Single Sector Wanker Gun

[Fatboy40]

Some other discussions online are leading me down a dark path, in that I quite fancy building (for the fun of it) a "Wanker Gun". So far all of my airsoft toys have been focussed on a snappy semi-auto, overall range, DMR or bolt-action but I fancy building an AEG that's got a stupidly fast full auto (even though I probably won't be able to actually skirmish with it).

 

The weirdness in me though wants it to be an AEG and also be single sector, not a DSG, and a brushed motor (no HPA on this journey baby). A strong springed mid-cap magazine would also be used, I've a few PTS EPM1's, to feed it.

 

Has anyone else gone down this route and do you have any advice? (other than don't f**king do it). If you've dabbled what sort of RPS did you achieve? (as an aside I want to do this with a Double Eagle M900 AEG, so hopefully I can find a cheap used one).

Doable, but I found that past a certain threshold (say 30 rps) it's much more convenient to build a DSG instead.

 

I managed, by mistake, 36/37 RPS on a single sector gear running off 12:1s and 36k warhead but I had to shortstroke the sector by 4 teeth to achieve proper timing.. You will need a very good tappet plate and spring because the poor thing will be the most stressed component as it has to reciprocate at ludicrous speeds almost 40 times a second.

are you strict to brushed? 

if not a 50k brushless 11.1 and 18.1 will bring you straight to 40rps.

 

my opt.1 high speed (53k) did 42rps on 18:1 ss-4. no timing issue or any other headache. 

a 40k brushless will give you 33rps with 18.1 

 

obviously it's easier to get high rps with a dsg but with brushless motors anything is possible today

Mags are key. None of mine will feed fast enough to satisfy stock JG G36 gears and ~1.1J spring, stone-age brushed Big Dragon M140, 11.1V 1.4Ah 30C, and slightly chonkier wiring with Perun AB++.  I don't even know what rps it's running at because... well, the mags won't keep up.  5 round burst tends to get off 3 or 4 BBs.  Once you start down the path of wankergunnery, you're going to keep running into one limit after another, so just dive in and solve the problems as you find them.
