Ah, that good servo was a good idea then if you will run 5v instead of 6. Plus a high quality servo will last longer too. Probably a good purchase.

Keep in mind that as you raise the voltage and change to a more effecient motor the esc will most likely see a lower amp draw and run cooler. IU have found this and am slowly swithing over to lower kv motors and higher voltage batteries.

I used to have to run a fan on my MM (stock) with my 10l feigao on 4s lipo. I added a Novak Pwer cap (#5674 2700uf 25v) to the board where the power wires go in, and now I do not need the fan. My system is mild, but I had Griffinru mod a MM for me and it ran a 7xl in a 1/8 buggy that was geared for 40mph, and did not get hot even after a 40min run!

I like your idea with the heatsinks on both sides, it would be nice to be able to mover the "brains" so that both heatsinks would be able to "work" at the same rate. Considering that you will be using large amounts of caps, a small fan will mostlikely provide all the air flow you need. I am sure that your system will run cool, even with a higher draw 2s sytem.

hey guys, anyone know of a way to fix a fet that was not soldered down properly?



if the picture stops working like most of mine have, you can go to
http://imageevent.com/drknow65/rccarstuff
and look at photo #19 (be sure to click "original" on the size option at the bottom) or view #20 to see just the one fet...
I tried heating it with a soldering gun and then soldering with a 30watt iron to no avail. The minor damage that was done to one corner was done when removing the heat sink, it was already lifted which is why the sink was not attached properly to begin with.

Any ideas?

here is a link to the fet info itself if this helps or if you're just curious...

If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...

Lincpimp, there will be two fans, a pusher and a puller fan. The board will be standing up vertical with a sink on the left and a sink on the right. The brain board will be on longer wires to make space for the heat sink. So the air will be flowing thru both heat sinks equally. kind of like a tunnel with fans at both ends and the power board standing up in the middle.

You can get a better idea of what I am saying if you look at the wiring setup in my previous post.

I do plan on stepping up the voltage and motor, just in small increments.
