Skara

sounds like 11.1 is pushing her fast enough that the tappet hasn't the time to close and seal properly before the piston is firing.

might need a meatier tappet spring.

Was thinking of shaving the fin instead, but I might do it at a later date.

Eeeh, we'll see how she does tomorrow

Yeah likely tappet timing, full fin & a delayer

especially if a long delayer like this...

not as enormous as some sectors like JG one...

now that is fucking silly, it is a one piece delayer

that has a pin cast into delayer that goes through

both halves of sector gear, so if you remove it

you need to drift in an old axle from another sector

to give you a pin to mount a more sensible clip...

You can just slip on a sleeve from old gears/sector

to add a whisper more retraction than delay as such

like what is only option on a DSG...

For the game, run it mostly on 7.4v perhaps

or 11.1v if running support for example

Wait until you need to open her up again

then either:

remove/change delayer

or

trim tappet

or

lop a couple of loops off tappet spring

if you short stroke it at some point

then you you should trim off about 5mm from fin

not insane stuff like DSG

but an inbetween full & DSG fin so to speak

TBH running it full stroke at 29~30rps at 325fps

is kinda sailing a bit close to wind for my liking

so really stick to 7.4v...

What motor is in there ???

Think that is a ZCI 22tpa/20~22k rpm as 30k would be like 25rps

Something like a 25k would have just put you into the 20's

but tbh you are pretty damn close to what you wanted

but low current/amp draw, snappy response etc...

short stroking might not be an option on a 400~450 barrel AK

So overall you are at what you sought to be

plus when the v3 Perun arrives you'll have pre-cocking

so all's well that ends well as they say

I'd be tempted to look for a slightly quicker motor

not much quicker, but if you come across a cheap 19tpa

then that could fit the bill

but 30rps on full stroke 325fps is getting a little close

and tbh as it stands atm on 7.4v, touching 20rps

that's a good rof on a full AK, with snappy response
