Should I take my spring out my specna m4 if only playing once a month currently? To avoid it sitting for a period of time at tension.
The same gun sat for years and when taking apart the cylinder head, it had an imprint on it from sitting at tension for ages.
It's quick change system so no fuss.
Bought a M-lok sling mount and M-lok to picatinny rail adaptors from aliexpress for a fraction of the cost than getting in the UK.
Got an nurpol m-lok 12inch handguard from a2supplies.co.uk, come within a few days very fast delivery.
This is worrying to see as I have an Specna Arms Edge SA-E03 with this setup of motor, spring and use 7.4v lipo.
Only ran so far on one half day session with the SHS HT motor. is there a way of telling what version I have?
Bought the gun back in July 2020
Even with a 7.4v lipo? Was getting 17 earlier I think on the chrono. Should of checked what I was getting on standard gears to compare.
Could be the motor letting me down why low rps? As its only an 16 tpa apprently which doesn't help so would need to look into a higher one which probably would help you think?
I'll have a recheck with full auto when I can to see
Oh thanks, always a learning curve!
Yeah doubt I'll go that high haha! My site I go to is 25 max anyways and when I tested it earlier was giving me 17 on full auto.
Would it be worth getting a better motor or no point? An actual high torque one
Good to know it's not high torque, take it will be fine for the gearset still?
What's PME? What would cause it? And how to avoid it?
only run 7.4v at the moment have no need for more batteries thankfully
I've just put my specna back together after changing to 13:1 SHS gears and shimming them for the first time(hopefully good enough) and regressed new gears and compression parts.
Motor is an SHS high torque.
Running on fully charged 7.4 lipo
After any advice to see if it sounds good enough or any issues please? First time doing this.
Thanks

Alright mate does this sound fine to you? I can't really tell haha!
I've changed the gears to 13:1 SHS, Shimmed good enough hopefully! SHS high torque motor and 7.4 fully charged lipo

Got the compression sorted now lads, holding air with thumb over nozzle and pushing piston in.
I just put all the o seals over the cylinder to stretch them a bit and all new silicone grease on them.
Gearbox back together finally yet to try it out to make sure shimming was all good haha.
Is it worth plugging a battery to just the gearbox first before putting back into reciever? To test it runs cleanly.
Cheers
Thanks mate, yeah I'll give it a try in isolation and see if I can pin point the leak or just me being an idiot!
The piston head o ring was a bit slack but will see tomorrow when I test if I need to play with it. Thanks for the idea of stretching it though I'll keep in mind
That would make sense as been left a few years in the loft haha! Should of thought about removing the spring at the time.
Least it shouldn't affect it much now I'm running it. Hopefully compression is fine once I recheck thanks
