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.
