Going to have a play around with an SLR ION to see what it can do and hopefully learn a few things.
Its already got a piston and flat piston head with good sized holes and the barrel has been changed from 7.3 to 7.5.
It has a full cylinder and barrel extension at the moment but that barrel extension will get removed and the barrel taken back down to the stock 280mm
Not looking to spend big bucks but in the spare parts tub I’ve got a T238 29k motor, an eshooter basic mosfet and a near new set of SHS 16:1 gears so the plan is to have a go at putting those parts in. I might have a go at radiusing the gearbox as well.
I’ll pickup up an 80% cylinder to replace the full cylinder. Anything else worth doing while I’m in there? Short stroking?
16:1 and the 29k motor will be pretty nice performer and easy build.
The 80% cylinder will be a big plus to a 280mm barrel. Recommended.
I would say a M rated spring to suit your desired FPS will help, stock springs are a bit short even though they are stiff enough for 300fps give or take. I generally use m100s in most things, and short stroke to suit fps requirements, though removing 1 tooth may be needed depending on the piston and head used so the piston doesn’t bind and jam the gearbox before it releases.
I would recommend a nozzle, they are quite leaky. I have been trialling (and sending out to others to trial) the “LDT style” nozzles I sell, so far they have worked in cymas I have tried, with the side effect of oversized gels wont feed, which I would say is a benefit lol.
Couldn’t get my hands on an 80% cylinder so its back together temporarily with the OG 70% cylinder, 16:1 gears and an M110 just because that’s what I had on hand.
Did a quick chrono check in the garage so I’ve no idea what the accuracy is like but I’m extremely happy with the initial results
Needs a field test but I feel like that FPS and RPS is pretty spot on for where we play
Nice results, well done! Hopefully accuracy is pretty decent, I often see decent accuracy in barrels 240-280mm, probably my favourite lengths to work with too!
Accuracy today was pretty darn decent with the slightly softer Summer Cat Milky’s, between that and the new rate of fire this blaster cleaned up today. Only real issue is the bloody tiny Cyma magazines, need to do something about that.
Have an 80% cylinder, new cylinder head and nozzle on the way to try out next.
Haven’t installed the eshooter basic mosfet, still outside my lane at the moment but I’ll have a crack once everything else is in and humming along.
Bit of a weird result, FPS dropped from 320 down to 270 with the odd gel dribbling out of the barrel. Might go back and just replace one part at a time and see if I can narrow down the culprit.
That is where at some point the sector gear has gone backwards into the tappet.
You can press and or shave it flat, it should be fine. But does mean it is worth checking the anti reverse latch (if the anti reverse latch spring broke at some point this can happen)
So that glue is not fit for purpose, CA glue next.
