BK Warrior Update!!
 

I don't know if this is interesting for our american members, but anyway:

BK offers to upgrade your Warrior for only 50 Euros! On their site they say they will turn a 70 amp Warrior into a 99 amp one, or a 99 amp into a 120!
For extra 50E they will turn a 70 amp Warrior into a 120 amp one.

Not bad!
I'm thinking about sending them mine.

DAF

hmmm.....sounds good. I might consider upgrading my 7020 to a 9920. Does it matter if its used etc.?

They say you send them your used one, and they will upgrade it.

Apparantly its only for customers in germany, shame. Nice idea though

that sucks! what i really need is a 36 cell controller and not a 120 amp thought....

hmm, do u guys know any friends in germany? lol. How do they change the amp anyway?

Extra capacitors?!! probably other few things, too. The 70 has only two and the 99 up to the 150 both have 4 capacitors.

I disagree harlock. The new 9920 have 2 capicators to. The 9920 has 2 boards and the 120 has 3 boards. The 7020 has 1 board in it. I would say they add a board or 2.

I think it has something to do with the fets, but they may add a capasitor or two to help with dips in voltage

Correct. FETs determine the amperage capability for the most part (the circuit board(s) also need(s) to handle the amps). Another capacitor would help to smooth the voltage spikes with the addition of more FETs.

Thanks MetalMan. that was something i learned about brushed controlers, that i was sure was similar to brushless.

What about a beat to hell, non-functioning 7018......think they'll do anything to that for cheap? I'm planning on getting a Mtroniks Genesis Pro when Hobby People gets them, unless I can find another good controller for $120 (discount price of the Mtroniks basically).
