Dannn Posted June 18, 2015 Posted June 18, 2015 Has anyone made and used one ? Just ordered all the components, seems a very simple task ! They are about £30 to buy but components are cheap
Supporters Sitting Duck Posted June 18, 2015 Supporters Posted June 18, 2015 No coz most setups will not really really need them Plus it puts a minor strain on motor and the Rusty's guide has stopped recommending them but left info for reference only Got a few 4045's or whatever the position fet's are to go with my 3034's but as of yet if done correctly a high rof gun most likely not needed. It seems to be said a m120 & SS a couple of teeth is better way to stop double cycle and also help avoid PE Which an AB fet doesn't help when firing on full auto For most builds an AB is perhaps not needed is my feeling
Dannn Posted June 18, 2015 Author Posted June 18, 2015 Don't need the active break bit? Seems a waste to buy when the components cost £4.50 !
Supporters Sitting Duck Posted June 18, 2015 Supporters Posted June 18, 2015 Good 3034 can be built for half that price -£2:25 if you buy say 10 genuine ones Avoid any mosfet's from fleabay China component sellers They are fakes and just melt under load £2:25 will cover gen 3034, diode, 2 resistors All you need is time - put a few together at same time Decent wire n shrink wrap Best basic 3034 is your own one if its genuine Failing that firestorm £10 baby micro fet is worth a look if peeps just need a good basic tiny fet
Supporters Lozart Posted June 18, 2015 Supporters Posted June 18, 2015 It ultimately depends on whether or not you need active braking. I use AB mosfets in my guns and while yes, it may put some additional strain on the motor none of them have had an issue yet. Plus....I'm all for being thrifty but seriously ready made fets are so cheap now why would you fuck about making your own? Yes, £30 is more than £4.50 but the cheap DIY ones don't come with all the features you'd get in even the most basic Gate device.
Supporters Sitting Duck Posted June 19, 2015 Supporters Posted June 19, 2015 Depends on how many fet's you need to buy/make/fit To make just one it may not be worth buying and making it, though whilst you solder in any ready made fetbthe iron is on anyway so a few more ttzzzssstt's ain't much more agro to put your own fet together. Hence if you got it all ready may as well make up 2 or 3 basic fet's I guess. The baby baby micro firestorm fet is worth considering basic non AB fet but £10 delivered ain't bad for a one off fet. As for bells n whistle fet's - guess it is up to everyone what they fit/use in the end
Dannn Posted June 19, 2015 Author Posted June 19, 2015 The resistors come in packs of 25 they are a penny each ! And the midgets in 2 packs It's all from RS in the UK so it's good quality and there's a really good pdf guide to making them that I've found
AK47frizzle Posted June 19, 2015 Posted June 19, 2015 I'd recommened getting the AB fet because it puts the piston in the right place after firing full auto and even semi; I hate having to fire a few shots on semi afterwards to release the tension on the gearbox. Yes it "may" put more strain on the motor but i'd rather have a better performing gun with some wear than less wear and having to reset the damn thing everytime. Lozart and Josh95 2
