It's all good, I wasn't trying to be mean or anything. Joking about the whining part, I just threw that in there |

[quote=toy4crawlin;1436408]So you guys are saying for those folks running Berg and 35t or 45t motors that the FXR is not recommended or will fry and we should buy a 2nd or a FXR pro So whats the Verdict on this |

If you are running a berg with anything higher than 60x1 you run the risk of damaging the ESC. Last edited by kaetwo; 11-20-2008 at 09:06 PM. | |

EDIT: There are so many Bergs running 1 FXR How can that work so many are running just one I was not smart and "assumed" one was good. That's why I always asked even silly questions oops, didn;t see it Thanks Ty & Scatman Looks like a return to TCS You mean Lower Kaetow Last edited by toy4crawlin; 11-21-2008 at 11:05 PM. |

for you that didnt understand that "ripple effect" here you go The multiphase buck converter topology also has more packaging advantages than just the reduction in the number of input and output capacitors. Each channel is converting power at a fraction of the conventional buck converter, which will reduce the size of the inductors and power MOSFETs used in the design. SMT inductors can be used along with SMT power MOSFETs (SOIC-8 package), resulting in a low-profile design. A multiphase buck converter designed to stepdown a 5-V input to 1.65-V output at 50 A has demonstrated a power-transfer efficiency of more than 80%, eliminating the need for heatsinks. so there you have it in a nutshell why the capacitor is needed and it needs to be as close as possible thankyou tekin for the lesson | |

What are the specs on the capacitor? I've broken off one of the legs, it has just enough left to allow it to be soldered on but I'd like to replace it.

Just wondering why ppl are so quick to bash tekin for putting the cap outside of the box? Seams to me that the Rooster Crawler is the same way but noone complains about it...could it be that because novak soldered it on for you it makes is ok? Just my two cents |

| As I was reading through all these posts I was thinking the very same thing about the rooster and goat I have. Cap is outside on them too and they are WAAAAY bigger footprints AND overal size.

i have my bec conected and when i plug mine in to hotwire it doesnt do anything... it still says to plug it in.... is it because my bec is on it? i got it from someone and they disconected one of the wires so the power goes to the bec.... is that it?

Does the BEC power up? Your usb may not have enough power to boot both up. Try plugging a battery pack into the fxr.

Whenever I hook up the hotwire I have to reconnect the red wire that goes from the esc to the rx plug, which was disconnected when the bec went in. Hooking up a battery might work too, I think it just needs to get some power to the esc.

The FXR may only use a 2 cell LiPo. the FXR Pro only may use a 3 cell LiPo. at least thats what the spec sheet is telling me. I was using a 3 cell on my FXR and it would glitch out and go full throttle after a minute or 2 of driving. then i went down to a 2 cell and the problem cleared. | |
