Ok, So I installed a chilli and 2x2 stack. Can anyone vouch if its worth it to upgrade to 2x3. Yes, i want more speed.

Thanks

What kind of FETs are you using?

If you have a 2x2 stack of 3010's, then 2x3 is worth it.

If you have:
2x2 4562; 2x2 8858; 2x2 SP8M4 -> Then the difference in power+speed is not so much that it is noticeable to most people.

The main benefit of going 2x3 with any FET is to help keep the FETs from failing. Some hot motors, including the CHILI, can put high Amp loads on FETs (Especially if you run high gear ratios). The 2x3 stack should run cooler with less risk of blowing up your FETs and board.

But for speed alone, the difference between 2x2 and 2x3 usually isn't much, if at all.

Hope this helps!:D

Adding more fets won't really make your car go faster. I've only seen a few people really control the speed of the chili and if you really want more, just turn up your throttle high point :p or break in your motor....

What about just leaving the stock 3010 fets and adding stacking the Fairchild 8858 fets on top on a 2.4 board?

I am getting lazy and don't want to remove the 3010 fets :D

Yes - Adding a 8858 layer to the OEM FETs works for increasing motor handling capabilities so you can run hotter motors. I'm not exactly sure if this will provide the maximum increase in punch-factor and speed as a full swap of 3010's for say 8858's.

I first heard of CT do this a couple years ago. There's a post or two buried in the forum here, somewhere... The +'s of just adding a layer are no risk of lifting a pad; Performance enhancement/Amp-handling increases; Simpler + Time-saving.

For All-Out performance, I go full FET replacement.:D I probably wouldn't be able to tell the difference between the two setups, but just in case, I prefer to use only one type of FET.

Thanks for the info.
