the plan is to simply throw a TM V2 gearbox in without the mosfet to get me going again

Lession learned, dont let clueless people ( including myself ) mess around with a gearbox
Have you tried adjusting motor height (usually a big screw in the bottom of a pistol-grip or hole for hex key)?

there are plenty of good guides on shimming you the youtubes, i would suggest if you do buy a new box to then use the old one as a learning tool and practice.
1. Good Mosfet/ECU itself wont care what motor you are running.
2. Even 22k originally would be considered "Hi-speed", because stock is usually 18k. Though nowadays its hard to find after market motors under 20k.
2. Unless your trigger contacts are damaged, don't bother replacing them. It wont impact performance with FET.
3. Imo, if your current motor is fine, you are better off investing into a Lipo. You'll get a lot better trigger response, increased ROF and so on. Rule of thumb is - don't bother with ECUs/wires/connectors/motors if you are running NiMH, the battery will be the weakest link (why are people even running NiMHs nowadays?). Plus Lipos are fun - they can act as smokebombs . If you don't want such fun - get a LiFe.

Thanks for the great infomation.

And I only have a NiMh for now as it was the same 9.6v battery i have had for 10 years and i have spent the past few years out so i missed everyone starting to use LiPo's

Planning to order a couple of LiPo's shortly for it, just looking at options for what I want.

yeah, its the piston end of the gearbox that really sounds sick, and the gears are not shimmed as they can wobble, and i really dont have the experience to fix it. I have also heard that the ICS split gearbox is prone to being loud and isnt as good simply due to its design

so the current plan is to contact Firesupport and get a Marui gearbox and get THEM To install the Mosfet and rear wiring so i can just shove it straight into my gun and get onto a field ( travel accommodations permitting ).

Fire-Support should be able to happily sort you out there. they have a couple of complete gearboxes available I believe. I do love those guys, And miss living 30 mins from the shop.

As far as my G&G trigger install went... It was not good. got everything in and cables routed but the pinion shredded one of the battery connector wires due to space issues. Not overly impressed but theres not much i can do now. So got a couple of bits and bobs shipping from the states to fix the situation.

My new LiPo for My M4 arrived yesterday for when my mosfet is working, and I cant get over how tiny it is compared to the old G&P 9.6v Ni-MH that i did have. Gotta love battery tech

Yeh, thats the one of the quirks of V2 gearboxes, I hate working on them. First time I worked on one, I manage to route the cables only on my 3rd try.

Yup. At first i started looking at trying to find a better Shell that would be easier but in the end just decided to go back to the original trigger and add the mosfet instead of trying to replace the trigger as well.

Maybe one day when I get another AEG (probably an M4 again) i will do it again. I also do quite want to try a polarstar system as they look interesting as hell.

I'm looking at a Polar* Jack for my M82. To either use it as a sniper rifle/DMR ~400fps, or to use it like a support weapon to irritate the WISWYG crowd.

HPA systems look great, but they have a very bad rep, either people find ways to turn them up after Chrono to get more power, or they crank up the rounds per second to crazy levels and hose people down at point blank range.
I wish that some sites would introduce rounds per second rules as well as feet per second, it would give support classes a reason to exist if they were the only class allowed high rates of fire and high cap mags XD

One way to get around this problem is to use gearbox as a busbar for one of the terminals. I even bolt FETs directly to the gearbox.

Increasing FPS is not something specific to HPA systems, especially with introduction of quick-change springs (even my AEG has adjustable fps). This sounds more like a lack of culture and respect for one another, than anything else. This can be usually solved by random chronys during the game and publicly banning players.

This is why i hate playing in some countries - lack of ban on hicaps and distinction between different weapons in general is maddening.

Hiya, any recommendations for airsoft sites in or around London?

I used to play at Uni (about 15 years ago!), when Firefight ran game nights in Angel. I know the 'spiritual successor' of that event is Bunker 51 near Greenwich, but apart from that, I'm pretty much out the loop.

Cheers

Only one I can think of that i have been told about recently is Ultimate Airsoft, I think that was the name anyway.



Also in other news My m4 is back up and running, just need to chrono it and make sure its not too hot for the sites i can easily attend. And just grabbed an eotech 551 clone.
