 2 more new cells to go on my current used 3300s.

None are matched.

*Update*

I have thought about a brushless setup further, and thinking of just a 14 cell setup instead of 16, my reason being a want rid of the hump pack, to avoid batteries falling out, which I truely think is the problem and don't want to discuss that in this thread again, lol.

Is it possible to get the same sort of performance of a 10L using 16 cells with 14 cells and a different motor?

Or should I just go for the basic 9L?

[RC-Monster Mike]

The 9L on 14 cells will be similar to the 10L on 16 cells. The 16 cell setup will always have potentially more power, but with the same gearing, the 9l and 14 cells would be right there with the 10L and 16 cells.

[Nick]

Whats the Lehner equivalent? How would it be in comparison to the 9L?

[maxxdude1234]

The 2800XL is the closest to the 9L. The 2 are pretty much identical, but the lehner is more efficient (maybe a tiny tiny bit quicker).

[RC-Monster Mike]

Xl2400 or xl2800 would be in the same power output range. The Lehners get a little better runtimes ans slightly faster acceleration, but the performance is very close.

[Nick]

You mentioned the XL2400 for 16 cells too, is this faster than than the XL2800 then, or more power?

[RC-Monster Mike]

The xl2800 is fatser, given the same cell count and gearing. the 9L under load would perform somewhere in between these two motors.

[Nick]

I guess the XL2800 is the "Basic XL2800" which you mention?

I noticed most brushless motors have 3 wires, whats the 3rd extra one for?

[Serum]

Yes, it is the basix XL2800.

The three wires serve other purposes than with brushed. You need three of them, to make the whole magnetic field fly around the magnet, pushing it forward. It is the princple of the Mono-rail magnetic field train. That is the reason you need a fancy controller as well.

here, check this;



It is a 4 pole, but the goal of the three wires stays the same. A 2 pole brushless motor has got 2 poles on the internal magnet. (N+S)

Mike u seem very familiar with the lehner motors.
can u tell me the difference between a lehner basic and a lehner basic XL?

[RC-Monster Mike]

The basic xl is about twice the size - better for monster trucks!

[Serum]

the basic is nice for 1/10th cars and 2wd smaller trucks. (or a lightweight 4wd buggy)
