just to clarify then, the OP's picture is incorrect where it goes from gate to source? and should instead be gate > drain? if it is a short, then howcome the op's seems to work, cheers in advance for clearing it up ( if you do :D ) The problem seems to bee in the diagram 3 posts above. The 1404 Mosfet is marked incorrectly. It should be from left to right Gate/DraiN/Source. The center pin and heatsink are the drain terminals. -------------------- |

Ok, Sorry to necro-post here, but I've built the Mosfet with active braking and I only have one problem. I can't get it to work off the single gate wire to trigger unless I take out the 100 ohm resistor between the gate wire and the Gate pin on the mosfet.
What am I doing wrong? Can I run it without the 100 Ohm resistor? -------------------- Check out my MP5 Part Out sale:

so on the capacitor bank when attached to deans, do you have a direct wire going from positive to negative :S ?
What I saw in the picture, I can't really make to much sense of how you wire it, advice would be helpful cheers |

A little of a necrobump, but this topic is sticked (sorta), so I guess it's alright. Aaaanyways...
For some reason, DigiKey is making you buy the IRL1404 in packs of 250. I Googled IRL1404, and all I got was datasheets and two or three other sites selling it with outrageous shipping and handling charges. Are there any other good sites that sell this particular MOSFET? If not, what would be a good equivalent? -------------------- ![]() Or if you work in an office setting and you're hardcore, then you could definitely get these for ultimate realism and play CQB in your office.

I just recently started getting them from ebay from china. At $21USD shipped for 10 it isnt bad. They work well. Just search IRL1404

I'm a little terrified of electrical work, so I have a few questions on this fairly epic necro:
1) I can only assume it doesn't matter which trigger contacts get soldered in the diagram by opsic66? 2) I have a 12.8V LFP battery (40C output). Will capacitors do anything for me? 3) Can someone summarize what the various types of mosfets do? 3-shot burst and fast-brake make sense, but I keep seeing walls of acronyms that are confusing me 4) I have something like $700 invested in my primary gun, and I don't have another functioning AEG currently. At about what price range would I start to notice the benefits of capacitors/mosfets? -------------------- -aka Guns nButter
